Vermont State Police say the inmate found dead in his cell at Southern State Correctional in Springfield on Sunday likely took his own life.

Dennis Mayotte, 37, of North Springfield was found dead shortly before 2 p.m. Sunday. An autopsy in Burlington will verify the cause of Mayotte’s death, but Vermont State Police say it appears he took his own life.

Mayotte had been in police custody since October 24, when he was arrested on charges of first-degree arson for allegedly attempting to burn down Gouger’s Market & Deli.

He is the sixth inmate at Southern State Correctional to die in custody this year and the twelfth to die in custody in the last two years. .
