Finding Someone Who Owes You Money

[Ayodeji Kuponiyi]

I'm trying to find someone who owes me a large sum of money. They sold their house a month ago and their new address isn't showing up on Google when I search their name. The new owners do not know where he moved to and are trying to reach him as well since his old mail is still going to the old address. I told my lawyer to try to find him using Lexis Nexis . Any ideas?
