1. If dude has friends in your parents state and he can connect dad's phone number to his unoccupied address....
2. There's a scam going via Craigslist where a perp replies to a for sale ad, asks for your cell phone number, then eventually asks for your direct email (outside the CL anonymizer). Perp then sends an authentication code from your email provider (Google is a very popular throw away) then asks you for the code to "confirm that you are not a scammer". The perp then uses the code to gain control of your email account and tries to reset your passwords at financial institutions. <br><br>Complex but apparently real. <br><br>
