The school district police chief who served as on-site commander during last week's deadly shooting in Uvalde said Wednesday that he's talking daily with investigators, contradicting claims from state law enforcement that he's stopped cooperating.In a brief interview, Uvalde Consolidated Independent School District Police Chief Pete Arredondo told CNN that he's speaking regularly with Texas Department of Public Safety investigators."I바카라 게임 웹사이트�ve been on the phone with them every day,바카라 게임 웹사이트� Arredondo said.Nineteen children and two teachers died in the attack at Robb Elementary School, the deadliest school shooting in nearly a decade. State officials have said 19 police officers waited outside the classroom where Salvador Ramos, 18, had opened fire, despite repeated pleas from children calling 911 for help.Travis Considine, chief communications officer for the Texas Department of Public Safety, said Tuesday that Arredondo had not responded to DPS requests for two days, while other officers in the Uvalde city and schools police departments continue to sit for interviews and provide statements.Arredondo has not responded to multiple requests for comment from The Associated Press.The confusing and sometimes contradictory responses in the week since the deadly shooting continued Tuesday with the revelation that the exterior door used by the gunman was not left propped open by a teacher, as police previously said.They have now determined that the teacher, who has not been identified, propped the door open with a rock, but then removed the rock and closed the door when she realized there was a shooter on campus, Considine said. But, Considine said, the door that was designed to lock when shut did not lock.바카라 게임 웹사이트�We did verify she closed the door. The door did not lock. We know that much and now investigators are looking into why it did not lock,바카라 게임 웹사이트� Considine said.Investigators confirmed the detail through additional video footage reviewed since Friday's news conference when authorities first said that the door had been left propped open. Authorities did not state at that time what had been used to prop open the door.Video: Funerals begin for Uvalde victimsConsidine said the teacher initially propped the door open but ran back inside to get her phone and call 911 when Ramos crashed his truck on campus."She came back out while on her phone, she heard someone yell, 'He has a gun!', she saw him jump the fence and that he had a gun, so she ran back inside," removing the rock when she did, Considine said.Steve McCraw, the head of DPS, hadn바카라 게임 웹사이트�t said why the teacher initially propped open the door when it was first detailed Friday. The first mention of a door left propped open, which officials now say didn't happen, led to questions about the teacher's actions and whether she had made a horrific mistake.Since the shooting, law enforcement and state officials have struggled to present an accurate timeline and details of the event and how police responded, sometimes providing conflicting information or withdrawing some statements hours later. State police have said some accounts were preliminary and may change as more witnesses are interviewed.San Antonio attorney Don Flanary told the San Antonio Express-온라인 바카라 게임 that the Robb Elementary School employee, whom he바카라 게임 웹사이트�s not naming, first propped open the door to carry food from a car to a classroom, and that she immediately moved to close it when she realized the danger."She kicked the rock away when she went back in. She remembers pulling the door closed while telling 911 that he was shooting," Flanary told the newspaper."She thought the door would lock because that door is always supposed to be locked,바카라 게임 웹사이트� Flanary said.Video: Flowers, tears as Bidens stop at Uvalde memorialFlanary did not immediately return telephone messages left at his office from The Associated Press.Later Tuesday, the Combined Law Enforcement Association of Texas, which represents police officers, urged its member officers to cooperate with "all government investigations" into the shooting and police response and endorsed a federal probe already announced by the Justice Department.The organization was also sharply critical of the constantly changing narrative of events that has emerged so far."There has been a great deal of false and misleading information in the aftermath of this tragedy. Some of the information came from the very highest levels of government and law enforcement," CLEAT said. "Sources that Texans once saw as iron-clad and completely reliable have now been proven false."
