SHENANGO TWP., Mercer Co., Pa. - We're learning more details about a fatal crash that closed the westbound lanes of I-80 in Mercer County on Wednesday, March 18.

A crash report from Mercer County PSP reveals the crash happened just after 9:30 a.m. on I-80 in Shenango Township just east of Bethel-Wilmington Road.

Police say a 2024 Ram 3500 pickup truck driven by 26-year-old Carlos Valdivia-Perez of Cliffside Park, New Jersey, rear-ended a 2018 Ford Focus driven by an 81-year-old man from Clarion, Pennsylvania.

From there, the Ford crashed into the back of a semi truck driven by 50-year-old Wilner Dompierre of White Plains, New York, and went partially under the semi's trailer and got stuck to the semi.

According to the crash report, Valdivia-Perez was cited for following too closely.

Valdivia-Perez and Dompierre were both taken to the hospital with possible injuries, but the 81-year-old Ford driver was pronounced dead at the scene. Mercer County Coroner John Libonati told 21 News the man suffered blunt force trauma to the head and chest.

Police have not released the man's identity at this time.

A dispatcher with PSP told 21 News the crash occurred in a construction zone.

The westbound lanes in the area of the crash were closed for several hours afterwards, and drivers were being rerouted into the eastbound lanes. The westbound lanes have since reopened.
