Artificial intelligence can be used to provide a more precise time of death, which could be crucial in murder investigations. The method was developed by researchers at Linköping University and the Swedish National Board of Forensic Medicine who have trained an AI model on metabolites in thousands of blood samples from real deaths. "Death is a strong biological signal," says Rasmus Magnusson, postdoctoral fellow at the Department of Biomedical Engineering, IMT, at Linköping University, who led the study published in Nature Communications in which AI is used to determine the time of death.
