Ok...got an idea that might help! Saw this in a movie once...but it was a police car (Hollywood Knights???) Can't remember which movie...but I think it is a sound principle...should work the same...in theory. Go down there late at night...closer to dawn actually...and tie their front door knob to someone's truck bumper... preferably someone who leaves real early for work! Try to hide the rope...use door mats, kids toys on the front porch, potted plants....etc. And then early the next morning...problem solved!
