Nine months worth of silent while pretending to want to not be silent raises questions.
And nine months worth of investigation doesn't raise concerns? If the authorities have evidence that a crime was committed, of what consequence is a statement from the suspect? How convenient that they are choosing to submit to the DA just days prior to the election. That is, assuming that they actually do so.
If I had any indications whatever that I was suspected of a crime, I would say absolutely nothing. Anything that I might wish to say could be said later. My advice to Ann would be to say nothing. What would your advice be?
