Witness says speeding car caused fatal motorcycle crash

ANDOVER – A witness said a car sped onto Interstate 93, crossed four lanes of traffic and cut off the motorcycle John and Marie Bushnell of Methuen were riding Saturday afternoon.

Marie, 52, of 46 Capital St., was pronounced dead after the crash. John, who was driving the bike, was airlifted by medical helicopter to Massachusetts General Hospital, where he was listed in critical condition late Saturday night. His condition was unavailable last night.

The deadly crash occurred on the southbound side of I-93 at I-495 just before 2 p.m.

A witness said he told state police about a light green sedan, possibly a four-door Toyota Avalon, with New Hampshire plates that sped onto the highway from the I-495 off-ramp before the crash. The sedan driver was “flying” and cut across four lanes of traffic, creating a blind spot for the motorcycle driver, he said.

The bike then struck at least one of two SUVS, a Jeep Liberty and a GMC Jimmy, that were stopped in the merge lane on I-93 south after they had collided previously.

The witness said he saw the motorcycle crash. “It was awful, absolutely awful. I was in shock. My wife was hysterical,” said the Andover man, who asked not to be identified until charges are filed in the accident.

He said he called the state police barracks in Andover to tell troopers about the speeding light green car. “In my opinion, that car was 100 percent the cause of the accident,” the man said last night.

The drivers of the Jeep Liberty and GMC Jimmy were not injured. Police said Paul Mosca, 65, of Waltham was driving the GMC Jimmy. Mark Thompson, 32, of Salem, N.H., was at the Jeep’s wheel.

No other accident details were released last night.
