A Wisconsin motorcyclist was killed early yesterday in a crash with a fleeing motorist on the Pennsylvania Turnpike in Butler County, state police said.

The Turnpike's eastbound lanes had to be shut down for about five hours between Cranberry and Butler Valley after the man's motorcycle was struck at about 4:11 a.m.

The Allegheny County medical examiner's office identified the motorcyclist as Keith A. Brown, 46, of Green Bay, Wis.

The driver, Dr. Shiva Lal Acharya, 33, of Chicago, fled on foot from the scene and into heavy woods.

Although searchers used infrared scanners and bloodhounds on the ground, the suspect could not be located until a trooper on foot captured him at about 9 a.m. in the woods about two miles from the crash scene.

The motorcycle had been hauling a small trailer when it was struck by the speeding car.

State police said the pursuit of the suspect began across the border in Ohio when highway patrolmen tried to pull him over for speeding. Trooper Robin Mungo said Dr. Acharya had been clocked by Ohio highway patrol driving at 76 mph in a 65 mph zone.

When the suspect failed to pull over, the Ohio pursuers drove beside him, then pulled behind again, only to have the driver accelerate. At one point, Dr. Acharya was driving as fast as 130 mph, Trooper Mungo said.

The Ohio authorities ended their pursuit at the Pennsylvania line, and they notified troopers here that the suspect was headed this way.

The accident caused the immediate stoppage of eastbound traffic.

Both vehicles had been traveling east on the Turnpike past mile marker 33 near Warrendale when the accident occurred, state police said.

Dozens of commuters and tractor-trailers were stranded between exits until the wreckage was cleared and the road reopened at about 9 a.m., police said.

Dr. Acharya suffered injuries to his leg and a laceration above one of his eyes, either in the accident or while traipsing through the woods, police said. He was taken into custody, and they took him to UPMC Passavant. He was charged with homicide by vehicle, fleeing and eluding and other counts.

Police said he had been on his way to a job interview in Easton, Pa.
