Convicted Boston marathon bomber Dzhokhar Tsarnaev could stand trial on state charges for the murder of a police officer despite being on death row at a federal prison, a report said Saturday.
Tsarnaev was convicted in federal court in Boston in April and formally sentenced to death last month over the 2013 bomb attacks that left three dead and 264 injured in one of the bloodiest assaults in America since the September 11, 2001 attacks.
The 21-year-old Tsarnaev was found guilty on all counts related to the bombings, the subsequent murder of Massachusetts Institute of Technology (MIT) police officer Sean Collier, a carjacking and a shootout while on the run.
