GROZNY, June 25 (RIA Novosti) – The father of a Russian immigrant shot dead by the FBI during questioning in Florida said on Tuesday he would sue the US authorities over what he describes as the “extrajudicial execution” of his son.

Ibragim Todashev, 27, who had moved to the US from Russia’s Chechen republic several years earlier, was shot at his home in Orlando on May 22 while being questioned by the FBI about his links to Boston bombing suspect Tamerlan Tsarnaev and a possible connection to a 2011 triple murder in Massachusetts.

“FBI agents came to my son’s house and executed him, without filing any charges, with no lawyer, with no eyewitnesses. All I want is to obtain truth, justice and a punishment for those responsible, and so I intend to file a lawsuit against the authorities of that country [the US] to establish a truthful picture of what really happened,” Abdulbaki Todashev said in an interview with RIA Novosti in the Chechen capital of Grozny.

He said that the circumstances surrounding his son’s death remain unclear, with only conflicting media reports available.

Todashev, who brought his son’s body to Russia last week, said he would return to the United States soon “to seek the truth.”
