SPRINGFIELD — A ranking member of the Hells Angels motorcycle club was convicted Friday of killing three Pittsfield men who prosecutors said were slain so they could not testify against him.
A Hampden Superior Court jury found Adam Lee Hall guilty of three counts of murder and other charges including kidnapping and intimidating a witness.
Hall hung his head as the verdicts were read, and members of the victims’ families and police embraced, the Berkshire Eagle reported.
Hall, 36, of Peru, Mass., and two other men were charged with fatally shooting David Glasser, Edward Frampton, and Robert Chadwell in August 2011 and disposing of their bodies in Becket. Hall was the first to face trial.
‘‘I’m just glad this is over; it’s been a long, long, long two years,’’ said Chadwell’s sister, Carol Chadwell Smith.
Prosecutors said Hall had previously assaulted Glasser and wanted him dead so he could not testify. They said Frampton and Chadwell were killed because they were with Glasser and would have been witnesses.
Hall’s defense lawyer, Alan Black, said there was no physical evidence linking Hall to the killings. He did not immediately comment after the verdict.
‘‘There was an incredible amount of work put in by a great number of people who did an excellent job,’’ District Attorney David Capeless told The Republican of Springfield after the verdicts. ‘‘They were tireless, tireless in trying to determine not just whether or not Adam Hall did it and also to determine if it was possible that anyone else had done it. I think the public needs to understand this was an incredibly thorough investigation.’’
Two of Hall’s codefendants testified he masterminded the killings. Another man charged as an accessory said he helped dispose of the bodies because he was afraid of Hall. They are being tried separately later this year.
Hall is to be sentenced Monday. His trial was moved to Springfield because of extensive news coverage of the case.
