That was in the paragraph right above the one I'm referencing.
What I'm referring to is the second to last sentence on page 2. Several words are blacked out in that sentence, and it was right before he asked to speak to his dad and then he would tell the truth.
We've discussed this blacked sentence before, but I don't think we ever really figured out what it was. If the Denver7 article is accurate and it says police documents said he admitting to doing so (killing them) then I think it's possible he admitted it during his interrogation and then came back with his confession, which was the lie about Shanann.
It that is accurate, he was totally toasted, because that would have been used against him. IMO.
