That happened to us when we first moved in, they broke in 3 times, first time they ripped off all the cabnet doors, shot the fire extuingisher everywhere, and rode bikes around, second time they broke holes in most of the walls, smashed windows, and stole my dad, my mom, and my laptops, my phone, and my skateboard. Third time we were to smart, we had bolts, and solid oak doors, because they had smashed some of the doors, they did kick in the back garage door, but the cabnets were empty, the doors were still off, they couldnt get in any room, and they set off my little tripwire alarm i set, they got arrested, still never found our stuff :/
Also, maybe they knew that you were to almighty epicness to even attempt it?
