On cattle guard: Ag officer investigates crimes against livestock 

Scanning the laptop bolted to a stand in the cab of his pickup, Darrell Hale ran down the list of complaints. Topping it was a call about horses with oozing eye infections. The call was made to Hale's employer, the Arizona Department of Agriculture. He's one of nine livestock officers in the agency's Animal Health and Welfare Program, all reporting to the state veterinarian.
