Bouncing Back


We have just received new information on this unsolved, highprofile case from several years ago. On May 6, 2000, the wife of billionaire oil tycoon Donald Holloway drove away in her car and never returned. As we never found any evidence of foul play, we believed that Mrs. Holloway left her husband and changed her identity. Recently, Mrs. Holloway’s California vanity license plate, OIL GIRL, was found outside a remote gas station along the Desert Highway. This particular gas station happens to be quite close to lands owned by the Holloway oil empire. Also uncovered in recent weeks have been several documents detailing the purchase of some large properties along the road. It now looks like Holloway may have killed his wife and buried her and her car at one of the properties.
