So the guys that Joe Horn, Texas Vigilante, killed were actually illegal immigrants. Here's the news from Robert Crowe at the Houston Chronicle.
The article includes this mugshot of one of the deceased.
Illegals with multiple aliases and long criminal histories. These guys were no saints. The article goes on to mention that the criminals picked their victims based on the fact that the victims were immigrants themselves. That picking on immigrants would somehow make them "easier targets." Too bad these immigrants lived next to Joe Horn.
