Prosecutor To Discuss Shootout With Boston Marathon Bombers

A Massachusetts prosecutor has scheduled a news conference to discuss her office's investigation into the April 2013 shootout that left one of the Boston Marathon bombers dead and nearly killed a police officer.

Middlesex District Attorney Marian Ryan is scheduled to make a statement Tuesday regarding the investigation.

The armed confrontation in suburban Watertown on April 19, 2013 ended with the death of bomber Tamerlan Tsarnaev and left MBTA Officer Richard Donohue clinging to life after getting shot. Donohue only returned to work last month.

The shootout was four days after two pressure-cooker bombs exploded at the marathon finish line, killing three people and injuring more than 260.

Tamerlan Tsarnaev died after getting run over by his brother, Dzhokhar, who was sentenced to death last month.
