Lawyers for suspected Boston Marathon bomber Dzhokhar Tsarnaev on Friday said his older brother, Tamerlan Tsarnaev was the mastermind behind the incident that killed three people, and he was asked to be an informant for the FBI.
The lawyers said Tamerlan Tsarnaev had been encouraged by the FBI to observe and report on the Chechen and Muslim community and asked for the release of documents proving their assertion.
“We seek this information based on our belief that these contacts were among the precipitating events for Tamerlan’s actions during the week of April 15, 2013, and thus material to the defense case in mitigation,” the lawyers said in a court filing. "We base this on information from our client’s family and other sources that the FBI made more than one visit to talk with Anzor [his father], Zubeidat [his mother] and Tamerlan, questioned Tamerlan about his Internet searches, and asked him to be an informant, reporting on the Chechen and Muslim community."
“We do not suggest that these contacts are to be blamed and have no evidence to suggest that they were improper, but rather view them as an important part of the story of Tamerlan’s decline. Since Tamerlan is dead, the government is the source of corroboration that these visits did in fact occur and of what was said during them," the filing continued.
