Human remains discovered in Lower Valley could be Prosser man

SUNNYSIDE, Wash. -- An investigation is underway after human remains were discovered in the Sunnyside area. Deputies said the bones were found in a car that belongs to a missing Prosser man.

A tow company was removing the burned out car from a property at Emerald and South Emerald Roads. The truck operator told deputies he found what appeared to be a skull in the trunk.

The registered owner is Preston Yahne who was reported missing last weekend.

The remains have not been positively identified. They will be sent to Seattle later this week for further examination.
