Sprawled on the concrete floor of a jail cell in LaSalle Parish, Jaleen Anderson could do little more than wave at an overhead surveillance camera for help. Over the prior 36 hours, the 29-year-old had experienced a series of at least six seizures, at times covering his bed in urine and his cell in vomit, his family says. After Anderson’s fourth, guards found him on the floor, seemingly unable to stand, and sought permission to call an ambulance for him.
