Fire victim said he was stabbed by stranger

As I've mentioned a couple of times in these forums. I at the tender age of eighteen drove a wrecker for the local police in my town. I learned very well the art of pushing just the right buttons to keep us on an even keel.
I would get calls at one in the morning telling me there's a car sticking out the side of the church and we can't get at the occupants. You would think I had the upper hand, as They needed my special talents to accomplish thier objective.
Wrong, If I wasn't there ten minites ago there was a cruiser at my house. You see back then we didn't have the jaws of life, we had wreckers. I was part wrecker opperator, part emt, and part coroner. I was still in highschool.
I learned over time to gain the upper hand. You had to show them who was boss. Our downtown beat cop, took my car from behind the shop I was working at, because I left the keys in it. (they were having a big anti-car theft program at the time). He left it behind a local resterant frequented by the cops. It took me three hours to find it.
About three weeks later, I along with two friends pulled into a little variety store, right next to a cruiser that was left running just to grab a quick pack of smokes. To make a long story short I stole the cruiser. I drove it comletly through downtown ,and left it right in the same spot they left my car. With that little stunt I gained the respect of most of the cops I worked with. There was however one cop who is probably still pissed at me to this day.
Life went on and I still got those three am calls for a roll over or whatever. There were many days you would see a wrecker with a wrecked vehicle attached parked in the student parking lot. I did however keep the keys with me.
