City police on Wednesday said they took Tyler Grenon and Matthew N. Dusseault into custody in connection with the murder of Constance Gauthier.
Gauthier, 81, was found dead inside her Fairfield Avenue home on March 23, 2016.
Grenon was initially arrested on non-murder charges related to the investigation a week after her death. His father, Gauthier's neighbor, told Eyewitness News it was Tyler who alerted police to Gauthier's death. He said his son was worried about Gauthier and looked in her window, spotting her underneath a mattress with the room ransacked. Police never confirmed that series of events.
Police were seen searching Grenon's home and yard the day after Gauthier was discovered. They brought his son in for questioning after two of Gauthier's neighbors said he demanded copies of their home security camera footage.
At that time, investigators said they believed those responsible for the killing knew Gauthier.
"It was a personal attack, I would definitely say that," Detective Lt. Brad Scully said.
A lifelong resident of Woonsocket, Gauthier worked for the school department and was a member of the city's personnel board. Friends of hers said she was an animal lover and very active for her age.
Grenon, 23, of Attleboro, and Dusseault, 20, of Woonsocket, were both charged with first-degree murder and conspiracy charges. Both men were arraigned in court Wednesday and ordered held without bail.
Grenon's attorney offered no comment outside court but Dusseault's said his client has a clean record and maintains his innocence.
Both men are due back in court August 1.
