The Aliquippa police officer charged in a shooting last week in Pittsburgh that wounded an Allegheny County Jail corrections officer has turned himself in to authorities, according to a statement from Pittsburgh police. 24-year-old Josh Gonzalez of Brentwood who said he had been on the Aliquippa force for five months, turned himself in around 10:30 this morning after he was charged Saturday by city police with one count of aggravated assault in the shooting of Kevin Miller, a corrections officer for nine years at the county jail. The charges stemmed from an incident that happened Thursday.
