The evidence was disclosed recently by federal prosecutors working on the trial of his brother, Dzhokhar.

Law enforcement sources familiar with shooting in May told NBC that Todashev and Tsarnaev carried out the 2011 killings when a drug deal turned violent. The suspects didn't want the three victims to be able to identify them, so they slit their throats.

The bodies were found with marijuana sprinkled on top of them. There was also $5,000 in cash in the room.
