Posted Lt. Rex Bishop By John Underwood / john@gulfcoastmedia.com ROBERTSDALE, Alabama — Exactly 39 years to the day he put on his first official officer’s uniform with the Loxley Police Department, Rex Bishop, now a lieutenant who has served the last 17 years as chief investigator with the Robertsdale Police Department, is retiring. “It’s been a very rewarding job,” Bishop said, “helping take criminals off the street, particularly when those criminals hurt children. I’ve worked a lot of cases over the years involving children and when I can be involved in getting children out of harm’s way, that has been the most rewarding.”
