The journey of many migrants in search of a better life ends in a freezer in the morgue of Tucson, Arizona.
Unidentified bodies from the year 2000 of people who died trying to cross the border have been piling up in the Pima County coroner's room.
Despite efforts to identify the bodies recovered in the desert, the vast majority end up in anonymous columbariums in the county cemetery, while their belongings are stored in airtight bags, waiting to shed light on the identity of their owners.
In southern Arizona, where weather conditions are extreme, migrant apprehensions continue to rise.
To try to reduce deaths, help buttons have been set up in the Sonoran desert, where migrants can ask the Border Patrol for help, even if it leads to their arrest.
