Scott Warren is a political geographer and a volunteer with the Arizona humanitarian organization No More Deaths. On January 17, 2018, Warren was arrested in Ajo, Arizona, along with Kristian Perez-Villanueva and José Sacaria-Goday, two Central American migrants to whom he was providing care. The United States has since charged Warren with two counts of felony harboring under 18 USC § 1324(a) and one count of conspiracy related to harboring. When combined, these charges carry a potential penalty of up to twenty years in prison. Following a seven-day trial in June 2019, a jury was unable to reach a unanimous verdict, resulting in a mistrial. The United States Department of Justice has decided to pursue the charges against Warren a second time, with a new trial scheduled to begin on November 12, 2019.
