Her husband, Gerald Weintraub, 82, and the other driver, Serap Sezer, 52, of Deer Park, suffered minor injuries and were treated at a hospital and released, police said.

Detectives said the 2 p.m. crash occurred as Gerald Weintraub tried to avoid striking an ambulance that was turning into a driveway as he drove eastbound in a 2003 Honda on Jericho Turnpike near the intersection with Wiltshire Drive.

The Weintraubs’ car was struck by a westbound 2013 BMW driven by Sezer after Weintraub swerved into oncoming traffic, police said.

Both vehicles were impounded for a safety check and police are asking anyone with information to call the Second Squad detectives at 631-854-8252.
