On Saturday night, the sergeant was investigating a ShotSpotter call and homicide in southeast Fresno when authorities say 40-year-old Andy Morales shot the sergeant several times.
Morales was killed in a gun battle with the sergeant and two other officers.
Police say they later discovered Morales used the same gun to kill a longtime friend earlier that night.
The department thanked the community for the support of both the sergeant and the department as a whole.
