There are basically two aspects of your problem. Firstly, you will either try to recover your money from your friend's parents, which would not be a justice. Secondly, Your friend is in USA so can file case against him here, but you will not be able to get any fruitful result because he is not in india right now. The choice is yours.
For any further assistance, feel free to contact me on my e-mail "firstname.lastname@example.org"
