To be honest, I know squat about the case outside of your OP. I just don't see how a boob job is circumstantial evidence. Strange behavior? yes. But for all we know she might express her grief through silicon. I am assuming there is more evidence than her behavior after her husband's death, or is that actually enough to try a case?

I like prosecutors btw. I have been informed by attny. friends that I should have been one. LOL
