UVALDE, Texas (AP) — State police say the Robb Elementary School teacher who propped open an exterior door that a gunman used to get inside and kill 19 students and two teachers had closed the door, but it did not lock.

Investigators initially said the teacher propped the door open with a rock and did not remove it before 18-year-old Salvador Ramos entered the building on May 24.

Travis Considine, a spokesman for the Texas Department of Public Safety, said Tuesday that investigators had determined the teacher removed the rock and closed the door when she realized there was a shooter on campus but that it did not lock.

The teacher has not been identified.

According to Considine, the teacher initially propped open the door but ran back inside to grab her phone to call 911 when Ramos crashed his truck.

Considine added that the teacher then came back outside, and while on the phone, she heard someone yell that he had a gun.

She then watched Ramos jump the fence and saw that he had a gun. She then removed the rock and ran back inside, Considine said.

Considine said they did verify that the teacher closed the door and that it did not lock.

He added that investigators are looking into why the door did not lock.

UVALDE, Texas — The lawyer for the principal of an elementary school in Texas where 21 people were killed in a mass shooting says she has returned to her job after being placed on administrative leave earlier this week.

On Monday, Robb Elementary School principal Mandy Gutierrez's attorney told CNN that his client was on paid leave.

On Thursday, her attorney told ABC News, CNN, and Reuters that she was reinstated.

A reason for her being placed on paid leave was not given, the news outlets reported.

CNN reported that her reinstatement comes a day after she defended herself against a Texas House committee investigation report of the deadly school shooting.

In the report, the news outlets reported that Gutierrez was criticized for failing to fix a lock on the school door the gunman used to enter the school on May 24.

On Wednesday, she called the accusations "unfair and inaccurate," the Texas Tribune reported.

Gutierrez became principal of the elementary school last year.
