LOS ANGELES (Reuters) - A former sanitation worker who became known as the "Grim Sleeper" was sentenced to death on Wednesday for murdering nine women and a teenage girl as he preyed on prostitutes and drug addicts in a Los Angeles crime spree dating back 30 years.
Los Angeles County Superior Court Judge Kathleen Kennedy handed down the death sentence recommended in June for Lonnie David Franklin Jr., 63, by a jury. A month earlier, the panel had convicted him on 10 counts of first-degree murder and one count of attempted murder.
"I can’t think of anyone in all my years that has committed the kind of monstrous and the number of monstrous crimes that you have," Kennedy told the serial killer.
Franklin, who is suspected in other unsolved slayings, showed no emotion as the sentence was imposed and did not formally address the court.
Franklin was found guilty of shooting seven women to death from August 1985 to September 1988, then strangling a 15-year-old girl, and strangling or shooting two other women in a second round of killings between March 2002 and January 2007.
The killer was dubbed the "Grim Sleeper" because he seemed to have taken a 13-year break between the two spates of murders.
Franklin also was found guilty of attacking an 11th victim, who survived being shot, raped, pushed out of a car and left for dead in 1988. She testified against him at trial.
Prosecutors say Franklin stalked the streets of South Los Angeles, preying on prostitutes and drug addicts in a crime spree beginning at the height of a crack cocaine epidemic in the area. His victims' nude or partially clothed bodies were found dumped in alleys and trash bins.
Franklin did not testify at his trial. His attorneys had sought to raise doubts about DNA evidence and suggested another "mystery man" was behind the killings.
Authorities said after Franklin's 2011 indictment that they had evidence tying him to several more unsolved slayings, some of which occurred during the presumed lapse in killings. Prosecutors in the penalty phase of the trial were permitted to present testimony about four such cases.
During the sentencing hearing Franklin became agitated when a victim's relative said she had been friendly with him.
"I've never seen you. I've never seen your face. That's a bold-face lie," he said, before being told to calm down by a sheriff's deputy.
