Boston bombing suspect made 'statement to his detriment'

March 1 (UPI) -- Prosecutors said special rules restricting the communications of suspected Boston Marathon bomber Dzokhar Tsarnaev should stay in effect after a recent visit with his sister.

During the incident, Tsarnaev made a statement that compromised himself, prosecutors said in a filing made Friday.

The filing requested that measures stay in place limiting who Tsarnaev can communicate with, requiring government representatives be present during visits with certain people and restricting who his defense team can share information with, the Los Angeles Times reported. These are the same kinds of measures sometimes used in terrorism cases in which authorities believe the defendant could cause bodily harm to those they have contact with.

“The motion has nothing to do with the [special measures] and everything to do with the fact that Tsarnaev, despite the presence of an FBI agent and an employee of the federal public defender, was unable to temper his remarks and made a statement to his detriment which was overhead by the agent,” the filing said.
