A Mexican army patrol confronts a group of armed suspects at a half-finished grain warehouse in southern Mexico. The Mexican army issues a statement saying troops came under fire, returned fire and killed 21 men and one woman while freeing three kidnap victims being held inside the warehouse. The Mexico State government and prosecutors' office issues a statement saying that forensics tests and crime scene evidence show the suspects died in "an equal exchange of fire" and there is "no evidence at all of any possible execution." The Associated Press and Esquire Latinoamerica publish the testimony of a witness — one of the alleged kidnap victims — who says 21 of the suspects were executed by soldiers after surrendering. The army issues a statement saying seven soldiers and a lieutenant involved in the confrontation have been detained and taken to a military prison on charges of disobedience and dereliction of duty.
