Fire investigators are looking into the cause of a suspicious fire that erupted Monday in a Los Osos home destroying it and badly burning the male resident.

According to a news account by KSBY-TV, the fire was reported at 3:45 p.m. Monday, Feb. 8 in a home at the corner of Woodland Drive and Broderson Avenue, by a neighbor from across the street. When Sheriff’s deputies and firefighters from the South Bay Station arrive, the flames had burst through the roof and were starting to catch trees on fire. A power line reportedly came down and was sparking along the ground, too.

The neighbor said she had spoken with the resident of the home just a half hour before smelling smoke and running outside where she saw the fire and called for help.

The resident, identified as Mark Hannah, 47, had been the subject of a “check the welfare” request by family members earlier that same day, as they were concerned about his mental state, the report said. Sheriff’s deputies stopped his vehicle in Cayucos earlier, spoke to him and then released him. Hours later, the house went up in flames, and Hannah was reportedly inside when the blaze started.

The news report said he was found in the backyard during the blaze, suffering third degree burns on 30% of his body. He was rushed to a burn unit in Fresno, and was reportedly under arrest. The home was a total loss.

A local resident, Hunter Kilpatrick was on scene and took a series of dramatic photographs, some of which are used here. Here’s a link to Kilpatrick’s Facebook Page with a slide show of 38 photos.
