The triple murder case involving a local Hells Angels member and two others is before a grand jury and a second case involving the same biker is heading there as well. According to a source close to the case, the grand jury is in session and interviewing witnesses in the Aug. 28 murder of three Pittsfield men. Adam Lee Hall, 34, of Peru; Caius Veiovis, 31, of Pittsfield; and David Chalue, 44, of North Adams and Springfield, allegedly kidnapped then murdered David Glasser in order to keep him from testifying against Hall, a member of the Berkshire County chapter of the Hells Angels, in an assault and kidnapping trial that had been set to begin Sept. 19. The two other victims, Edward Frampton -- Glasser's roommate -- and their friend, Robert Chadwell, were killed because they were at the wrong place at the wrong time, according to police. All three were allegedly abducted Aug. 28 from 254 Linden St., where Glasser and Frampton lived. A fourth defendant, David Casey, 62, of Canaan, N.Y., has been charged as an accessory to the murder for allegedly helping Hall bury the bodies with an excavator in Becket. It was unclear whether Casey was part of the current grand jury proceedings. All four defendants have pleaded not guilty. The grand jury is a secret proceeding made up of no more than 23 jurors who serve for up to three months. Unlike a criminal trial, the prosecutor questions witnesses, Advertisement while any attorney representing a witness is excluded from objecting, arguing or addressing the prosecutor or the jurors, according to the state's criminal procedure law. If at least 12 jurors find there is enough evidence, then the defendants can be indicted and the case can move on to the superior court level. Hall is also facing child pornography and extortion charges for allegedly forcing a 16-year-old to send him nude photographs of herself. He was arraigned Sept. 6 in Central Berkshire District Court on those charges. On Sept. 29, the Berkshire District Attorney's Office pulled the case from district court in order to bring it to the grand jury in hopes of prosecuting Hall on the charges in superior court. Meanwhile, the police investigation is continuing. The case is headed up by the Massachusetts State Police and the Pittsfield Police, with the assistance of the FBI and other agencies, under the direction of the district attorney. Investigators were back at Hall's compound located at 40 East Main St. in Peru on Monday and were seen digging on the property with an excavator. A large-scale police search had been conducted at the site last month. The warrants in the case were set to be unsealed this week, but at the request of authorities, they won't be revealed until the end of the month
