I just joined up today -- specifically for the Caylee Anthony case. I now live in Orlando, but I am from Maryland (Bowie).
I was surprised to see threads on the Lyon girls. It has been so long. They disappeared in 1975, just after I started dating my husband. My husband has several younger sisters who are blonde and about the same ages as the Lyon girls. Shortly after the disappearance, my father-in-law was pulled over by the police. He was driving with a couple of my sisters-in-law in the car, and the police wanted to be sure they were not the Lyon girls.
We have never forgotten those girls. It's nice to see that others remember them, too.
