The sheriff's office says detectives arrested a 19-year-old woman and a 24-year-old man Tuesday night after talking with associates of the victim.
Investigators believe the homicide occurred in Benton County, rather than Yakima County.
The coroner identified the victim as 22-year-old Preston Yahne. His family had reported him missing. He had recently returned to Prosser after four years in the Air Force. The cause of death is still under investigation.
A tow truck driver was removing the charred car from private property when he discovered a skull and bones in the trunk.
