Accused killer Nick Reiner is sitting in an 80-square-foot cell at Twin Towers Correctional Facility in downtown Los Angeles, the nation's largest mental health institution, which has been accused of unsanitary conditions, including blood-stained floors, visible mold and nonfunctioning toilets. "Inmates wake up at 5:00 a.m. and lights out is at 9:00 p.m.," Sergeant Christopher Lewis exclusively told Us Weekly about life for inmates at Twin Towers.
