Saturday's shooting was not the first for Mosher, who in April 2006 was one of two officers who shot and killed a suspect in a car.At a coroner's inquest, officers Mosher and John Jessie Wiggins testified they feared for Wiggins' life when they opened fire on Aaron Jones at the Sunset Breeze apartments in the southwest valley. Both officers fired after Jones, a suspect in a home burglary, backed up his car and hit Wiggins in an attempt to escape.
