Someone placed the tape there but there was no proof Casey did it. There is no proof Casey killed the child. There was no cause of death established and there was no proof she dumped the body.
Hope you never serve on a jury.
“The child drowned in the pool and Casey and her father disposed of the body to make it look like a murder”
The only reason that the rest of the evidence is missing is because it was destroyed by the elements since Casey failed to report the death of the child. She lied to police and her family which gained her precious time for the evidence to be destroyed. In the end she is free because of her lies. The alternate juror who has stated that none of the evidence against Casey was compelling and that he believed the father had something to do with it. If the rest of the jury has this same thought then I would say our legal system is completely broken. In the future all a murderer will have to do is destroy the body and say the person drowned. A defendant can tell complete lies from start to finish and that can be ignored.
