That's crazy but yeh I was going to suggest the same. Maybe Home Depot can assist with their cams!
Can't believe how bold some people are to just jump in someones unlocked vehicle and start searching. That's pretty damn crazy!
Seems to happen a lot, too judging from stories I heard from friends and family. Only happened to me once - went to St. Pete Beach with my family and we were in a 2002 Chrysler Town and Country (nothing special) with doors locked. Obviously we must have placed our key in the beach bag and decided to walk around the corner to get a drink from a local beach bar while leaving our chairs, towels and beach bag out on the beach with quite a few people around us.
As we came back I realized the key was gone and checked the car - Key was still stuck in the lock and obviously someone had went through the items in the car as glove box was open and other stuff tossed around. There were no items of interest in there and no money so he didn't really get anywhere and we were happy the guy didn't steal the car

Of course as usual nobody saw anything!
A**holes!
