Derrel Sims, known as "The Alien Hunter," discussed the physical evidence for alien abduction with Art Bell, who is now hosting the show the last two Sundays of the month. Sims revealed that he is an abductee himself, with episodes involving white, bulbous-head "entities" dating back to when he was only 3 years old. During this first encounter he believes that both the fear and paralysis he experienced may have been "installed" by the entity through its large black eyes.

During an abduction at age 12, he said a long needle-like device with a small ball on the end was placed far into his nasal passage in order to deposit an implant. Sims has studied implants from a number of abductees and in a recent "mass abduction" case in Houston, involving eight witnesses, he noted that a woman had an implant placed in her eye. Spots of fluorescence have also been found on abductees, and will show up within 24 hours, if they have been handled by the entities, he shared, describing it as a kind of "alien sweat."

Rather than trying to add something to human genetic stock, Sims suggested that the abductors may be trying breed things "out of our lineage." He also views the abductions as the "psychological and spiritual rape of an individual," conducted for the purpose of instilling terror.
