Connecticut ? A motorcyclist gunned down on Interstate 95 Sunday was a leader in the Connecticut chapter of the Hells Angels who had served time in federal prison on drug charges, police said.

Roger Mariani was one of 37 Hells Angels and associates from Connecticut arrested in the mid-1980s as part of a nationwide crackdown that resulted in 125 arrests and the seizure of $2 million worth of drugs. He was released from prison in 1995, according to the U.S. Bureau of Prisons.

Mariani, 61, of Stratford, was killed and motorcyclist Paul Carrol, 37, of Bridgeport, was wounded Sunday afternoon when someone opened fire on I-95 in West Haven.

Mariani was shot in the chest but managed to pull off to the side of the road. The medical examiner’s office on Monday ruled his death a homicide.

State police were still looking Monday for a GMC sport-utility vehicle with Florida plates. They believe four men were inside. They also were looking into the possibility that the shootings occurred during an altercation between the motorcyclists, who were riding in a group, and the people in the SUV.
