Well, we scratched our heads and commisserated with each other. My hubby is retired Detective from VA, one victim is a single lady of Hispanic name, other neighbor from Mass, and the last house is a rental with no-one home. If the perpetrator(s) are kids, they are TALL kids, as the light fixture tops were removed, then smashed, along with the light bulb - ie, someone tall enough to manage that feat (not me, I'm 5.2") Perhaps its those Early Bird Special Two-fer drinks goin down on the square?......
At least its only light fixtures. When hubby worked it was in a high crime city and MUCH more deadly events. We won't sweat the small stuff.
