I read through the S/W for the bank records, and noted that it was the bank teller who called the Det/Srg. with info that JP had gone to the bank and had withdrawn 7K on Saturday.
I think that a lot of folks who didn't know who JP was before he did this, recognized him afterwards, and made some calls to their PD, and the PD is working all their leads as hard as they can.
As for the sister, I do hope we see some charges come from this; not in a retaliatory sense, but because even though she loved her brother, she still had an obligation to LE when they came to her and wanted to see things. Unless there was something to hide, there is NO reason to not give over the data the detectives were requesting.
It will be interesting to see where the 7K ended up.
