OAKLAND — The master tenant of a San Francisco Bay Area warehouse where 36 people perished when a fire ignited during a 2016 dance party pleaded guilty Friday to the deaths, avoiding a second trial after the first ended in a hung jury.

Derick Almena, 50, pleaded guilty to 36 counts of involuntary manslaughter in exchange for a 12-year sentence. Already free on bail, Almena likely won’t return to jail because of the nearly three years he already spent behind bars and credit for good behavior.

Alameda County Superior Court Judge Trina Thompson read each count with the name of the victim. When she asked Almena his plea for each charge, he answered “guilty,” but his quiet responses were sometimes inaudible through an online stream of the hearing held virtually because of the coronavirus pandemic.

Thompson scheduled sentencing for March 8, when she will determine whether he will pay restitution, continue to be monitored electronically at his home in rural Northern California and be subject to supervised probation. Families of the victims will be allowed to give victim impact statements at that time.

Alameda County prosecutors say Almena was criminally negligent when he converted the industrial Oakland warehouse into a residence and event space for artists dubbed the “Ghost Ship,” stuffing the two-story building with flammable materials, extension cords. It had no smoke detectors or sprinklers.

The Dec. 2, 2016, fire broke out at the warehouse during an electronic music and dance party, moving so quickly that victims were trapped on the illegally constructed second floor. Prosecutors said the victims received no warning and had little chance to escape down a narrow, ramshackle staircase.

Almena Had Been Jailed Since 2017 Until He Was Released in May

The case has been emotionally wrenching for family and friends of the victims, many who packed a courtroom for months in 2019, only to see a jury split on whether to convict Almena, who leased the building. The jury also found co-defendant Max Harris, who was the Ghost Ship’s “creative director” and would collect rent, not guilty at the same trial.

Colleen Dolan, mother of victim Chelsea Faith Dolan, told the East Bay Times that families were not informed of the plea deal possibility before last Wednesday.

“My heart dropped, especially when I heard it was going to be a slap on the wrist. I want my daughter back; we want to be with our family members who died. He gets to be with his family,” she said.

Almena had been jailed since 2017 until he was released in May because of coronavirus concerns and after posting a $150,000 bail bond. He is on house arrest with an ankle monitor in the city of Upper Lake, where he lives with his wife and children.
