Special Investigations Unit
The Special Investigations Unit (SIU) / Gang Suppression Unit (GSU) is comprised of nine officers: A Lieutenant, a Detective Sergeant, five Detectives and two Corporals. One of these Corporals maintains the Police Department's drug-detection canine, "Sonny." There are three additional Investigators assigned to the Special Investigations Unit, who are assigned to three separate area drug enforcement task forces: The Drug Enforcement Administration (DEA) - Milwaukee District Office, the High Intensity Drug Trafficking Area (HIDTA), and the Milwaukee Metropolitan Drug Enforcement Group (MMDEG).
The Special Investigations Unit is responsible for the investigation of vice-related crime including but not limited to offenses surrounding illegal drugs / narcotics, gang-related offenses, weapons, prostitution, gambling, and pharmaceutical diversion. The SIU focuses on these offenses at a local level. The SIU also works in conjunction with other local, state and federal agencies in the Milwaukee area to address these offenses regionally, which directly affect our community.
The Special Investigations Unit relies significantly on cooperation with citizens who are dedicated to ensuring the safety of their neighborhoods. Citizens can provide the Police Department with detailed complaints regarding suspected drug dealers in their community, with the understanding that their identities can remain anonymous or confidential. Investigators assigned to the Special Investigations Unit are committed to an integrated team approach in conducting investigations through the sharing of information and cooperation with other divisions within the department. Investigators incorporate a myriad of investigative techniques while conducting efficient and effective investigations.
