They'll need the survivors testimony, he may get a pass on auto theft.
Perhaps some of FR's attorneys can clarify. If the confrontation was at the time of the theft, this seems like relatively straightforward self defense. And the survivor could be charged with manslaughter or worse since the death was during the commission of a crime. But there was a two or three day lag before he found and recovered the car. Is that going to get him convicted? How about the survivor, can he be charged with more than auto theft?
The so-called “Justice System” has been turned into a game to be played by the lawyers to make them look a lot more important then they are.
