June 10, 2026

Plymouth County MA-The legal proceedings against Christopher Keeley, the man charged in the 2022 deaths of Carl and Vicki Mattson of Marshfield, remain ongoing within the Plymouth County Superior Court system.

Current Status

Keeley continues to be held without bail. The case is currently moving through the standard, often lengthy, pre-trial phase typical of major felony litigation in Superior Court. This stage involves an extensive exchange of discovery evidence and ongoing motion practice between the prosecution, led by Assistant District Attorney Amanda Fowle, and the defense.

At this time, there have been no public announcements regarding a firm trial start date or significant new developments in the proceedings.

Case Background

The investigation into the tragic incident at 75 Gotham Hill Drive in November 2022 resulted in Keeley’s indictment on several serious felony charges:

• Two counts of murder (for the deaths of Carl and Vicki Mattson, both 70).
• One count of animal cruelty (in connection with the killing of the couple’s dog).
• One count of larceny of a motor vehicle.
• One count of misuse of a credit card.

After being taken into custody in Miami Beach, Florida, in December 2022 and subsequently extradited to Massachusetts, Keeley entered a plea of not guilty to all charges. The matter remains under the jurisdiction of the Plymouth County District Attorney’s Office as it navigates the administrative and legal requirements of the Commonwealth’s court system.
