On July 9, 2005, two No More Deaths volunteers, Daniel Strauss and Shanti Sellz, were arrested by a Border Patrol agent while transporting three immigrants from the Arivaca "Ark" to Tucson for medical attention. The migrants were allegedly suffering from severe thirst and hunger due to vomiting as well as blisters that prevented them from walking. Sellz and Strauss were charged with transporting migrants and conspiring to transport migrants, both felonies under US federal law. If convicted, they would have each faced up to 15 years in prison and a $500,000 fine. Lawyers for the defendants argued that the aid workers were not transporting the immigrants "in furtherance" of their being in the country illegally, and therefore were not guilty of smuggling. US Magistrate Bernardo P. Velasco disagreed and refused to dismiss the case. No More Deaths responded with a campaign called "Humanitarian Aid is Never a Crime" to raise awareness about the case and persuade Judge Raner C. Collins to overrule Velasco and drop all charges. They distributed hundreds of bumper stickers and yard signs to supporters, and over 5,600 people (including the Episcopal Bishop of Arizona) signed a petition in support of the two humanitarian aid workers. Judge Collins dismissed all of the charges against Sellz and Strauss on September 1, 2006. The judge stated that at the time of their arrest, the two volunteers were following a protocol that had been previously established by the US Border Patrol and No More Deaths. Judge Collins stated that Sellz and Strauss had made an effort to ensure that their actions were lawful, and that “further prosecution would violate the Defendants’ due process rights.” On April 22, 2007, Sellz and Strauss were awarded the Óscar Romero Award for Human Rights for their work with No More Deaths. The $20,000 award, presented by the Rothko Chapel in Houston, Texas, is "presented periodically to persons or organizations who distinguish themselves by their courage and integrity in defense of human rights." The two human rights workers each accepted $5,000 and gave the remaining $10,000 to No More Deaths. On September 3, 2010, the littering conviction of Daniel Millis, for leaving water bottles in 2008 for immigrants crossing through a desert wildlife preserve was overturned by a 2-1 appeals court decision. In 2018 migrants were in the news as President Trump threatened to send the U.S. military to close the border and stop the Central American migrant caravans. In January 2018, Scott Warren, a volunteer with No More Deaths, was arrested and charged with a felony for harboring migrants after Border Patrol allegedly witnessed him giving food and water to two migrants in the west desert near Cabeza Prieta.
