LOS ANGELES (AP) -- A shooting at a Los Angeles middle school classroom Thursday that left one boy in critical condition, injured four others and had panicked parents in tears was an accident, police said.
The shooting was reported just before 9 a.m. and within minutes a 12-year-old girl was taken into custody without incident. Police interviewed her and by evening they announced that they would book her on a charge of negligent discharge of a firearm on school grounds.
The determination capped a frantic day at Salvador B. Castro Middle School in downtown Los Angeles and corroborated what some students told reporters after the lockdown was lifted and they were reunited with parents on the school's athletic field.
In a telephone interview with his mother alongside, Jordan Valenzuela, 12, told The Associated Press he was in the classroom next door when he heard a loud bang. He said he talked to the girl just after the shooting and she was sobbing.
"She was like, 'I didn't mean to. I had the gun in my backpack and I didn't know it was loaded and my backpack fell and the gun went off,'" he said.
Shortly after that he said the girl asked him to hide the weapon.
"She said, 'If I give you the gun will you hide it for me?'" he said. "I said 'No.' Then I moved away from her because I was a little bit scared."
Shallin Lopez, a seventh-grader at the school, was in the room at the time of the shooting. She said she never saw a gun.
"I just saw something pop," she said. "It was loud. I didn't see her shoot."
Police recovered a semi-automatic handgun after the shooting. TV video from helicopters showed a dark-haired girl in a sweatshirt being led from the school in handcuffs as anxious parents and family members gathered on a street corner, many crying and talking on their phones as they waited.
Diego Salinas had just dropped off his 12-year-old sister and was stunned when she called minutes later to say there had been a shooting.
"There were so many things crossing my mind," said Salinas, who was still shaking hours later. "I wanted to cry. I wanted to scream. I wanted to run. I wanted do so many things."
Claudia Anzueto, Jordan Valenzuela's mother, said the boy was crying when he called her from a borrowed cellphone to tell her he was OK.
"Not safe, very insecure," Anzueto said of the school. "I fear for my son's life. You know what I mean, you really hear about things like this in the news, and just to hear that something like that happened so close to home, it scared the life out of me."
The district has a policy requiring every middle and high school campus to conduct daily random searches by metal-detector wands at different hours of the school day for students in the sixth grade and up.
Student Melanie Valencia, 13, said the school did a random security search Thursday, but that she's never been checked.
The most seriously injured victim, a 15-year-old boy shot in the head, was taken to Los Angeles County-USC Medical Center and remained in intensive care during the afternoon but was doing well.
"This child was extremely lucky," said Dr. Aaron Strumwasser, a trauma surgeon. "The trajectory of the bullet did not hit any vital structures that were an immediate threat to life."
A 15-year-old girl with a gunshot wound to the wrist was hospitalized in fair condition. An 11-year-old boy and a 12-year-old girl were grazed and were treated and released from the hospital. A 30-year-old woman who was treated after the shooting was not hospitalized and the nature of her injury was not immediately known.
The school's campus was placed on lockdown but most classes continued. The school has about 365 students in grades 6-8 and almost all are Hispanic and many are from low-income families.
"We will attend to the needs of these students who witnessed this very carefully, with the understanding this is very traumatic," said Steve Zipperman, chief of the Los Angeles Unified School District police force. "We have our school mental health folks that are here to support the needs of the students."
