Hi Anita!
No doubt in my mind about the jury at this point is "waffling" just like you and me.
When it comes right down to it - they don't have much. Over a period of 4 days they've only requested the 911 recording and power points of the two experts. I doubt they will unanimously agree on the 911 call - it's a matter of interpretation and I can see it going both ways. after listening to it myself. Then I thought, even if you did push your child over a cliff, I'm sure you'd try and show some urgency in your 911 call.
As far as the 2 experts. They appear to be both well qualified. The defense expert says you can't make a determination if Lauren was thrown or fell because you don't know exactly where she left the cliff. Hayes says you can and he formed his opinion based on the Laws of Physics and police reports. So did Hayes even have the right location? CB told the police he was sitting on a rock 4 ft away from Lauren when she went over. Yet, when the jury gets up to the Pt to see where exactly Lauren went over there's no rock 4 ft away! Where did Hayes throw his 45 lb weight over? Does this cancel out Hayes' theory or does it even matter?
And, what about this rock? Was CB lying about where he was sitting or did she go over at a different point. He could very well have been sitting further away than he said so as to not sound totally negligent.
Maybe I'm over analyzing. I can certainly see where this jury might be struggling. I also think the prosecution made a mistake by not addressing the juror's question about this rock somehow. Sounds like it might be some sloppy police work which could create reasonable doubt.
