John Pettit (July 13, 1935 – October 30, 2010) was a long-time District Attorney of Washington County, Pennsylvania.[1] He attended Washington High School, the University of Pennsylvania, and The Dickinson School of Law.
He and Judge Paul Pozonsky founded the county's first drug treatment court in 2004.[2] He was criticized for using jailhouse informants during his 24-year-long tenure as district attorney, leading to a murder conviction being overturned. At the time of the 2007 defeat for re-election, losing to Steven Toprani, he was being investigated by the Federal Bureau of Investigation and a grand jury for preferential treatment to friends and political supporters as district attorney. Ultimately, he was never indicted.
