Investigating crime scenes allows law enforcement to uncover physical evidence that can be used to find out what happened. Benjamin Ambrosio, as a police officer on the New York City police force, has been investigating crime scenes for over ten years. The circumstances of the scene, dictate the approach police officers use to process the scene. Below, find the basic steps involved in investigating a crime scene.
The first thing to do is to locate the focal point of the scene. From here, investigators spread out to establish an area that is large enough to contain any physical evidence that may be present.
The area must be quickly secured and a common entryway needs to be established. Every person that has contact with the crime scene will add or subtract from the material of the scene.
Before any evidence is collected, the type of crime must be established. This requires gathering information from witnesses or persons of interest.
A primary walkthrough needs to be performed in order to prioritize the collection of evidence.
Once a plan is in place, those working the crime scene conduct a thorough investigation and collect all evidence.
For quality control, a secondary survey of the scene is conducted.
Once all the evidence is gathered, a detailed inventory log is created to make sure everything is accounted for.
The more thorough the team is that is conducting the investigation, the more accurately determine what happened. Benjamin Ambrosio has been responsible for managing crime scene investigations since becoming a New York City police officer in 2005.
