A pellet gun works great for us. Honey's used one to dispatch things from malformed kittens to full grown roosters. Hasn't tried it for a raccoon, though....those get the shotgun right off
Shoot it. Break/wring it's neck. Set up a euthanasia chamber with Co2. There are multitude of ways to dispatch a nuisance animal.
Do you really want it released next to your house? Giving the problem to someone else is irresponsible.
