things i had talked to the detectives early on, do you think an accident could have occurred? they checked out that whole area. i was worried last year when caylee wasn't really sure-footed and the steps going up there. we always carried her. i was worried about slipping. it is a steep ladder. we always made sure there was always two adults. you would hand one off. this year caylee was great climbing the steps. we had a routine where she climbed a certain level and we were sure-footed on the ground so there was no slippage coming down those steps. i still was concerned, what if? the one thing i'm absolutely positively sure of if there was an accident why would casey want to hide something? she would be calling 911 frantically saying something has happened to my daughter, can you come help? there's a lot of drowning victims that come back. i had a close friend years ago,
