AUSTIN, Texas (AP) — A criminal investigation in Texas over the hesitant police response to the Robb Elementary School shooting is still ongoing a year after a gunman killed 19 children and two teachers in Uvalde. Wednesday marks one year since the deadliest school shooting in Texas history. The continuing investigation underlines the lasting fallout over the shooting and how the days after the attack were marred by authorities giving inaccurate and conflicting accounts about efforts made to stop a teenage gunman. The Uvalde school district permanently closed the Robb Elementary campus and plans for a new school are in the works. Schools in Uvalde will be closed Wednesday.
