Motor Home Parks are interesting places - they are more informal neighborhoods so everyone tends to know everyone else... and there are rules for anyone getting in - having to pass security profiles, just like apt. buildings. HOWEVER, this informality is a double edged sword: the double and triple sets of eyes keeping tabs on what sometimes can be the "extended village family" of years ago, in some MH cases can backfire.
I would wonder why this MHpark did not kick her out in January. They are well within their rights to have done so. Then again, this MHPark kept Wohler around, after he inappropriately kissed Sandra in the pool when she as a 6 y.o. So this MHPark OWNERSHIP is worth a gander.
Kicking someone out of a MHP doesn't have anything to do with whether any police action came to fruition or not, any MHPark can kick anyone out for violating ITS code of conduct rules. I sure as heck hoped that kissing a 6 y.o. followed up with a police complaint was reason enough, because the attitude of laxity "hey look what Wohler got away with - betcha I can get away with pedo stuff in Pedo park" - would be enough to encourage other slimeballs. Zero Tolerance on Pedo Acts, and kissing a 6 y.o. child on the lips is a pedo act IN MY BOOK. My neighbors that I know aren't allowed to do that fer kwise sakes and we ALL know that.
I believe, as I understand it, Melissa Huckaby moved in with her grandparents, who already lived at the mobile home park. In all likelihood, Melissa never had to apply to live there. If there was even any question, since the grandparents were in good standing in the community, perhaps they simply said she and her child were their guests. I doubt if anyone in a such a mobile home park would be clocking how long someone's relatives were staying if the relatives weren't overtly a continuing problem.
In the Jan. incident, the child apparently made no complaints or accusations, and I do imagine that the hospital would have checked her out for sexual abuse under the circumstances. As the detective said last night on TV when asked about this previous case, they had no probable cause to arrest Huckaby because of the time factor. Since no one there seems to have known anything about Huckaby's history then, it's possible that the Park managers wouldn't have known they had any grounds to evict Huckaby.
Look at the neighbor Sinclair: he has been reported as having a history of domestic violence. Was this violence done elsewhere, or at the park? In either case, if they did extensive background checks and were strict in their policies, I doubt he'd have been there still.
I'm not sure about Ca. law in this, but it's not as easy to evict property renters as you might think, either. It's very expensive to go through the legal steps and can be very contentious and time comsuming, as well. Landlords do get attacked and/or robbed all the time. Dealing with the public literally where they live is tricky, make no mistake about that.
Just some thoughts about your ideas.
