Officials in the United States say the surviving suspect in the Boston bombings has acknowledged his role in the attacks. However it is unclear whether the admission could be used at a criminal trial because it happened before authorities advised Dzhokhar Tsarnaev of his constitutional rights.
It is also unclear whether prosecutors would need the admission by Dzhokhar Tsarnaev to secure a conviction because physical evidence has already been uncovered in the investigation.
