How to Become a Criminal Investigator With the Wilmington
Police Department

As Delaware’s largest city, and because of its proximity to surrounding metropolitan areas, Wilmington experiences a higher-than-average rate of crime. Of the many thousands of calls for service that the Wilmington Police Department receives every year, more than 1,000 are related to particularly violent crimes and felonies. The police department refers these cases to its expert detectives, who in 2012, responded to 26 cases of murder and 474 robberies among many other felony crimes.

Detectives work in several specialized departments within the Wilmington Police Department:

  • Criminal Investigations Division
  • Financial Crimes Unit
  • Drug Division
  • Organized Crime and Vice Division
  • Juvenile Services Unit

In one of their most recent cases, detectives were able to piece together clues found at a crime scene with witness testimony to charge a suspect with murder. Homicide investigators determined that the suspect shot the victim in his car after an argument near the Riverside public housing projects.
