The investigation of a crime is a vital aspect of the criminal justice system. Police and investigators follow strict legal guidelines in their efforts to uncover the truth. If you have been accused of a criminal act, a criminal lawyer can help you understand how the police investigation process works.
In some cases, law enforcement officers may catch the perpetrator at the scene of a crime and arrest them on the spot. This is an ideal situation, as it allows the investigators to focus on building a strong case for prosecution in court. However, many crimes are not caught by the police at the time they occur, which leaves the police to investigate the crime after it happens.
When an investigation of a crime begins, the police will first send officers to the scene to secure it and make initial assessments. This is important to ensure the safety of any potential witnesses and prevent contamination of any evidence at the scene. The police will also document the scene, which can be used to identify suspects and establish a chain of custody in the event that the evidence is ever contested in court.
Once the police have gathered all relevant information, they will begin interviewing witnesses and suspects. These interviews are conducted separately so that each witness can give their own recollection of the events without interference from other witnesses. Police will also use a variety of technological tools to aid in their investigation, such as surveillance devices and public records databases.
