PITTSBURGH -- A man is dead after a police-involved shooting and pursuit on Pittsburgh's South Side early Sunday morning.

The Allegheny Couny Medical Examiner's Office identified the man as Nicholas Haniotakis, 33, of the South Side, saying he died from multiple gunshot wounds to the chest and extremities.

Pittsburgh police and a state trooper working on a roving driving under the influence patrol said they observed a white 2000 Oldsmobile Bravada sport utility vehicle traveling south in the wrong lane on 13th and East Carson streets without its headlights on around 1:30 a.m.

According to a Pittsburgh police statement, the SUV reached the intersection, stopped and repeatedly lurched forward, nearly broadsiding the police car.

"When officers activated their emergency lights, the driver put the vehicle in reverse and backed down 13th Street at a high rate of speed," Pittsburgh Police Chief Nate Harper said.

The SUV ultimately crashed into a parked car at Wharton and 22nd streets, where, police said, Haniotakis refused to comply with the officers' orders and the officers fired an unknown number of shots into the SUV. Police said Haniotakis backed up again before sharply turning the SUV toward an officer, at which time several more shots were fired.

Haniotakis drove off and crashed into a telephone pole and parked cars at Sarah and 22nd streets.

"There was a race of an engine, and that's when I looked at it. Then, the white truck came racing up and then smashed into the pole," said James Lippencott, a witness.

Paramedics transported Haniotakis to UPMC Mercy, where he was pronounced dead shortly after 2 a.m.

"They was asking him a couple times, 'Get out of the car, step out of the car.' They wouldn't go towards the car. They stayed back a little bit because they probably thought he had a gun," said Richard Bruno, a witness.

"With the whole volume of safety vehicles, we didn't know what exactly was happening. So, we were just really curious," said Taite Hopwood, a witness.

Haniotakis had a similar run-in with the law in 2005 when he was involved in a chase in Mount Oliver after hitting a police officer with his car, records indicate. The car crashed into a cement barrier, and Haniotakis ran off.

Police arrested Haniotakis, who pleaded guilty to a charge of aggravated assault and was sentenced to 11½ to 23 months in jail.

Prosecutors, Pittsburgh police and state police continued to investigate Sunday.

No one answered the door at Haniotakis' listed South Side Slopes residence, and neighbors declined to comment.

Channel 4 Action News' Amber Nicotra reported the Allegheny County Medical Examiner's office said Haniotakis died from multiple gunshot wounds.

The shooting remains under investigation by both the Pittsburgh police department and the District Attorney's office.
