I'm with you, Leila. I think he still wants to believe he heard Caylee during the phone call on 6/24 but he's honest enough to say he can't be 100% sure like testify to it in court. It's also probably hard for him to imagine Casey being capable of killing Caylee. MOOI'm impressed with Jesse. I think he was very sincere, and honest. I can't fault him for having hope that Caylee is still alive. I think he loved Caylee........you can see it in the pictures of him holding her as a baby.
I think Jesse is simply having difficulty grasping what's happened. This is a trying time for him.
