WEYMOUTH — The shooting of a Weymouth Police Officer Sunday morning has turned fatal.

Multiple media outlets report that authorities have confirmed the deaths of 42-year-old Weymouth Police Officer Michael Chesna and an unidentified woman. Chesna was shot several times this morning while in pursuit of a suspect in the Burton Terrace neighborhood of the town.

In a press conference, authorities said it's believed that the suspect, identified as Emanuel Lopes, had struck Chesna in the head with a stone while Chesna was attempting to arrest him. Lopes then took Chesna's firearm and shot him in the head and chest. Chesna was taken to South Shore Hospital where he was pronounced dead.

After shooting Officer Chesna, the suspect continued to run from Weymouth Police through the back yards of multiple residences in the neighborhood. During this foot pursuit, Lopes fired another three rounds, one of which fatally struck a woman who was inside her home. The woman's identity is being withheld at this time pending notification next of kin.

Only a block away at South Shore Hospital, another crime scene has been established. It is believed the situation began with someone driving erratically near the hospital before hitting another car.

State police detectives assigned to the Norfolk County District Attorney's Office are involved in the investigation.

The shooting took place just three months after West Yarmouth Police Sergeant Sean Gannon was shot and killed in the line of duty.
