I wonder if it's possible that LE thinks SA is more covering for BD, and not the other way around. I keep thinking that something could have happened Monday morning after SA left the house and before BD went to work. If he got a frantic call from her just as he was arriving at work, I could see him telling her to catch her ride as usual, go to work, and he'd figure something out. It explains the weird unexplained departure from work and trip back to CC right about the time BD was leaving the house. If he just wanted to get to Hailey after BD left, he could have just sat around the corner and called in sick. If he wasn't in a panic, he would probably have thought to turn off the cell phone much earlier in the day. If it's confirmed that someone saw him the whole time he was at work and he didn't take anything and no one got in his car with him, he had no reason to go in that day unless he fully intended to stay. It may not be that BD harmed her that morning, it may be that BD found her in bed unresponsive after she was drugged or otherwise violated the previous night. I can't get past that strange and incriminating departure from work without thinking he just found something out and didn't have time to plan ahead - he had to act immediately (before DD showed up back at the house). It would also explain BD's inability to cut off from SA.
Maybe she doesn't know anything about what happened and is being advised not to publicly throw SA under the bus in hopes that he'll spill something out of compassion for her, but I just don't get that vibe. Ughh, still not enough FACTS to do anything but speculate...
I so want to see the phone records for 12/27 and 12/28!
