The Twitter account is just repeating a Wordpress site's RSS feed. On that site, there's a link to .info, which according to a whois lookup was registered by someone at the "International Association of Healthcare Professionals" in New York. Google searches for that association reveal doubts of legitimacy[0] and scam warnings[1][2].
I haven't spoken to my friend or her father about it directly (I just noticed a tweet the other day) so I don't know if he was contacted about establishing a web presence or anything.
