Gerardo Jarquin Diaz, mayor of the small town of San Pedro Totolapan and member of the PRI (The Institutional Revolutionary Party), was arrested for killing one supporter of the rival political group PRD (Party of the Democratic Revolution) and injuring another. The shooting took place after the two men made fun of the PRI’s performance in a recent election. The election results mark the first time that the southern state Oaxaca has been ruled by a non PRI governor in 80 years.
