The United States Department of Justice will be conducting a federal inquiry into the shooting death of Ibragim Todashev.

Ibragim Todashev was shot and killed by FBI officials during an interview at his Florida apartment, after hours of interrogation.

Todashev was know to be an acquaintance of Tamerlan Tsarnaev, one of the two alleged Boston Marathon bombers. Tsarnaev died in April after a shoot out with police, but his brother Dzhokhar Tsarnaev is still alive, and recently pleaded "not guilty" to the charges stemming from the Boston Marathon. The bombing left three people dead and over 200 injured.

The Criminal Section of the DOJ's Civil Rights Division will be conducting the investigation alongside the U.S. Attorney's Office for the Middle District of Florida.

The two will be reviewing and investigating to see if there was any criminal conduct by the FBI officials who interrogated and subsequently killed Todashev.

Little is known about the events that led to Todashev's death. Todashev was reportedly unarmed when he was shot and killed by the FBI agents, although the FBI's initial reports claimed that he was lunging for a sword that was in the room at the time.

In an earlier call with the Council of American Islamic Relations' Florida office, Executive Director Hassan Shibly said many questions remained. CAIR's Florida office will be representing the Todashev family. The office is also leading its own separate independent investigation into the killing.

"We welcome this federal inquiry as a first step to help provide answers to the family of Mr. Todashev and to ensure that our law enforcement officials are abiding by the highest standards," says Shibly.
