According to WNEP-TV in Scranton, Pennsylvania State Police said the shooter was 24-year-old Randy Stair of Dallas.

The shootings occurred at the Weis store on Hunter Highway in Wyoming County, which was closed at the time.

WNEP reported that investigators indicated Stair had been working at the business since 11 p.m. Wednesday. Less than two hours later, he apparently pulled two pistol grip shotguns from a duffel bag.

Police said Stair killed two men and a woman before firing more shots throughout the store. He then is said to have shot himself in the head.

According to WNEP, the dead co-workers were identified as 63-year-old Terry Sterling of South Montrose; 47-year-old Brian Hayes of Springville; and 25-year-old Victoria Brong of Factoryville.

Investigators say one person who had been in the store at the time was able to escape and call 911. Police then entered the business and found the four bodies.
