Ex Input:
Sentence 1: (CBS/ AP)  Rock music producer Phil Spector was convicted Monday of second-degree murder in the shooting death of actress Lana Clarkson at his mansion six years ago. A Superior Court jury returned the verdict after an estimated 29 to 30 hours of deliberations. The jury had the option of choosing involuntary manslaughter, but did not do so. Spector had no obvious reaction. His attorney argued that he should remain free on bail pending the May 29 sentencing but Judge Larry Paul Fidler accepted the prosecution's argument that he be remanded to jail immediately. Sentence 2: Lana Clarkson and Phil Spector were engaged.
