PITTSFIELD, Mass. — Adam Lee Hall, 38, of Peru was found guilty of three counts of murder after a monthlong trial held in Hampden Superior Court in Springfield.

The jury deliberated for about 17 hours over a four-day period before returning a verdict. He will be sentenced on Monday.

Hall, aka "Leo Mazoli" and a purported Hell's Angel, was accused of kidnapping and killing David Glasser, 44,  Edward Frampton, 58, and Robert Chadwell, 47, with two alleged accomplices. The three Pittsfield men were last seen at a Pittsfield apartment shared by Glasser and Frampton on Aug. 28, 2011. Glasser was set to testify against Hall in another case.

Co-defendants David Chalue, 46, of North Adams, and Caius Veiovis, 32, of Pittsfield are to be tried separately.

Hall was found guilty on the three counts of murder in the first degree, three counts of  kidnapping and three counts of intimidation of a witness or other person.

He was also found guilty on a charge of intimidation of a witness or other person related to an incident with 24-year-old woman in Pittsfield July 2012; and single counts of kidnapping, possession of a firearm during the commission of a felony and a count of conspiracy in the intimidation of a witness or other person in connection with a plot to kidnap and intimidate Glasser on Aug. 14, 2010. He was found not guilty on another intimidation charge.
 
The jury found Hall guilty of single counts of armed robbery, assault and battery by means of a dangerous weapon and count of intimidation of a witness or other person from another incident, in Peru, involving Glasser that occurred on July 21, 2009. However, he was not found guilty of kidnapping and extortion by threat of injury.

Judge C. Jeffrey Kinder ordered that Hall be held without bail pending sentencing on Monday, Feb. 10, at 9 a.m.

The investigations were conducted by the Berkshire Detective Unit assigned to the district attorney’s office and the Pittsfield Police Department. They were assisted by the FBI,  the Berkshire County sheriff's office and members of the Berkshire County Drug Task Force.

"I want to extend my appreciation and thanks to the jury for providing five weeks of service on behalf of their fellow citizens, their attention to the evidence throughout the trial, and for their obviously careful and thoughtful consideration of the evidence in the case. I also want to thank all of the many witnesses who came forward and testified," Berkshire District Attorney David F. Capeless said. "They should be congratulated for their willingness to share their testimony, and participate in the pursuit of justice on behalf of David Glasser, Edward Frampton and Robert Chadwell."

Capeless described the verdicts as resulting from a "through and relentless investigation" that will continue in the coming months as Chalue and Veiovis are tried.
