One person was killed and another was injured early Wednesday morning when a man reportedly opened fire outside a Pennsylvania Wawa and then turned the gun on himself.

The incident happened in the store’s parking lot in on Route 22 in Upper Macungie Township, according to Fox 29.

Officers from the Upper Macungie Township Police Department were called to the area of Route 22 for reports of a shooting, according to Lehigh County District Attorney James B. Martin.

A man driving a white Toyota Carolla fired one time at another vehicle driven by a woman around 5 a.m., according to Lehigh County District Attorney James Martin. The woman wasn’t injured and did not even realize her car had been hit until she pulled into the Wawa parking lot.

The suspected shooter pulled into the parking lot and then shot a man who was sitting inside a Jeep. He then shot and killed the driver of a tractor who was pumping gas, Martin said.

The suspect then ran from the Wawa and fatally shot himself in the hand and the chest, according to police. He was not identified by authorities during a Wednesday morning press conference.

“It appears the three shootings were indiscriminate and unrelated,” Martin said.
