MINEOLA, N.Y. — A New York man has been sentenced to 25 years to life for the 1986 shooting of a businessman found dead in his Long Island driveway.

Lewis Slaughter is already serving 25 years to life in an unrelated 1986 killing. He was sentenced Thursday for the murder of plumbing store owner Samuel Quentzel in Woodmere. The killing apparently was the result of a botched robbery.

Prosecutors matched DNA from one of three suspects involved in the shooting to a cigarette butt found in the getaway vehicle.

Slaughter, who’s now 61, is currently in prison for the October 1986 murder of a woman while fleeing a Queens robbery.

A second suspect has pleaded guilty to manslaughter in Quentzel’s killing and is awaiting sentencing. A third suspect was killed in an unrelated incident.
