From 2003 to 2014, part-time janitor and photographer Tom Kiefer worked at the U.S. Customs & Border Protection facility in southern Arizona. During his shifts, he noticed that items belonging to migrants who came through that facility were confiscated, and later, typically tossed into the trash. He couldn’t help but retrieve them. And then he began to photograph them. His powerful work is now on display at the Skirball Cultural Center in Los Angeles. You can read more about the photographer and his project here.
