The Process Of Investigating A Crime: Infographic

by Nathan Zachary

When a crime is committed, it is the job of the police to investigate and try to solve the case. But how exactly do they go about doing this?

There are many different steps that are involved in investigating a crime, and these can vary depending on the type of crime that has been committed. However, there are some general steps that are usually followed in most cases.

The first step is to gather evidence. This can be done by talking to witnesses, collecting physical evidence from the scene of the crime, or reviewing security footage.

Once the police have gathered enough evidence, they will then try to piece together what happened and who was involved. This process can be difficult, and it may take some time before they have a solid theory of what took place.

Once the police have a theory of what happened, they will start to look for suspects. They will interview potential witnesses and look at their alibis. They may also use surveillance techniques to track down suspects.

If the police have enough evidence to charge someone with a crime, they will make an arrest. Once an arrest is made, the suspect will be brought to trial where they will face justice for their actions.

The investigation of a crime can be a long and complicated process, but there are typically five main stages that law enforcement officers will go through in order to solve a case. These stages are:

  1. Gathering information and evidence
  2. Analyzing the information and evidence
  3. Identifying suspects
  4. Questioning suspects
  5. Collecting more evidence (if necessary)

What is the Investigative Process?

The investigative process is the process that law enforcement agencies use to gather information and evidence about a crime. It is important to note that this process is not always the same for every crime and that different agencies may have different procedures. However, there are some general steps that are usually followed in most investigations.

The first step is to receive a report of a crime. This can come from a victim, witness, or other law enforcement agency. Once a report is received, the next step is to determine if a crime has actually been committed. This is done by looking at the facts of the case and seeing if there is enough evidence to support the claim that a crime has been committed.

If it is determined that a crime has been committed, the next step is to identify suspects. This can be done through eyewitness accounts, surveillance footage, tips from the public, or other means. Once suspects have been identified, the next step is to gather evidence against them. This evidence can include DNA, fingerprints, video footage, or anything else that can help to prove that the suspect committed the crime.

Once investigators have gathered enough evidence, they will then present their findings to prosecutors. Prosecutors will then decide whether or not to charge

  4. Ask open-ended questions. Open-ended questions will allow the witness or victim to give you more information than yes or no answers. They also help to keep the conversation going if there are lulls in the conversation.
  5. Listen carefully. It is important to listen carefully to what the witness or victim is saying. This includes paying attention to their body language and any nonverbal cues they may be giving
