- A school resource officer drove past the Texas gunman and accidentally confronted a teacher instead.
- Authorities said the officer heard a teacher phone 911 and showed up at the scene.
- The officer drove right past the gunman, however, who began shooting at the school around 11:30 a.m.
Texas law enforcement officers said a school resource officer drove past the 18-year-old gunman outside Robb Elementary School and accidentally confronted a teacher instead.
After a teacher called police to report that the gunman had crashed his vehicle in a ditch at 11:30 a.m. on Tuesday, the gunman then began shooting at the school, Director of Texas Department of Public Safety Steven McCraw told reporters on Friday
The school resource officer — who was not at Robb Elementary at the time — heard the 911 call and drove to the back of the school. The officer sped over to who he thought was the gunman, but it turned out to be a teacher, McGraw said.
The officer actually drove right past the gunman — who was hiding behind a vehicle and then started shooting at the school before entering the building through an open door, McGraw said.
Once inside, he barricaded himself in a classroom. Nineteen children and two adults were killed in the attack.
Authorities previously said that the officer confronted the gunman, but a top Texas law enforcement official said on Thursday that this did not happen.
"It was reported that a school district police officer confronted the suspect," Victor Escalon, the South Texas regional director for the state Department of Public Safety, said at a press conference.
"That's not accurate," he said, adding that the gunman "walked in unobstructed initially."
The latest description of the school officer's actions are the third different story police have told about what happened in the moments before the gunman stormed the school.
