Killer driver was fleeing

The driver in the Long Island crash that left him and four others dead was trying to outrun cops at the time — and had turned off his headlights seconds before the collision, police said.

Justin Mendez, 22, had “a quantity of marijuana” in his car when he slammed into the Uber vehicle, killing the four people inside and himself, Quogue Police Chief Chris Isola said at a press conference Tuesday.

“The officer spots Mendez 1,000 feet inside the village of Quogue, heading west,” Isola said. “There’s a sharp turn. The officer had a very brief view of the vehicle. He very quickly loses sight and never catches up.”

He said the cop turned on his overhead lights “several seconds” before the deadly crash, but added, “There was no chase.”

The Saturday-night crash killed Uber driver Farhan Zahid, 32, and three of his passengers — among them brothers Michael Farrell, 20, and James Farrell, 25, according to police.

Another passenger in Zahid’s Toyota Prius, Ryan Kiess, 25, was also killed, and Kiess’ girlfriend, Brianna Maglio, 22, is in critical condition at Peconic Bay Medical Center.

Isola said Mendez lost control of his car after hitting a dangerous sharp curve on the roadway, where two people were killed in a 1997 crash.
