Ibragim Todashev, the 27-year-old Chechen immigrant shot dead by an FBI agent in Florida last week, was executed, his father claimed at a Thursday press conference in Moscow.

"I have 16 photographs. I just would like to say that looking at these photos is like being in a movie. I only saw things like that in movies: shooting a person, and then the kill shot. Six shots in the body, one of them in the head," said Abdulbaki Todashev as he displayed photographs of his dead son's body.

"I want justice and I want an investigation to be carried out," he said, according to RT. "I want these [FBI agents] to be put on trial in accordance with U.S. law. They are not FBI officers, they are bandits. I cannot call them otherwise, they must be put on trial."

The young man was being questioned by FBI agents and Massachusetts State Police officers, according to an FBI statement released hours after the May 22 shooting, "when a violent confrontation was initiated by the individual," resulting in his death.

Todashev's father said his son doubted that the Tsarnaev brothers were behind the Boston Marathon bomb attacks. Todashev knew Tamerlan Tsarnaev when he lived in the Boston area and both men enjoyed mixed martial arts.

"My son never believed that they did it and kept telling me it was a set-up," the dead man's father said at the Thursday press conference, according to the Voice of Russia. "Maybe my son knew something, some information the police did not want to be made public. Maybe they wanted to silence my son."

Law enforcement sources told NBC News and CNN last week that Todashev was shot after he confessed to murdering three people in September 2011 with Tamerlan Tsarnaev, the alleged Boston Marathon bomber who died in a April 19 gun battle with police.

The Washington Post reported Wednesday that, according to two law enforcement sources, Todashev was unarmed when he was shot. One source said he lunged at the FBI agent who shot him, another simply said he was unarmed.

The Florida chapter of the Council on American-Islamic Relations is aggressively calling for an independent investigation. CAIR-Tampa Executive Director Hassan Shibly told the Orlando Sentinel Wednesday that he too had photos of Todashev's corpse, which he said were taken by Khusen Taramov, a friend of Todashev's who was also interrogated the night he died.

"We did confirm today with sources within the FBI that he was unarmed," Shibly told the Sentinel.

"They were talking to us, both of us, right?" Taramov told WESH-TV immediately after the shooting. "And they said they need him for a little more, for a couple more hours, and I left, and they told me they're going to bring him back. They never brought him back."

Todashev reportedly purchased a ticket to Russia and planned to visit Chechyna this summer, increasing the interest of investigators. The FBI is currently reviewing the incident and has provided few official statements.

"For some reason the FBI really wanted to present my son as Tsarnaev's friend, but that was not true," the elder Todashev told The Daily Beast last week. "Before this trouble I thought America was a free democratic country, where unlike in Russia, laws worked. I was deeply mistaken — now I think Russia is a golden place compared to the United States."
