So sorry you had to experience such a miserable thing Op. I hope the collective community finds this scum. As a couple of others have suggested I would retrace every interaction in my mind with anyone who witnessed the pin in the garage. It could have been someone passing by when you unloaded the game from your vehicle, maybe a neighbor within line of sight, hell I wouldn't overlook the mailman until I had the game back in my possession. Hopefully the thieves are not in the position to play the long game and to them 3 weeks is an eternity. I wish you good luck in getting your game back asap!
