Authorities Investigating "Boston Bomber"'s Possible Connection To 2011 Homicide

An unsolved crime. "Tam"'s former friends have been suspicious since the bombing

Massachusetts investigators are looking at whether deceased bombing suspect Tamerlan Tsarnaev may have been involved with the unsolved triple murder of his best friend and two other men in Waltham in 2011, ABC News reported Monday.

A spokeswoman for the Middlesex County District Attorney's office told ABC that "We are looking at a possible connection with the suspect in the marathon atrocity and this active and open homicide in Waltham."

The DA's office did not immediately answer phone calls from BuzzFeed seeking additional comment.

Brendan Mess, 25, Raffael "Raffi" Teken, 37, and Erik Weissman, 31, were found dead in a Waltham apartment on September 12, 2011. Their throats had been cut and they had been covered in marijuana, as well as undergoing additional stab wounds. They were reportedly dragged to different rooms of the apartment to be killed.

Former friends of the men and of Tamerlan Tsarnaev have become suspicious of Tsarnaev, whom they knew as "Tam," in connection with the triple homicide since he was named as a suspect in the Boston marathon bombing.

"Tam wasn't there at the memorial service, he wasn't at the funeral, he wasn't around at all," Tsarnaev's former friend Ray, 26, who didn't want his last name used, said yesterday. "And he was really close with Brendan. That's why it's so weird when he said, 'I don't have any American friends.'"

Mess and Tsarnaev were boxing buddies and were by all accounts best friends.

"A few of my friends, without even speaking about it beforehand, have all been thinking this," Ray said of the Cambridge group of friends' suspicion that Tsarnaev may have been involved with the murder.
