Tips for children detectives

1. How do you make your own detective club?

What do you need to set up a detective agency?

Room with seating

If you want to set up a detective agency like the IGEL team, you need a space with plenty of seating, depending on how many employees you hire. Lisa, Ingo, Georg and Enzo use Ingos Zimmer at home. When they are away from home, they often set up camps somewhere, or use one of the hotel rooms in which they are booked.




If you detect in areas, it will not work without maps, as you may already know as an IGEL team fan. You attach this to a pin board.

Create the pin board yourself

You can also make these yourself. You will need a corrugated board, pins, colored paper and a pair of scissors.

The corrugated board serves as a pin board.


To make flags, cut the paper into small pieces and skewer them with the pins.

Now you put the pinboard on a dessert or a dresser or hang it on the wall. Then you hang up your plan or your map and can mark certain places with the flags.

Make observation sketch

A sketch is made when an observation is planned. The observation sketch is stapled to the bulletin board and the watch positions are assigned with flags.


Why should I stake out a card?

If, for example, you have determined in an animal search and posted leaflets, you can stake out the area with pin badges on the city map. So you can see at a glance where the flyers have already been posted and which area is still outstanding.

In an observation sketch you put off positions, which the detective members should take during the observation.

Install the surveillance tongue

You want to see if someone has entered your room in your absence?

No problem. Just build a surveillance check in the form of a tongue.

Take a piece of transparent tape, glue it together so that a small glue edge remains. Attach this tongue as high as possible to your door.


Now, when you leave your room, be sure to push your tongue inward as you close the door. If someone enters your room, he will not notice the adhesive tongue. If the intruder closes your door, the tongue will fold outward.

2. Detective Equipment

As a detective you should always have these items with you:


Fingerprint Set (self-made)

Fingerprints can be found at almost every crime scene. Fingerprints are different in every person, which makes a clear assignment possible. All members of your detective agency should create fingerprint cards to prevent them from accidentally pursuing their own tracks.

How to make your fingerprint set yourself:


For the graphite powder:

Put paper on the table.

File the pencil lead on the nail file and place in a container. For example, in an empty matchbox.

For your set:

You take a plastic box, put in the following items and have your own fingerprint set.

• graphite powder

• Transparent tape

• Soft brush


• Document for gluing the impression


You need the chalk to mark paths or tracks.


meter band

The meter tape is used to measure footprints.



The flashlight you need to spy on dark corners, rooms or caves. Without flashlights, the IGEL team would often have been stuck.



The binocular is an important tool of a detective for the observation of suspects.


Notepad and pen

Whether crime scene sketches, telephone numbers, names or similar. A notepad and pen is part of the basic equipment of a detective. Ingo makes notes on his block in almost all adventures.


magnifying glass

You need the magnifying glass to find tracks. For example, hair, lint and the like.

Photo camera

With the camera, evidence, traces or suspects are photographed.



The whistle is what you need when you are in danger to attract attention.




The tweezers are used to pick up hair or lint.


proof bag

Found evidence is packed in a bag. You can also use freezer bags.

Door Opener Set

Ingo always has his door opener set with him and has been able to free the IGEL team from many dangerous situations. If you get locked up, it is advisable that you know how to open locks and what tools you need for them.


For a cylinder lock you need 2 tools:

1. Stretcher:

2. Picker

With a hairpin and pliers, you can easily make these two tools yourself.



The stretcher: is bent in an L shape and used to tension the lock.



The picker looks like a small walking stick and is used to push the locking pins down.

Procedure when opening a cylinder lock:

The strecher is inserted into the larger opening of the lock. Then, a rotational movement in the unlocking direction of the lock is performed to hold the rotary cylinder to tension.

Now insert the picker into the narrow opening and push the pins down. When all pins are down, the tensioner will continue to turn and finally the lock will open.

For practicing a padlock is very good.

Open the beard lock:

To open a beard lock, you need a lock pick. 

You can make a lock pick yourself from the handle of a bucket or a large nail. To do this, a nail or a piece of the metal handle of a bucket is taken and one side bent over as a handle, the other side is bent over and flattened, it serves as a key bit. Such a key fits on any moustache lock with a little sensitivity.


Put together a door opener set:

So you take the tensioner, the picker and the lock picker and put these three tools into a box. The door opener set is ready.


3 Which papers do I need for my detective agency?

detective agency deed

You can download the detective agency certificate from the IGEL team website. It practically represents your certification as a detective agency, in which the name of the detective and the chairman or the chairman are named. You can hang them on your wall. You also have the possibility, after filling in the certificate, to have your detective agency registered free of charge on our homepage under "Detekteien". So your customers can also find you on the Internet.


Create your detective agency certificate

Download your free detective agency certificate from our website. Print it out, fill it in and register for free on the IGEL team website. 


detective passes

Misunderstandings with uninvolved persons may occasionally occur during an investigation. In order to be able to identify yourself in such a case, you and your staff carry a detective ID with you.

(The passes can also be downloaded from our homepage)

This will be printed out, filled in and signed. Finally, a passport photo is pasted in.


Make the IDs for your detectives.

Create your members their own detective ID card so that they can identify themselves at any time.


fingerprint document

If you have to take fingerprints, they will be pasted on the fingerprint documents so that they can later be assigned to the location where they were found.

Create your members' fingerprint documents.

It can happen that detectives leave their own fingerprints at the crime scene due to carelessness. Therefore it is advisable to have the impressions of the members ready and to compare them in advance.


personal file

The personal file is important for recording suspicious persons.


investigation file

Information on the case is entered in the investigation file. The investigation file can also be downloaded from our homepage.


4. Practical application

Measuring the footprint 

A footprint is measured, from which shoe size is calculated.


(track length + 1.5cm toe clearance)* 1.5 cm factor= shoe size 


Example of a track with a length of 25 cm: 

25 cm= (25cm+1,5cm) x 1,5= shoe size 40 



After the footprint has been measured, it is photographed for sole profile purposes. The data is then compared with the soles of the suspects' shoes.


Take fingerprints

Objects are examined for fingerprints. The found impressions are pasted onto a fingerprint document. Then the suspects produce comparative prints.


Step 1:

Use a brush to carefully apply the graphite powder to the object or to the surface.


Step 2:

Remove with transparent adhesive tape and stick on a document.


Adjust lint sample

Sometimes you find lint on hedges, bushes or trees, which can come from a jacket or sweater. These are compared to lint on the clothes of suspicious people under a magnifying glass or microscope.


Adjust hair sample

It can happen that perpetrators leave hair at the scene of a crime. The hair is compared with the hair samples from the suspects under the magnifying glass or under the microscope.


Vehicle surveillance

To check whether a vehicle has been moved, make a small mark on the wheels with chalk.

Alternatively, you can put a small stone on the tire. If the mark is moved or the stone has fallen, you can see that the vehicle has actually moved.


Door control

If you want to find out whether the person had left the house, you can put a piece of paper or cardboard between the door gap as a surveillance check.

If the surveillance control has disappeared or fallen down, you know that the target had left or entered the house.

Important notice:

This control technique has recently been used frequently by burglars to check whether the residents are on holiday. Often plastic parts are used, i.e. eyes open. 


Building a monitoring alarm

There are situations where you need to build an alarm so you don't miss an intruder during long observations.


You need:

2 branches

sewing thread

bells (usually found in Christmas decorations)


Put the branches into the ground to the left and right of the path.


Tie the sewing thread to a branch and guide it along the path.


Attach bells to the end of the thread and hang over the other branch.


If someone runs through the thread, the bell will ring.


Exploration of forests or caves 

A cave exploration or a forest hike can quickly lead you astray. The good reputation of a detective would be ruined. To prevent this from happening, arrows are drawn on a tree or on the rock face every time you turn off with chalk. This way you always keep your bearings.



When questioning witnesses or suspects, it is important to repeat questions in a different wording to identify possible contradictions. In addition, you can also include trick questions. Prepare yourself well for the interrogation by taking notes beforehand.


Example of a trick question:

Detective: "Where were you at noon yesterday?"

Suspect: "I was at dinner."

Detective: "What did you eat?"

Suspect: "Noodle salad."

Detective: "Were you with someone who can testify to that?"

Suspect: "No. I was alone."

Detective: "Was the potato salad good?"

Suspect: "Yes, very good. I like potato salad."

Detective: "Didn't you say you ate noodle salad?"


5. Recognize lies

During an interrogation, it's important that you know if someone is lying to you. Here are a few behavioural problems that may indicate a lie.


The interviewee often grasps his face

If the person interviewed often touches his face, he feels insecure. That could indicate that she's lying and afraid of giving herself away.


Eyes do not lie

The eyes of the respondent show whether he is making up a story or trying to remember. When you have memories, you automatically look up left, so you look up right. When you make up a story, you look up to the right, so you look up to the left.


The collar

If the interviewee often touches his collar, it means that his collar becomes too tight or that he is left breathless, which also points to a lie.


Eye contact

If the respondent constantly evades your gaze, he has something to hide. But if he keeps staring at you and doesn't dodge your gaze, he's lying too, because he tries to hide his lie by the constant eye contact.


6. Sharpening the senses

Train your sense of balance:

The detectives are standing on one foot. Who lasts longer wins. It may sound a bit simple, but the sense of balance is very important for detectives, because even in uncomfortable positions you should be able to observe and photograph a target without the photo being blurred afterwards.


Training the sense of touch:

To do this, take an opaque bag and put in various small objects. Be aware that there is no object that could injure yourself!



The bag now goes in a row. Each detective reaches inside, says what he has in his hand and then pulls the object out. If it's right, he gets a point.


Training the sense of smell:

First, as much odorous substances as possible are prepared. These can be nutmeg, peppermint tea bags and similar things. The more, the better.



Now one of the detectives gets his eyes blindfolded and he has to sniff out what he gets held in front of his nose. That's how every detective is tested. Whoever guessed the most smells wins. The sense of smell is important for a detective to be able to assign traces at the crime scene in advance.


Training the sense of hearing:

First some cups are prepared with small pieces of material. You can use uncooked rice, coffee beans, dry peas, lentils or even buttons.



The detective to be tested is blindfolded. Now the first material is noisily decanted into an empty cup. The detective has to guess what it is. Once all materials have been decanted one after the other and the statement of what has been tested noted down, it is the turn of the next detective. The winner is the one who guessed more materials correctly.


7 Which cases can I treat as a detective?

Besides solving theft crimes, you have many other options as a detective. The IGEL team is also asked for help in various cases.

Here are a few examples of the detective agencies you could run:


Information for environmental detectives

The following explains how your work as environmental detectives

and what tasks and activities the work could look like.

as an environmental detective. 


The Garbage Dischargers 


Inorganic materials such as sheet metal, plastic, cigarette butts or the like, form toxins when they rot. These are flushed into the groundwater with the rain and thus end up in drinking water. Drinking water is used to pour food and therefore the toxins eventually end up in the human body through food and drinks, where they can do great damage. 


Perpetrator's profile:

Garbage unloaders are people who throw their garbage or scrap into nature in boxes or use the forest as a scrap yard or garbage dump. 


Garbage unloaders contaminate food and drinking water. 


The environmental detective's job:

Here the environmental detective takes photos first. He then uses gloves to search the garbage for names and addresses. If he finds what he is looking for, he hands over the documents, on which names and addresses are clearly visible, together with the photos and a small report with a description of the facts to the responsible public order office. 


The barrel overfillers 


Garbage lying next to a barrel can be carried into the environment by the wind and washed through by the rain. This is not only unattractive and disturbs the landscape, but can also cause harmful substances to enter the ground and groundwater. These toxins are also transferred into food through soil and water. 


Perpetrator's profile:

The barrel overfillers usually come by car and dump their waste next to overcrowded bins and containers, although there are empty containers a hundred metres away. Often they are always the same people. 


Barrel overfillers are therefore responsible for littered landscapes, polluted drinking water and poisonous food. 


The environmental detective's job:

The environmental detective lies in wait and takes photos of the polluter, who shows him on different days at the same rubbish collection point, while he dumps his garbage next to the containers. These photos will be handed in together with a report to the responsible public order office. 



The throwers 


Inorganic substances such as sheet metal, plastic, cigarette butts or the like, form toxins when decomposed. The toxins are produced by the degradation of paints, adhesives, plastics or alloys. These are washed into the groundwater with the rain and end up in drinking water and above in the human body, where they can cause major damage to health.


Perpetrator's profile:

The disposables are always the same people who lack environmental awareness. They simply throw their cans, bags or food leftovers onto the street or into nature, although there is a dustbin just a few steps away. 


Disposable disposables contaminate food and drinking water and thus damage people's health. 


The environmental detective's job:

These people are also shadowed by the environmental detective and photographed during their actions on various days. The pictures are also submitted here together with a report to the responsible public order office. 


The energy waster 


Electricity production consumes natural resources and pollutes the environment with exhaust gases or toxic residues, resulting in global warming. Global warming not only causes storms, but also drought that devastates vast areas of the earth. Nothing grows in the desert and as it expands, the food production area becomes increasingly scarce, which will cause famines. 

Energy-saving lamps also pollute the environment during production and disposal due to toxic substances and pollutant emissions.

Electricity production from wind power or solar energy is also harmful to the environment. Solar cells and wind turbines require a lot of energy for their manufacture and also produce harmful exhaust gases. The more they are used, the greater the wear, which is also at the expense of the environment. Consequently, only environmentally conscious and energy-saving handling can relieve the environment. 


Perpetrator's profile:

Unfortunately, you don't have to search long to find an energy waster. You can also meet him in your own house. He keeps lights on when there's no one in the room. He also likes to let huge amounts of water run forward and prefers to take a bath instead of a shower. He also leaves the fridge open for a long time and lets computers or televisions run, although nobody uses these devices at that time.

The energy waster heats his house or apartment to maximum temperature in winter so that he can sit around in a T-shirt or undershirt instead of putting on a sweater and lowering the room temperature.

Outside, one recognizes the energy waster by the fact that he lets the engine of his car run long before the departure or that he drives short distances with the car, instead of mastering these on foot or with the bicycle. 


Energy wasters trigger climate change, storm disasters and water and famine. Thus they are responsible for hunger and storm victims. 


The environmental detective's job:

The task of the environmental detective is to draw the energy wasterer's attention to his misconduct and to show him how harmful and expensive his behaviour really is. Mostly these people have an understanding and are even grateful for the instruction in environmental protection and energy saving. 


The plastic bag wasters 


Plastic bags not only require vast amounts of resources and energy for production, they also produce a great deal of indestructible waste. Despite today's recycling methods, more and more plastic waste ends up in the oceans and in the ground. As a result, the toxins contained in these substances pass into plants and animals and are ultimately absorbed into the human organism through food. The effect of plastic residues on the human body has not yet been fully tested and therefore no one is yet aware of the health consequences.

Avoid plastic bags altogether. 


Perpetrator's profile:

You can recognize wasters of plastic bags by the fact that they collect bags in drawers and bring new bags with each purchase. 

Plastic bag wasters poison food and drinking water. Thus, they are responsible for diseases and deaths caused by insidious poisoning. 


The environmental detective's job:

The environmental detective addresses the plastic bag waster and makes it clear to him how much he harms the environment. Often these people have an insight and thus change their behavior. 


Paper bag waster 


Paper bags are also very polluting because paper is made of wood. For the wood, trees have to be felled and entire forests have to be cut down. Forests support oxygen and climate regulation, as well as the degradation of pollutants and air filtration of the earth, which in turn influences the weather. 


Perpetrator's profile:

Paper bag wasters can be identified by the fact that they collect the bags in drawers or cabinets and bring new bags with them every time they are purchased. 

Paper bag wasters destroy forests and destroy the world's climate. Because the world's climate is important for agriculture, this entails water and famine. As a result, paper bag wasters are responsible for water and famine. 


The environmental detective's job:

An environmental detective points out that shopping baskets or textile shopping bags, which can be used again and again, are a better solution to protect the global climate. 



Information for animal detectives

The following explains what your work as animal detectives could look like.

Suppose you're told to find a missing animal.

You and your detective colleagues, you contact the client by mail, phone or in a personal meeting accompanied by a PEL (Personal Adult Bodyguard). 


Putting up the want ads:

You will need a picture of the beast that will be posted on the notice. The name, the species and the breed should not be missing on the notice. It should be indicated where the animal was last seen. Finally, enter the e-mail address of your detective agency or optionally the client's contact details.

The client should make enough copies of the search poster to hand over to you. 


Wanted place Distribute:

As animal detectives, you go through the place as a closed group and hang up the notes where people spend a long time. For example in shops or at bus stops. You start where the animal was last seen and work your way from there to the outskirts.

It would be good to make a sketch of the settlement, which you hang on your pinboard to mark out the worked area with flags, so that you always keep track of where you have already distributed the slips of paper and which areas are still outstanding. 


Wanted ads in animal shelters:

If there are animal shelters in your place, leave a note there as well, so that you or your client will be informed as soon as the animal is handed in there. 


In the surrounding area:

Together with your detective colleagues you search surrounding parks and green spaces for the animal. Depending on the species, take a container or a line with you. If you find it, stay with the animal where you are and ask the client to pick it up there. 



Inform the client about what you have done so far in the search for animals. For example in the range from x to Y. In animal shelters x and y notes handed in.

Inform the client to keep you informed. If the animal was found without your knowledge, the client should inform you immediately. 


What happens when a finder answers?

If you receive a message from a finder, insist that your client pick up the animal in person. Inform him so that he can contact the finder and take care of the collection. 

Never pick up an animal yourself, because something could happen to it in your care or an alleged finder wants to lure you into a trap. In addition, the client may be able to pay the finder a reward upon collection. 


Order completion:

Once the animal has been found, collect the posters and take them back to the client. Teach the shelters where you left a note that the animal was found. 


Information for Security Detectives

The following explains what your work as a security detective could look like.

Suppose you're hired to give advice on building security.

You and your detective buddies start counseling outside the house. 


Search for crooks:

Before you enter the house with the client, look around the walls, fences and walls for crook signs and advise the client to always pay attention to such signs and, if they are present, to wipe them away immediately. 


The way to the front door:

See if the way to the front door is lit up at night. If not, you can advise the client to install solar lights. An unlit path is an invitation for burglars and an accident hazard for residents. 


Lighting at the front door:

In most cases there is exterior lighting in front of the front door. Ask the client if it is equipped with a motion detector, if not, please retrofit it. Lamps that switch on when in motion cost only a few euros and make an enormous contribution to safety. 


The front door:

Now look at the front door. Does it look stable and does the lock look secure? You can advise your client to additionally secure the front door from the inside with a wedge at night. A part of a wooden clothes peg is completely sufficient as a wedge so that the door can no longer be opened from the outside. If there is normal window glass (without wire mesh) in the front door, the client is advised to cover it from the inside with a UV protective film. When the window is broken, the film will hold the glass together and thus contribute enormously to safety. 


The rooms:

Check if there are smoke detectors in the rooms. If not, urge your client to install smoke detectors. They only cost a few euros. Although smoke detectors do not provide protection against burglary, they can save lives for the residents. 


Windows and balcony doors:

Look at the windows. The glass should be secured with a UV protective film to make impact more difficult. In order to make the windows more secure, it is recommended to the client to install additional small sliding bars at least on the lower floor. The bars are available for a few euros in any DIY store and can greatly improve the stability of a window. Shutters can also be secured against being pushed up with additional bolts, hooks or eyelets. 


Conversational security consulting: 

Avoid holiday announcements:

Explain to your client not to announce vacations or excursions on social networks. They should also refrain from creating automatic e-mail responses indicating that they are on holiday. The same applies to information on answering machines. Such holiday announcements are a found food for burglars. 


Carry out a house check:

Explains to the client, if he will go on holiday, he should hire someone to look after the house or apartment from time to time. The inspector should pay attention to crooks and check the front door for surveillance checks. Monitoring controls can be plastic plates or paper snippets stuck in the door gap. Burglars use this method to check how long a door has not been opened or whether residents have been away from home for longer. If such a snippet is found, it should be removed immediately.


8. Observation techniques

This chapter explains some observation techniques. Remember that there should always be at least three of you if you are in danger.


To follow a target, you should wear quiet shoes. The target should be followed at a distance that is not too small, otherwise, they could become suspicious. It's always better to temporarily lose sight of the person than to get caught.


Review technology

As the name suggests, the retrospective technique is a look backwards. To do this, place a pocket mirror or stick a mirror foil in a fold-out folder and observe the target person through the mirror. But be careful, if the object comes too close, close the mirror case quickly.


Eye Rolling Technique

You can use this technique very well if you wear mirror sunglasses through which you do not recognize the eyes. You take a book or a picture in your hand, pretend to look at it and in reality you observe the target person. Make sure that the head always remains in the same lowered position while the eyes follow the object.


Hearing aid amplifier

With the amplifiers, you can hear through walls. You can simply take a funnel-shaped cup, place it against the wall and put on your ear. The vibrations of the sound waves are conducted from the wall into the cup, bundled there and transmitted to the ear.


Natural sound processor

If you are on the road and want to eavesdrop on someone, you can strengthen your hearing enormously by putting on your hands. Place the hollow hand behind the auricle and press it a little forward. This can only be done with one ear, or with both ears at the same time.


Hidden Observation

As the IGEL team has done on many adventures, you can also watch hidden. It is advisable to bring a seat cushion or a seat mat so that you can kneel or sit comfortably. The best place is in a hedge. From there you can comfortably observe the target with binoculars.


9. Traces and clues

This chapter explains what the traces found at the scene reveal about the perpetrator.


A found hair is examined under a magnifying glass or microscope. You can determine the hair color, hair length, and hair texture.


For example: 

When a hair is blonde, you know the killer is blonde. If the hair is long, the perpetrator has long blonde hair. If the hair is curly, the perpetrator has long blond curly hair.



The lint reveals something about the offender's clothes. First and foremost the color. Depending on where it was found, you can also determine which garment it is. If the lint is found in a hedge, for example, you can determine whether it is a pair of trousers or a sweater by the height of the find.


Cigarette butts

Cigarette butt at the scene says the perpetrator is a smoker. It may also be possible to determine the cigarette brand if the label can still be read. If there is lipstick on the cigarette, one can assume that it is a perpetrator.



Footprints tell a lot about the shoe.  The shoe size, whether the shoe has a heel or flat soles, whether the soles have a profile or are smooth.


10 Secret exchange of information

The secret exchange of information (secret communication) deals with the topic of how to exchange information unnoticed among confidants.


Why do we need secret messages?

If a person is under suspicion, this is always a delicate matter. If this information gets out, there is a danger that it will spread and eventually end up with the suspect. This can significantly affect the investigation.


Hand Signals and their Meaning

During an observation it is important to master a few hand signals so that you can communicate with each other unnoticed. If these hand signals are practiced well, then nothing stands in the way of a good communication even over a certain distance. 


In order not to attract attention with the hand signs, these are linked with natural movements.

For example, with the sign "Successfully finished", where the middle and index fingers are spread, you can stroke your middle finger over your eyebrows. You can also stroke your middle finger over your eyebrow when you see the sign for "Retreat" or "Continue". 


With the hand signal for "The trail is hot" (thumbs up), you can pretend to look at your thumbnail. Just like the sign "The track is cold", (thumbs down).

When the sign for "waiting" is shown, the palm of the hand can be stroked over the forehead with the back of the hand.

The sign for a meeting, in which four fingers are shown, can be indicated by stroking over the chin with a flowing movement.

With the fist, as a sign of "access", one can look at the palm of one's hand, then clench one's hand to a fist.

The hand signals must be practiced diligently so that they appear as natural as possible.


Secret alarms

As IGEL-Team fans know, Enzo can imitate great animal voices and is therefore perfect to stand guard. With animal voices he alerts his friends if danger threatens.

Train a few animal sounds, such as a dove, an eagle owl, a wolf, a cat or something similar, so that you are prepared for the next guard.


11. Professional equipment for advanced users

As a professional, your equipment gets better and better over time. If you have found your calling as a detective, the following articles may appear on your wish list in the future, if you do not already have them:



To stay in constant contact with employees or to call for help in an emergency.


MP3 recorder

With the MP3-recorder you can secretly record confessions or remarks.


Camera bug ballpoint pen

A camera bug ballpoint pen is an inconspicuous ballpoint pen with a built-in film camera. You can use it to secretly take pictures that can later on incriminate the perpetrator.


12. Explanation of terms


Communication is called information exchange of any kind. This may be a conversation, correspondence, sign language or any other form of information exchange.



Observation is the observation of the suspect or an object. One observes the person whether he could possibly betray himself through actions.



Evidence is evidence at the scene of the crime that refers to the perpetrator. For example, if an identity card is found at the scene of the crime, it is most likely proof that the perpetrator is the owner.



Evidence, unlike evidence, is just evidence.

For example: They broke into a video store and found a fingerprint of Mrs Mustermann. This proves nothing, because Mrs. Mustermann can be a member of this video store and have left her fingerprints when she rented a film during regular opening hours. If it turns out that Mrs. Mustermann is not a member, the likelihood that this is evidence increases.



search for clues

The search for clues is defined as a tour of the crime scene and a visit to the vicinity of the crime scene. You look for clues. That is, circumstantial evidence. These can be fingerprints, footprints, lint, hair, personal items or similar.


Reconstruction of the crime

Reconstruction means that one reconstructs the course of events based on clues and evidence or tries to comprehend them. This creates an overall picture of what happened. Sometimes it is important to research (to investigate) in order to put together the overall picture of what happened.


motive for the crime

The motive for the crime is the suspect's motive.

What good does he do?

What should have led him to do this?

Who could have hired him?
