Salvador Garcia Angeles portrayed in his bedroom in Azcapotzalco, Mexico on May 15, 2015. Salvador, 53, owns a stationery store in Mexico City, and has worked part-time for the past eight years as an assistant to his nephew, Donovan Tavera, a forensic cleaner. He says that his fastest cleaning –a suicide– took him 30 minutes to complete, and that his longest –a multiple homicide– took him eight hours. Donovan Tavera, 43, is the director of “Limpieza Forense México”, the country’s first and so far the only government-accredited forensic cleaning company. Since 2000, Tavera, a self-taught forensic technician, and his family have offered services to clean up homicides, unattended death, suicides, the homes of compulsive hoarders and houses destroyed by fire or flooding. Despite rising violence that has left 70,000 people dead and 23,000 disappeared since 2006, Mexico has only one certified forensic cleaner. As a consequence, the biological hazards associated with crime scenes are going unchecked all around the country. Photo by Bénédicte Desrus
