Politics intruded almost immediately after searchers finally found the body of Robert Krentz on March 27, next to the carcass of his slain dog. Krentz was a rancher living practically on Arizona's border with Mexico and the suspicion was that he was killed by illegal immigrants. No one has yet been arrested in his murder, but that hasn't stopped him from becoming the focus of a rallying cry for activists and politicians calling for a tougher crackdown on border security and illegal immigrants. Like Krentz's murder, the disappearance of David Hartley in the Texas-Mexico border area quickly became a cudgel for Texas Governor Rick Perry in his re-election campaign. On Sept. 30, Hartley and his wife Tiffany, 29, were taking a jet-ski tour in Mexican waters around the submerged village of Guerrero when, Tiffany told Texas law officials, her husband was shot and killed by armed men, so-called pirates, in three fishing boats. His body has yet to be recovered; about two weeks later, the lead Mexican investigator in the case was found beheaded, his body stuffed in a suitcase that was left in front of a military base.
