A 20-year-old Manhasset man was charged Friday with vehicular manslaughter after a late-night crash on the Long Island Expressway in Woodbury that killed a passenger in his BMW, Nassau police said.

Jonnathan Santos was impaired by marijuana and alcohol at 11:48 p.m. Thursday when he drove east at a “high rate” of speed and struck two other vehicles near Exit 44 at the Seaford-Oyster Bay Expressway interchange, according to the complaint filed against him.

His backseat passenger was ejected after the BMW hit the first vehicle and spun into a guardrail on the right shoulder, court documents said. The BMW continued spinning out of control and struck a Toyota pickup truck, according to the complaint.

The passenger was pronounced dead at the scene. The victim’s name was withheld pending notification of next of kin, police said.

Santos was arraigned Friday in First District Court in Hempstead on the vehicular manslaughter charge as well as a charge of driving while ability impaired. Bail was set at $50,000 bond or $25,000 cash, prosecutors said.

Santos’ attorney and family could not be reached for comment Friday night.

All eastbound lanes reopened by about 6 a.m. Friday, police said. Officers with flashlights could be seen Friday morning searching the shoulder, embankment and roadway for evidence.

Additional details about the crash were not available Friday night, including Santos’ speed and whether others involved in the crash suffered injuries.

Detectives said they were continuing the investigation.
