Garbage issue

I live in a 4 plex, we all pay for our own garbage can. We have this entitled "Princess" thst won't ststoputting her garbage in our cans. All cans have apartment number in big letters on top. Yesterday another neighbor took out this persons garbage fromnher can and then placed it next to the "princesses" can, this time there was mail in it and you could see their name. Gotcha! My question is this, to teach her a lesson would you report it for illegal dumping? Its her name, but a different city address... in my city and county my good neighbor said you can report online. Now this is the same tenants thst has a dog not allowed because its a dangerous breed, yelled at me saying "you better tell your ugly ass daughter to stop putting garbage in my csn" and then went to saying "I hope you die soon from your cancer". Then I get a note on my car from someone saying he saw the tall guy thst lives in our complex slash a tire on one of our cars.. and my tire was slashed. I also have a security recording of her saying what she said, its in my back yard and I have security camera back there. She won't say anything out front because we both have a camera. She doesn't know about the one out back. WWYD?
