As I've stated more times than I can count on this thread going back several years, if illegals were in the business of kidnapping and trafficking American educated women, there would be fine up-standing American women disappearing every day, just like Jennifer Kesse did.
But that's not the case. Human trafficking certainly involves mostly women, but not American women. Not educated American women. Not independent educated American women, like Jennifer Kesse is/was. Why? Frankly, because American women ARE educated AND independent AND tend to be pretty good fighters. In other words, they're just not worth the hassle, no matter how attractive/smart/personable they are.
For example, when I lived in Las Vegas, a major human trafficking ring was broken up. And the victims were all women. And not one of them was an American and not one of them spoke English. As I remember it, they were all from SE Asia. Now if there is a human trafficking ring that was broken up in, say, Vietnam where the victims were all American female real estate agents, then I stand corrected. But I'm guessing that's never happened nor ever will happen.
So, the Kesse's belief that Jennifer was trafficked just isn't plausible or probable. Possible? I guess, at like 1 in a million odds.
There's also something about the belief that the apartment complex workers were the perpetrators that strikes me as racist. Fact: American citizens still commit a vast majority of the crimes in the USA. As for one of the former workers being charged with rape later, you randomly pick 100 American men and you'd find probably a couple who have rape or some other violent crime on their rap sheet.
A man who knew Jennifer well--you can take that to mean whatever you want--is responsible for her disappearance. She had men outside of her bf who liked her, wanted her, were jealous of her, etc. And that's always a recipe for a guy losing control even if he regrets doing it later.
