WHITE PLAINS, N.Y. (CBSNewYork/AP) — A Westchester County man has pleaded guilty in connection with a wrong-way crash on Interstate 684 that left a woman dead.

Zachary Tokson of Armonk has pleaded guilty to manslaughter and aggravated vehicular homicide, according to Acting Westchester County District Attorney James A. McCarty.

Elena Lopez, 64, of Mount Kisco was killed in the collision in Bedford in the December 2015 crash.

Lopez was driving southbound on I-684 when a driver exited a rest area in Bedford going the wrong way and headed northbound into the southbound lanes, according to police. The two cars collided head-on, cops said.

Tokson had gone wrong way out of the rest stop after pulling over to take a nap.

Authorities said he had been at a bar hours earlier. A search of his vehicle revealed a closed empty whiskey bottle and mixed alcohol in a closed soda bottle.

Tokson and his passenger were treated at Westchester Medical Center for minor injuries. The passenger, a woman, suffered broken ribs, a dislocated femur and damage to her liver and spleen.

A third vehicle heading southbound was sideswiped by Tokson’s car. The three passengers in that car were not injured.
