It had already been suggested by other researchers that the gastrointestinal contents of maggots could be used to identify the subjects they feed on. However, never before has the theory been trialed in a legal, criminal case. Pathologists at Autonomous University of Nuevo León in San Nicolás, Mexico, led by María de Lourdes Chávez-Briones and Marta Ortega-Martínez, carried out short tandem repeat typing tests (a common method of DNA profiling) on the matter extracted from three dissected maggots found on the victim's face and neck, and separately on the alleged father of the missing woman. Preliminary results showed that the body was female, and the final outcome was a 99.685 percent probability of positive paternity—the victim had been identified.
