LOS ANGELES — A man suspected of shooting a Los Angeles County sheriff’s sergeant and pumping four more bullets into his body as he lay on the ground was charged Friday with murder and several other felonies.

Trenton Trevon Lovell could face the death penalty or life in prison if convicted. Prosecutors had not yet decided which penalty they would seek.

Lovell, 27, was jailed without bail and it was unclear whether he had a lawyer.

He was arrested on Wednesday after Sgt. Steven Owen, 53, was gunned down while responding to a burglary report behind an apartment building in Lancaster, a desert town north of Los Angeles.

Lovell, a paroled robber with a dozen arrests on his record, shot Owen after the sergeant arrived.

Then he stood over Owen and fired four more times in a “calculated execution,” Sheriff Jim McDonnell told reporters.

Lovell pointed a gun at another sheriff’s deputy, who shot him in the shoulder.

The suspect then stole Owen’s patrol car, rammed another police vehicle with it and held two teenagers hostage at knifepoint in a building before he was captured, authorities said.

He was charged with murder with special circumstance allegations that make him eligible for the death penalty: killing a peace officer and killing to avoid arrest.

He was also charged with attempted murder for using the patrol car as a deadly weapon, and with two counts each of robbery and false imprisonment for holding the teenagers hostage.

Owen was a decorated 29-year veteran of the Sheriff’s Department.

Lancaster Mayor R. Rex Parris said Friday that he will ask the City Council to rename a community park in Owen’s name.
