I lost my 91 k10 suburban about a week before Christmas. My boy was in the truck while it was warming up to take them to school. He forgot some homework, ran back into the house to get it, passing my wife on her way out the door. She was standing on the porch when they drove away, with a night's worth of Christmas shopping from the night before. After calling the law she called me at work, about 30 minutes away. When I got home I heard the story through her crying. I thought if things were anything like normal, there wouldn't be any gas in it. I started looking for it, was out about a half hour when I got the call they found it. When we went to pick it up a few blocks away, the officer there told us that one of people on the street had seen his neighbor messing around with the truck, it was parked across the street from his house. When the cop went over to talk to the guy,(Who unfortunately had a K5 for sale on his carport) he said he knew nothing about the Suburban. Then the cop asked if he could come in & take a look around, the guy agreed to that. No presents! But he had neglected to clear the scales & pot he had off the kitchen table. BUSTED! The officer said he knew the guy was involved, but couldn't pull any of his prints off the truck. The gifts were gone, and the only things missing from the truck were keys(house, other truck, mailbox,fun to replace stuff) and an amplifier that was one step this side of junk.
By the time I got back to work that day, the story was that my truck had been destroyed & ALL of our Christmas was gone. They had taken up a collection which more than compensated our losses, which I tried to refuse but they wouldn't allow it. I bought pizza for the entire building to try and ease my guilt. It probably was the best Christmas I've had since I was a kid!
About a week later my boy was driving past that house on his way to mine, he said there were two guys out front working on the Blazer. We took a ride over in the Suburban and did a couple of slow drive-bys. (No guns) From the reaction of the two guys on the carport they recognized my truck. About two weeks later, the house was empty & they were gone.
Things could have been a lot worse, but I learned a few lessons. Do not leave your rig running with the keys in it, no matter how long or close your going to be. And don't put any more keys on the ring than you want to replace if they come up missing!
