Indeed. Additionally, some other victims could be related to our girls here, moo.
Yeah. I really don't think this was BG's first rodeo.
Here's what I'm going to be researching: possible related cases. I'm looking at a map of the midwest with Delphi on one end and Waterloo Iowa where L&L were, and thinking about the serial killer pattern stuff I've read over the years about patterns and mind maps. The idea is that a killer has a certain comfort zone within which he commits his crimes. I first heard about it with the Grim Sleeper in Los Angeles, whose crimes lined up along I-5 through downtown. Everything was within about a mile on either side.
Another common pattern is a shape like a plus sign, where the killer has a line between home and work site (or another significant location, like a girlfriend's house) and the crimes will be on a line perpendicular to that line. For that pattern, often the hunting site will be at one end and the dump site will be at the other.
And there's the circle, where the crimes are spread out at about equal distance from the killer's home territory. That's very common.
Things like truck driver killers and the killer who has a connection to a relatively distant piece of land (like a grandparents' house or the place they grew up) are harder to pin down.
Distances are usually about half an hour to an hour's drive, though some are longer, especially in bigger states.
Assuming for the moment that the Delphi killer has killed before, and that the Iowa girls are also his victims--I'm not sure what I see. (Not enough data.) There are several fairly direct routes, the most direct being via I-74 and I-80 to I-380; it's somewhat longer than the usual pattern but it's a somewhat sparsely populated area so might require being spread out more.
That gives a midpoint somewhere in the Peoria-Bloomington area. Bloomington is right at the intersection of several major interstate highways. If you look north and south about the same distance, which could fit either a plus-sign or a circular pattern, there would be potential crime areas (probably dump sites) in southern Wisconsin and the St. Louis area to the south (though I'm thinking more likely the farm country between St. Louis and Louisville).
I can already think of one possibility: the girl known as Fond du Lac Jane Doe was found in a stream in a rural area in 2008.
