STORY: "It was the duty of Morelos' prosecutors' office to carry out the investigation," she said. "Without the intervention from Mexico City prosecutor's office, this femicide would have gone unpunished."
Morelos' attorney general had said the autopsy of the body of Ariadna Lopez showed no evidence of violence and that the 27-year-old had died of alcohol intoxication, but an investigation by Mexico City prosecutors later concluded she had died of multiple force trauma.
Sheinbaum's comments came as protesters took to the streets of Mexico City on Monday to demand justice for the victim.
Hours later, Morelos' state anti-corruption prosecutors' office said it had launched an investigation into the state attorney's office, over "possible crimes" committed by employees of the attorney's office during the investigation into Lopez's death.
