When Natasha McKenna was in police custody at the Fairfax County, Virginia, jail in February, the mentally ill woman was restrained by six deputies who, unable to subdue her, shocked her with a Taser. She died several days later. But as the Washington Post reported recently, when the Virginia medical examiner’s office ruled on the cause of death, the conclusion was that a rare and mysterious syndrome known as “excited delirium” had actually killed her, and not the Taser or the extreme force used by six officers against a woman suffering from schizophrenia and bipolar disorder who weighed just 130 pounds.
