With all the HT talk here I just wanted to say that the article I referenced earlier today has some very specific information which could point that way IF you read through to the comments.
As a little bit of some background to just how bad HT is in Michigan: I am from a smaller town in Northern Michigan, anyone who knows the area knows what the demographics are like up there. Less than a year ago a man showed up at the school of my friend's daughter. She was in 10th grade at the time, she is beautiful, sweet, goofy, and goes out of her way to talk to, and help pretty much anyone. She is a "good girl" (not that it matters when someone is a victim) but she has colorful hair and wears a fake nose ring and quite often has henna tattoos, etc, meaning some people assume she is NOT a "good girl". Her father is a blatant racist and in her attempt to be as opposite as him she made an acquaintance at the mall who was a different race...who also happened to be well into his 20s but told her he was 18. He claimed he was up from "downstate" and was looking for apartments by the college and asked for her help. She sat in the food court with him for a bit, gave him her cell phone number in case he needed help finding a place. He reached out to her numerous times and was basically wooing her. She wasn't interested but being the sweet, naive girl that she is, she didn't know how to shut it down.
Well, that man is who showed up at her locked-down-tight private school with a dozen pizzas for "Katie" and her friends. The school was smart and called the parents and the police immediately while pulling "Katie" into the teacher's lounge without letting her know what was going on. The guy got spooked and takes off. Everyone is scared at that point, she has to fess up to giving a stranger her cell phone number, her racist dad has more ammunition to fuel his stupidity and they're all on pins and needles until two weeks later when the cops call. The dude was picked up trying to cross the Canadian border with underage girls, he was a trafficker and had been on their radar as potentially such. "Katie" looked like a girl who might fit some of the parameters a trafficker would look for in a potential victim, but despite what she looks like she actually comes from a warm, double-income, college educated home who's parents would have sounded the alarm if she was 10 minutes late from anything.
HT is a huge problem in the state and the bad guys do not always follow the "rules" of who gets trafficked.
Not saying it's what happened to Dani, a year ago I never would have contemplated it but IMO it shouldn't be discounted completely.
