BROCKTON, Mass. — A man has been arraigned on murder charges in connection to the killing of a married couple found bludgeoned to death in their Marshfield home and also killing the couple’s dog, Plymouth County District Attorney Tim Cruz said Tuesday.
Christopher Keeley, 28, pleaded not guilty in Brocton Superior Court on two counts of murder in the deaths of Carl and Vicki Mattson, both 70 years-old. He is currently being held without bail, according to Cruz.
On Nov. 29, 2022, at approximately 9:19 p.m., Marshfield Police received a call requesting a well-being check at a home at 75 Gotham Hill Drive. When officers arrived, they found the bodies of a man and a woman with obvious signs of trauma. The Mattsons, who were bludgeoned and stabbed, were declared dead at the scene.
