Suspicious in suburbia

So, our yellow lab, Dakota starts barking and going nuts about 4 a.m today. My husband looks out the window and sees our neighbor's car in his driveway. We all fall back asleep. This morning we awaken to a fresh lawn job and run down bushes in our front yard. Neighbor across the street has tire tracks buried in his lawn as well. Next door neighbor's car is smashed in by front passenger side door and grass is stuck in it. hmmmm??? Husband asks NDN how he's feeling and he says he has a hangover...doesn't know anything about tire tracks in lawn, although there's clearly tracks running from his driveway, into his grass, then into ours. Wonder if incident has anything to do with wife & kids in Korea for two months.
