At least eight people were killed in a shooting Friday morning at a high school south of Houston, law enforcement sources confirmed to CBS News. A suspect was in custody, an assistant principal earlier said.
The school district has said on social media that "there have been confirmed injuries" but didn't provide more details.
Tyler, a senior at the school, told KHOU-TV that his friend saw "some kid" with a gun pull a fire alarm in a school hallway and then run outside. When teachers and students were outside, shots were fired.
"As soon as the alarms went off, everybody just started running outside," 10th grader Dakota Shrader told reporters, "and next thing you know everybody looks, and you hear boom, boom, boom, and I just ran as fast as I could to the nearest floor so I could hide, and I called my mom."
Tyler said he ran behind some trees, heard more shots, jumped a fence and ran to a car wash. He said he saw firefighters treat a girl who had a bandage around her knee and may have been shot.
