The Detective Squad is comprised of five investigative units; Burglary Unit, Fraud Unit, General Investigations Unit, Property Crimes Unit and Violent Crimes Unit. The units cover two shifts that work from 7:30 am to 11:30 pm. The supervisors assigned to the Detective Squad are:
Det. Lieutenant – currently vacant
Det. Lieutenant Carlo Capano - ccapano@manchesternh.gov
Det. Sergeant Ryan Grant - rgrant@manchesternh.gov
Det. Sergeant Sean Leighton - sleighto@manchesternh.gov
Detectives assigned to each unit investigate specific types of crimes that fall within the unit classification, but often each detective is involved in some capacity investigating all manner of crimes that occur within the city. In the event of a homicide or other serious investigations, any one, and often most, of the detectives assigned to the Detective Squad are involved in the investigation, which includes crime scene investigations.
