On 19 September, a 7.1 magnitude earthquake struck Mexico, the most devastating in a generation.

One office block in central Mexico City - Alvaro Obregon 286 - is the deadliest site, with over 35 bodies recovered and more still missing. Families camped out for days as they waited for news of their loved ones, as dozens of rescuers searched the rubble.

The BBC spent three days with the family of 26-year-old Adrian Moreno, who had recently started working in the building.
