LAS VEGAS (AP) – A jury has found a former California police officer guilty of sexually assaulting a teenager.

Shawn Shelton, 40, of Moorpark, Calif., faces a potential life sentence as a result of the jury verdict, reached Friday after about two hours of deliberations.

Shelton was found guilty of first-degree kidnapping and sexual assault on a minor for taking the boy on May 21 from a bus stop outside a Las Vegas mall and sexually assaulting him.

Shelton also was found guilty of battery with intent to commit sexual assault on a minor and use of a minor in the production of pornography, after the boy testified that Shelton slammed his head against his skateboard and took Polaroid pictures of him forcing himself on the boy.

“His testimony alone is enough to find the defendant guilty,” prosecutor Joshua Tomsheck said.

Defense attorney Carmine Colucci said an appeal is planned.

“There were some counts I thought we had a real strong chance of getting a verdict in our favor,” he said.

The jury did acquit Shelton of a robbery charge.

The teenager, now 15, took the stand Wednesday and identified Shelton as the man who flashed a badge to convince him to get into a Hummer SUV.

The man told the boy he was investigating a homicide, handcuffed him, drove him to a desert location and placed him in the back seat of the SUV. The teenager testified Shelton forced him to perform oral sex.

Colucci tried to dismiss most of those charges, saying prosecutors did not have the evidence to prove them.

Chief Deputy District Attorney Mary Kay Holthus told jurors earlier in the week that authorities later matched DNA evidence from the boy’s shirt to Shelton, who prosecutors have previously said knew he had the HIV virus.

The teen has not tested positive for the virus.

Shelton was a Los Angeles County sheriff’s deputy for five years before becoming a Manhattan Beach police officer in 1994, authorities said. He was promoted to sergeant in 1999 before taking an extended medical leave and then retiring from the force.
