Wow, what a dumb ass to pull of a scam and use his educational email address.

If that is indeed his, which I'd suspect it is if he receiving funds from PayPal, contact his college:  College of Mount St. Joseph

I doubt the college admin and IT technicians will be happy about him using their services (email & perhaps internet/computers) to commit fraud.
They'll no doubt have full access to his email account along with backups of any deleted emails.
