SALEM, Ore. --- An autopsy has found that a man who died after a struggle with Salem police suffered from a cardiac arrhythmia caused by a pre-existing heart condition.
The Marion County District Attorney's Office ruled the death as accidental on Wednesday.
Prosecutors say the Oregon State Medical Examiner found that Allen Pitts' heart condition was exacerbated by his struggle with officers.
They say the officers used an electric stun gun and wrestled with him for seven minutes before making an arrest.
Police were called to a restaurant after Pitts threatened to kill the manager and refused to leave.
Pitts stopped breathing shortly after he was handcuffed and later died at a hospital.
Oregon State Police investigated the case.
