Good freakin' luck. 
We have one that returns to us during all the warm months to eat the trash on trash day (townhouse neighborhood, pickup tues/fri mornings). It was about 2ft from me last summer, luckily pointed the wrong way and I scrambled into the house before it got me. NO LUCK GETTING RID OF IT.
1) Called police/animal control. Wouldn't come out unless it was "acting rabid".
2.) Called exterminators. Would come out for ~$500-$1000 depending on how long it took to catch, but told me "it's pretty much a lost cause, unless we can trap on the whole townhouse property, which would be HOA business, it's unlikely they're spending much time on YOUR property specifically".
3.) Called HOA. "Umm, we don't handle that. Have you tried animal control?"
ARGH. I'm expecting him back any day now. I hear they don't like mothballs, I may try that. Also, keep your grass cut, no food out...other than that, I never got much good advice. Hehe.
