Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev  say they remain concerned about being ``adequately prepared'' for a November trial in his death penalty case. Tsarnaev has pleaded not guilty to 30 federal charges.

The defense and prosecutors in court filings yesterday proposed deadlines for each side to give the other pretrial material.

The defense wants the government's experts' reports earlier. Prosecutors say both sides should have the same deadlines.
