SPRINGFIELD, Mass. (AP) -- Jurors have the case of a Hells Angels motorcycle club member charged with killing three Pittsfield men in 2011.

Deliberations began Monday afternoon and continue on Tuesday.

Adam Lee Hall of Peru, Mass., and two other men are charged with fatally shooting David Glasser, Edward Frampton and Robert Chadwell. Hall ‘s is the first trial.

In his closing, Berkshire District Attorney David Capeless said Hall had an "obsession" to keep Glasser from telling how he beat Glasser with a baseball bat. He said the others were killed to eliminate witnesses. Capeless called the evidence "clearly convincing."

Defense attorney Alan Black said there’s no physical evidence linking Hall to the killings. He said Hall is accused of chopping up the bodies to hide them, but no blood or DNA from the victims was found on Hall or his possessions.
