BROCKTON – The man wanted in connection with the brutal murders of a married couple found bludgeoned to death in their home has been arrested, Plymouth County District Attorney Timothy J. Cruz and Marshfield Police Chief Phillip A. Tavares have announced.
Today, Christopher Keeley, 27, of Weymouth, was arrested in Miami Beach, Florida. Keeley faces a rendition hearing in Florida before he is scheduled to be arraigned on two counts of Murder in Plymouth District Court.
On Tuesday evening at approximately 9:19 p.m., Marshfield Police received a call requesting that a well-being check be performed at a home located at 75 Gotham Hill Drive. Upon arrival, Marshfield Police officers discovered the bodies of a male and female victim with obvious signs of trauma. The victims, who were bludgeoned and stabbed, were determined to be deceased on scene. They have been identified as married couple, Carl Mattson, 70, and Vicki Mattson, 70.
Marshfield Police contacted the Massachusetts State Police Detective Unit assigned to the Plymouth County District Attorney’s Office, and an investigation commenced. Detectives developed probable cause and identified Christopher Keeley, 27, of Weymouth, as a person of interest in the double homicide.
On Wednesday, the Massachusetts State Police Commonwealth Fusion Center issued a BOLO alert for Keeley, and a 2019 black Jeep Wrangler. Investigators recovered and secured the Jeep at a parking lot in Avon. The motor vehicle was unoccupied.
Additionally, a dog missing from the 75 Gotham Hill Drive home was located deceased inside the home. Veterinary follow-up is being conducted.
The state Office of the Chief Medical Examiner accepted jurisdiction of the case and will determine the cause and manner of the victims’ deaths.
Preliminarily, this does not appear to be a random act of violence. The ongoing investigation is being conducted by Massachusetts State Police and Marshfield Police.
