WATERVILLE, Wash. -

The cause of death for a Waterville man who died in a struggle in July with Douglas County deputies has been determined as excited delirium.

County prosecutor and coroner Steve Clem says the determination was made last week by a contract forensic pathologist, Dr. Gina Fino.

Jason Nalls fought with deputies who had responded to a reported shooting. He jumped in patrol car and dragged a deputy about two blocks before he was handcuffed. Then deputies noticed he had stopped breathing.

The Wenatchee World reports Dr. Fino had also determined that excited delirium was the cause of death for a man who struggled with corrections officers in June in the Chelan County Regional Justice Center.

Excited delirium involves high heart and breathing rates during a period of stress.
