Three firefighters are recovering from minor injuries sustained in a suspicious vacant house fire in Smithfield that's currently under investigation.
The blaze was reported around 2:30 p.m. Thursday at a home on Leland Mowry Drive in the Esmond section of town.
Fire Chief Robert Seltzer says someone ignited a fire on the porch, which worked its way into the interior of the structure by the time firefighters arrived.
Seltzer says the fire is being considered suspicious because the house was vacant and there was no power running to it.
Three firefighters were hospitalized after the blaze was extinguished. Two were treated for heat exhaustion and another was hospitalized with a bruised rib.
