Hmmmm...I wonder who gave her that lead? That should prove very interesting...
I'm thinking the local rumor mill. Or a court officer upset about the secrecy in the first place, inflamed by seeing Scott's mug on TV.
I wonder if the sealing of the file wasn't improper in the first place, we would ever have heard this story. That is, the first stories weren't so much about Scott, but the local news about the DA firing a long-time assistant DA because of the apparent impropriety of the process, rather than the crime itself.
Another station has news about prior indicent(s). This sounds like local LEO spilling the beans, maybe with some schadenfreude towards the DA's office.
