Tough case to quack?!?!
Sounds like a prank that High Schoolers would do. Seems like real criminals do the stealing for gain. HS kids tend to do things that are deemed funny in their opinion. The garbage pickup thing probably gave the teens a real unexpected laugh!
Too bad though. Most lawn ornament things seem to be the property of senior citizens. I hate to see things like this happen to seniors. If it was HS kids, then it will get out eventually. HS kids do pranks, but they also have trouble sealing their lips.
