A man who has bumps resembling horns implanted in his forehead has been found guilty of murder and other charges for his role in the kidnapping and slaying of three Massachusetts men in 2011.

Caius Veiovis (KYE'-us vee-OH'-vis) yelled at the Springfield jurors who convicted him Friday, saying, "I'll see you all in hell!" They had considered his case for the past week.

Veiovis was convicted of killing David Glasser, Edward Frampton and Robert Chadwell. The remains of the three Pittsfield men were buried on private property in Becket.

The two other men charged in the killings already were convicted.

Authorities say one of those co-defendants wanted Glasser dead so he couldn't testify against him in another case. The others were killed to eliminate witnesses.
