Adam Castonguay, 43, was found unconscious with a gunshot wound to the chest at a Village Road residence in Woonsocket, Rhode Island, in the early morning hours of April 15, 2021, and was pronounced dead at the scene. The death was initially treated as a homicide and quickly became a domestic investigation.

Authorities identified Castonguay’s 22-year-old son, Alex Cote, as the primary suspect; Cote fled on foot but was located and taken into custody in Pawtucket later that same day. He was charged with domestic homicide, discharging a firearm during a crime of violence, and possession of a firearm without a permit. The case went to a jury-waived trial in October, where the defense said the shooting occurred during a physical altercation and that Cote fired after Castonguay was choking him. The judge found Cote had been in danger of death or imminent serious bodily harm and ruled he acted in self-defense, leading to acquittal on the murder charge.

Anyone who knew Adam Castonguay or witnessed events at the Village Road residence on April 15, 2021, is asked to share information.
