If there had been blood on the ground, I believe the dogs could have still picked up on it. We had rain that night, but not as heavy as it has been before and since then. It was still a good rain though, so it is iffy. The cadaver dogs would have found a body on the ground by now if it were there to find. I don't believe she was ever on the ground.
The cops even say they don't have a solid timeline and that is what makes this so incredibly frustrating and to me, casts a lot of suspicion on the mother. I think she went to the jail with Leoana's father to try to find out what Travis may have told the cops. There's no doubt in my mind that this mother knows more than she is saying, whether she was directly involved or witnessed it or whatever. A mother never talks about her child in past tense unless they've had the heartbreak of burying them imho.
