I have a question for those who think this was a targeted attack. And I'm sincere. I'd like to better understand the thoughts behind this theory.
If there was a plan to kill the girls at the trail that day, than why did he cross the bridge (or the creek, if you believe he lead them from the south end and across the creek)? Why not hang around the north end and block their way back without crossing the bridge? Crossing the bridge (or the creek) seems unnecessary considering where the bodies were found.
I guess that's why I've always seen this as a random attack. Like he didn't really know what he was doing as he was doing it. I'm not saying he hadn't already decided to kill them (or abduct, or SA), possibly, once he saw them (so targeted after the fact), but I don't see his actions as boldly per-meditated.
Also, to be fair, I'm not looking at this with a specific suspect in mind. I'm open to the idea that crossing the bridge/creek was reasonable in the right circumstances, to the right person.
Please give me your thoughts.
