A young man said he dropped everything and rushed to Sal Castro Middle School when his little sister called him and said, "Someone just got shot, I need you".
Mr Im declined to say if investigators believed the girl deliberately opened fire at Salvador Castro Middle School, near the city's downtown district, on Thursday. "There's a lot of things I'm sure are going through her mind right now - she's only 12 years old". "They thought it was a fake gun".
A 15-year-old boy was also shot in the head, and doctors said that it doesn't appear to be life-threatening.
"Someone made a decision to bring a gun, I guess someone was accidentally playing around with it", said Benjamin, a 12-year-old 7th-grader, whose guardian asked that his last name not be used. The bullet went through the wrist of the girl and struck the boy in the head, the LAPD said.
"On Thursday evening, the girl was booked into Juvenile Hall on suspicion of negligently discharging a firearm", AP reported.
"As a parent, this is everyone's worst-case nightmare - a worst-case scenario and a nightmare for all of us", Robert Arcos, commanding officer of the Los Angeles Police Department's Operations-Central Bureau, told reporters Thursday.
Just yesterday, another shooting occurred in an American public school; however, this time authorities are concluding that the incident was accidental.
"The school has been declared safe at this point".
The shooting was reported to authorities around 8:55 a.m. Thursday.
Jordan, 15, later told the AP that the girl sat at the desk with her hands covering her face after the incident, and then she asked him to hide the backpack with the gun in it.
Hernandez left work and sped to the school campus.
"I don't know. Mom go home, I will tell you when we are not in lockdown". A month later, a student died from a shooting at Reseda High School.
The district has a policy which states random searches should be carried out daily with a metal detector wand.
The conditions of the victims were not immediately known, said Sgt. Edward Bernal of the Los Angeles Unified School District Police Department.
The enrollment is 92 percent Latino, and most students are from low-income families.
