Uvalde mayor calls on district attorney to resign, accusing her of a 'cover-up' in the Robb Elementary shooting investigation

The mayor of Uvalde, Texas, is calling on District Attorney Christina Mitchell to resign and has filed a lawsuit accusing her of repeatedly obstructing the city's investigation into the shooting at Robb Elementary School last year that killed 19 students and two teachers. \Fifteen months have passed since this tragedy and I feel our families and community deserve answers,\ Uvalde Mayor Don McLaughlin said in a written statement attached to a lawsuit filed Tuesday.

McLaughlin alleged that Mitchell was involved in a cover-up related to the city's investigation into the Robb School tragedy.

Mitchell told the San Antonio Express-News on Tuesday that he is still reviewing the evidence but plans to present his case to a grand jury by the end of the year.

CNN reached out to Mitchell for comment on the case.

CNN's KSAT reported Wednesday that it did not respond to a request for comment.

In June 2022, Mitchell told CNN that he did not want the recordings or videos released while investigations were ongoing. \Any release of records relating to this incident at this time would interfere with the ongoing investigation and hinder a thorough and thorough investigation,\ he said.

A total of 376 law enforcement officers from multiple agencies responded to the May 2022 shooting, but waited 77 minutes before the 18-year-old Uvalde resident, who was held in two adjacent classrooms with the victims, walked in and killed the gunman.

During this time, terrified students sought help from the 911 operator, as police remained in the hallway.

Following the incident, residents, state leaders and lawmakers criticized the police response and lack of transparency regarding internal investigations.

This week's lawsuit marks the second time McLaughlin has filed a lawsuit with the district attorney, accusing him of refusing to share evidence with the city's independent investigator, Jesse Prado.

McLaughlin said the first case was filed in December and Mitchell was voluntarily dropped after promising to cooperate with Prado's requests for evidence. \The City has had to sue a second time because D.A. Christina Mitchell continues to obstruct the City's investigation,\ the mayor's statement said.

The U.S. Department of Justice is also reviewing law enforcement response to the deadly attack.
