Rock music producer Phil Spector was convicted Monday of second-degree murder in the shooting death of a film actress at his mansion six years ago. A Superior Court jury returned the verdict after about 30 hours of deliberations. The jury had the option of choosing involuntary manslaughter, but did not do so. The panel also found Spector guilty of using a firearm in committing a crime. Spector exhibited no reaction to the verdict. His attorney argued that he should remain free on bail pending the May 29 sentencing, but Judge Larry Paul Fidler remanded him to jail immediately. Second-degree murder carries a penalty of 15 years to life in prison, and the firearm charge carries up to three years in prison. The 40-year-old Lana Clarkson, star of the 1985 cult film "Barbarian Queen," died of a gunshot fired in her mouth as she sat in the foyer of Spector's mansion in 2003. She met Spector only hours earlier at her job as a nightclub hostess.
