Two separate crashes in less than 48 hours at opposite ends of County Line Road in northern Mercer County have claimed the lives of three young men.

Pennsylvania State Police at Mercer and the Mercer County Coroner’s Office are investigating the separate crashes along County Line Road, which borders Crawford and Mercer counties.

Justin Ryan Opatrny, 21, of Cochranton, was killed in a single-vehicle crash on County Line Road near Route 173 in French Creek Township around 3:15 a.m. Friday, state police said. The area, toward the eastern end of the road, is about 3 miles south of the Crawford County community of Cochranton.

The second crash was a double fatality early Sunday involving two dirt-bike-style motorcycles that collided head-on, Robert Snyder, chief deputy coroner of Mercer County, told the Meadville Tribune. That crash happened in the 1200 block of County Line Road in Mercer County’s Salem Township, he said.

Authorities have not released the identities of the two men, though Snyder said both victims were age 22.

One dirt bike was traveling east on County Line Road when it collided head-on with westbound one shortly after 1:30 a.m. Sunday, Snyder said. The crash site is west of Methodist Road in Salem Township and about 3 miles south of the Crawford County village of Atlantic.

Neither motorcyclist was wearing a helmet, and neither motorcycle had lights, Snyder said, adding that the area also didn’t have any street lights.

A third, eastbound dirt bike then crashed into the other two motorcycles, throwing its driver off the bike, Snyder said. The third motorcyclist also wasn’t wearing a helmet, and that bike didn’t have lights, Snyder said.

The third motorcyclist was taken to Meadville Medical Center for treatment, but later transferred to UPMC Hamot hospital in Erie, Snyder said.

Additional information about the crashes is expected to be released later today.
