There seems to be two different accounts of what Cindy actually said about the ladder.
From Steph Watts blog, May 24th, 2011:
Steph Watts - But heres what strange. I remember being in the house shortly after this story broke, myself and Mark Fuhrman. George and Cindy were taking us on a detailed tour of the house including the backyard where they let very few, other reporters in. They showed us the towering bamboo, the shed that investigators had moved, the gates and 3 other sheds that George says were always locked and most importantly the pool. It was an above ground pool, and Cindy commented, in detail that she remembers that she had left the ladder down the dy after Fathers Day. She was very clear about this as she stated that she always left the ladder up, so Caylee couldnt get up it but she remembered that day that she forgot, and had left it down.

VAN SUSTEREN: All right. Now, the business about the -- there's a pool in the back yard, and there's something about the ladder connected to the pool. And in fact, if you can just stand over on -- I've actually got a picture, so you can explain the significance of new information on the ladder and the pool in the back yard. What is the story on this ladder?
MARK FUHRMAN, FMR LAPD HOMICIDE DETECTIVE: Well, it's interesting. You know, the grandparents are telling me that on the 16th, when Casey and Caylee are leaving that morning at 12:50 -- the previous night, Cynthia, the grandmother, and Casey swam in the pool. After they were done, they take me ladder, which snaps off, and then they take the ladder away from the pool so Caylee can't climb up it by herself. Now, nobody swam in the pool after that night on Sunday. Nobody swam there on Monday. And then Tuesday morning, they noticed that the ladder was back up on the pool, hooked up, and the gate on the side of the house was open. So it's interesting information considering the activity that preceded -- you know, preceded that on the day before.
