The American justice system moves extremely slowly, especially when you’re relying on an overworked public defender. Those cases take at least six months, and that’s without the complications Chris brings to the table.
Most likely, Chris is in a mental health facility. They don’t want to release him if they think he’s a threat to himself or others. Between talking about being god, dimensional merges and an extreme concern for his toys, the court knows he’s not mentally sound. Given his lack of remorse, his prior history of offenses and the fact that 14 Branchland Ct is where he’s going to live (and the courts don’t want him living with his victim),
If Chris wants to get out, his chances go way up if Barb dies or goes into a nursing home. Even then, he’s going to be under heavy supervision. Barb never told Chris no; his tard wrangler won’t be so permissive.
