The National Association of Medical Examiners created a database on Taser-related deaths to provide guidance to medical examiners on how to rule in deaths linked to the use of stun guns.

“It?s just an effort to look at case reports, newspaper stories, whatever is out there and try to formulate some opinions as to what we need to do,” said Dr. Randy Hanzlick, chief medical examiner in Fulton County, Ga., and one of the database?s primary architects. “There are so many factors involved in some of these deaths ? usually there is another explanation, but to cast off all doubts doesn?t make sense.”
