BOSTON (MyFoxBoston.com) -- A new report suggests Russian officials warned the FBI of Tamerlan Tsarnaev's alleged connection to militant Islamists well before the Boston Marathon bombings.
According to the Boston Globe, a Congressional report finds Russian authorities notified the FBI of Tsarnaev's connections in March 2011. The agency reportedly opened an investigation into Tamerlan that same month and interviewed him in person.
A memo was also reportedly sent to a customs database that would trigger an alert whenever he left or re-entered the country, but the investigation was closed just three months later after it was concluded that he had no links to terrorism.
In January 2012, Tsarnaev went to JFK International Airport to board a flight to Moscow. He reportedly triggered an alert, but was not considered a high priority among 100 other names on a "hot list" of people traveling through the airport that day. The report blames his name being misspelled.
Tsarnaev spent six months in Dagestan before returning in July 2012. He was not detained or questioned going through security.
Tamerlan was killed in a shootout with police after being hit by a car driven by his brother, Dzhokhar, days after the bombing.
A Congressional report on Tsarnaev is expected to be released this week.
