Speaking to KENS 5 at the scene, the dead man's brother, Jose Garcia, said the truck owner was wrong:

“The victim was my brother and there are two sides to every story. Whether my brother was wrong or right, he had a gun pointed at him. I guess he took it upon himself to defend himself.

The guy who shot him is a vigilante, not a hero. A vehicle is not worth taking someone's life, I don't care what kind of car it is. You don’t take the law into your own hands. Now my mom, my family, we all have to suffer and just deal with it.”

The thief is lucky this wasn't the old days and he had stolen a horse. He might have been hung on the spot. ;)
