Those are VERY small towns. In a town that size, everyone knows everyone else. 7 miles away the same (Mount Holly).
I find many things strange in this case. The fact that the abductor DIDN'T just drive up to the house and pick her up.
He could very well have picked her up and never went back. But he chose the A&P location. I find it odd that he chose the babysitting gig for the morning. Possibly when Margaret's father was working and the mother was busy.
Did he know the house's schedule of comings and goings? The father spoke to the abductor on the phone it says to get a feel of what she was getting into.
He felt it wasn't a threat. But now I wonder if the abductor disguised his voice and knew the father's psychological red flags.
This abductor was hell-bent on it being in another town and during work hours. That should've been the FIRST red-flag that he wasn't working that day.
It says in that video that Margaret Ellen Fox has recently taken up piano lessons and was learning how to ride horses.
Was this an piano or horse-riding instructor that had developed another type of unhealthy attachment to her? Both instructions require sometimes the instructor to use their hands to assist you. In piano is to show you proper have technique and positioning. The horse-riding to help her 5'2" frame up into the saddle. Both require hours together.
Were those instructors male or female? A horse-riding instructor WOULDN'T be in town. He'd be in the country areas.
Have they researched that part of the possibility. She may have ran out of money to take both piano and horse-riding and might even told her instructors in piano and horse-riding her plans to go earn money by babysitting and she'd be back. She could've told them she placed the ad in the paper also. But they might've not known that her cousin did also. They called the cousin in error and make an excuse that she's too young then raise the other is Margaret's ad in the paper.
We also have to think that this meeting happened in public. She DIDN'T make a scene or scream from what we know in the supermarket area. I wonder if the last male she was seen talking to in that parking lot of the A&P with the red sportscar was associated with the piano and horse-riding instructor in any way.
I'm thinking it's a firm possibility that the abductor lures her there, makes it look like he didn't show. When the actual person she was talking to was someone she ALREADY knew. Then they offer her a ride home, never to be seen again. For her to NOT make a scene, nor yell makes me think what normally we read in these cases, he offers her a ride.
It would fit.
He didn't show, then acts like he comes out of the store getting some bread,.
Offers her a ride back home and she never returns.
I wonder who the piano and horse-riding instructors were. Horse-riding means he has pasture land. A lot of land. Remote.
