I also have Nancy Kirkpatrick on the list.
Kathy Guerrrera, 16, disappeared from her home in Missoula (August '74).
It's very possible that some of these girls were runaways, and that they later returned home. I just was unable to find anything further on them.
Kathy Guerrera was a childhood friend of mine. She disappeared and none of us knew where she had gone or what happened. She showed back up in Missoula many years later. She had run away and been living back East with an older man. She is alive and well and back in Missoula I can say with certainty because I did catch sight of her as recently as a few weeks ago. Robyn Pettinato was a cousin of some friends of mine. I did ask about 6 years ago if they had ever heard from her or found out what happened. I got a non-answer, indicating they did not want to discuss it. Very sad.
