"There was no police. There were three teachers, max," Briann Fink, a 9th-grader, said.
Fink said she noticed an immediate difference Saturday night at Northwest School of the Arts. Unlike other school events, Saturday's dance and charity toy drive had no sign of police, metal detectors or security.
Fink said a fight inside the dance spilled outside.
That's when police said someone pulled a gun, aimed it at a 17-year-old, and attempted to fire. But, they said, it never went off.
Students rushed back inside to find cover in back rooms, knocking Fink over.
"I was literally laying on the ground. I was one of the last people to get in," Fink said.
Fink's mother, Robin, came back to the school on Monday hoping for answers, but was told it was "under investigation" by the school's principal.
Fink said the social had been advertised in the school for at least two weeks. Eyewitness News found that the school posted the event on its own website last Tuesday.
Still, police sources said they were never informed.
"This is a wonderful school," Robin Fink said. "So whatever happened, somebody dropped the ball."
