The Uvalde Police Department and the Uvalde Consolidated Independent School District police force have reportedly stopped cooperating with state investigations into the deadly mass shooting at Robb Elementary School and law enforcement's response to the attack.

The decision to stop cooperating with the Texas Department of Public Safety happened after Texas DPS Director Steven McCraw held a news conference on Friday, when he said the delayed police entry into the classroom where the gunman was barricaded was “the wrong decision” and contrary to protocol, sources told ABC News.

Travis Considine, a spokesman for DPS, said the departments "have been cooperating with investigators" but added, "The chief of the CISD did an initial interview but has not responded to a request for a followup interview that was made two days ago."

Peter Arredondo, the chief of police for the Uvalde Consolidated Independent School District, has been identified as the official who coordinated the response to the shooting. Reports of law enforcement being told not to engage during critical minutes of the assault, as well as videos of desperate parents begging police standing outside the school to go and do something, have fueled calls for accountability.

Information presented by Texas officials has changed drastically over the past week as the investigations continue, though it now appears it took up to an hour on Tuesday before federal agents took matters into their own hands and killed the shooter in defiance of orders not to proceed.

Nineteen children and two teachers were killed in the attack, and several more were wounded. The gunman has been identified as an 18-year-old who officials say legally purchased two AR-style rifles and hundreds of rounds of ammunition.

Arredondo was elected to the Uvalde City Council a few weeks ago and was sworn in Tuesday. However, the mayor announced Monday that plans for a ceremony had been canceled in lieu of funerals for the victims. Uvalde Mayor Don McLaughlin also said Arrendondo was "duly elected" to the City Council and there is "nothing in the City Charter, Election Code, or Texas Constitution that prohibits him from taking the oath office. To our knowledge, we are currently not aware of any investigation of Mr. Arrendondo."

A teacher who propped open a door at Robb Elementary School in Uvalde, Texas, quickly shut it after realizing the threat posed by the shooter, according to the educator's lawyer. The new details cast doubt on the account given by Texas Department of Public Safety Director Steve McCraw, who said Friday that the back door was left open when the shooter crashed his vehicle in a nearby ditch, citing "video evidence."

“She kicked the rock away when she went back in," lawyer Don Flanary said, noting it had been propped open originally to carry food from a car, according to the San Antonio Express-News. "She remembers pulling the door closed while telling 911 that he was shooting. She thought the door would lock because that door is always supposed to be locked."

The employee went back into the school to get her phone to call the police about a truck that had crashed near the school, Flanary explained. She had come back outside as she was on the phone with 911 but ran back inside once she saw the shooter jump the fence, Flanary said.

Texas authorities now suspect the door may have closed but did not lock before the shooter entered the school.


Lt. Gov. Dan Patrick, a Republican, said state officials were initially "not told the truth" about the police response, but McLaughlin's statement asserted this was not true. "All statements and comments made to date about the ongoing investigation are being handled by [Texas Department of Public Safety]/Texas Rangers," the mayor said on Monday.

Texas Gov. Greg Abbott, too, said he was "misled" about the police response to the Robb Elementary School shooting and is "livid" about receiving inaccurate information. "My expectation is that the law enforcement leaders that are leading the investigations, which includes the Texas Rangers and the FBI, they get to the bottom of every fact with absolute certainty," he said Friday.

Public records show Arrendondo completed an active shooter training course as recently as December, NBC News reported. Investigations into the shooting and police response are underway. The Justice Department announced a critical incident review on Sunday.

Uvalde, a town of roughly 16,000 people, is situated between San Antonio and Del Rio, just dozens of miles away from the U.S.-Mexico border. State Sen. Roland Gutierrez, a Democrat whose district includes Uvalde, told MSNBC on Monday there was "failure at every level" of the response to the shooting and that to blame one person is "a little bit irresponsible."

The Washington Examiner has contacted UVD and the mayor's office for comment.
