Online tracing of a U.S. citizen in the USA

whats the best way to trace someone in Florida online please?

There are a lot of people search engines online, just to name a few:
http://www.whitepages.com/
http://www.whowhere.com/
http://www.peoplefinder.com/

even try google.

However, if they don't have a phone and the none of the other searchs are productive, you can contact a Private Investigator. Generally they have connections that can find people and it isn't that expensive.

One of the cool things about Florida is that all Counties are required by law to make their public records searchable online for free.
Do a Google search for "----- County Florida Public records". If they have ever owned property or had any legal documents filed
with the county they will be online. Many of these documents will contain addresses and phone numbers.
If you want kick me a PM and I'll give more info.

Zabasearch has worked for me

What if this person doesn't want to be found, wishes to preserve their privacy in an age of google stalker colonics?

Want in one hand, shit in the other - see which one fills up first.

Depends upon how much peanut butter was blown up my ass by a naked pygmy. In a clown suit.
