But instead, officials said, the suspect, Emanuel Lopes, threw a stone at Chesna, which hit him in the head and knocked him down.
Authorities say Weymouth officer Michael Chensa was shot multiple times before 8 a.m. Sunday, and died from the injures at a hospital. The unidentified woman was fatally wounded by stray bullets in a nearby home.
Weymouth Police Chief Richard Grimes told media that Chesna was a veteran of the Iraq and Afghanistan wars and left behind a wife and two children, ages 4 and 9. He is being treated at South Shore Hospital.
Norfolk District Attorney Michael Morrissey says Weymouth police were responding to a report of a person driving erratically Sunday morning when they discovered a crashed BMW.
Lopes then allegedly shot Chesna in the head and chest, killing him.
Lopes, who was later arrested, suffered a leg wound. He will be arraigned on two counts of homicide on Monday, at either his bedside or in court. During that time he allegedly fired Chesna's gun three times at the officers.
As the procession traveled, dozens of police saluted the vehicle carrying Chesna and police placed bouquets by the Weymouth Police Headquarters.
"Officer Chesna has been an Army veteran, and in fact, I was speaking with his mom this morning, and she told me that he joined the military to help open the doors for him to get on this job".
"He always had a kind word and a good attitude. we very much appreciated his service to the Weymouth Police Department", said Grimes, describing the overnight shifts and traffic division duties Chesna held.
Chesna's body was transported from the hospital to the state medical examiner's office in Boston. The individual in question hurled rocks at the police officer, which hampered his ability to defend himself.
