This quickly? With this much evidence, I can't imagine it being remotely possible, and it's a hair early in the sequence too..
But now that it's required, the sooner the better imo. Any talk of a deal won't come until the defense attorney has weighed the evidence and can advise his client properly on any offer. That "weighing" is likely to include a closer look at tests that say something, or at witnesses who said something.
I think the next real domino to fall with EA will be a negotiated deal in the SA case (instead of a trial). IMO both sides have too much they'd risk, and not enough of an upside, to take that case into a courtroom battle. LE's evidence is strong that he committed the crime (the list of witnesses who have said he did it is essentially everyone who might have known, including his own words), and their trump card is that if EA went to court instead, any sentence where he was given some sort of "probation" would end up with that probation instantly revoked (in light of his arrest on another felony that occurred after the SA).
