Boston Bombing Suspect Accepted His Participation in the Attack: Prosecutors

Dzhokhar Tsarnaev, the alleged coauthor of the Boston bombings, admitted to participating in the attack during an interrogation in the hospital a day after his arrest, United States prosecutors revealed in a joint statement on Wednesday.

Tsarnaev, who was then 19 years old, had said that he and his brother, who died after a shootout with the police days after the bombing attacks which killed three people and injured 264 during the Boston marathon on April 15, 2013, were the only ones involved in the attacks, reported Reuters on Thursday.

However, investigators suspect that the two brothers did not act alone. According to the news agency, prosecutors assured in the statement that "Agents continue to interrogate Tsarnaev not to obtain an interrogation, which they already had, but because they had reason to believe that he was witholding information on imminent attacks, accomplices and or the existence of additional bombs."

"The bombs used during the marathon were made using improvised fuses made from Christmas lights, and with remote controlled detonators made from remote control toys. These relatively sophisticated devices would have been difficult to create successfully by the Tsarnaev brothers without the training or help of someone else," reads the legal document, reported CNN.

All the information the suspect gave to investigators during an interrogation in a hospital a day after being arrested and others made later, but before he was informed of his legal representation rights, must be admitting during the trial which will be carried out against him, since the agents that interviewed him suspected that he was still a risk for the public due to the possibility of more attacks, quoted the mentioned source.

The suspect's lawyers had said that the evidence gathered during the interrogations in the hospital should not be admitted in court, under the argument that his client was forced to make incriminatory statements.
