It is the primary responsibility of the Prosecuting Attorney to prosecute persons charged with felony offenses that occur anywhere within Montgomery County. Through the Criminal Division, the Prosecutor's Office annually reviews over 5,000 cases submitted for filing as felonies by the various law enforcement agencies. The Criminal Division consists of four trial teams; an intake section, which handles all preliminary hearing and grand jury matters; as well as a Violent Crimes Bureau.

The Violent Crimes Bureau was established in January, 1993., to target and fast track the most serious and dangerous offenders. Due to the serious nature and circumstances of felony cases, and the obvious importance and impact crime has on all citizens, the Criminal Division is the most visible division of the office.
