The Yonkers man who killed an off-duty NYPD officer during a botched robbery was sentenced to life in prison without parole Thursday.

Steven Armento, a reputed low-level mob associate, was convicted of murder last month in the shooting of Officer Daniel Enchautegui on Dec. 10, 2005. His co-defendant, former "Sopranos" actor Lillo Brancato, goes on trial next week.

Authorities say Armento and Brancato broke into a Bronx basement apartment to steal prescription drugs after a night of drinking at a Yonkers strip club. Enchautegui, who lived next door, heard glass breaking at the apartment and went out to investigate.

Armento shot the 28-year-old officer with his .357 Magnum, hitting him in the heart. The dying officer fired back, wounding both men.

Brancato has said he didn't know Armento had a gun.
