Police Officer Michael Chesna was shot and killed with his own service weapon after responding to reports of an erratic driver on Burton Terrace, behind South Shore Hospital, shortly after 7:30 am.
When he arrived at the scene he discovered that the vehicle had crashed and he found the driver vandalizing a home nearby. The man attacked Officer Chesna, striking him in the head with a large rock. The subject then disarmed him, shot him in the head and chest, and fled the scene.
The man fatally shot a woman in her home before being wounded by other responding officers and taken into custody. He was charged with two counts of homicide.
Officer Chesna had served with the Weymouth Police Department for six years. He is survived by his wife and two children.
