Surveillance video of Gotbaum's last moments at Phoenix airport

After displaying some agitation (somewhat physical with others), Carole Anne Gotbaum was subdued:

The witnesses that saw her just before she went into the holding tank say she was completely listless and unconscious," said [family attorney] Manning.

She was cuffed to a bench in the cell and found dead after some time. The initial explanation from the police was that she had strangled herself with the chain on the cuffs.
