The criminal investigation division of the West Manchester Township Police Department consists of 1 detective sergeant who supervises 3 additional detectives. They are responsible for collecting information to solve crimes by examining crime scenes, talking to witnesses and informants, collecting physical evidence, or searching records in databases. This enables them to make arrests and present cases in court.
A detective position is achieved by successfully completing a promotional process, including written and oral exams, after an officer completes a minimum number of years as a patrol officer. Detectives then receive specialized training in various areas of criminal investigation including; advanced interview and interrogation, fingerprint collection and examination, DNA collection, and cell phone technology.
The criminal investigation division works closely with the patrol division, who normally is first on the scene. The detectives work varying hours and are also required to be available 24 hours a day throughout the year. A detective may assume investigations which are extensive in scope, geography, or time. The types of crimes that our detectives investigate include: homicide, robbery, burglary, auto theft, missing persons, juvenile crime, fraud, narcotics, vice, criminal intelligence, aggravated assault, sexual assault, computer crime, domestic violence, and arson, among others.
