I’m a bit behind so apologies if someone has mentioned this or my info is outdated. I’m getting flashbacks to the murders of Kathryn & Alvin Liknes & their grandson Nathan O’Brien. Nathan had spent the night with his grandparents and when his mother couldn’t get ahold of them the next morning, went to the house, found they were missing and blood in the house. The police immediately told the public the disappearance was suspicious but didn’t mention anything about blood until 5 days later. (trigger warning that the details in this case are horrific, just in case you aren’t familiar with it and do further reading).
I’m guessing it’s not likely there was visible blood when the family discovered her missing since they searched for her themselves for awhile initially, but maybe police were able to find it if it wasn’t visible to the naked eye.
