(MyFoxBoston.com) -- The father of Tamerlan Tsarnaev's friend who was shot to death by an FBI agent inside his Orlando, Fla. apartment reportedly penned a letter to President Barack Obama asking him to ensure authorities do not interfere with the investigation into his son's death.
Boston Magazine reports Abdul-Baki Todashev, Ibragim Todashev's father, released the open letter along with graphic images of the 27-year-old's body and his bloody apartment.
In the letter published by the magazine, Todashev accuses the FBI of "deliberately" killing his son so that "he can never speak and never take part in court hearings." He also claims the FBI put "pressure" on his son's friends in an attempt to prevent them from coming to the court and speaking the truth."
Ibragim Todashev was killed in May while FBI agents questioned him about his friendship with Tsarnaev. Officials originally said the Chechen man lunged at an agent with a knife. They later said it was not clear what had happened.
Florida state attorney Jeffrey Ashton said the investigation into Todashev's death would likely conclude and findings would be made public in early 2014.
Officials claim Todashev implicated Tsarnaev in a 2011 triple murder in Waltham, but his family and close friends say he was never interviewed about the matter and that his case was not handled professionally.
"We have just received Mr. Todashev's letter and will be reviewing it to determine the appropriate follow-up," said, the White House's National Security Council spokeswoman Caitlin Hayden, and referred to the FBI for further details.
The FBI told FOX 25 they are declining to comment on the letter.
