OK, so there was a guy who saw somebody pull up to her earlier in the day a couple hours before this happened while she was changing something outside. He later parked and went in to buy something, and this guy was driving a van that looked like the one on camera. How about this scenario:
He talked to her, he then went in and bought something with cash to find out more about her. He then left. He has been planning on doing something like this for a long time but has never actually done it. A couple hours later after thinking about it, he comes back at closing time. She has the drawer out because she is about to close. She recognizes the "friendly" guy and opens the door and asks what the problem is. He says to her he dropped his wallet somewhere, did she find it? She responds, no I didn't see anything. He continues "Hm, i swear I must of dropped it somewhere in here, do you guys have any cameras?" She, thinking this all being very innocent says "no they dont have any cameras here." He then proceeds to grab her, he drags her out, there is a struggle and gets her into the van. Just another possible scenario i suppose.
