It’s a cold case no more. Nassau County law enforcement officials believe they’ve solved a 23-year-old robbery and murder of a Woodmere man.

Samuel Quentzel, 54, was shot to death after pulling into his driveway on Sept. 4, 1986 at around 7:10 p.m. Two men jumped out of a tan van and immediately came up the side of Quentzel’s white Oldsmobile and shot him in the left side.

Quentzel was a millionaire who owned a plumbing business in Brooklyn. His checkbook was taken from his vehicle during the shooting, police said.

The murder suspects have been identified as 48-year-old Roger Williams, and 60-year-old Louis Slaughter both from Brooklyn. They’ve been described by law enforcement officials as career criminals.

Changes in DNA profiling allowed authotities to trace cigarette butts found in the van to Williams and Slaughter.

The alleged triggerman — 33-year-old Clifton Waters — was accidentally shot to death four months after the Quentzel murder.
