Whatever the outcome of the ongoing federal trial of accused Boston Marathon bomber Dzhokhar Tsarnaev, a new local indictment promises his court days are far from over.

Tsarnaev has been indicted by a Middlesex County grand jury for the murder of MIT officer Sean Collier on the evening of April 18, 2013. 

Collier was shot as the Boston Metro area remained on lockdown after the bombing of the annual event.

The Middlesex D.A. will start prosecution when the federal case wraps up, his office said.

“Dzhokhar Tsarnaev has been indicted by a Middlesex County Grand Jury for the murder of Sean Collier and we intend to move forward with criminal charges against Tsarnaev after the current federal trial is completed,” District Attorney Marian T. Ryan said in a statement.

“In addition, the investigation remains active into the incident which occurred on Laurel Street in Watertown on Friday, April 19. The written investigatory report concerning the Laurel Street incident is anticipated to be completed within two months.”

Tsarnaev's defense team has portrayed him as under undue influence from his older brother, Tamerlan Tsarnaev, who was shot dead during a Watertown faceoff with cops.

The older brother, defense lawyers say, was the mastermind.
