Fifteen-year-old Robert Thomas Pillsen-Rahier, known as Robb or Bobby, disappeared from the Cheyenne Mesa residential treatment facility in Colorado Springs after a monitored phone call to his mother on the morning of July 6, 1990. During that call he hinted that something was wrong but could not elaborate; his mother went to the facility and was told he was on an off‑campus outing. Later that day the facility reported he had run away and he has not been seen or heard from since.

Descriptions at the time list him as a white male, 5 feet 9 inches, about 180 pounds, with brown hair and brown eyes. Distinguishing marks included a small scar in the middle of his forehead, scars on the last two toes of his right foot, and discolored skin on his right arm and the top of his right hand from childhood burns; he wore silver‑framed glasses with tinted lenses. Clothing reports conflict: his mother was first told he wore a blue plaid shirt and black jeans, but those items were later returned with his other belongings; both pairs of shoes he had at the facility were also returned, suggesting he may have left barefoot.

Did anyone in Colorado Springs in 1990 notice a teenage boy matching Robert’s description or have information about the Cheyenne Mesa facility around that July 6 outing?
