Moreau was transported to the Hospital of Central Connecticut in New Britain. He succumbed to his injuries during surgery, Coney said.
"Ray was a decorated 35-year veteran of Plainville Fire Department," Coney said. "Ray volunteered tens of thousands of hours to his community. In addition to his service to the Plainville community, Ray was a loving husband and veteran of the United States Marine Corps. Firefighter Moreau was a consummate professional, dedicated servant, and will be missed dearly by his friends, family, and his community."
Residents who were in the home were able to get out, WFSB.com reported. The residents were uninjured.
Coney said the Connecticut State Police will be the primary investigation and coordinate with other state organizations and OSHA for the tragic incident.
Firefighters from Bristol and Farmington fire departments responded to the scene to assist.
"This isn't merely a job or a hobby. Being a volunteer firefighter, it is a calling, and Ray answered the call," Ronnell Higgins, commissioner of the Connecticut Department of Emergency Services and Public Protection, said during the press conference.
