Physical Evidence — When physical evidence is collected from a crime scene, it is taken to the property or evidence room of the law enforcement agency that has jurisdiction over the crime. There, the evidence is catalogued and stored, pending further decisions about the case. At the request of a law enforcement investigating officer or a prosecutor, evidence from a crime may be sent to the crime laboratory for analysis.
Eyewitness Evidence — Police often ask eyewitnesses to identify a suspect from a lineup or an array of photos. A lineup or photo array involves placing a suspect or a photo of a suspect among people who are not suspected of committing the crime (fillers) and asking the eyewitness to identify the perpetrator.
