According to Kiwifarms, back then Chris would have been released months ago if weren't because of his retarded letters where he openly admited having raped his mother, which caused a ton of people to report him to the law and made things a ton more complicated because basically every time Chris opened his mouth he admited having done things he adamantly refused to admit to his lawyer and jury.
Case in point: here's one of the tard's drawings where his fursona is making out with his mother's comic self. Kind of difficult to prove his innocence after this evidence of his inner thoughts and true intentions is released to the public.
