(Murphysboro, IL) — The Murphysboro alderman who pled guilty to sex abuse charges has officially been replaced. Tom Ridings was chosen to serve out the last two years of Ronald Nolan’s term. He’ll have to run for election if he wants to keep the job longer than that. Nolan got in trouble with the law early last year after riding around with a Carbondale woman in his car, against her will.
