Many families had expressed hope that law enforcement officers would be held accountable after a scathing Justice Department report in January detailed “cascading failures of leadership, decision-making, tactics, policy and training.” At an associated news conference, U.S. Attorney General Merrick Garland said lives could have been saved had law enforcement acted sooner. But just two months later, Uvalde residents said they felt whipsawed when a private investigator hired by the city cleared all local police officers of wrongdoing, even praising some of their actions.

Now, families anxiously await the results of the only remaining investigation: a criminal case brought by Uvalde District Attorney Christina Mitchell, for which a grand jury began reviewing evidence in January. It will determine whether any of the nearly 400 federal, state and local officers are criminally charged.
