Despite what you hear about in the news regarding big data breaches, the single most common way people have their identities stolen is through their mailbox. The second most common is through your glove box.
You likely have some local meth heads either looking to steal identities for their next fix, or worse, they're acting as mules for organized crime in return for their particular vice, and aren't smart enough to realize it.
So often when we are dealing with identity theft, it's really hard to hold a person accountable for the crime. One of the most frustrating things I see when walking into a courtroom is a victim coming in with a big stack of papers detailing everything they've had to deal with, and regardless of what happens in the courtroom, they leave a victim. More often than not, it doesn't make it that far because most local police departments don't have the skills or manpower to track the perps down, so they avoid even taking a report on something that will wind up contributing to unsolved crime statistics.
The moral of this story, is it sounds like you may have the unique opportunity to help everyone out by getting some bad guys off the street. If you get pictures with a trail cam or similar, I know some guys who would be awfully interested in busting some mules and making an example of them. Location is everything with the camera, don't put it in the mailbox, but close by with a good view would be ideal.
Good luck.
