Russia did not share some intelligence that could have subjected one of the Boston Marathon bombing suspects to greater scrutiny before the attacks, according to an unreleased government review.
The New York Times, citing unnamed sources, reports that the review claims Russia told the FBI of Tamerlan Tsarnaev’s radicalization during a trip to the country but declined to share additional data, including information from an intercepted phone conversation he had with his mother about Islamic Jihad, prior to the attack.
Law enforcement in the U.S. considered Tsarnaev more of a threat to Russia at the time, though it’s unclear the extent to which the additional information could have helped them prevent the attack.
The government report, which also finds some faults in the FBI investigation before the attack, was compiled by the inspector general of the Office of the Intelligence Community, which has oversight over the disparate federal agencies. Congress will be briefed on the report Thursday, and some findings are expected to be released to the public on Tuesday, the attack’s one year anniversary.
Authorities believe the suspected brothers attacked alone in the bombings that killed three people and wounded 264. Tsarnaev was killed evading police days after the attack. His younger brother Dzhokhar Tsarnaev has pleaded not guilty to 30 federal charges, some of which carry the death penalty, and his trial is slated to begin in November.
