News 6 reporters saw parents rushing to pick up their kids from Lake Mary High School throughout the day Wednesday after school leaders notified parents about the incident.

"I was working when he texted me, and then I just started asking him what’s going on," parent Hilsia Fernandez said.

The school was placed on lockdown after hearing the gunfire in case of the possibilty of there being an active threat on campus.

"When it happened, I actually ran into another classroom," student Angel Diaz said. "They say that we’re still going to be on code red, and they explained about the girl that shot herself."

Many students were in shock after officials told them what happened.

Some parents said the tragedy is unfortunate and serves as a reminder to talk to their kids.

"I was just telling my son, whatever problem you have, come to me, talk to me and we can figure out if we can resolve the problem," Fernandez said.

The student's name has not been released and authorities are still working to figure out how she was able to get a gun, according to the Seminole County Sheriff's Office.
