On March 21, 2012 two South Korean foreign exchange students attending the University of New Mexico on student visas plead guilty to charges of disturbing an archeological site. On October 13, 2011, NPS employees at El Morro NM discovered two names “Super Duper Dana” and “Gabriel” illegally carved into the sandstone bluff also knows as Inscription Rock. After ascertaining that the monument visitor register included an entry on October 13, 2011 by a visitor who identified herself as Dana Choi for South Korea, a NPS law enforcement ranger initiated an investigation. Through Facebook, the NPS ranger was able to identify the defendants who subsequently were arrested on December 2, 2011 based on a criminal complaint. The students entered their guilty pleas under plea agreements that required them to pay almost $30,000 to the NPS to cover the costs of repairing the damage they caused to the monument.
