Don't forget Shayne's attempt to get immunity deal. To get immunity deal you have to have been involved or you would have nothing to deal with. IMO You would also not kill yourself after immunity deal fell apart unless you really, really didn't want to sit in prison waiting for death sentence to be carried out.
Respectfully, not true. SA's immunity deal was an attempt to get immunity for unrelated drug charges, and in it he never admitted any involvement in kidnapping, rape, or murder of HB whatsoever - and in fact his ability to get any immunity was totally tied to a complete NON involvement except after she was already dead (ie, probably disposal of her body). He never ever said he had anything to do with these charged crimes, and the state never charged him in any way.
