The girlfriend of one of the three men brutally killed in a Waltham, Massachusetts apartment in 2011 has revealed that she told police soon after the murders that Boston Marathon bombing suspect Tamerlan Tsarnaev had been a frequent visitor to the apartment.

The woman, who hasn’t been named, was the girlfriend of Brendan Mess, 25. On Sept. 11, 2011 she found his dead body along with those of Erik Weissman, 31, and Raphael Teken, 37.

Earlier this week Chechan immigrant Ibragim Todashev, 27, was killed by FBI agents but not before he implicated himself and Tsarnaev in the 2011 triple slaying.

A homicide investigation into the 2011 slayings had appeared to have stalled until friends and relatives of Mess reported a possible link to Tsarnaev after his picture was released as a suspect in last month bombings.

The woman, an African immigrant, also revealed that prior to his death, Mess had kept a handgun in his apartment but that police had told her after the bodies were discovered that it was missing. 

It is believed that Mess’s missing gun was the same weapon Tsarnaev used when he shot MIT police Officer Sean Collier dead on the night of April 18 and wounded other officers shortly afterwards in the shoot-out in Watertown, Boston.
