The fire was quickly contained by firefighters, who had to deploy six fire engines to extinguish the blaze. The fire burned approximately 1-acre of hillside.

While firefighters were battling the fire, numerous police officers scoured the area and located a woman matching the witnesses’ descriptions. She admitted to setting the fire, then proceeded to kick one of the officers in the shin when officers attempted to detain her in handcuffs.

During the fire investigation, another officer was conducting an investigation of a grand theft and extortion case. The officer determined the woman detained for setting the fire was also the outstanding suspect in his investigation.
