In this June 4, 2013 photo, Lenin Carballido poses for a portrait during his campaign in Oaxaca, Mexico. Mexican prosecutors are investigating how Carballido certified as dead was elected mayor of a village in southern Mexico. Carballido narrowly won Sunday's election in San Agustin Amatengo, near the colonial city of Oaxaca. But then a death certificate surfaced, indicating that Carballido had died in 2010 of a diabetic coma. Prosecutors say one of Carballido's relatives used the death certificate to convince detectives to drop an arrest warrant for an alleged 2004 rape. (AP Photo/Luis Alberto Hernandez)
