SPRINGFIELD, Mass. (AP) -- A judge has ruled that witnesses will be allowed to refer to a triple-slaying suspect as a member of the Hells Angels, despite objections from the defense.

Defense lawyer Alan Black argued Thursday that the constant repetition of Hells Angels will have a cumulative effect of making the jury think Adam Lee Hall of Peru, Mass., is a bad guy and therefore guilty. He wanted Hall referred to only as a member of a "motorcycle club."

The 36-year-old Hall and two other men are charged with shooting David Glasser, Edward Frampton and Robert Chadwell in Pittsfield in 2011. Authorities say Hall wanted Glasser dead so he couldn’t testify against him in another case. Prosecutors say the others were killed to eliminate witnesses.

Hall denies involvement.

Opening statements are Monday.
