An Oak Park house that went up in flames late Tuesday was quickly followed by two nearby arson-caused fires, but investigators have not yet determined if the dwelling was purposely burned.
The house fire broke out about 11:45 p.m. in a vacant home in the 3700 block of Seventh Avenue, and video taken by the Sacramento Fire Department showed the house was engulfed in flames when firefighters arrived.
Firefighters poured water on the small home as smoke billowed from the front and flames licked from the roof. Other firefighters wearing breathing apparatus were partially obscured by black smoke as they hacked at the porch floor to open up access to extinguish the fire.
Nobody was injured and the cause is under investigation. The fire investigation has slowed because the burned floor of the structure is in dangerous condition.
Sacramento Fire Department spokesman Chris Harvey said two other fires were reported after crews were getting a handle on the house fire. A fire that burned a boat parked in a driveway and another fire that burned against a fence have been determined to be arson-caused.
The investigation continues into whether all three fires are related. The fires were in the same neighborhood, and all were reported within a short amount of time, Harvey said.
