A gunman shot and killed a student at an Oregon high school Tuesday and was later found dead in a bathroom stall.

Authorities have identified the victim as 14-year-old high school freshman Emilio Hoffman.

This is the third violent outbreak in a high school or college campus in less than three weeks and brings the total number of school shootings to 74 since the Sandy Hook shooting in December 2012.

This means, on average, a school shooting occurs every 7.33 days since the tragedy in Newtown — a statistic that troubles President Barack Obama.

“We’re the only developed country on Earth where this happens,” Obama said Tuesday during a question-and-answer session on Tumblr. “And it happens now once a week. And it’s a one-day story. There’s no place else like this.”

Reynolds High School — in Troutdale, a suburb of Portland — was immediately locked down and evacuated room by room following the shooting.

“A gunman entered the high school this morning, shot one student. Unfortunately, that student has died,” Troutdale Police Chief Scott Anderson said at a news conference. “The gunman was located and the gunman is also deceased.”

Todd Rispler, a Reynolds HS gym teacher and track coach, was grazed by a bullet but was able to make his way to the school’s office to initiate the lockdown, Anderson said.

Although no official statement has been made concerning the shooter, USA Today cited a police spokesman as saying the shooter was a teenager who shot himself to death in a bathroom stall following the attack.

President Barack Obama spoke of his fear and frustration Tuesday at the lack of gun control and rash of violence in schools.

“The country has to do some soul searching about this. This is becoming the norm and we take it for granted in ways that, as a parent, are terrifying to me,” Obama said.

“Today, Oregon hurts as we try to make sense of a senseless act of violence,” said Oregon Governor John Kitzhaber.
