A Lancaster, CA, man was sentenced Monday to life in prison without the possibility of parole for the execution-style slaying of a Los Angeles County sheriff's sergeant five years ago.
Trenton Trevon Lovell, 31, had two prior convictions and was on parole at the time of the slaying of Sgt. Steve Owen , 53, who was shot five times on Oct. 5, 2016, after responding to a burglary call in Lancaster.
