1. The ‘Brutal Murders’ Occurred in the Couple’s Home
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,” a November 30, 2022, news release stated.
The search was announced by Plymouth County District Attorney Timothy J. Cruz and Marshfield Police Chief Phillip A. Tavares.
Last evening at 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.”
After an investigation, detectives developed probable cause and identified Christopher Keeley, 27, of Weymouth, as a person of interest in the double homicide, officials said in the press release.
2. A Barking Dog Was the Motive, Police Say
Kristin Robinson wrote on Facebook that the Mattsons’ dog was missing.
Thank you everyone for reaching out. Sorry I can’t answer you all, but I feel the love that you all had for my mom and dad. My parents’ dog Bailey is still missing, if anyone has seen him around Marshfield please reach out to me. It is quite possible he could be in Avon as well. To anyone who lives on Gotham Hill and the surrounding area, please check under your decks/porches.
According to court documents obtained by CBS News, there was evidence in the home of a struggle, including an “overturned bookcase.”
Investigators believe the killings occurred the previous week. A friend asked police to check on the Mattsons, according to CBS. The news station reported that Keeley “had been living with the couple as a favor to a family member, but had recently been asked to leave.”
An argument “over a barking dog” provoked the killings, according to what Keeley told a friend, CBS News reported. Keeley was described by CBS as acting “psychotic” and telling a friend he carried knives and had “an urge to hurt people.” He “was angry and fearful he would end up homeless after a woman who had considered letting Keeley stay with her in Weymouth threw him out,” CBS News reported.
3. Police Sought & Then Located a 2019 Black Jeep Wrangler
The Massachusetts State Police Commonwealth Fusion Center issued a BOLO alert for Keeley and a 2019 black Jeep Wrangler, the news release stated. Investigators recovered and secured the Jeep this afternoon at a parking lot in Avon. The motor vehicle was unoccupied.
Search warrants were executed and an arrest warrant was issued for Keeley. “Preliminarily, this does not appear to be a random act of violence,” the release said.
4. The District Attorney Called the Murders a ‘Targeted Attack’
Authorities say the murders were not random.
“This appears to be a targeted attack against these two individuals,” Cruz told reporters at a news conference.
“The individual that we are looking for right now, we consider him armed and dangerous.”
5. People Expressed Grief & Shock on Social Media
Robinson wrote of her parents, “My rocks! Always there to support me and encourage me to do great things. I am who I am today because of them. I love you guys – you will be with me in my heart forever ❤️”
A woman responded,
I am so sorry for your loss Kristen, your Mom was an amazing lady and a good friend. I have many wonderful memories of our time together that I will hold close to my heart. May your Mom and Dad rest in the sweetest peace and may God cover you and your family with His loving comfort.
“Please bring Justice to my friends. So viciously murdered,” a friend wrote on Facebook.
