Authorities say the area where the fire started was full of electronic equipment, including radio and stereo equipment, all plugged into one outlet via a power strip. It’s unclear though, which particular piece of equipment malfunctioned to cause the fire. Several devices melted together. Investigators called the blaze accidental.

Ceballos was not related to the homeowner, Mary Brown, and did not live at the residence. The woman was an acquaintance of one of Brown’s family members who was not at the house at the time of the fire. Brown and a relative escaped the fire uninjured. A 71-year-old man in the house was treated and released at a Council Bluffs hospital.
