A federal team arrived Friday to start creating a 3-D map of the fire. They're made up mostly of electrical engineers who will try to track the exact cause of the fire.
ABC7 sister station KGO-TV learned fire inspections weren't done at the warehouse for at least a decade.
On Thursday, Angel Colon paid respects to the 36 victims lost in the blaze. He was shot six times during the Orlando nightclub massacre. He knows the tragedies are different, but said support helped get him through.
"It was very overwhelming with the love, now it's my turn to do the same," Colon said.
People also gathered at Oakland's Youth Radio last night to grieve and comfort each other. It was a night of reflection for the arts community, a number of people there knew the fire victims.
