Both Mitch and his wife, Maggie Cannon Morrissey, were born in Denver and have two children. Mitch is proud to have attended Colorado schools: the University of Denver College of Law, University of Colorado, Boulder, J. K. Mullen High School and Bear Creek Elementary. 

As the chief prosecutor for the Second Judicial District, Mitch is an aggressive prosecutor and an advocate of prevention and intervention initiatives. He makes victims a priority and is dedicated to providing victims a strong voice in the justice system through a number of efforts.

Mitch leads a strong (and award-winning) team of Victim Advocates who work closely with victims of crime. He understands the impact of crime on people and supports the work of programs like the Victim Services Network. This important work coordinates different services for victims, especially those in under-served areas and communities.

An important tool in solving and prosecuting many crimes is DNA technology. Mitch recognized the potential of DNA science early on and prosecuted the first trial in Denver to utilize DNA. His DNA Resource Section on his web site has become an international resource for other prosecutors.

 Mitch serves on the board of the National Forensic Science Technology Center, as well as the board for Denver Crime Stoppers. He is a member of the Advisory Council for National Law Enforcement and Corrections Technology Council for the Rocky Mountain Region and has served on the board of the Denver Sexual Assault Interagency Council.
