A friend of the deceased Boston Marathon bombing suspect told investigators that two years before allegedly setting off explosives that killed 5 people and wounded more than 250 others, Tamerlan Tsarnaev participated in an unsolved 2011 triple homicide, according to a court filing made Monday by federal prosecutors..

Ibragim Todashev was shot dead by an FBI agent in May when he allegedly attacked him during an interview at his Orlando, Fla. apartment. ABC News reported he was about to sign a statement confirming his and Tsarnaev's involvement in the murders. The court documents did not elaborate on Tsarnaev's alleged involvement.

Police found Brendan Mess, 25, Erik Weissman, 31, and Raphael Tekken, 37, dead in a Waltham, Mass. apartment on Sept. 12, 2011 with their throats slit ear-to-ear and covered in marijuana. Mess and Tsarnaev were reportedly friends who boxed together.

Tsarnaev's involvement in the murders had been previously reported in the aftermath of the Boston Marathon bombing, though the court filing is the first formal accusation.

Federal prosecutors are attempting to block defense attorneys for the surviving Boston bombing suspect, Dzhokhar Tsarnaev, from gaining access to investigative documents, reported The Boston Globe. Prosecutors said releasing their evidence would jeopardize the investigation into the Waltham murders.

"Any benefit to Tsarnaev of knowing more about the precise 'nature and extent' of his brother's involvement does not outweigh the potential harm of exposing details of an ongoing investigation into an extremely serious crime, especially at this stage of the proceedings," prosecutors wrote.

Tamerlan Tsarnaev, 27, was killed in a shootout with police on April 19. Dzhokhar Tsarnaev, 20, is facing the death penalty for his alleged involvement in the April 15 attack. He pleaded notguilty to all 30 federal charges, including using a weapon of mass destruction, in July.
