Amid the police department suspension, the district said it's requested more Texas Department of Public Safety troopers to be stationed on campuses and at extracurricular activities, adding, "We are confident that staff and student safety will not be compromised during this transition."Hernandez acknowledged in a law enforcement communication in August that he'd received formal notification from DPS that an officer applying to Uvalde's school police force was under investigation for her response at Robb Elementary.The seven were suspended, however, by Elizondo resigning from DPS to work for the Uvalde schools she was no longer subject to any internal discipline or penalties.The school district said in Friday's statement that "decisions concerning" the school district police department have been pending results of investigations from the Texas Police Chiefs Association and the private investigative firm JPPI Investigations, but "recent developments have uncovered additional concerns with department operations."Results of the JPPI investigation "will inform future personnel decisions" and the Texas Police Chiefs Association's review "will guide the rebuilding of the department and the hiring of a new Chief of Police," the statement said."
