This is just speculation, and I'm not able to research this at the moment, but several weeks ago a young Amish girl was stopped along the road by a man who tried to get her into his pick-up truck. I don't know if they caught him. I can't remember ever hearing of something like that happening before. When this news came out yesterday I immediately wondered if this man was the same one. Or if the girl was a student in that school.
Wow. I am sure the PSP is all over every incident involving the Amish; their children, etc. I wonder if the killer drives a pick up? Maybe it wasn't him, but maybe he was questioned, fit a general description, etc., and that was the 'something' that set off his rage against little girls and/or the Amish.
