The space was hosting a 100% Silk party with a performance by house artist Golden Donna. Many of the dead were reportedly trapped on the second floor.

“There wasn’t a clear entry or exit path up on the second floor. … If (the fire) had started in that area (by the stairwell), then everyone on the second floor” would have had trouble escaping, Oakland Fire Chief Teresa Deloach Reed said, via CNN.
