When Antoinette Riley was arraigned Friday on charges that she carried a loaded gun into the cafeteria of Jason Lee Elementary School, the mother of a child who goes to the school was watching from the courtroom gallery.

Jenny Stine said she knows Riley looked over and recognized her. Stine wanted Riley to know that what she’s accused of doing is a big deal for the entire school community.

Stine's 10-year-old daughter wasn't one of at least 50 students in the cafeteria when the gun suddenly went off during an after-school program Oct. 4, but she was in the building.

“My rose-colored glasses have been taken off,” Stine said. “This is not some stranger who just came in. It was a parent. It was someone who’s allowed to be in the school. It’s shaken me up.”

It also rattled her daughter, who was “bawling” when Stine arrived to pick her up that afternoon, she said.

“I hugged her,” Stine said.

Her daughter told her that although she was in another room of the school, she later saw the bullet’s damage to the table and bench.

Riley pleaded not guilty to an indictment that accuses her of possession of a firearm in a public building, unlawful possession of a firearm and possession of a loaded firearm in public.

Oregon law allows adults, including parents or teachers, to bring guns into schools -- but not without a concealed weapons permit. Based on the charges against Riley, she apparently didn’t have one.

Riley has declined to comment to The Oregonian/OregonLive on several occasions, including after Friday's arraignment. Her attorney, Jason Steen, didn’t attend the hearing. He couldn’t be reached for comment.

But in a probable cause affidavit, police say Riley was at the school to pick up her children and she had been sitting at the table and bench where the bullet struck. The manager of the after-school program said Riley had the gun in her bag.

The affidavit says Riley immediately left the cafeteria but police who tracked her down found a bullet hole in the fabric of her bag and Riley said she’d been shot in the buttocks.

Police weren’t able to recover the gun.

Riley was booked into Multnomah County jail and released later that night.

On Oct. 5, KPTV reported that Riley told the TV station she didn’t bring a gun to the school and police arrested the wrong person.

“I did not do it. I didn’t do it,” KPTV reported Riley as saying. “Why would I harm a student? Or even harm anybody at all? My kids, they literally go to school there, so I’m just like, this is stupid.”

Court papers state Riley, a mother of five, lives near the school. It's at 2222 N.E. 92nd Ave.

Jason Lee Elementary’s assistant principal, Blake Robertson, sent a letter home the evening of the shooting.

“This is an alarming incident and we are thankful that no one was hurt,” Robertson wrote. “Keeping our students safe is a responsibility we take very seriously. ...We are working to ensure we have counselors and other support staff at school in the morning to provide assistance to students and staff.”

Stine, the mother who showed up at the Multnomah County Circuit Court arraignment, wore a Jason Lee Elementary T-shirt to show her school pride. She said she’s talked to other parents about how they all don’t want this one event to define the school.

“We have such a great community at Jason Lee,” Stine said. “It doesn’t represent our school community.”

Riley's trial date has not yet been set.
