Kimberly Rubio, whose daughter, Lexi, was killed at Robb Elementary, said the district was right to fire Elizondo, but said she shouldn't have been hired in the first place.ABC News confirmed Wednesday that Elizondo, a former Texas state trooper now under investigation for her conduct in responding to the Uvalde school shooting rampage, was among the new officers hired for the Uvalde school district police department -- the same force that has come under fire for the bungled response to the massacre.The seven have been suspended, however, by Elizondo resigning from DPS to work for the Uvalde schools she is no longer subject to any internal discipline or penalties.Texas DPS said Thursday it sent a memo to the Uvalde school district on July 28, which was transmitted on a secure law enforcement network on Aug. 1, saying that Elizondo was under investigation by the DPS inspector general.Some have called for the creation of national standards and databases that would enable prospective employers to learn quickly whether a cop has anything potentially disqualifying in their employment history."
