A Canaan, N.Y., man is being held on $1 million bail for allegedly helping a ranking Hells Angeles member and others dispose of three murder victims in Berkshire County. A plea of not guilty was entered on behalf of 62-year-old David Casey in Central Berkshire District Court on Monday. He is charged with accessory after the facts of murder, kidnapping and intimidation of a witness. It was not immediately clear if he has an attorney. Authorities say 34-year -old Adam Lee Hall, 44-year-old David Chalue and 31-year-old Caius Veiovis were involved in the disappearance and killing of David Glasser, Edward Frampton and Robert Chadwell. They were discovered Sept. 10. Glasser was expected to testify this month in the robbery, assault and kidnapping trial of Hall, the reputed sergeant at arms of the Berkshire County chapter of the Hells Angels.
