Uh Oh.

FBI agents violated the rights of Boston Marathon bombing suspect Dzhokhar Tsarnaev by continuously questioning him while he lay in pain in a hospital bed, even after he had asked for a lawyer 10 times and authorities had determined there were no other bombs or threats to public safety, defense lawyers argued in court documents filed Wednesday.

The attorneys asked a Boston federal judge to suppress all statements Tsarnaev made to law enforcement while he was hospitalized at Beth Israel Deaconess Medical Center in Boston.

“The questioning continued for hours, in what was obviously an effort to extract as much incriminating information as possible, without regard for the protections of the Fifth Amendment,” his lawyers wrote in the 21-page filing. At the time, Tsarnaev could not talk because of his injuries, so he answered questions in writing.

The lawyers also say that his hospital statements should be suppressed because they were involuntary. Tsarnaev was heavily drugged and in pain while he was being interviewed, they argue. His left eye was sutured shut, his jaw was wired closed and he was unable to hear out of his left ear. At times, his pen trailed off the page, indicating that he fell asleep or lost motor control.
