PULLMAN, Wash. -

An autopsy shows that a seizure was ultimately to blame for the death of a Washington State University professor.

Scott Stratton was found dead in a pond at Sunnyside Park in Pullman last week.

The Moscow-Pullman Daily News says Stratton had a history of seizures.

Whitman County Coroner Pete Martin says Stratton had been off his medication for about 10 days at the time of his death, because the medication was causing a rash.

Martin says the cause of death was drowning in just 2 feet of water, because Stratton fell into the pond rather than on solid ground when he had a seizure.
