"Looks like"? Where are you getting this information? Were you in contact with him recently?
Guess since he likely turned away i could say what he told me. He told me his grandpa has cancer and knowing the US health system it was an explaination to me why he needs money and doesnt give it back. Though when he tells other stories to other users then this most probably is not right.
Yes, people can be saddled with debt for hospital bills but even in USA you don't have to pay up front for care. I think you're right that he's just offering up excuses. Very sad situtation in any case.
