WASHINGTON (CNN) -- Preliminary talks have been under way "for the past few days" to allow Boston bomb suspect Dzhokhar Tsarnaev to resume providing investigators with information about the attacks in exchange for having the death penalty taken off the table, two government sources say.
Negotiations are in the very early stages, and not a sign lawyers for the 19-year-old suspect are ready to make a deal, said one source, who did not want to be identified because of the sensitive nature of the private discussions.
The discussions between prosecution and defense are at a "preliminary, delicate stage" and both refused to offer details of what either side would be willing to leverage, according to the sources.
