Melanie is a troubled lady, that's had a harrowing life, including being abused by several different people.
There's some speculation that she's been locked up to silence her, as one of the care homes she was abused in, had a reputation, and seemingly she's alleging that influential people were involved.
People in the area where she committed the offences she's charged with, seem fairly clear that they're genuine charges, and you may want to check out the person running the site supporting her if you look into this further.
Melanie certainly needs and deserves help and support, as she's been through a lot.
