Expounding on something I wrote on the box wine thread...
FWIW, here's what I think. I think DB was sitting around outside with her neighbors having wine, smoking, and shooting the breeze that Tuesday evening. The kids were playing together and it was probably a typical routine for them. They ran out of wine so Deborah asks her brother to run her to the store for more wine and diapers. The reason I think they were already drinking is because a) the wine isle is their first stop and b) DB looks at the coolers first to see if there's any cold wine in her flavor (IMO) because she wants to drink it right away. She sees there is none, so she grabs the box and they head for the diaper isle. She never asks the brother if he likes this or that wine because IMO, he's not drinking. I see only DB paying and grabbing the priority, the wine, and the clerk handing DB's brother the rest of the purchase. As they leave the store the keys are in the brother's hand. He looks totally disinterested in the events of the trip. DB looked happy and in a hurry to get back to wherever she was headed.
The fact that her brother was her ride to the store makes me think he could have been her ride to go somewhere else that night - drug run maybe? I've known people whose routine was much like this on a daily basis, and some had babies in the house that they loved, but that didn't stop them from having a good time. The drugs run out and they go and get more - sometimes it takes hours to procure them. Moms give their babies a little something to make sure they stay asleep while they are gone.
The kitten in the bed with the little boy may have been a trade off to ensure he stayed in bed like a good boy while mommy is gone. "if you get out of bed I will take the kitten away!"
2:30 am - "Ready when you are..." If the unverified text allegation is true, this sounds way too casual to be a signal for burying a dead baby, even for a callous individual. Sounds more like ready to make a run. Again, no idea whether or not this text ever happened, but for this scenario as to why the brother was involved at all, it would make sense.
She gets back home to find she had given little Lisa too much nyquil or sleepy meds. She freaks out but has to stay quiet because the boys are sleeping. She's messed up and can't call the cops because they will see she's messed up - and they might find the drugs that were just purchased. She will look like a horrible mother and JI will kill her (figuratively), if he finds out she drugged little Lisa so she could make the drug run.
Panicked and seeing the time is around 3:30, she doesn't know what else to do but give the baby to her brother and claim she was kidnapped - what about the phones? Take those too and get rid of the text messages. It's getting close to time for JI to get home. Wanting to make the kidnapping scenario look authentic, she opens the window in the computer room and tries to pull the screen off from the inside because she can't reach it from the outside - she's struggling with it when JI's car pulls up. She abandons the effort and runs to bed, if she turned the lights off now he'd know she was awake.
All the emotion she showed to JI, the cops, and the media the next day would be genuine. She didn't kill Lisa on purpose, but she was so drugged up she overdosed Lisa - if anyone found out, she would lose her little boy as well.
Lisa knows what happened and JI probably suspects something is not right.
Of course my theory doesn't hold water as far as the brother if he had an alibi that night. Does anyone know?
If there was an early morning run to the dealers house, the dealer wouldn't come forward, for obvious reasons - BUT - he may turn his entire life around for $100,000!
