I don't think so, because the whole point of the timeline was to discuss the various times that others saw Lisa. Why mention that she saw her alive and well at 4:30, but then NEVER mention seeing her again. They described dinnertime by listing the family members, with NO MENTION of Lisa being there.
And then they mention the sighting of Lisa by the 4 yr old. Wouldn't they include Samantha in that sighting if she saw her too?
I feel that the timeline laid out the various witness testimonies, and the LAST time samantha said she saw the baby was at 4:30 in her crib.
And again, if the 4 yr old was over to play with the boys, why would the baby girl have to be alone in her room? That makes no sense to me at all.
I mean she is in her crib while the kids are playing, and in her crib while the family eats dinner, then she is put to bed, with NO MORE CONTACT AT ALL, at 6;40?
