The Major Crimes Bureau prosecutes felony offenses involving violent crimes such as first degree murder (including all death penalty cases) and other homicides, aggravated assaults involving serious physical injuries and the use of deadly weapons and dangerous instruments, drive-by shootings, gang-related crimes, serious domestic-violence related felony offenses such as aggravated assaults with strangulation, and sexual crimes such as sexual assault, sexual conduct with a minor, child molestation, sexual exploitation (child pornography), and child sex trafficking.

Major Crimes Bureau attorneys are skilled prosecutors with at least 5 years of felony-level prosecuting experience and extensive specialized training.  Major Crimes Bureau attorneys meet frequently with the County Attorney, Chief Deputy, and other senior prosecutors as part of incident review panels to evaluate homicides and other complex cases on issues such as charging decisions, death penalty notice filings, plea agreements, and circumstances surrounding officer-involved shootings.  The Major Crimes Bureau works with all local, state, and federal law enforcement agencies in Pinal County.
