"The suffocation was caused by manual occlusion of the mouth, in concert with forced inhalation of ammonia fumes that caused spasm of the vocal cords resulting in internal blockage of the upper airway."

It is expected that the guards will be charged in Anderson's death. The camp has since been closed. More details:

Anderson collapsed January 5 at the Bay County Sheriff's Office Boot Camp program in Panama City, Florida. He had complained earlier in the day, his first at the facility, of breathing difficulties while running around a track as part of the admission process.

At one point, Anderson told the officers he couldn't breathe well enough to continue running. The report said he resisted repeated attempts to get him to complete the exercise by pulling away, tensing his body, struggling and balling his fists.

Videotape of the incident showed Anderson being forced to the ground by various takedown methods, including knee strikes to his thigh, pressure points to his ear and punches to his arms. Later, another camp staffer hit him from behind, forcing Anderson to lurch forward. A nurse stood by, and on at least one occasion she determined his vital signs were normal. Anderson was taken away on a stretcher and died later that day.
