Andrea Lynn Unger Augsburger, 19, of McAllen, Texas, was last seen on November 29, 1999. Concerns arose early that she might have traveled to Mexico, but her family says her sudden and complete lack of contact led them to suspect foul play. Authorities have also considered that she may have been taken against her will shortly after she was last seen.

Andrea is described as a Caucasian female, blonde hair, blue eyes, between 5 feet 6 inches and 5 feet 7 inches tall, and weighing about 120 to 130 pounds. She may have used aliases including Andrea Lynn Hinojosa and Rachel Stopar. Despite various leads, she has never been located and the investigation remains open.

Did anyone in the McAllen area around late November 1999 know Andrea, her movements, or any of the names she may have used?
