I had a similar thing happen to my car several years ago.

Kids in the neighborhood would wander around, checking for unlocked cars then riffle through the glove box, console etc. They would take guns, money or anything of value but had no interest in information. They usually just toss the papers in their way on the floor of the car.

It's pretty common nowadays.

Chances are if you check with your neighbors or the police you will find it happened to lots of people near you.

I got wind about the kid who did it on my street. Before I saw him again, he got arrested for a coupe other 2bit crimes and disappeared for good.

I leave nothing of value in my car but a little change in the ashtray and nothing is left unlocked.

Hope your situation is the same and nothing to worry about.
