The outrageous allegations were made in a report which claims the incident happened more than 20 years ago. And the couple say they have been troubled ever since over what may have happened to the "kidnap victim".
The woman has reported her claims to the US-based Mutual UFO Network (MUFON), which investigates suspected UFO and alien cases, in the hope she can discover what happened to the man who she claims first approached her at an auto garage in Casa Grande, Arizona, in around 1995.
The "missing man" claimed to have obtained video from Area 51, which proved dead aliens were stored there in the Nevada desert, according to the report.
According to conspiracy theorists the mysterious US Air Force base Area 51 is where evidence of alien visitations, including dead bodies from the alleged Roswell flying saucer crash of 1947, is hidden away.
