Q: Is possible he filed charges and did not tell me?
A: Yes.
Q: How would I find out if charges were filed?
A: Do what panther says.
Q: How long does he have to file charges (the total amount returned equaled $3,000 and I live in NC)
A: Since this is probably a felony, they may have 1 - 5 years to file. Ask a lawyer in your state for a correct answer. Mine is just a guess.
