Managing Suspects and Groups

A detective with a municipal police department is investigating a local gang in connection with a series of homicides. A colleague tells him that a suspect in a recent shooting incident might have ties to the gang that the detective is investigating. The detective reviews the shooting case and notes that witnesses identified the suspect using an obvious alias. He searches the suspect records for the alias and finds a match, confirming that an individual using the alias and matching the suspect’s description is associated with a gang he believes is involved in several shooting cases.

The detective accesses the gang’s group record and reviews the hierarchy to determine the suspect’s relationship with other gang members. He finds that one of the suspect’s subordinates is a previous shooting victim. The detective uses an informant to gather additional information, placing the suspect at the recent incident at the time of the shooting. The detective determines that the suspect might have had a motive and the opportunity to commit the previous crime. He updates the suspect record with the activities he performed and the notes he gathered, and then generates a Case Overview Report about the shooting investigation to use in requesting a warrant for the suspect’s arrest.
