The Somerville Police Criminal Investigation Division (CID), is comprised of several individual units including the General Investigations Unit, the Narcotics / Vice Unit, the Gang/Anti-Crime Unit, and the Family Services Unit. All of these units are under the command of the CID Captain.

The General Investigations Unit is responsible for investigating most serious crimes that are reported to the Somerville Police.  Crimes against persons and property are the most common crimes that are investigated by general investigators.  The detectives follow up on most crimes where the suspect is not immediately known or arrested.  These detectives specialize in interviewing victims/witnesses, controlling crime scenes, recovering evidence, apprehending suspects and preparing major cases for prosecution. This unit also functions pro-actively to deter criminal activity by utilizing data from the crime analyst which identify crime trends to predict future criminal events. In additional to investigating traditional crimes, CID has specialized detectives assigned to bank robberies, juvenile crimes, computer crimes, and fugitive arrest warrant apprehension. CID detectives work closely with other local police and State Police departments and Federal Agencies including the FBI and the Drug Enforcement Administration.  Two Somerville detectives are assigned to these Federal Task Forces. 

The Narcotics / Vice Control Unit, under the direction of a supervising Sergeant, is responsible for investigating violations of the controlled substance laws.  This unit develops information from citizens and informants, conducts surveillance of suspects, arrests violators and conducts numerous searches when authorized by warrants issued by the Court.  In addition to arresting violators, this unit initiates forfeiture proceedings to seize vehicles and other property used by drug dealers to conduct their illegal business.  The Narcotics Unit works closely with specially trained Police K-9 Units from Somerville and other communities to find drugs hidden in vehicles and buildings.

The Gang/Anti-Crime Unit is responsible for gathering intelligence and monitoring known or suspected gang members or gang related activity.  Even though Somerville does not have a gang presence like many other communities in the Boston area, the Gang / Anti-Crime unit is constantly gathering information and monitoring youth activity to prevent gang related issues.  The Gang / Anti-Crime Unit is supervised by a Sergeant and works closely with the Juvenile officer and the Neighborhood Police Officers to identify at risk youth and attempt to correct their behavior before it becomes criminal.  In their anti-crime role, the Gang / Anti-Crime Unit works with the crime analyst to identify hot spots for crime and to interrupt crimes in progress. 

The Family Services Unit is responsible for investigating crimes against families, including domestic violence follow-up, sexual assaults and child abuse.  This unit is responsible for managing all restraining orders that are in effect in Somerville.  A part time civilian victim advocate is also assigned to this unit.  She works with victims of family violence to obtain needed services.  The FSU also is responsible for registration of convicted sex offenders who live or work in Somerville.   Detectives from the FSU work closely with the District Attorney’s office to prepare family violence cases for prosecution.  This FSU also investigates civil rights violations.
