WASHINGTON -- A Florida prosecutor and an internal FBI investigation have cleared an unnamed FBI agent in the shooting of a 27-year-old man connected to the brothers accused of the Boston Marathon bombing, a law enforcement official confirmed to The Huffington Post. A separate inquiry by the Justice Department's Civil Rights Division is expected to follow suit, the official said.

Ibragim Todashev was killed in his apartment when he allegedly got into a tussle with the agent while being questioned. The agent was probing Todashev's suspected involvement in a triple murder in 2011 that might have been connected to him and Boston Marathon bombing suspect Tamerlan Tsarnaev. Tsarnaev was killed in the events following the bombing, and his younger brother Dzhokhar is currently facing federal charges.

The unnamed FBI agent was injured during the dispute. Additional information on the investigations of the incident are expected next week, though it isn't clear exactly how many details would be provided. CNN first reported on the findings of the Justice Department's civil rights probe, while The Washington Post reported on the Florida prosecutor's investigation.
