Zapopan, Mexico (AP) – First scientists wear dead boar clothes in cloth, then they dispose of bodies. Some they wrap in packing tape, others they cut. They fill the animals in plastic bags or wrap them in a blanket. They cover them in lime or burn them. Some are buried alone, in other groups.
Pigs are playing an unexpected role in research as a proxy for humans, helping to find a shocking number of people who have gone missing in Mexico during drug cartel violence for decades.
The missing families are usually left to search for their loved ones with little support from the authorities. But now, government scientists are testing the latest satellites, geophysical and biological mapping techniques – with pigs – to offer clues to offer that they hope at least some bodies may be discovered.
The rank of Mexico’s disappearance exploded after the launch of the war of the then President Felip Calderone against drug cartels in 2006. A strategy that targeted the leaders of a handful of powerful cartel, which led to a multiplication of organized crime and violence to control the multiplication of organized crime and violence.
With complete impurities, due to the complexity or inaction of the authorities, the Cartels found that anyone feels that they disappear in their own way, it was better to leave the bodies on the road. The Mexican administration is never ready to identify the problem and in other times the scale of violence is stored, their justice system is not ready to address.
The disappearance of Mexico can settle a small city. The official data in 2013 went missing 26,000, but the count is now more than 130,000 – more than any other Latin American nation. The United Nations has said that there are signs that disappearance are “generalized or systematic”.
If missing people are found – dead or alive – this is usually done by their loved ones. Witnesses, parents and brothers -in -law, discovered the tombs by passing through the information directed by information, sink a metal stick in the earth and smell to the smell of death.
Since 2007, around 6,000 cladstine graves have been found, and new discoveries are made all the time. Thousands of remains have been identified so far.
Jalisco, which is the home of Jalisco New Generation Cartel, has been reported missing in Mexico: 15,500. In March, hundreds of items of human bone and clothing were discovered in a cartel farm in the state. Officials denied that it was a collective tomb site.
Jose Louis Silvan, a coordinator of the mapping project and scientist in Central, focuses on a federal research institute, geophysic information, said that Jalisco has disappeared “Why are we here.”
A collaboration by the Mapping Project launched in 2023, the University of Gwadlajara, National Autonomous University in Mexico and Oxford University at England, with Jalisco Search Commission, is a state agency, organizing local discoveries with relatives.
Comori of Canadian Forensic Anthropologist Derek said, “No other country is so strongly, so no one is moving forward”, a Canadian forensic anthropologist Derek’s Comjums said, whose geographical information systems specialized in the geographical information systems inspired the Mexican project.
Nevertheless, the Comjum warns, technology is “not a panacea.”
“Ninety percent of the discoveries are resolved with a good witness and excavation,” he said.
Silvan runs from a site where scientists buried 14 pigs about two years ago. He says that they would not know how well the technology works, where and when it can be used, or under what circumstances, for at least three years.
He said, “Flowers came out due to phosphorus on the surface, we did not see last year,” he said that he had measured one of the tombs. “Mothers who find, say that small yellow flowers always bloom on tombs and they use them as a guide.”
Pigs and humans are closely related, famous 98% of DNA. But for the mapping project, physical similarities also matter. According to the US National Library of Medicine, pigs are similar to humans in size, fat distribution and skin composition and thickness.
A large colombian drone flies on the mounted pig buried site with a hyperpactral camera. Generally used by mining companies, the camera measures the light reflected by substances in the soil, including nitrogen, potassium, phosphorus, and shows how they differ as disruptions of pigs. The colored image that it produces provides clues of what to see in hunting for graves.
“This is not pure science,” Sylvan said. “This is science and action. Everything learned is to be implemented immediately, instead to wait for it to mature, because there is urgency.”
Researchers also appoint thermal drones, laser scanners and other gadgets to register discrepancies, underground movements and electric current. A set of graves is attached to a pane of transparent acrylic, which provides a window for scientists to observe the decomposition of pigs in real time.
The Jalisco Commission compares and analyzes and analyzes flies, beefs, plants and soil recovered from human and pig graves.
Each grave is a living “micro ecosystem”, Tunuari Chavez, director of the commission of reference analysis, said.
In 2014, the disappearance of 43 students triggers, Sylvan and their colleagues began gathering information about ground-entertainment radar, electric resistance and satellite imagination from around the world. He studied the University of Tennessi Research on Human Corpses buried in “Body Farm”. He saw the tomb-maping techniques used in Balkan, Colombia and Ukraine.
“What is good if it does not solve problems, then what is good?” He said.
He learned new applications of satellite analysis, then began his first experiments buried by pigs and used for the disposal of bodies while studying criminals of substances. They found that lime is easily detected, but there are no hydrocarbons, hydrochloric acid and burnt meat.
Chavez’s team worked to combine science as to what they knew how cartel operated. For example, he determined that the disappearance in Jalisco usually occurred with Pacific ports, drug manufacturing facilities and cartel routes between the US border, and that most of the missing missing are found in the same municipality where they disappeared.
The experience of missing families also informs research.
Some saw that tombs are often found under trees whose roots grow vertically, so people digging the tombs can remain in the shade. Silvan stated that the mothers of the missing loved ones invited by the researchers to go to one of the pig buried sites were able to identify the most unprecedented tombs alone, because due to plants and soil placements, Silvan said.
“Knowledge flows in both directions,” he said.
Maribel Cedino, who has been looking for his missing brother for four years, said that he believes that drone and other technology would be helpful.
He said about his discovery, “I never imagined being in this position, finding the body, becoming such an expert,” he said about his discovery.
Héctor Floors is looking for his son from 2021. He questions why so much time and effort have been invested in ways that have not led concrete discoveries, when families have proved a track record with very little official support.
Although the research has not yet ended, the Jalisco Search Commission is already using a thermal drone, a laser scanner and a multisactral camera to help families seek their missing relatives in some cases. But it is not clear that officials across Mexico will ever be ready to use, or will be able to tolerate high -tech colleagues.
Forensic scientist, K Constance said that researchers are aware of the boundaries of technology, but that “you always have to try, fail, have to fail again and have to try again.”
