I have continued keeping up with Jane's case since I published my article in 2016, so to answer questions I didn't previously, in no specific order:
It was Brookhaven Trailer Park.
While they basically found skeletal remains, there were also tatters of a shirt (much like the pink shirt the girl was wearing in the photos) and some hair. The hair is African-American.
She wasn't at a daycare, she was at a Vacation Bible School, and having spoken to a few people in my area who run similar programs, records are rarely kept at all, and certainly wouldn't have been kept five years (the photos are from 2011, but it wasn't until 2016 that someone really noticed them when they were going through old photos they had taken - this was the same person who remembered her as keeping to herself, not well socialized, and unkempt). When she realized they might be photos of Jane, she brought them to the OPD.
OPD did look into everyone who lived in that trailer park and did not find anyone of note for this case.
Ground level view shows the road goes right over the creekbed where she was found. If she was dumped in September (decaying smell was noticed in the area in fall 2011, and you've ever lived near a creek or river, that's not an unusual smell) the trees would have provided a lot of cover for someone to easily dump her body over the railing from the road above. If they figured she'd land in the creek and float away it would be someone who did NOT live by that creek, as they would have known better.
I still lean toward Selah. One of the things I discovered while digging around about her case struck me funny, and I did mention it to the detective when I spoke to him - Selah, her mother, and her mother's boyfriend were all listed as having gone missing together in upstate NY. However, I found him alive and well in NJ. He has since been removed from Selah's missing page. I don't know what's going on with that now. As Selah's mother went missing with her, I'm not sure if there's any family still alive to run DNA against.
I don't rule out that the mother could be an illegal immigrant or victim of traffickers. If that is Jane in the photos, while yes, her hair is done, it was noted that it was not done very well (same lady that turned in the photos to police noted that). It still would have taken time to do (hour, hour and half if you have plenty of practice, maybe more than two hours if you don't), that sounds like it was not professionally done.
I still lean heavily towards trauma as the cause of the eyeflash, since there was healed or healing damage to the skull in that area.
There were, as I noted in previous posts, several girls I was able to rule out entirely, or rule as likely alive parental abductions. Many have also since been removed from the missing list that existed at the time I started researching. This was information I shared with with OPD but did not publish.
I am presently working on creating a Youtube video about her. If anyone can think of something I should add, I'd appreciate the input.
ETA: Rosemere Cemetery was ruled out as a source of her remains.
Opelika has a high crime rate. VERY high.
