This has been unsolved long enough that I'd like to try something different, and I hope that everyone here will pitch in and add to the list.
I believe there is a possibility that the person who did this also murdered Lyric Cook and Elizabeth Collins in Evansdale Iowa on July 13, 2012. If we could make a list of facts that are common in both sets of murders, that might help us understand the man behind this. I'll start the list:
- two girls aged 8 and 10, and two other girls aged 13 and 14, abducted five years apart
- both occurred on the 13th day of the month: Friday July 13, 2012 and Monday, Feb 13, 2017
- girls were at local parks, but in an area where they were separated from other visitors
- girl's bodies were found 50 feet from a slow river
- at least one of each set of girls was an avid online communicator
- at least one of each set lived part time with a grandparent
- body locations are fishing/hunting/outdoorsman spots
- body locations suggest that the suspect has a familiarity with the area surrounding the park
- two set of girls have similar body types
- State Rd 218 exists very close to both murders, perhaps less than a mile from 4 lane highways
- both tiny rural towns.
- Small, inexperienced (in major crimes) police force
- Crimes both occurred in daylight hours (afternoon)
- "Bridges" exist at both locations.
- Weichman Pig dealing operations exist in both areas.
- Adding dates of birthdays and years may add up to 32 depending on how you do it. The number has a lot of negativity to it from history.
- Transco Railway products/services exist at both locations or very close (Logansport).
- "Rails to Trails" is an active org in both locations.
- Trails are located at both Monon High Bridge in Delphi and Meyers Lake in Evansdale (Evansdale Nature Trail/Cedar Valley Nature Trail)
- Geocaches hidden at Monon High Bridge, Meyers Lake and Seven Bridges
- The dates are also mirror images ... 7.13.12 and 2.13.17
I believe both are fairly close to meat packing places
With the Iowa case, everyone assumed that it was someone local, but the fact that their bodies were found 20 miles away at Seven Bridges Park suggests that someone knows the bigger fishing and hunting geography.
