How are crimes committed in three different counties (and two states) within a week's time handled?

By an attorney in each state and a defendant who travels (so long as he's not in custody). Your question is too general, asker.

Pretty good chance you do jail time on at least one if not all unless you get the same arty on all cases. We represent folks in TN and MS. There is nothing worse that when we only get retained on the TN , for example and not told about MS or vice versa. TELL YOUR ATTYS ABOUT EACH OTHER if you get two different, or God forbid, three different Attys. They will communicate with each other to facilitate the best possible outcome.

Defendant will be exterdited to the other jursidictions. Make sure his attorney knows about all the different cases.
