Right after I joined the State Police, we had a 15 year old male runaway. This was back in the early 70’s when we had very little technology to help us find missing children. In fact, we had zero technology and had to rely on pictures and word of mouth. Hopefully, if a cop stopped a kid for any one of a hundred different reasons and checked him out, maybe we would discover him or her to be a runaway.
He he finally called home some 30+ years later. It just so happens that the county fair was going on at the time of his runaway, which hired a carney group to run the rides and midway shows. The boy, who was a bit tall for his age was able to join the carney guys and get himself a job. At the time of his call home 30+ years later, he was in Oregon. He never did come back to see his parents, but we were able to verify his identity with the aide of the Oregon State Police.
What was sometimes thought to be a runaway child turned out to be a kidnapping and murder by a stranger. Worse than that, we have since learned that many of the “supposed” runaways were murdered children committed by the parent or parents.
