A Dorchester man was killed and a Quincy woman seriously injured in a motorcycle accident in Quincy on Saturday.
According to police, a witness driving down Ricciuti Drive at 9:58 p.m. heard a loud noise, and saw a motorcycle traveling at approximately 60 miles per hour down the street. The motorcycle soon disappeared out of sight, but within seconds the witness came upon the crash. The witness called 911.
Police said the man, Shawn Morris, 32, of Dorchester, sustained serious head and chest injuries. He was taken to Boston Medical Center and died from his injuries the next day.
A woman passenger, Nicole Mahone, 30, of Quincy sustained serious injuries to her hip and leg, police said. She was taken to Boston Medical Center, where her condition was not immediately known.
Police said speed was most likely a factor in the accident. The speed limit on the street is less than 30 miles per hour.
The accident is under investigation by the Quincy Police Accident Reconstruction Team; however, a preliminary investigation shows that the motorcycle most likely hit a curb near a cut-in to several Quincy condos, knocking off both riders.
The accident occurred around the same area as a fatal motorcycle accident last September involving a man and his son.
Despite the two similar fatal motorcycle accidents on the street, Quincy police Captain John Dougan said police did not consider the area near the Granite Links Golf Club to be dangerous.
“Accidents occurred as a result of operator error or negligence,” Dougan said.
