A three-vehicle crash that sent two people to the hospital Saturday was caused by a driver impaired by drugs, Erie County sheriff’s officials said.

The crash happened at about 10:30 a.m. Saturday at Clinton Street and Eastwood Road in the Town of Marilla.

Sarah Ulrich, 18, of Marilla, was westbound on Clinton, waiting to turn south onto Eastwood Road, when her vehicle was struck from behind by a car driven by Jerry L. Roll, 59, of Cowelsville, officials said.

Accident investigators determined Roll did not brake before colliding with Ulrich’s vehicle. The force of the crash sent Ulrich’s vehicle across the center line, where it was struck by an eastbound pickup, sheriff’s officials said.

The driver of the pickup, James R. Pautler Jr., 28, of Alden was treated at the scene by the Marilla Fire Company and released.

Ulrich and Roll were taken to the Erie County Medical Center, where Ulrich was treated for minor injuries and released.

Roll remained in the hospital with injuries on Saturday.

Investigators, however, accused Roll – who refused a chemical test – of being under the influence of drugs at the time of the crash.

“I don’t want you to know about all the drugs in me,” he allegedly told sheriff’s deputies.

Roll was charged with driving while ability impaired by drugs and was also issued a ticket for following too closely.
