This a Craigslist scammer. In this instance, he sent us a bogus check as an advance for work in the name of a company, requesting a portion of the payment be forwarded on to a PO Box. We called the company to see if it was real, which it wasn't, and they already had their local Sheriff's Office working on it. There had been at least 20 complaints already. Don't waste your time. Call the company on the check like we did so you can send any evidence to them and the officer handling the complaint. That way they will have a better chance of catching this con artist.
