OAKLAND (KRON) — Alameda County Sheriff Gregory Ahern announced late Monday afternoon that he’s hopeful no more dead bodies will be found at the site of the deadly warehouse fire in Oakland’s Fruitvale District Friday night.

Ahern said there are “still two areas of concern” they have not searched yet because of safety issues.

As of Tuesday morning, 26 families have been notified and there are still 9 tentative IDs. One victim, a male, has yet to be identified.

Some of those deceased are from Korea, Finland and Guatemala. Those identities that have not been released included a 17-year-old, sheriff officials said.

Alameda County District Attorney Nancy O’Malley said Monday her office has just started its probe and has not yet determined whether a crime even occurred. Charges could range from murder to involuntary manslaughter. The office is working with the city of Oakland to make sure the information they give out to the public does not compromise the investigation.

“It’s too early to speculate on anything,” O’Malley said. “We just started our investigation, and we owe it to the community and those who perished in this fire, and those who survived the fire to be methodical, to be thorough, and to take the amount of time it takes to be able to look at every piece of potential evidence.”

ATF officials have been critical in collecting evidence from the scene, said Oakland Mayor Libby Schaaf. Other public service officials have also been working to also make sure the scene has not been compromised.

“Today is the day two dozen families are going to learn the loss of their loved ones,” she said. “Today is the day nearly two dozen families are going to start an entirely new life.”

Oakland planning officials opened an investigation in November after complaints from people living nearby about the warehouse. An inspector who went to the building couldn’t get inside. Schaaf said city officials are putting together a record of what they knew about the “Ghost Ship” warehouse. The property’s manager Derick Ion Almena was confronted several times by city officials about trash in front of the warehouse and in the street, according to Oakland city councilman Noel Gallo.

Recovery efforts were stopped Monday morning because of stability concerns of the building. Crews have searched about 75 percent of the building. PG&E shut down power for almost 12 hours in the area as they continue their investigation. Less than 10 residents have been impacted, said Oakland police spokeswoman Johanna Watson.

About 50 people have still not been accounted for following the fire, but it has not been determined if they attended the event, according to sheriff’s officials. The community has been reaching out to the office about information they know about the fire. O’Malley said the county has set up a hotline for people to provide additional information at (877) 288-2882. Victims and their families also have a hotline where they can receive support at (510) 272-6180.

Schaaf encouraged people to donate money to victims and their families The Oakland Raiders, Oakland Athletics and Golden State Warriors have donated $50,000 each to the victims.A separate crowdfunding website YouCaring has collected about $294,000.
