This award-winning documentary depicts the true story of a man who died crossing the U.S.-Mexico border and who was identified by the efforts at the Pima County Office of the Medical Examiner and the Colibrí Center for Human Rights. A unique clue reveals his identity, and those who come into contact with him tell a human story that challenges the walls, divisions, and border that currently characterize the immigration debate.

  • Starting in the 1990’s, the federal government implemented “prevention through deterrence” policies that put the lives of migrating people at risk by pushing them into areas of the border where  “mountains, deserts, lakes, rivers and valleys form natural barriers to passage.” The strategic plan also spoke about “the searing heat of the southern border” and said that, “[people] crossing through remote, uninhabited expanses of land and sea along the border can find themselves in mortal danger.”

  • Colibrí currently has reports for more than 3,000 missing people last seen crossing the U.S.-Mexico border. We have sampled more than 583 individual family members for DNA in the hope of helping them find answers about their loved ones.

  • Between 1990 and 1999, the average number of migrant deaths in Southern Arizona was 12. From 2000 to 2017, that number spiked to 157 deaths per year. Between 1990 to 2017, the Pima County Office of the Medical Examiner examined 2,939 individuals who died crossing the border in Arizona.

  • More than 60,000 migrants have died worldwide since 2000. The deaths and disappearances of migrating people is a global human rights crisis.

  • U.S. Border Patrol recorded more than 7,216 recovered remains of assumed migrants between fiscal years 1998 and 2017. These numbers are considered by many experts to be a low estimation of the actual number of deaths in the borderlands.

We partner with families and forensic scientists to find missing people and help identify people who have lost their lives on the border. We collect detailed missing persons reports as well as DNA samples from families searching for missing loved ones. We then work with medical examiners to compare this information to that of unidentified individuals.


The Family Network is a community of mutual support and solidarity between families and friends of migrants who disappeared while attempting to cross the US-Mexico border. It is a space in which families of the disappeared can come to know others going through the same difficult situation, building a network of trust and support as they wait for answers and navigate the many obstacles of the search.


Historias y Recuerdos is a testimony project where families reflect, remember, and share stories about a loved one who is missing on the border. These stories are powerful, both in the experience of sharing them and in that of listening to them. They demonstrate how unique and irreplaceable each individual human being is and serve to raise consciousness about the human rights crisis on the border.
