Here’s my take...
—If he’s pleading then it means the sentencing range he’s being given will allow him to walk out some day. If not, he’d take his chances with a trial. He’s 42, so I’m guessing his lawyer and the prosecutor probably plan on 20-25 years (the judge ultimately decides). Also remember that there’s no parole on federal sentences, but they do get 15% off for good behavior. So unless he gets into trouble he’ll only serve 85% minus however much he’s already sat in the county jail (I’m too lazy to look but I’m guessing a year?). I’d bet money he’s walking the street in 16-ish years give or take one or two.
—No, I’m not a lawyer and I’ve never been involved with the federal courts in any way good or bad. Take my viewpoint or leave it, but I bet this is what happens.
