A senior member of a Massachusetts local Hells Angels chapter, Adam Hall, was charged with the murders of three men, including a key witness scheduled to testify against him, MSNBC is reporting. The reputed sergeant-at-arms at the Berkshire Hells Angels motorcycle club was charged with three counts of murder, kidnapping and intimidation of a witness.

Berkshire County District Attorney David Capeless announced the charges after a two-week search for three Pittsfield, Massachusetts men who had disappeared under suspicious circumstances. Their bodies were discovered in the western part of the state. But he didn’t disclose where authorities found the bodies of the victims, including David Glasser, Edward Frampton and Robert Chadwell.

Capeless also didn’t confirm how prosecutors believe the three men, who disappeared on August 28, died. But NBC station WNYT reported that detectives had been spotted searching the grounds of the Pittsfield State Forest.

Glasser was scheduled to testify against Hall at a trial on assault, robbery and kidnapping charges. The trial was scheduled to begin on September 19. “This had to do with Glasser’s being a witness in a pending criminal case,” Capeless told WNYT. He added that authorities believe Frampton, Glasser’s roommate, and Chadwell, a friend of the two men, were at the wrong place at the wrong time.

Authorities will be examining the site where the three victims were found for evidence. Hall is scheduled to be arraigned today in Central Berkshire District Court in Pittsfield.
