Naughty Ava - The Kitchen Raider

Over the last several weeks we come home to messes on the floor, muddy paw prints on counters, dishes on the floor, and towels pulled off the counters. I decided to set up a camera to see which of my 3 puppies is being naughty.
After living 30 years with dogs and nothing having something like this happen, I am a bit beside myself as to the recent change in attitude, but the solution is rather obvious.
