Sunday house fire is ruled arson

A house fire Sunday morning in the 3400 block of Chadbourne Street was deliberately set, Richmond County sheriff’s investigators say.

Firefighters arrived at the vacant house around 7:30 a.m., and investigators determined that both the front and back doors had been forced open.

Electrical power was on at the house, but there was no evidence that it was the source of the fire, which was mainly contained to a rear bedroom, a report says.

The investigation is ongoing.
