An 11-year-old girl is accused of stabbing a classmate at a San Antonio middle school. On Thursday, a judge said she will stay locked up for now.

It happened Wednesday, Sept. 30, at Metzger Middle School. The school is part of Judson ISD. It happened during a planned lockdown drill.

The girl went to court Thursday morning. Her dad and her grandma were with her. Judge William "Cruz" Shaw heard the case.

El Tejano is not naming the girl or the other student. Both are children.

"I want my baby home. She's my only child," the girl's father told the court.

The judge said no. She will stay in detention until at least her next hearing. That hearing is set for Oct. 15.

Prosecutors asked the judge to keep her. They said she was not "allowing herself to be adequately supervised." They said she could be a danger to herself or others.

Prosecutors also told the court two more things. First, a campus police officer had to draw his gun on the girl that day. Second, a student had reported her the week before for having a knife. Prosecutors said school staff checked but did not find one.

A juvenile probation officer spoke too. The officer said the girl's dad reported no behavior problems at home. The dad believed the stabbing was not like his daughter.

The judge also spoke right to the girl.

"You made a really bad choice, OK?" Shaw told her. "And there's consequences to those choices. You understand that?"

Here is what the school district has said.

The school was already in a planned lockdown drill when the fight broke out, Interim Superintendent Ann Dixon said. Staff kept students on hold after the drill ended. Dixon said two students were involved. She said both were taken to a hospital.

"During the response, a weapon was located and immediately confiscated," said Lexie Greathouse, who speaks for Judson ISD. "The situation was quickly contained."

The district said the case was sent to police. Judson ISD police are looking into it.

"The parents of the students involved were informed immediately," Dixon said.

The district has not said how badly the other student was hurt. Officials said federal student privacy laws keep them from sharing more.

School board trustee Jose Macias has said he was told a girl stabbed a boy. He also said he was told the girl had more than one knife in her backpack. Police and the district have not confirmed the backpack claim.

In a letter to families, the district asked parents to talk with their kids. It wants students to tell a trusted adult when they see something that worries them.

That message hits hard after what prosecutors said in court. A student spoke up the week before, prosecutors said. Staff looked and found nothing.

Under Texas law, most cases against kids ages 10 to 16 go to juvenile court. They do not go to adult court.

For now, many questions are still open. How badly was the other student hurt? What exactly did staff check the week before? The district has not answered those questions in public.

The girl goes back before the judge on Oct. 15.

Everyone is presumed innocent until proved otherwise.
