A Chechen fatally shot while being questioned by the FBI about his ties to one of the accused Boston Marathon bombing suspects was "a good boy" whose killing was "unjustified," the man's father and his attorneys said on Tuesday (August 13).

Abdulbaki Todashev, whose 27-year-old son Ibragim was shot in Florida on May 22 while being interrogated by the FBI and Massachusetts State Police, spoke about his son through an interpreter at a news conference arranged by the two Florida law firms now representing his family.

"My son was a very good boy," Todashev said. "He was a good grandson for his grandparents, he was a good brother, he was a good neighbor, he was a good family member, we loved him very much and he loved us back. "

He said his only hope was justice for his son.

The elder Todashev recently arrived in the United States from Russia to retain the lawyers now looking into possible civil action against the FBI. His son's death stemmed from a probe into the Boston Marathon bombing on April 15, which killed three people and injured more than 260.

Ibragim Todashev, who trained as a mixed martial arts fighter, was an acquaintance of Marathon bombing suspect Tamerlan Tsarnaev and worked out at the same gym used by Tsarnaev in Boston before moving to Florida, according to attorney Eric Ludin.

The FBI has said Todashev was being questioned at his apartment in Orlando when he suddenly attacked an agent and was shot and killed. His father has openly questioned that account and said his son was unarmed when he was shot seven times.

He has also dismissed U.S. media reports following his son's death suggesting his son may have grabbed a kitchen knife or tried to wrest a gun from an agent as "absurd," saying there was no reason trained officers could not subdue a lone young man without killing him.
