EAU CLAIRE — A decision is likely weeks away on whether criminal charges will be filed in the death of a 20-year-old man Tuesday while riding an all-terrain vehicle in the borough, state police said.

An accident reconstruction investigation and other evidence must be reviewed before police will turn over their findings to the Butler County District Attorney, said Sgt. Rachel Graham.

However, Graham indicated that the 14-year-old boy who was driving the ATV would face at the minimum summary traffic violations, including illegally riding the vehicle on a road.

State law excludes ATVs from use of public roads unless designated by the state or municipality.

Graham said there are no public roads in the county designated for ATV use.

The boy, who police have not identified due to his age, lost control of the four-wheel Yamaha Blaster about 1:10 p.m. Tuesday on Garner Road at South Washington Street and collided with a tractor-trailer.

The teen and his passenger, Shane Scott, both of Eau Claire, were thrown from the ATV. Neither rider was wearing a helmet, police said. State law requires that operators and passengers on ATVs must wear helmets.

Scott was taken to Butler Memorial Hospital where he was pronounced dead at 2:42 p.m. of severe injuries.

The boy suffered minor cuts.

One of Scott’s brothers, Dave Scott Jr. of Petrolia, said Shane Scott was about to start at a new job the day after the accident.

“He was all excited about it,” Scott said.

He said his brother, who was an experienced ATV operator, was friends with the 14-year-old boy who was driving the ATV when the crash occurred.

“They were just having a little fun and an accident happened,” Scott said.
