Two men were killed and one was seriously injured in the early hours of Tuesday morning, after police say one of them lost control of his car and slammed into a tree.

The Suffolk County Police Department said 26-year-old Hauppauge resident Leland Acampora crashed the Hyundai Sonata at about 4:30 a.m. while heading west on Fort Salonga Road near Makamah Road.

Both he and 26-year-old Commack resident Woody Zalman, who had been sitting in the back seat, were pronounced dead at the scene, police said. However, front seat passenger Paul Weingart, a 26-year-old from East Northport, was in serious condition at Stony Brook University Hospital, after being airlifted there by police helicopter.

Police impounded the Hyundai for a safety check.

Detectives from the SCPD’s 2nd Squad are investigating the single-car crash. Anyone with information is asked to call them at 631-854-8252.
