(Portland, OR) -- The longest-serving district attorney in Multnomah County history has died. Mike Schrunk was 80 years old. He joined the DA's office in 1970 and was elected top prosecutor in 1981. Schrunk served a record 32 years in office, retiring in 2012. Schrunk's father, Terry Schrunk, served as Portland Mayor from 1957 to 1973. In 2010, following a series of shootings involving police officers, Schrunk started filing for the release of grand jury transcripts into the shootings, a move that was opposed by police. Other district attorneys following Schrunk have continued to do the same thing.
