Officials seek to prosecute Tsarnaev in Mass.

WOBURN — As accused Boston Marathon bomber Dzhokhar Tsarnaev awaits trial on federal terrorism charges, local authorities are seeking to prosecute him in state court in the killing of MIT police Officer Sean Collier and a shootout with Watertown police officers.

Authorities in Middlesex County have obtained a warrant for Tsarnaev, who is being held in federal prison, so they can pursue murder charges against him after his federal trial is over.
