I originally thought killing her took more than one day, if that's what happened, because of his movements and actions from the 27th to the 29th. Especially since he was spotted driving so slowly and "acting weird" by eye witnesses.
I saw the crime scene photos last night of the log marked "16" by LE and that definitely looks like drops of blood on that log. One below the 16, and two above it. So now I"m not so sure it took a long time to kill her, whoever did it. There are a lot of marks on pieces of wood and rock so potentially, maybe a lot of blood and evidence. The autopsy results will probably tell us a lot about what happened.
I'm also at the point where I think BL probably offed himself. He probably has no future outside of jail, where ever he may be hiding, and that might have sunk in for him. It would not be such a tragedy if he did, IMO. Save the taxpayers a lot of money paying for a long trial and his life in jail. They can still find out a lot from the autopsy, from evidence at the scene, and more witness accounts will probably come out.
IMO
