A former West Valley City police officer will appeal a ruling that tossed out key parts of a federal lawsuit claiming he was wrongly scapegoated for problems in his department after he fatally shot a woman during a drug investigation.

Shaun Cowley has filed notice that he wants an appeals court to reconsider his claims against the prosecutor who charged him with manslaughter in connection with the shooting. The case was later tossed out.

Salt Lake County District Attorney Sim Gill said defamatory things about his role in the death of 21-year-old Danielle Willard that contributed to the ruin of his reputation and loss of his job, Cowley said in the suit. Gill and the county said he wasn't legally responsible for his termination, and pointed out that Cowley had been reinstated.

U.S. District Judge Bruce Jenkins dismissed several of Cowley's claims because the onetime officer got his job back after an appeal and was given $120,000 in back pay. The portions of the suit that were dismissed marked a victory for West Valley in the long-running feud, but three of his claims against the city are still active.

Cowley's attorney, Daniel Baczynski, said during a July hearing that the reinstatement didn't undo the damage to his client's reputation. The city created hostile working conditions that forced Cowley to resign three days after being reinstated, he said.

Cowley was fired in 2013 after he was charged with in Willard's high-profile death in 2012.

Cowley sued the city and Salt Lake County in February, alleging he was made a scapegoat for larger problems with the department's narcotics squad. It was disbanded after an investigation found officers kept souvenirs from drug busts and mishandled evidence.
