Witness recounts police response to Uvalde shooting: 'Why aren't they going in?'
Bob Estrada, who lives across the street from Robb Elementary School, recounted to ABC News the moments he went out on his porch after hearing gunshots, saying he witnessed the police response to the shooting unfold.
Estrada, whose grandson is a second grader at the school who survived the shooting, said he saw "quite a few" officers outside the school immediately, and then police cars started driving up -- but "some of them just stood there."
"Why aren't they going in?" Estrada told ABC News he wondered at the time.
Estrada said it was not long before parents began to arrive. "They were hysterical," he said.
"There were parents out there, and they were kinda motioning like they wanted to come in," Estrada said. "They were motioning like, 'What are you doing? Go in!'"
Estrada said he did see some officers go in immediately.
Asked if he saw reinforcements heading into the school, Estrada said no. But, he did not know what sort of presence may have already been inside.
