The Humboldt County Sheriff’s Office in California has announced a $20,000 reward in the case of Andrea “Chick” White, a Native American woman who has been missing since 1991.

Andrea White was last seen on July 31, 1991, along Highway 299, near the Blue Lake off-ramp in Humboldt County, as reported by FOX 10. At the time of her disappearance, she was 22 years old.

The reward includes $5,000 from the Bureau of Indian Affairs Missing and Murdered Unit and an additional $15,000 from the Hoopa Valley Tribe, reflecting a combined effort to seek information on her whereabouts.

Authorities have indicated that White might have accepted a ride in a “white over green 1964 Chevy Impala four-door” equipped with mud/snow tires on the rear. This event reportedly occurred around 1:30 p.m. on the day she was last seen.

Andrea White is described as being 5 feet tall, weighing approximately 115 pounds, with brown hair and brown eyes.
