State police at Rockview have released additional information about a vehicle that crashed and caught fire late Sunday on Interstate 80 in Boggs Township.

Police said Louis Sellman, 73, of Coraopolis, was driving a pickup truck hauling a large trailer that was carrying ammunition and gunpowder. Sellman was passing another vehicle when he lost control of the trailer, which struck a guide rail on the left side of the highway.

Police said Sellman then slammed the brakes, causing his vehicle to jackknife and hit a bridge on the right side of the road.

After the crash, the trailer rolled onto its side and burst into flames. The ammunition and gunpowder caused a large fire, police said.

Firefighters and a neighbor at the scene reported ammunition was exploding due to the heat.

Sellman and two passengers, Daniel Ogershok, 54, of Russellton, and Joseph Brentzel, 64, of Trafford, escaped with only minor injuries.

A Department of Transportation spokesperson said Wednesday that a bridge engineer inspected the bridge after the accident and found no damage. A stretch on westbound I-80 remained closed for several hours while emergency crews were on scene, police said.
