YATES COUNTY, N.Y. -- A Penn Yan man has pleaded guilty to causing a crash that killed six Amish farmers in Yates County last July.

As part of a plea deal, Steven Eldridge, 42, pleaded guilty Wednesday to two counts of aggravated vehicular homicide, aggravated vehicular assault, and driving while intoxicated.

Eldridge told the court he had taken cocaine and prescription drugs the day of the crash, and when he came upon a slow moving tractor on Preemption Road in the Town of Benton, he ignored the fact that he was on a sharp curve and swung around to pass the tractor.

Eldridge collided with an oncoming van carrying more than a dozen Amish farmers from Steuben County, which then careened into the tractor.

Six people in the van were killed, and a number of others seriously injured.

As part of his plea deal, Eldridge waived his right to an appeal. He faces up to 24 years in prison when he is sentenced next month.
