Robert Pillsen-Rahier

On July 6, 1990, fifteen-year-old Robert Pillsen-Rahier was last seen in Colorado Springs, Colorado. 

At the time of his disappearance, he was residing at Cheyenne Mesa, a day program and residential treatment facility for adolescents with psychiatric & behavior problems. The facility closed down in 1997 due to financial insolvency.

Robert was having behavioral and emotional problems after witnessing his stepfather commit suicide when he was seven years old. The morning he went missing, he called his mom and insinuated that something was wrong, but he couldn't say what it was because his phone call was being monitored.

Robert's mom called Cheyenne Mesa to make arrangements to visit him, but the staff told her that Robert was on an outing. Later that day, an employee at the facility told Robert's mom that he ran away.

A week before his disappearance while he was on a weekend home visit, Robert's mom discovered blood on his underwear while washing his laundry. She suspects that Robert might have been sexually abused while he was at Cheyenne Mesa.

As of 2023, Robert is still missing.
