Three claddagh rings help police identify the remains of Whitey Bulger’s alleged victims, a Boston court heard Thursday.

The Boston Herald reports that at least three of the Southie men Whitey murdered and then dumped into shallow graves were wearing claddagh rings.

The traditional Irish ring is made up of two hands, holding a crowned heart  that represent love, loyalty, and friendship.

The rings were found in different shallow graves with the skeletal remains of two members of the old Mullens gang, Tommy King and Paul McGonagle.

A third ring was also found near the body of John McIntyre, shot in the head five times by Whitey and buried in Dorchester.

Dr. Ann Marie Mires, a Massachusetts state forensic anthropologist testified this week, showing jurors gruesome photos of human remains found in shallow graves in the Boston area.

Jurors were shown several photos of human remains including parts of a pelvic bone, a fractured skull with decomposed brain matter and a claddagh ring with part of a decomposed finger bone, CNN reports.

Bulger is charged in the deaths of 19 people during some two decades when prosecutors say he ran Boston's Irish gang ‘The Westies’.

He was arrested in June 2011 in Santa Barbara, California after 16-years on the run.

Bulger, 83, faces the possibility of life in prison if convicted on charges related to the killings, racketeering and drug dealing. He has pleaded not guilty to all of the charges
