Jurors have reached a verdict in the trial of a Los Angeles man charged in the "Grim Sleeper" serial killings that targeted vulnerable young black women over two decades.

Lonnie Franklin Jr. could face the death penalty if convicted Thursday in the 10 slayings after a two-month trial in Los Angeles County Superior Court. The verdict was set to be announced at 1:30 p.m. PDT.

The 10 victims, including a 15-year-old girl, were fatally shot or strangled and dumped in South Los Angeles during the crack cocaine epidemic. Some were prostitutes and most had cocaine in their systems.

The killer was dubbed the "Grim Sleeper" because of an apparent 14-year gap after one woman survived.

A defense lawyer claimed a "mystery man" was the killer, though the prosecutor said that theory was fabricated.
