Robin Reineke, director of the Colibrí Center for Human Rights, holds the personal effects of unidentified border crossers. Such personal effects are kept at the Pima County Office of the Medical Examiner in Tucson, Arizona, to match families with missing migrants who were last seen alive crossing the border. According to Reineke, from 1990 to 1999, an average of 12 remains of border crossers were brought into the Pima County Medical Examiner's office per year. From 2001 through the present, the average number of remains is 164. "There's been this discourse that security is the automatic obvious need on the border ... more walls, more border patrol, more surveillance, more unmanned aerial drones," she said. "That's the type of strategy that we saw change our landscape into one of death, and it's heartbreaking to see the same type of conversation happening now."
