Major Investigations

Created in 2011, the Major Investigations Unit (MIU) investigates and prosecutes violent repeat offenders and violent criminal organizations in Baltimore. MIU is staffed by nine Assistant State’s Attorneys (ASA) and a Division Chief.  The MIU also includes three ASAs detailed to the USAO as Special Assistant United States Attorneys to investigate and prosecute narcotics and firearms cases. Federal laws often carry longer sentences than state laws; the ASAs cross-designated to the USAO enable the USAO to accept more referrals from our office for prosecution in federal court that could result in longer sentences for convicted, violent offenders.

The MIU works closely with the Baltimore Police Department (BPD), the United States Attorney’s Office (USAO), and other local, state and federal law enforcement partners to investigate and build strong cases against violent repeat offenders or violent criminal organizations. The MIU also includes the City Corrections Investigative Unit (CCIU). The CCIU is a collaborative effort between the OSA, the Department of Public Safety and Correctional Services (DPSCS), the BPD and the Maryland State Police to combat corruption in Baltimore’s correctional facilities.
