Rhode Island Man Stabbed Elderly Neighbor 60 Times

In a case that has haunted the community of Woonsocket, Rhode Island, for nearly a decade, justice has finally been served. On November 18, 2025, Matthew Dusseault, 28, was sentenced to life in prison with the possibility of parole for the brutal 2016 murder of his elderly neighbor, 81-year-old Constance Gauthier. The chilling details of the crime and the long road to conviction reveal a story of horror, heartbreak, and the relentless pursuit of justice.

A Home Turned Crime Scene

Constance Gauthier was found dead in her own home on March 23, 2016, in a scene that shocked even seasoned investigators. Her body was discovered beneath a mattress in her bedroom. She had suffered more than 60 stab wounds. The savagery of the attack was staggering. The fact that her body was hidden under a mattress added a grim layer of cruelty to the crime.

What made the case even more perplexing was the state of Gauthier’s home. Police noted that the residence appeared to have been staged to look ransacked, yet nothing was actually stolen. This bizarre detail suggested a motive beyond robbery, deepening the mystery surrounding the attack.

The DNA Trail That Led to Conviction

For years, the case remained unsolved, leaving Gauthier’s family and the community searching for answers. The breakthrough came through forensic science. DNA samples collected at the crime scene were subjected to genealogical analysis, which eventually led investigators to Matthew Dusseault. A buccal swab taken from Dusseault matched the DNA found in Gauthier’s bedroom, providing the crucial link needed to charge him with first-degree murder.

Despite the overwhelming evidence, Dusseault maintained his innocence throughout the trial and sentencing. He reortedly expressed frustration over being labeled a criminal and questioned the justice of his conviction, highlighting the emotional complexity that often accompanies such cases.

The Impact on Family and Community

The sentencing brought a measure of closure to Gauthier’s family, though the pain of her loss remains palpable. Her niece, Sandy Paul, spoke about the brutality of the crime and the void left by Gauthier’s absence, emphasizing that no sentence could fully compensate for the life taken. “It’ll never be enough. She’s not here,” Paul said, as reported by PEOPLE.

Attorney General Peter Neronha described Gauthier as a “vibrant, active woman whose life was tragically cut short,” as reported by PEOPLE. He expressed hope that the conviction would bring some peace to those who loved her and underscored the commitment of law enforcement to pursuing justice in violent crimes.

Reflecting on a Senseless Act of Violence

This case serves as a stark reminder of how quickly a safe and familiar environment can become the setting for unimaginable violence. The fact that Gauthier’s home was turned into a crime scene, with her body concealed in such a disturbing manner, adds a layer of horror that resonates deeply with anyone who values the sanctity of home and safety.

For nearly a decade, the community grappled with the fear and uncertainty that such a brutal crime instills. The eventual conviction of Matthew Dusseault not only holds him accountable but also reaffirms the power of forensic science and the justice system to bring resolution, even in the most harrowing cases.

Closing Thoughts

The sentencing of Matthew Dusseault closes a dark chapter in Woonsocket’s history but leaves a lasting impact on all who followed the case. It is a sobering example of the depths of human cruelty but also a testament to the resilience of a community seeking justice. As you reflect on this story, consider the fragility of life and the importance of justice in healing wounds that violence leaves behind.

Justice may not erase the horror, but it offers a path forward - a reminder that even in the darkest moments, accountability matters.
