BROCKTON – Massachusetts State Police and Marshfield Police continue to search for the male suspect involved in the brutal murders of a married couple found bludgeoned to death in their home, Plymouth County District Attorney Timothy J. Cruz and Marshfield Police Chief Phillip A. Tavares have announced.

Last 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.

Earlier this morning, 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 this afternoon at a parking lot in Avon. The motor vehicle was unoccupied.

As a result of the ongoing investigation, search warrants have been executed and an arrest warrant was issued for Keeley out of Plymouth District Court. The warrant was entered into the National Crime Information Center.

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 investigation is being conducted by Massachusetts State Police and Marshfield Police, and is active and ongoing at this time. Anyone with information is asked to contact State Police Tpr. Cali Gately at (774) 434-5999 or Det. Tim Chiappini at (774) 380-4289.
