PITTSBURGH—Police officers investigating a western Pennsylvania bar shooting fired on three people inside a car that was speeding toward them, killing the driver and wounding two passengers, state police announced Monday.

Troopers from the Ebensburg barracks were investigating the shooting early Monday in Johnstown, about 60 miles east of Pittsburgh, Trooper John Matchik, a spokesman for the barracks told The Associated Press.

Nobody has been charged in connection with either the police shooting or the bar shooting, as both remained under investigation Monday afternoon.

The episode began when a Johnstown police sergeant on patrol heard shots being fired among a group of people outside Edder's Bar at about 12:30 a.m. and followed a car he saw driving away with its passenger door partly open, Matchik said. The car drove a short distance, until it was stopped when another patrol car pulled in front of it, and a man jumped out, Matchik said.

The man who ran away was taken into custody for questioning and the woman driving the car was handcuffed while police tried to determine whether the car was linked to the shots fired outside the bar.

While that was happening, a car driven by 27-year-old Elip Cheatham, of Johnstown, sped toward police and, according to Matchik, ignored officers' commands to stop.

Three Johnstown officers opened fire on the car, which also was carrying two passengers, Matchik said. It was not immediately clear how many shots were fired or how many hit the three people in the car.

Cheatham died of his wounds a short time later at Conemaugh Medical Center in Johnstown, according to the Cambria County coroner's office. One of his passengers was treated and released, and the condition of the third person in the car was not immediately available, Matchik said.

The woman who had been handcuffed in the initial car stop was released after being questioned. Police have yet to identify the man who ran away from her car or say whether he will be charged.

Johnstown police Chief Craig Foust said the state police are investigating both the officer involved shooting and the bar shooting since it appears they are related. As a result, the chief told the AP he could not comment beyond confirming that all three officers involved in the shooting are on paid leave pending the results of the investigation.

State police were not releasing the names of those wounded by police or the officers involved.

Online court records show Cheatham was arrested on charges of receiving stolen property and illegal possession of a handgun in 2005 in Cumberland County. He was convicted on the firearms charge and sentenced to 2 1/2 to 5 years in state prison in 2006. Records also show he was charged with simple assault, disorderly conduct and harassment by the Johnstown police in February 2011, but that a district judge later dismissed the charges.

Cambria County Chief Deputy Coroner Jeff Lees told the Tribune-Democrat of Johnstown (http://bit.ly/OkJYhh) that Cheatham's vehicle was speeding toward the traffic stop when officers opened fire.

"They were detaining suspects in that vehicle when the second car comes down (the street) at a high rate of speed," Lees said.

A woman who answered the phone at the bar said nobody was available to comment, put promised to pass on a request for comment to the owner.
