Original story and thread from back in April:
Bad: Taco Bell shooting victim holding leash when shot
Guy is in the drive-through at a Taco Bell in Phoenix with his pregnant girlfriend. A guy walking his dog stepped in front of the first guy's vehicle, causing him to slam on the brakes. From there it degenerates into he said-she said; lots of yelling, guy in car said he saw a bat or similar weapon, said he feared for his life, drew his weapon and shot the dog walker, killing him. No weapon was found, and the dead man was somewhat mentally impaired, with the mental capacity of a 12 year-old.
Now the shooter has been charged with 2nd degree murder:
