Marjorie disappeared from El Paso, Texas on February 14, 1987. She attended a Valentine's Day party at Veterans Park in the northeast part of the city. Witnesses saw a young man driving a small truck pull up at the entrance to the park and speak to Marjorie. She disappeared a short time later. Someone saw her walking in Chaparral, New Mexico on Chaparral Street, an unpaved and unlit road, at 2:00 or 3:00 a.m. the next day. Marjorie lived with her family on Byrum Street in Chaparral, a small town about 25 miles from El Paso. She has never been heard from again.

That same year, several other females disappeared from El Paso, and most of them were later found murdered and buried in the desert. The victims were all small, slender young women in their teens and early twenties. Marjorie and two other females, Melissa Alaniz and Cheryl Vasquez, are still missing.

David Leonard Wood, a serial rapist who was paroled in January 1987, was later convicted of murdering six of the El Paso victims, though he maintains his innocence to this day. He resembles the man Marjorie was seen speaking to just before her disappearance, he had lived in Chaparral off and on, and he apparently knew Marjorie slightly. He was sentenced to death in 1993, but his sentence remains under appeal, as his lawyers allege he is mentally retarded. The murders of El Paso girls and women stopped after Wood's October 1987 arrest for rape. He has not been charged in connection with Marjorie's case and it's unclear whether he was involved.

Marjorie was athletic in 1987 and enjoyed sports and horses. At least one of her friends believes she's still alive, but there is very little evidence as to her fate. Her father and one of her brothers are now deceased, and her other relatives have all moved away from Chaparral. New Mexico police are investigating Marjorie's case.
