Details of Disappearance

Pillsen-Rahier was last seen at approximately 8:45 a.m. on July 6, 1990 in the vicinity of the 13500 block of south 8th Street in Colorado Springs, Colorado. He was staying at the now-defunct Cheyenne Mesa, a treatment facility for adolescents with mental and emotional problems.

That morning, Pillsen-Rahier called his mother and insinuated that something was wrong, but told her he could not say exactly what was troubling him because the call was being monitored. His mother immediately called the facility to make arrangements to visit him, but was told that Pillsen-Rahier was on an outing. Later the day, a Cheyenne Mesa employee told Pillsen-Rahier's mother he had run away. He has never been heard from again.


Authorities are not certain what happened to Pillsen-Rahier. He has no history of running away and his mother does not believe he ran away. She stated that even if he had, it would be highly unusual for him to have no contact with his loved ones for this long. Pillsen-Rahier's mother had a close relationship with her son at the time he went missing. There is no evidence of foul play in his disappearance. His case was reclassified to a runaway to endangered missing several years after his disappearance; it remains unsolved.
