The 18-year-old Slippery Rock University student who died in the Friday, Feb. 6, pileup along Interstate 79 in Jackson Township was likely trying to slow down in reaction to the multiple crashes ahead of him when his vehicle slid into a trailer, according to new information released late Sunday night by state police.

Pittsburgh native Evan M. Gingo was killed in the crash while driving north in a Subaru Impreza, police said. The crash occurred at 10:28 a.m. near mile marker 84.5 in Jackson Township.

Gingo’s vehicle collided with a trailer attached to the back of a Chevrolet Silverado, which was stopped on the road due to the previous crashes. Police said his Impreza lost traction on the icy road and slid into the attached trailer.

The Chevrolet Silverado was driven by Jeremy J. Watson, 49, of Pittsburgh. Police said Gingo was wearing a seat belt and his air bags deployed. Watson was uninjured.

The pileup involved at least 25 vehicles and left another 20 disabled motorists, police said. I-79 was closed for several hours between the Zelienople and Evans City exits and other areas had speed limits lowered to 45 mph.

Police said Friday nine people were taken from the scene of the crashes to area hospitals for injuries, but not all nine were detailed in the information released Sunday.

In information released Sunday night, police detailed two other incidents related to the pileup in Jackson Township — one before and one after the crash involving Gingo.

Minutes prior to the fatal collision, a crash involving four vehicles was reported at the same mile marker. That crash happened in reaction to yet another crash, police said.

According to police, a Kenworth T880 traveling north on the icy road moved abruptly to avoid a prior crash. This prompted the driver of a Dodge Journey to pull off the side of the road and exit his vehicle in an attempt to warn oncoming traffic, police said.

That’s when the driver of a Freightliner Cascadia traveling northbound attempted to avoid striking the Kenworth and encountered ice, according to police. Its trailer fishtailed and struck both the Kenworth’s bumper and the Dodge Journey’s driver’s side door.

A Jeep Gladiator, driven by a West Virginia couple, then slid into the Freightliner, police said.

The Kenworth T880 was driven by Lisa McAllister, 53, of Ellwood City; the Dodge Journey was driven by Casey Steele, 34, of Edinburg; the Freightliner was driven by Stanley Barnhisel, 60, of Spring Hill, Fla.; and the Jeep Gladiator was driven by Joseph Lathrop, 67, of Fairmont, W.Va., the report detailed.

Lathrop and his passenger, Debra Lathrop, 66, were both taken to Allegheny General Hospital with suspected minor injuries. The others involved were not taken to hospitals.

No injuries were reported in the other crash, which was detailed in the Sunday night report from state police.

In that crash, police said the driver of a Nissan Altima approached stopped traffic at a high speed prompting a crash.

The Nissan Altima struck a Ford Escape, pushing it from the right to the left northbound lane. There, the Ford Escape was struck by a Kenworth, police said.

Crystal Weimer, 44, of Baden, was the driver of the Ford Escape, and Paul Singer, 29, of Champion was the driver of the Kenworth.

According to police, the driver of the Nissan Altima, Andrew Borsch, 44, of Munhall, would face a summary charge of driving at an unsafe speed.
