@hawkeye10,
That's one possibility--that she dug up the dirt on her.
The other is just that she played on Scheibe's sympathy, and I do believe Scheibe wants Zimmerman to get psychiatric help. Zimmerman's lawyer may have gotten him to agree to go for help--I'm sure she agrees he needs it. And all along what motivated Scheibe to get involved with him, and to stay with him, and to keep forgiving him, for all the crap she was putting up with, was that she felt sorry for him. This was no great romance.
So the lawyer may have played on Scheibe's desire to help him, convinced her he would see a shrink, and leave town, but that if she went through with this case, she'd destroy him and finish him off.
But Scheibe, like Shellie, may have gotten herself into legal difficulty for him, if she's now, in effect, saying her police report was false. Her cover is saying the police intimated her, but that won't work. Her other choice is to tell the truth. I don't think her police statement was false. But, she can just say she wants the charges dropped because she overreacted to what he did. I'm sure Zimmerman's lawyer can handle it for her.
