LAKE CITY, Fla.  —  A man died Thursday after deputies stunned him with a Taser after he jumped from an ambulance, authorities said.

A friend of Ashley Ryan Stephens called 911 to request an ambulance, saying her friend was a drug user and was sick. A deputy was sent along with the ambulance crew, which is standard procedure if drugs are involved, said Columbia County Sheriff Bill Gootee.

Once inside the ambulance, Stephens became agitated and combative and kicked out an ambulance window. When the ambulance stopped, Stephens jumped out and ran into the street. He was nearly hit by several cars, Gootee said.

Stephens was stunned twice and handcuffed. He was pronounced dead at the hospital.

An autopsy is scheduled for Friday.
