It's been less than 24 hours since Ibragim Todashev, 27, was shot and killed and already the conspiracy theories have started.

Todashev was killed during the course of an FBI interrogation, reports claim. As ILLUME reported earlier, Todashev was of Chechan descent and was being questioned based on his reported ties to Tamerlan and Dzhokhar Tsarnaev, the Boston Marathon bombers, also of Chechan descent.

While little was known about the connection between Todashev and the Tsarnaevs, more details are starting to emerge.

So what was it that caused the FBI to shoot and kill Todashev? And was it legal?

Normal interrogation doesn't allow for the excessive use of force. But there are some legal exceptions to that notion-- namely when the interrogator feels that there is an imminent threat of harm. Police and other state officials benefit from "qualified immunity," which essentially states that they can't be sued for harm they cause while conducting official duties and while acting within the scope of their employment.

It's all a grey area of law and proving any wrongdoing on the part of the FBI will be tricky, if not impossible.

The IDesignTimes goes into detail about Todashev's final moments, claiming that he "felt inside he was going to get shot," according to a Khusn Taramiv, a friend of Todashev's, who was also questioned with him.

The questioning intially involved Todashev's role in a triple homicide from 2011 in Waltham, Massachusetts. Three victims were found with their throats slashed and marijuana spread over their bodies, writes NBC News. Todashev allegedly confessed to his role in these murders.

But that wasn't enough for the conspiracy theorists. Taramiv claimed that Todashev was initially cooperating with investigators. He also told reporters that Todashev believed that the FBI was framing his involvement with the Boston Marathon bombings.

But FBI officials say that Todashev attacked them with a knife.

Little is known about Todashev. According to The Orlando Sentinel, Todashev was a "gifted athlete."

In the days following the Boston Marathon bombings, Todashev had been questioned relentlessly by the FBI, according to his former roomates.

"They pretty much kidnapped him in front of his place," his friend Khusen Taramov told The Orlando Sentinel.

But how close was he to Tamerlan Tsarnaev? And how close could he have been, living in Orlando?

Was Ibragim Todashev set up by the FBI or was his killing an unfortunate occurrence in normal FBI practice?

These questions-- and many more-- will remain unanswered in the aftermath of the Boston Marathon bombings.
