The search of the warehouse is over and the number of those killed in the Oakland fire stands at 36.

FOX's Jessica Rosenthal reports:

Fire officials say they have searched the entire warehouse and no more victims have been found. They were still searching for evidence though and trying preserve it as part of the criminal investigation into the fire.

The ATF is exploring what caused the fire and a special agent in charge said it did not appear to be intentionally set. They were investigating if it was electrical.

Public documents show complaints about this property date back to roughly 2004, specifically complaints of trash and debris and old cars.

The most recent one about trash and debris was filed last month. Another complaint was that there was illegal interior building going on on the property.
