Handguns must be registered in New York state.

You must have a concealed carry permit to possess a handgun anywhere in New York state. Placing them in locked declared luggage would have satisfied Federal transport rules except that he was not lawfully permitted to be in possession of the handguns in New York state.

The jail at Rikers Island is in New York City, so it's also likely that he was stopped at a New York City airport, and you're in violation of New York City law as well.

It's likely that New York state law restricts transfers (even inheritance) to those with permits, and requires use of an FFL to do so.

The action type would not matter. The fact that he was in New York in possession of a handgun was a felony violation of their state law.

You don't need the advice of an online gun forum, you do need a competent New York lawyer that is familiar with their gun laws. Prepare for some breathtaking expenses.

Start with a lawyer you're familiar with in your local area and seek a reference.

I would advice against listing your personal email on the forum.
