I guess I'd like to add that the speculation about George Martinez doesn't really help, in my opinion, though hey, I guess anything's worth a look. His name's on a set of scales in her room. That's it. They look well used. There's a photo of her with a Hispanic-looking guy from a photobooth. He may or may not be George Martinez. It's apparently not Eduardo Colin, though his family are forthcoming enough to say that the signature at the desk is legitimately his (though the plates are apparently fictitious). She appears to have committed suicide after consuming heroin and some alcohol. She has locked the door from the inside after making sure that any identification she may have had has been disposed of, presumably because she doesn't want to be identified. She has left behind $500, demonstrating that it wasn't abject poverty that drove her to kill herself, but also perhaps as a way, in her mind, of defraying the hassle of dealing with her death.
I know that Gladys Cromer is outside the estimated age range. I also know that the autopsy appears to have been thorough, so you might expect to have an note if it were clear she had given birth, but I've also seen where age ranges are wrong, and where significant details are left out of autopsy reports. In this case, the body is said to have been moderately decomposed (after 2 or 3 days by most accounts), and the eyes cloudy, though color was positively specified as hazel. Despite the moderate decomposition, the coroner notes that there are electrode pads on the body from (presumably) the EMTs giving jolting her a go.
Unfortunately, NamUs doesn't specify whether they have a DNA profile. We also have to assume that the other materials in the suitcase really didn't offer anything that might help to identify.
I like Gladys as a possibility also because she seems to have been wearing clothes stylistically similar to AJD was found with when she disappeared, and because, judging by the earrings and necklace from her photo she like chunky-style jewelry. I know it was all the rage, I know that the clothes are very mainstream, too. Her hair and facial features, nose, eyebrows, jawline, ears seem to line up. From what we can tell given the photobooth pic AJD seems to have had pretty regular dentition in front.
In a thread elsewhere that I saw, Gladys had visited an aunt a few weeks before going missing. She was brought in a black car with blacked out windows. She said that her boss was going to take her to Fairfield Glade, but the aunt couldn't see what her boss looked like at all. Fairfield Glade seems to be a resort/retirement community, and she was at the time dressed all in black, which seems like it would have been appropriate for working in a dining facility. I'm assuming that if this job were above board, LE would have found her payment records. Fairfield Glade to Crossville is about 10 miles/15 minutes by car.
I find it interesting that her aunt seems to think that these details may be significant. If she were going out to party with people whom she'd met at this new job, it might explain why her sister didn't ask her for more specifics, since they probably wouldn't be people whom she knew. The clothing is pretty specific, and pretty casual.
She seems then have left her 1-year-old daughter in her sister's care to party with individuals unknown, and that was the last known sighting. For reasons that are unclear to me, these individuals are said by some to have been two in number, but considering that her sister seems not to have had any names, it's hard to know where that information has come from.
