Didn't Brad say he was vacuuming the car because of gas he spilled a week or two earlier?? That's the unusual part to me, not the use of the ShopVac.
ncsu95 - I don't understand your thinking. On the one hand, you say BC is the "likely" murderer. On the other, you say he should have his kids until charged with the crime. I'm pretty sure that the judge's comment means that if she determines, as you did, that BC is the "likely" murderer, then he will not get his kids.
Also, don't forget that BC agreed to the current arrangement. He didn't force a hearing, he just allowed the gp's to take the kids. I don't believe that I would have let my kids go for a second without a fight.
He chose to attempt to answer "internet speculation" in his affidavits for this custody case. Much of what is contained has very little to no bearing on the custody case. By doing that, he created even more speculation, because he has several inconsistencies in his story (First he had to go get milk at 6am to get ready for Katie to get up, then Katie's up at 4am and won't go back to sleep so he goes to get milk, among others)
I don't believe for one second that the subpoenas for evidence are really related to the custody case. I think his criminal attorneys just want to know what they are up against.
