The 55-year-old veteran Alaska Airlines pilot found dead on a 5 Freeway offramp in Burbank in October died of natural causes, authorities said Thursday.
The man — Lee Morris of Richland, Wash. — died of atherosclerotic heart disease, said Los Angeles County Coroner spokesman Craig Harvey. The disease results in a build-up of plaque in the arteries.
Morris had no external injuries and there was no indication of foul play, Harvey said.
The 26-year pilot had passed regular physical check-ups and appeared to be in good health, Alaska Airlines spokesman Paul McElroy said shortly after Morris’ death.
All Alaska Airline captains undergo a physical exam twice a year, he added.
But according to the National Heart Lung and Blood Institute, some people who have atherosclerosis have no signs or symptoms and may not be diagnosed until after a heart attack or stroke.
Burbank police had no other details Thursday on why Morris was walking near the freeway.
