Triple Murder From 2011 - Solved?

It appears that the Boston Bombers were involved in a triple murder from back in 2011.

The bodies were discovered the next day. Former Middlesex District Attorney Gerry Leone said at the time that the murders were "graphic." Other investigators called it perplexing.

Roughly seven pounds of marijuana was dumped on the bodies and $5,000 in cash was left behind. Neighbors said they did not hear any signs of trouble – even with open windows – and there was no forced entry. In a 2011 interview, Leone said investigators theorized there had been more than one person at the scene of the murders based on "many factors," but no suspects were identified.

From there the case went cold, until photos of the Boston Marathon suspects were released and family and friends of the Waltham victims recognized them and remembered Tamerlan's strange behavior after the murders. He did not attend his friend's funeral and vanished from the martial arts gyms where the men had sparred together.
