The Vermont State Police is investigating the death of an inmate at the Southern State Correctional Facility in Springfield.

State police say Charles Mould, 74, of Bennington was found unresponsive in his cell by Department of Corrections staff at about 3:20 AM Wednesday, Nov. 30. DOC staff called for emergency medical services to respond to the facility. Mould was pronounced deceased at the facility at about 3:38 AM.

Detectives from the Vermont State Police Bureau of Criminal Investigations were notified and responded to the facility to perform a death investigation. The preliminary investigation does not indicate that the death is suspicious. An autopsy will be performed at the Vermont Chief Medical Examiner’s Office in Burlington to determine the cause and manner of death.

Mould has been in custody of the Department of Corrections since 2008 and was serving a sentence of 40 years to life on charges that included aggravated sexual assault-repeated, aggravated sexual assault on a victim less than 10 years old, and lewd and lascivious conduct with a child. He was housed in the infirmary unit at the time of his death.

A 2008 Bennington Banner news account said Mould had been accused of 40 sex crimes and was reportedly non-compliant in his required sex offender treatment.
