iStock/Thinkstock(OAKLAND, Calif.) — Searchers have recovered 24 bodies from the Oakland, California, warehouse where a fire broke out Friday night during a party, officials said Sunday.

Crews have only been able to search 20 percent of the building, so it is still feared that the death count could go much higher, according to officials.

The Oakland Fire Department responded to reports of a structure fire on 31st Avenue at around 11:32 p.m. on Friday night. Oakland Fire Chief Teresa Deloach Reed said the warehouse appears to be a work and residential building that hosts a makeshift artists’ studio. It’s unclear if the building is equipped with smoke alarms, the fire chief added.

Preliminary indications suggest the blaze was not caused by arson, but rather an electrical fire, but Alameda County Sheriff Department Sgt. Ray Kelly said the cause is still under investigation.

Investigators will look into the building’s inspection history and will try to determine whether the owner was aware what the structure was being used for. Criminal charges could be possible depending on the outcome of the investigation, the official said
