"Derek and Micah screaming at each other," she said.
Defendant Derek Almena calmly listened as she described fears about fire safety.
Turner said, "The electric-everything was run on extension cords, run on the ceiling. There were a lot of flammable materials. These junk piles upstairs with more wood scraps. I started sleeping in the car so I didn't have to go inside the warehouse."
Tony Serra, Derek Almena's attorney, said, "She doesn't know anything about what the facility was and the noise level was in 2016 at the time of the fire. Maybe she's not a very credible person. There's information she was using another person's ID and credit card."

Next on the stand was sculptor Jose Avalos who lived inside an RV inside the ghost ship for two years and stored his flammable art supplies there.
Tyler Smith, Max Harris' attorney, said, "He and Max were friends, still are friends. Jose was there that night."
In fact Avalos talked to ABC7 News right after the fire.
