Boston bomber Tamerlan Tsarnaev did participate in a brutal triple murder 16 months before the deadly marathon attack according to court records filed on Tuesday.

Brendan Mess, described as Tsarnaev's 'only American friend', Raphael Teken and Erik Weissman were murdered at their home in Waltham, Massachusetts on the 10th anniversary of 9/11.

Their bodies were found covered in marijuana in the apartment and at the time authorities revealed their throats had been slit with a knife or ice pick and around $5,000 was left at the scene.

The startling disclosure was made by federal prosecutors who are trying to prevent his younger brother's legal team from obtaining documents concerning the killing of the three men on September 11, 2011.

It is the first official statement that links the now-dead elder Tsarnaev to the unsolved crime and raises questions about the death in May of his friend Ibragim Todashev, who allegedly confessed his and Tsarnaev's involvement to FBI agents before he was shot dead after charging them.

'According to Tsarnaev's friend Ibragim Todashev, Tamerlan Tsarnaev participated in the Waltham triple homicide,' prosecutors wrote in a motion filed on Monday according to MyFox Boston.
