Rodrigo Diaz Mejia climbs over a crushed car into what was a second-story apartment at 517 Tokio street, felled by the earthquake almost one month ago in the Portales Norte neighborhood of Mexico City, Wednesday, Oct. 18, 2017. The 38-year-old mechanic who lives nearby said he ran to help rescue people trapped atop the buildings roofs on the day of the quake, Sept. 19, and has since been making risky trips into the ruptured structures to retrieve valuable possessions for displaced residents.
