This Is A Trial Made For Texas Monthly

I know very little about this McKinney murder case but this reporter's Twitter feed got my attention. The case seems beyond interesting -- especially, from a legal standpoint, when I learned there is an agreement to cap the sentence at 50 years in exchange for the Defendant telling authorities where the body was. (The max otherwise would be Life.) I guess that can be done by agreement and with the judge's approval, but I've never heard of it. And the prosecutors bringing it up in front of the jury, unless I'm missing something, puts them on shaky ground.
