What does everyone thing happened to MH that night?
I asked the same question about Hannah. LE has kept a lot of MH's particulars under wraps, and it's been a while, so it's a bit more difficult to come up with a theory.
My guess is that MH was looking for a ride "home". Apparently, she so told her friends that via text or phone call. Like Hannah who was in touch with friends for a while as she walked to that mall, so was MH when she got "locked out" of the concert arena. From what I have read, her friends lawyered up, so how much info they shared of the text messages and conversations remain unknown, maybe even to LE. But she was seen hitch hiking even, and witnesses have out and out said she was on something, drink or drugs.
So a cab rolls up and asks if she needs a ride. JM, perhaps, at her service. A calm honeyed voice saying he'd take her where ever. They can settle the tab later or maybe there is no tab, he says he's heading that way anyways. JM has been known to offer "freebie" taxi rides.
She'd likely go in the back She had hit her head, was taking some "stuff", was tired, upset, under the influence. Maybe she dozed off as the ride headed on, maybe she engaged in small talk with JM. I'm not sure how the cell phone, her purse and other things found in the arena area related here, as it would have been most risky to attack MH right there, take her phone, remove the battery, and pitch it with her purse. She may have just dropped those items herself unbeknownst to her. Some phones,, you drop, the battery goes one way the rest of the phone the other-I have such a cell phone.
When, where , how, MH would realize that they are not heading to where she wanted to go I don't think anyone would know for sure. Maybe now that LE has the cab they can see if she was in the back seat or front from DNA and if there are any signs of fight in the cab. I don't think so. I think he pulled off the road, maybe saying something about a problem with the car. Got out, maybe she jumped out to see too, or he just opened the car door and pulled her out before she realized there was a problem Or maybe she got out and ran and he caught her. Wouldn't have taken much to punch her and get her subdued and walk her to wherever to rape her, and kiill her Given what happened to the Fairfax victim, he could have strangled her while raping her Without interruption, finishing her off was not so difficult. No mention of marks on JM's face during that time. No one saying he showed up one day looking like he'd been in a cat fight. So there likely wasn't a whole lot done to him. He's just too big and strong for drugged up young women to give much resistance.
My guess is that he took the shirt and pitched it somewhere and someone else found it and displayed it. Doesn't sound like the sort of thing he'd take the time and care to do. I also think that his DNA is on that shirt, maybe on some thing with MH, or MH as well, with some reconstitution. Would be difficult, IMO without some significant DNA from JM on her person to get him for a murder charge here. Unless LE has some really good stuff. Reconstructing that evening in terms of JM's movements will likely be difficult If MH's DNA could be found in that cab, it would be great. Also JM's on her shirt (where I am betting it is) would also make for a strong progressions in that case. She was in Charlottesville for a very short time, and for her to have been in his cab, and have his DNA on her shirt is strong circumstantial evidence, unlke for Hannah whom we would expect to have some DNA in JM's car and possibly certain dna of JM on her pants. We all know they were together and that Hannah was willingly with her. MH spent most of her time in the area getting killed and being dead, so that a DNA link to JM is going to have a lot more impact, IMO.
