[Updated at 5:55 p.m. ET] Here's more quotes from Kern County Sheriff Don Youngblood, from the news conference earlier this afternoon, about the teacher and the campus supervisor who apparently talked the suspect into dropping his weapon:
‚ÄúWhen (the teacher) started a dialogue, the shotgun, he said, was pointed in several different directions. He is unsure how many rounds were fired ‚Ä¶ . He said as the dialogue started with him and the campus supervisor, who was just outside the room, the student was still armed with the shotgun. They, I think, probably distracted him in a conversation, allowing students to get out of the classroom and ultimately talking the student down.‚ÄĚ
Youngblood added: "To stand there and face someone that has a shotgun – who has already discharged it and shot a student – speaks volumes for these two young men, and what they may have prevented. They could have just as easily tried to get out of the classroom and left students, and they didn't. They knew not to let him leave that classroom with that shotgun, and they took that responsibility on very serious, and we're very proud of the job they did."
The school district's superintendent told reporters that the school's staff had just reviewed lockdown procedures earlier Thursday morning.

After the suspect shot one student and missed another, "the teacher at that point was trying to get the students out of the classroom and engaged the shooter – who had numerous rounds of shotgun shells ‚Ä¶ in his pockets – engaged the suspect in conversation," Kern County Sheriff Don Youngblood said.
‚ÄúA campus supervisor showed up, was outside the classroom, and together they engaged in conversation with this young man, and at one point he put the shotgun down, and police officers were able to take him into custody,‚ÄĚ Youngblood said.
Here's what Taft Police Chief Ed Whiting said about the teacher and the campus supervisor:
"We want to really commend the teacher and a campus supervisor for all they did to bring this to a very quick resolution before anybody else was harmed. ... They did a great job in protecting the kids, and we can't thank them enough for what they did today."
U.S. Rep. Kevin McCarthy, whose district includes Taft, also praised the teacher.
"I first want to commend the teacher. I think he saved many lives today. His actions, his time, his ability of what he did (to) protect the students there," McCarthy said.
McCarthy also praised law enforcement for responding quickly. Youngblood said Taft police officers were at the school within 60 seconds of a 911 call.

[Updated at 3:41 p.m. ET] The 16-year-old suspect – a student who missed the start of his first class Thursday morning – walked into school in the middle of first period, walked into class and shot a 16-year-old fellow student with a 12-gauge shotgun, Kern County Sheriff Don Youngblood told reporters moments ago.
The shooter then said the name of a second student and fired at that second student, but missed, Youngblood said. The teacher in the class tried to usher students out of the class – there were about 28 students there – and engaged the shooter in conversation, according to Youngblood.
