Following jury trial, Woonsocket man convicted for 2016 murder

 

PROVIDENCE, R.I. – Attorney General Peter F. Neronha announced today that a Woonsocket man has been convicted of first-degree murder in Providence County Superior Court for the murder of 81-year-old Constance Gauthier in 2016. 

On January 15, 2025, following an eight-day jury trial before Superior Court Justice Maureen B. Keough, the jury found Matthew Dusseault, Jr. (age 27) guilty of one count of first-degree murder. The jury also found that the murder was committed with aggravated battery or torture thereby making the defendant eligible for a sentence of life without the possibility of parole.

The defendant is scheduled to be sentenced in Providence County Superior Court on March 28, 2025.

“Look no further than the judgment imposed by this jury to understand the severity of this defendant’s crime,” said Attorney General Neronha. “Constance Gauthier was a vibrant, active woman whose life was tragically cut short, leaving her friends and family to pick up the pieces. I can only hope that those who loved her feel a sense of closure knowing that justice has been served. I thank the Woonsocket Police Department for their partnership in the investigation of this challenging case.”

During the trial, the State proved beyond a reasonable doubt that on or about March 22, 2016, the defendant stabbed Constance Gauthier dozens of times at her residence in Woonsocket. 

On March 23, 2016, Woonsocket Police responded to Ms. Gauthier’s home after her neighbor reported seeing her lying on the bedroom floor, unresponsive, through the bedroom window. Police found the victim on the floor in a pool of blood with more than 60 stab wounds, partially concealed by a mattress. Police observed that the Ms. Gauthier’s residence appeared to have been staged as if it was ransacked, as nothing appeared to be stolen.

In July 2018, investigators submitted touch DNA samples collected from the crime scene for a genealogical review. The sample produced partial familial matches which helped lead investigators to the defendant. Prior to an interview with Woonsocket Police, the defendant consented to a buccal swab for DNA, which matched the sample collected at the crime scene.

“Violent crime will not be tolerated on our community, and I am grateful to see this defendant brought to justice,” said Woonsocket Police Chief Thomas F. Oates III. “My thanks to the men and women of the Woonsocket Police Department and the Attorney General’s Office for their tireless work in the investigation and prosecution of this case.”

Assistant Attorney General Scott Erikson of the Attorney General’s Office and Detective Anthony Conetta of the Woonsocket Police Department led the investigation and prosecution of the case.

There are reports the Justice Department is investigating Minnesota's governor and the Minneapolis mayor. Multiple outlets cite U.S. officials saying Governor Tim Walz and Mayor Jacob Frey are being investigated for allegedly obstructing federal law enforcement. One official says the investigation centers on statements the two leaders have made about the thousands of ICE and Border Patrol agents deployed to Minneapolis. Their presence has sparked protests, which have grown since the fatal shooting of Renee Good by an ICE officer last week.        Court is done for the week in the Charlie Kirk assassination case in Utah. Lawyers for Tyler Robinson, the man accused of shooting the conservative personality at a rally in September, argued a key prosecutor has a family member who was present at the time Kirk was shot. They say that communications between them raise concerns over impartiality and the prosecution's decision to seek the death penalty, and argue the prosecutor should be disqualified.        President Trump says he currently doesn't have reason to invoke the Insurrection Act in Minnesota. Before leaving the White House for Florida on Friday, Trump was asked about using the act as protests continue in Minneapolis. Trump said there's no reason to use it at this time, adding, that if he "needed it, it's available" to him. The Insurrection Act would give Trump the authority to deploy the military to suppress a rebellion on American soil.        Virginia Senate Democrats are sending a redistricting amendment to voters for approval. If voters support the amendment in a special election, which is expected to be on the spring ballot, the Legislature would be able to redraw the state's congressional map before midterms. Democrats currently have a six-five edge in the state's congressional delegation, looking to control either a ten-one or nine-two split for the new map.        Renee Good was unresponsive when first responders arrived after she was shot by an ICE agent last week in Minneapolis. A newly released incident report from the Minneapolis Fire Department offered more clarity into the incident, with Good having two apparent gunshot wounds to her right chest, one on her left forearm and another possible wound on the left side of her head. Good's killing has led to protests nationwide, while the Trump administration is calling her a "domestic terrorist."        Bad Bunny is previewing his upcoming Super Bowl halftime show performance. The video shows the singer walking through a forest while playing a song from his most recent album, soon joined by dancers off all different ages and cultures. It ends with a message saying "the world" - all different ages, races and styles - "will dance." Bad Bunny's choice as the headliner of the halftime show has drawn conservative backlash, with the Trump Administration threatening to have ICE agents at the game.
