RICHLAND -- A West Richland teen whose body was found Saturday morning in Benton County died after falling from a grain silo.

Benton County Coroner John Hansens said an autopsy showed Austin Everette Katayama, 18, died from injuries from the fall.

His death is not believed to be an accident but no foul play is suspected.

Hansens said he doesn't know what time Katayama fell, but said Benton County sheriff's deputies were called at 9:47 a.m. when a motorist spotted the body near the silo on South Badger Canyon Road near Sellards Road.

The autopsy was performed Monday by Dr. Carl Wigren, a forensic pathologist from the Seattle area.
