A map is going to be interesting. I'm not real familar with the area so I can't read all of them. But what I do see is that he seems like an hunter. Yet he wasn't above hunting in his own home grounds, as he took two from near his home. He is also confident, taking two at one time. He hunted as much as 4-5 hours away, but his dump sites will be relatively close (1/2- 1 hour or so) to the abduction site. Were the disposal sites near the bondage sites?
That seems to be his only clear pattern, without knowing exactly where he picked up most of his victims up at, which he had already figured , that is what allowed him to be such an effective hunter, he disposed of the bodies close to his kill site.
Your sister would have been an anomaly for him. First he had an aquaintanship with her.
Several of his victims were known to him,...actually he did not start abducting victims not known to him until his confidence was higher. Bonadies was his neighbor, and Hallock he dated, Hutchions was a cocktail waitress, they may have dated also, even Susan Place and Georgia Jessup, willingly left their house with him, he used a fake name, Jerry Sheppard, but he appears to have been fond of selecting his victims from those known to him
Not with the others. Second she was a single, and he seemed to like to abduct doubles.
I actually think she may have been his last single, for after her they all seem to be doubles.
So yes, there might have been changes in some of the MO on her. Third she was younger then his usual age range that I am seeing so far.
Mary Briscolina and Elsie Farmer were 14 years old, and my sister was not your typical 13 year old, her measurements were 36-26-34, so most people thought her older than 13, and she was not his youngest...
Still it has happened before that an SK will have one younger than the usual.
A better case exists for Schaefers involvement in the murders of 9-year-old Peggy Rahn and 8-year-old Wendy Stevenson, in Pompano Beach. Both vanished from the beach on December 29, 1970.
Peggy & Wendy just happened along at a time when I was curious about [1930s cannibal Albert] Fishs craving for the flesh of young girls....I assure you these girls were not molested sexually. I found both of them very satisfactory, particularly with sautéed onions and peppers.
As a hunter he would be looking for several things. Opportunity....the girls/women would need to be in a situation that he could get to them without a lot of close witnesses
He did not have to worry a lot about witnesses, that was where his police vehicle came in, who really stops and thinks anything might be wrong when you see someone pulled over, or when you see a patrol car pulled up to somebody?
They would need to appeal to him. He would need to have the time for the hunt, activity and disposal.
That seems to be his one clear pattern, he disposed of all the bodies close to where he hung and tortured them
(LE schedules would be ideal for that, in that he would have odd days and hours off. eg he might get off work at 6:30 am on wed and not be due to report back to work till midnight on fri.)
