Ghost Ship master tenant Derick Almena and his second-in-command, Max Harris, were arrested Monday and charged with 36 counts of involuntary manslaughter in conjunction with the Dec. 2 Ghost Ship fire that killed three dozen people. Alameda County prosecutors found the pair hoarded flammable materials from floor to ceiling in the warehouse, created an illegal party space, and even blocked one of only two exits from the second floor the night of the fatal fire. “The paying guests at the event were faced with a nearly impossible labyrinth of the defendants’ making to get out of that building,” said District Attorney Nancy O’Malley at a news conference Monday.
