@Alexander Hamilton I've got a couple questions/thoughts, maybe they've been answered already.
1. Is a confession from Chris to an unrelated third party who was using a pseudonym really enough (assuming there's no concrete DNA evidence or evidence of sexually indiced injuries)? He also "confessed" to being a pedophile because he was being trolled. He's also so far gone at this point that he can't distinguish fantasy from reality.
2. If Barb is as senile as people seem to think, can she even be considered a reliable witness?
3. Allegedly, the audio shared by "Bella" has a voice changer on it, meaning that in some form it has been tampered with. Is there a risk that can get thrown out for being unreliable/inadmissible due to tampering?
4. Back to the confession to "Bella", are text messages shared through the internet even admissible? Or would they need to get logs from the service used for the messaging? Like a phone service carrier or Facebook or Whatsapp.
5. Can the defense reasonably make a case from the years of inappropriate behaviour between Chris and Barb like the post-fire spooning, assuming this is rape by the victim saying yes but being unable to legally consent? (i.e. Barb is too mentally feeble to be able to consent to sex with someone like Chris)
6. I know you've already touched on that Chris acknowledged he took money from Barb's account that might not have been his, but Barb has a habit of spending Chris' money. Could that invalidate any claims that Chris violated the EPO?
