Way back in the threads I remember There was a link to MSM that stated on the 13th the areas around the bridge and downstream from the bridge were searched in case one or both girls had fallen. The girls were found upstream from the bridge, so we don't know how long or how extensively areas upstream or on or around RL's property were searched on the 13th. It was also stated in MSM that the family/friend speculation was the girls could have gone to another friend's house, were with other friends, went to a brother's house, tried hitchhiking to Libby's mom's house, etc, etc, etc. No one suspected foul play. They probably all thought the girls would turn up alive, probably cold and hungry, but certainly not harmed by anyone. Small town life is different. I went through culture shock when I found out people didn't lock their doors when they went to bed. Or when they run into the grocery store and leave the engine running and the car unlocked (because the keys are in the ignition) so the heater or a/c can stay on and the car won't be too cold or hot when they come out. And the vehicle is always there when they're done shopping. No grand theft auto! I remember being a teenager and pressing the power locks to lock the car and my mom yelling not to because she was leaving the motor running and my dad had the other set of keys. Not locking your car? Leaving it running? I was in shock. Speechless. It's just totally different in a small town. Totally. If anyone's interested, go watch a rerun of the Andy Griffith show. Tiny towns are like Mayberry, except now they have the Internet and satellite TV. HTH.
