I did a Google search for him in Washoe County but he didn't "pop" up.
There is no one way to find out if he's a resident that I know of.
You can look for him at www.whitepages.com
but if he doesn't have a land line you won't find him listed.
The Washoe County Library System, www.washoecountylibrary.us/
might have more ideas. Ask them or look for on the Internet a Washoe County Nevada County Directory or a Reno City Directory. I don't know how they get updated now but if you're looking for people a couple of decades ago they're helpful. Successful Searching!
