My son is selling my guns to pay for his drugs and he won't stop.

First off, I've already called the authorities and reported them stolen as I'm not a fan of illegal activities.<br>And I've already called the local gun shops and they know to contact the authorities if my son comes in.<br>I don't remember the specifics, but I think I have a Remington or Winchester model 70 being the most valuable.<br>The kid grew up around guns and has a good knowledge of them. He will know how much is missing.<br>I think there might be some gaps in the stories given to the authorities by my son and myself. Missed details as I'm not a fan of the police.<br>I know it's wrong, but the kid is fucking up and I want to know what's going on while still keeping the police informed.<br><br>But how do I keep the kid from figuring out what's going on? He's also very capable of manipulation.
