I agree with you. I don't know if she knew her abductor but I feel that whoever it was knew her schedule. It could be a simple as him driving by at the same time every day to or from work and seeing her at the same time. Or it could be that it is someone in any of the school or organizations she belongs to. Someone noticed her and then probably made it a practice of learning her schedule.
I'll share a little story. When I was a teenager my sister and I would babysit for the neighbor right across the street from us. She was a nurse 3-11. And she only worked 3 days a week. At some point some SO saw that we were coming and going. We lived in the country. This man would ring the doorbell and he would be completely naked. I'll leave out the details. We would call the police but of course it would take them 10 minutes to respond and he would be gone. This happened over 20 times before they caught this man. And he never appeared except when we were babysitting. He was watching us. This happened in the dead of winter in New England. Naked in the snow he was at times.
We were so traumatized we stopped babysitting. This was back in the 60's when the good ole boy club was still in full force and no Sex Offender laws in place like today. They caught him..... but he got a slap on the wrist. One night as we were leaving he reached out to grab my sister by the arm and we fought him off. We didn't know him at all. But he knew us and our schedule. All it takes is a pervert to see you once and set their sites on finding out what they need to about you and your schedule. It could be anyone that took Holly.
The time frame of her abduction IMO is a really good place to start looking.
Wow- what a creepy story, but I have a feeling things like this happen more often than we realize.
I agree, I don't think it was necessarily someone who KNEW Holly, per se. Obviously, he planned this out and had an idea that she would be coming out that morning, but I don't think he did a whole lot of "homework," because Clint was home, and he either didn't know or didn't care.
