A Massachusetts police officer and an elderly woman were killed Sunday after a suspect attacked the officer with a rock, took his gun and shot him in the head and chest, officials said.
Weymouth police officer Michael Chesna, 42, was pronounced dead at a local hospital shortly before 8 a.m. The unidentified woman was fatally wounded by stray bullets in a nearby home. A suspect, identified as Emanuel Lopes, was in custody and was expected to be arraigned on two counts of homicide Monday.
