This case haunts and bothers me. I have watched at least 4 documentaries about this case and each one provides just a bit more information.
IMHO, the way the boys' bodies were found, including "hog tying" with their own shoe laces, tells me whoever did this took their time. Not only did they take their time, but the boys must not have screamed for help as they would have been heard by people in the neighborhood. And/or they knew their attacker as a supervisory figure.
Based on the interviews I have seen with Echols, Misskelley Jr and Baldwin, these "kids" were not skilled enough to pull off this crime.
Additionally, I believe the timeline of reported events rules out some crazy from the truck stop.
There is no evidence to support it, but I believe Terry Hobbs had something to do with this.
