An Arizona high school senior brought a gun to school and killed himself on Tuesday, television station KPHO reported.
At around 9 a.m., officials at Corona del Sol High School in Tempe notified a security officer that a student on campus was seen holding a weapon out in the open, KPHO reported.
The school was reportedly placed on lockdown while officials called the police.
The security officer attempted to convince Marcus Wheeler, 18, to put down the gun, but the student shot himself in the head, according to the station.
Wheeler reportedly died of his injuries, despite attempts to save him by the Tempe Fire Medical Rescue Department, KPHO reported. No one else was injured.
The station reported that only minutes earlier, at 8:40 a.m. local time, Wheeler tweeted, “there is going to be a suicide in the school right now.”
