Brendans comments regarding the stabbing in the jeep could have been born from the media coverage following its discovery. Im sure his classmates, family, even strangers were coming up with opinions and gossip.They do suggest the yelling and screaming, on page 508 of the second transcript, they ask "Did he say if she was yelling or screaming or anything" and he responds No. They also suggest a struggle, and he also says No. They also suggest Steven had been injured when they ask him "Did he tell you at any time that he had been injured when he killed Teresa" and he first says no, then says a scratch, and w. further prompting, says a scratch on his finger (already common knowledge by this point I assume)
He responds no to "did you directly stab her" and "did you put her in the fire" so he also has not given them enough to arrest him at this point, or implicated himself.
One piece of information that I believe was true, or he at least believed to be the truth, or Steven told him to be the truth was when he states Teresa was stabbed in the jeep. He is asked- where did he stab her? in the garage? in the house? but he answers none of the answers suggested and says "the jeep" which he brought up on his own.
Lastly, he states Steven called him on the house phone. This is easily corroborated, does anyone know if they corroborated it, or at least tried to corroborate it? As I've said earlier, a confession is useless unless corroborated.
