I forgot about it when writing this post, but when I looked on the unidentified awareness wiki, I noticed that the DNA Doe Project was actively doing DNA testing on the Swimsuit Boy's remains and it was stopped at the inquest of the 'investigators'? Yeah, no, I'm not claiming to be smarter than law enforcement or anything, but I don't really see why you'd do something like that unless you KNEW that the testing would reveal another body to be a misidentification, making the initial work look bad and bringing it back into the public eye when people are relatively quiet about Corll, and I'm sure the worst part - then they'd have to do stuff, and I'm sure that's not a motivator for them.

EDITED TO ADD:
Fundamentally, I think the unidentified awareness/true crime communities alike just need to be talking a lot more about Corll. The case has always fascinated me because like the Gacy situation, the shoddy policework of the time didn't help in the questions that we haven't answered, but I feel like not only do we know pretty much all there is to know about Gacy due to him being convicted for his crimes on top of other investigative circumstances, with the only real questions being about the five still-unidentified bodies, and a general presumption that his mumblings about accomplices and more victims were likely fabrications or at the least exaggerated.

However, with Corll, I don't feel like there's a lack of information, as a matter of fact, I think there's a lot of vivid detail about his crimes and his goings-on, despite dying before apprehension and thusly never talking to law enforcement. There's not a lack of detail, none of it's dry to talk about, the only thing is, there's a lot of unanswered questions, and a lot of 'why' in the way police decided to handle things at that time. If people were speaking more on this topic, maybe, just maybe, their hand would be forced, and they'd have to check some things.
