Yes, he uses untraceable numbers, ie: prepaid cell phones. Also, the only thing moneygram can tell me about him is that he picks up his cash in Raleigh, NC. The only thing I've heard is that it might be possible to intercept him when he goes for a pickup. But I think the fact that you have moneygram waive the ID and ask the security question covers his tracks.
This guy uses the names Bill Thomas, Tom White. He is advertising about a escort driving position, He will go over local regulations as well as what he looks for in drivers. He then tells you that a deposit is required and asks you how soon you are ready to go to work. After he gets your deposit you will never hear from him again.
He got me too. I'm out $690 and never heard from him again. I never thought it was a scam because it was so elaborate. He went into so many details. I'd like to talk to someone about this and hopefully bring the authorities in on this.
