Oklahoma City police clear paramedics involved in what they called a "suspicious" death.
Jason Marshall, 42, died at the hospital after being transported from the downtown Oklahoma City bus station.
The Medical Examiner's office ruled Marshall died of natural causes, but that was questioned by one firefighter at the scene.
Records show Marshall bit a paramedic and kicked and scratched a firefighter. Paramedics allegedly put him in a chokehold and hit him in the face before allegedly using a spray to cause him to pass out.
