Man arraigned for brutal double murder of married couple

A 28-year-old man, Christopher Keeley, has been arraigned in Brocton Superior Court on charges of violently killing a married couple in their Marshfield home. Keeley faces two counts of murder for the deaths of 70-year-olds Carl and Vicki Mattson. He pleaded not guilty to the charges he’s facing, and he is currently being held without bail.

The case unfolded when Marshfield Police received a call on November 26, 2022, from an acquaintance of Keeley’s, who requested a well-being check on him at a residence located at 75 Gotham Hill Drive. Upon arrival, officers found the home quiet, with no car in the driveway and no sign of Keeley. After contacting a family member of the Mattsons, the police learned that Keeley had not lived at the residence for some time.

Three days later, on November 29, 2022, Marshfield Police returned to the Gotham Hill address after a well-being check was requested for Carl and Vicki Mattson. Upon arrival, officers discovered the couple’s lifeless bodies with clear signs of having been bludgeoned and stabbed.

The Massachusetts State Police Detective Unit launched an investigation. Detectives gathered sufficient evidence to identify Keeley as a person of interest in the couple’s murder. Police subsequently issued a warrant for his arrest.

A Be-On-the-Look-Out (BOLO) alert was issued for Keeley by the Massachusetts State Police Commonwealth Fusion Center, along with a description of a 2019 black Jeep Wrangler. The Jeep was later found unoccupied in an Avon parking lot and secured by investigators.

In an unrelated incident, Keeley was taken into custody in Florida on December 2, 2022. Authorities in Florida collaborated with Massachusetts State Police to detain Keeley on the Massachusetts warrant that two counts of murder.

He is scheduled to appear in Plymouth Superior Court again on June 29.
