Donovan carries out a forensic cleaning in Iztacalco, Mexico on October 16, 2015. The decomposed body of a man in his 60s was found in his bedroom a number of days after he died of a heart attack – although the deceased's own family members were unsure exactly how long he had been there. The victim's family remarked that the police had made unfounded insinuations against them, and had sought bribes. As a result they found Donovan's discretion and professionalism to be a welcome contrast. 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

The scene of a suicide in the middle-class neighborhood of Colonia del Valle, Mexico City, Mexico on April 26th, 2016, which Donovan cleaned in three hours at a charge of $475. The 65-year-old deceased --who was HIV positive-- worked as a painter, and lived on the roof of the private psychologist's clinic where he had been receiving treatment for depression. His body was discovered in the practice three days after he committed suicide, when his psychologist was alerted by the odor and the presence of flies.

The 66-year-old victim was a retired economics lecturer from the local university, and was killed in January of this year. The cleanup took place eight months later. The victim’s family has since moved away to avoid further trouble. They remarked that justice is slow in Mexico and expressed dissatisfaction with the police investigation, but appreciated Donovan’s discretion and professionalism.

Cleaning formulas prepared by Donovan for a forensic cleaning in Mexico City, Mexico on January 14, 2016.

The bottles stand on a t-shirt outside the scene where the decomposed body of a man in his 50s was found on the floor of his mother’s bedroom, days after he had died of an intestinal obstruction. Because of her physical disability, the mother of the deceased – who had been her caregiver – was unable to move enough to make an emergency call. As a consequence, she was trapped in the room for three days with the body of her son – and without food or water - before help arrived.

The decomposed body of a man in his 60s was found in his bedroom a number of days after he died of a heart attack – although the deceased's own family members were unsure exactly how long he had been there. The victim's family remarked that the police had made unfounded insinuations against them, and had sought bribes. As a result they found Donovan's discretion and professionalism to be a welcome contrast. 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

Donovan's wife, Alicia, works at the scene of a suicide in the middle-class neighborhood of Colonia del Valle, Mexico City, Mexico on April 26th, 2016, where she helped Donovan with the clean-up. The 65-year-old deceased --who was HIV positive-- worked as a painter, and lived on the roof of the private psychologist's clinic where he had been receiving treatment for depression. His body was discovered in the practice three days after he committed suicide, when his psychologist was alerted by the odor and the presence of flies.
