Do not call the police for firearms that you have that are not in your lawful possession EVER! Op’s friend needs to contact their executor and find out if there was any documentation naming inheritance for the firearms. Either way the executor or an attorney can advise her on what to do with them. I get that some people in this sub don’t like guns but having LE take possession of them without proper instruction could potentially land the possessor in hot water or cause them to miss out on a sale (should they go that route)that could net them thousands if it was a historical piece. There’s nothing worse than finding out you relinquished a piece for a $50 visa gift card that was worth $25,000 because you didn’t know any better. Or worse you get some nonsense possession charge because you are technically considered a prohibited person. Crazier things have happened.
