Photos: A Murder by the Border

Symbol
On March 27, 2010, Rob Krentz, 58, the scion of one of the oldest ranching families in southeast Arizona, was found dead on a remote part of his property after radioing his brother that he was helping someone whom he believed to be an illegal immigrant. Thus far, no one has been arrested for the crime. In the photograph above, Krentz's wife holds a framed picture of her slain husband and their dog.
