Can any Warrior help me stop this google bombing jerk?

So happens a new company I'm working for, the company brand name is also the owner's name. The owner had a past client relationship with a mentally unstable person who has and continues to post the same false accusation against our company owner on multiple different websites across the web that have decent pagerank.

I've know the owner for a long time prior to comming to work for him and can no for a fact he would not do what this insane person has accused him of doing. The problem we now have is that when someone types in my company owner's name the first page of results has listings from scam dot come, rip off report dot come, etc, etc. This guy basically copied and pasted his rant on multiple, multiple websites. Somehow he has a little knowledge of pagerank/seo I think or he's just darn lucky.

We've started to agressively push more content out on the web with the owner's name in the title and in the content body in efforts to hopefully push this guy's rantings off the first page - dunno if that will work or not.

I wondered if there were a way to communicate with Matt Cutts or someone directly, as this really is search engine spam/duplicate content and simply a man on a mission to ruin another man's business and character online. He's nothing more than a bully wannabe but unfortunately their seems to not be a hall monitor present on the search engines so he's just continuing his destructive behavior.

The owner considered filing a lawsuit at one time but he is a Christian man and he felt spirtually convicted about this subject and felt compelled not to file suit despite the continued harrassment.

Just wondering if you have any tips, advice, or know of anyone besides George Bush who's encountered a negative google-bomb attack like this and any resources for effectively combatting it?
