When Warren’s trial kicked off in Tucson the following day, May 6, his fellow volunteers were still searching. They reported finding three sets of suspected human remains on Monday, another on Wednesday, and two more on Thursday. A majority were discovered within walking distance of a Border Patrol rescue beacon. All the while, the man the volunteers were searching for remained missing.
The bodies of nearly 3,000 migrants have been recovered in southern Arizona since 2000, according to the Pima County Office of the Medical Examiner. Aid group Humane Borders, which sets up water stations along migrant trails, said that may be only a fraction of the total death toll, with most bodies never recovered.
