Yes, this is established as fact.
There was blood on the socks, not sure if they were "saturated", can you provide link?
NOT a fact. As noted upthread, the blood testimony described "stains" on the pajama bottoms. In addition, the only basis for the pajamas "appearing" clean was based on recollection and casual observation, not based on a close examination of the PJ's at the time.
This has NOT been established. Description in a search warrant does not establish it as fact. Again, this can be easily answered with the photograph of the carpet in the hall leading up to the bathroom.
See previous comment.
Yes, this is also established as fact.
Definitely chain of custody issues raised here, and this is a mixture of fact and opinion (e.g. for unknown reasons).
"not a trace of blood on her" is not a fact. 911 calls capture some of what CY was saying, which is consistent with her being there alone. The factual evidence can lead to several conclusions, but first it is important to establish what is fact and what is not. The above is mostly not established fact, and some of it is refuted by the evidence.
