It's been done to death on COTH.

This is what she was charged under...I highlighted in red what might be the catch all she got charged under....who knows the truth.....certainly not I.

Looking at the photo of the poor horse makes my stomach turn, that poor poor animal!

Has she spoken up about the horses?

The story was picked up by Yahoo news, which is a really credible news source.
.I tend to think where there's smoke there's fire when it comes to abuse of horses, dogs, people, etc. Maybe that's just my experience, but regardless of the rescue operation, that horse looked terrible.
I wonder why she hasn't spoken up through her lawyer.
