BOSTON — The name of a police patrolman who was wounded by shrapnel during a confrontation with the Boston Marathon bombers and suffered a fatal brain aneurysm a year later has been added to a memorial for Massachusetts police officers.

Officer Dennis Simmonds suffered a head injury when brothers Dzhokhar and Tamerlan Tsarnaev detonated an explosive device during a shootout in Watertown days after the April 2013 marathon bombing.

In April 2014, Simmonds collapsed and died while working out at the Boston Police Academy gym. He was 28. A state medical panel says the aneurysm likely was related to the injury.
