The FBI was involved in a fatal shooting near Universal Studios in Orlando, Fla., early Wednesday that killed a man with ties to the older brother suspected in last month's deadly terrorist bombing at the Boston Marathon.
CBS News senior correspondent John Miller, a former FBI assistant director, reported on "CBS This Morning" that the man, Ibragim Todashev, was friends with Tamerlan Tsarnaev, a suspect in the attack that killed three people and injured more than 260 others.
The FBI has not commented on the relationship between Todashev and Tsarnaev.
Miller reported that FBI agents went to Todashev's apartment complex after midnight Wednesday morning to question him. Todashev had been on the bureau's radar since Tsarnaev was identified as a suspect in the bombing.
"He had been interviewed along with a number of other people in the apartment complex, but the interest in him was higher because of a couple of factors: He was in contact with Tamerlan Tsarnaev. He had been to Boston to visit him, and he was planning a trip to Chechnya," Miller said.
FBI agents went to question him overnight after there were indications that he canceled that trip, Miller said.
"In the encounter in the apartment, something went wrong," Miller said.
In a statement Wednesday, the FBI said, "We are currently responding to a shooting incident involving an FBI special agent. The incident occurred in Orlando Florida. The agent encountered the suspect while conducting official duties. The suspect is deceased. We do not have any further details at this time. We expect to have more information later this morning."
Tamerlan Tsarnaev was killed in a shootout with police outside Boston in the days after the marathon bombings. His younger brother, Dzhokhar Tsarnaev, remains in federal custody awaiting trial.
