I know it sounds rather backwoods but if you get those glass coke bottles, and stuff a few berries in them they make nice live traps. The Raccoons try to grab the berries with their hands but are too stubborn to let go so they basically flop around with a coke bottle arm making a bunch of racket. Then you can go out and snare em or kill them if you like. Just a thought you may want to try, since you said the coon was setting off your traps and not gettting caught.
