The Benton County coroner said no foul play is suspected in the death of a 28-year-old Kennewick man found last weekend at his home in the Finley area.

But why Austin Shawn Ariss died could not be determined from the autopsy this week and will have to wait for the return of lab tests in several weeks, said Coroner John Hansens.

Ariss, a Tri-City native, worked as a hydroelectric rewinder on dams.
