Tamerlan Tsarnaev, the Chechen immigrant to United States and one of the prime suspects in Boston Marathon bombings has been implicated in a 2011 triple homicide, according to newly filed court papers by federal prosecutors.

Tsarnaev, whose uncle Ruslan Tsarnaev was curiously married to the daughter of CIA officer Graham Fuller for three years, participated in the triple homicide at an apartment in Waltham, Massachusetts in September 2011.

The clinching proof came during interrogation of another Chechen immigrant Ibragim Todashev, who was a close acquaintance of Tamerlan from their days as mixed martial-arts trainees in Boston. According to narrative presented by FBI, which has raised serious suspicions, Todashev was killed while scuffling with an FBI agent, who then shot and killed the Chechen.

FBI claims that Todashev told them that Tamerlan Tsarnaev slayed the three men believed to be his close friends over a drug related dispute. On September 12, 2011, the marijuana sprinkled bodies of three victims, Brendan Mess, 25; Erik Weissman, 31; and Raphael Teken, 37, were found in the Waltham apartment.

The 23-page court filing brief argues against a motion by the lawyers for Dzhokhar Tsarnaev, 20; Tamerlan’s younger brother and accomplice, charged in the marathon bombings.

Dzhokhar Tsarnaev’s lawyers have filed the motion with the court to force the federal government to share pertinent investigative materials related to the older brother, but prosecutors objected on the grounds that disclosure of the materials sought by the defense could imperil the continuing investigation into the triple homicide.

On April 15, the two ethnic Chechens, reportedly planted two pressure-cooker bombs, commonly used by Asians to cook rice, that detonated near the finish line of the Boston marathon on the historic Boylston street. The bombings killed three and injured 264 others. In a related tweet, FBI Boston denied any links with Tsarnaev brothers prior to Boston bombings:

After allegedly shooting a law enforcement officer to death in an ambush near MIT, Cambridge, 72 hours later, the duo engaged in a middle of the night gun fire with police near Watertown. Tamerlan Tsarnaev was killed in the exchange, but Dzokhar escaped. He was later captured in a massive manhunt, while most of Boston urban area was locked down like a police state.

Dzhokhar’s lawyers have said that he is pleading innocence on all charges related to bombings and the officer’s murder.

In September 2004, Chechen-Ingush terrorists occupied School Number One in Beslan, Russia, and captured over 1100 people, including 777 children as hostages, resulting in deaths of 380 people, most of them innocent children. http://www.youtube.com/watch?v=DG1aZSckpiw
