The female, a passenger in a tractor trailer, was killed in a fiery crash on Interstate 5, near Kalama on May 14, 1991. The driver, also killed, was identified.

Based on the driver's history, she may have been picked up along his route as a hitchhiker, between the states Missouri and Washington.

She was buried as Jane Doe in Longview. Her body was exhumed in January 2014 in order to obtain a DNA sample and to create a reconstruction of what she may have looked like.

The remains were later examined further and the woman is now believed to have been of Native American ancestry, prompting an updated facial reconstruction to be created.

She is known to investigators by the nickname "Helen Doe."
