The Uvalde Police Department and the Uvalde Independent School District police force are no longer cooperating with the Texas Department of Public Safety's investigation into the massacre at Robb Elementary School and the state’s review of the law enforcement response, multiple law enforcement sources tell ABC News.
A spokesman for Texas DPS, which is running the state’s investigations, declined to comment.
The Uvalde police chief and a spokesperson for the Uvalde Independent School District did not immediately respond to requests for comment from ABC News.
According to sources, the decision to stop cooperating occurred soon after the director of DPS, Col. Steven McCraw, held a news conference Friday during which he said the delayed police entry into the classroom was "the wrong decision" and contrary to protocol.
The attack, one of the worst school shootings in U.S. history, left 19 children and two adults dead.
This is a developing story.
