NBCRightNow.com - The Yakima County Sheriff's Office is investigating what they are calling a possible homicide in the Sunnyside/Grandview area.
Deputies say on Tuesday a tow company was removing a burned out car from private property along Emerald Rd. While loading the car on to a tow truck, the driver noticed what he thought was a human skull in the car's trunk.
Investigators later found the car registered to Preston Yahne, 22, who family members reported missing out of Prosser on June 16th.
On Wednesday the human remains were given to the Yakima County Coroner for further investigation. The remains have not been positively identified and a cause of death has not yet been determined.
