The situation has been "contained," according to authorities who spoke during a press conference. Police are searching the evacuated students and inside each room of the building to ensure the scene is fully under control. Police couldn't confirm or deny reports of other victims, but nearby hospitals haven't received injured students or staff members, according to NBC News's correspondent Pete Williams. Police also cannot yet confirm details about the gunman or the weapon used in the incident.
The details are still coming in, and it's not uncommon for some preliminary information to be mistaken, but the latest information available to msnbc and NBC News is that at least one student was shot and killed at Reynolds High School in Troutdale, Oregon, this morning. The alleged gunman is also dead and others were injured.
This is the 74th school shooting in the United States since the massacre at Sandy Hook Elementary in Newtown, Conn.
In fact, it's worth noting that BuzzFeed had a pre-scheduled tweet this morning about a company designing bullet-proof blankets, intended to protect children from school shootings, which went live on Twitter during the latest school shooting.
Today's shooting in Troutdale, about a half-hour east of Portland, comes just two days after the mass shooting in Las Vegas.
Which came just two days after the shooting at the courthouse in Forsyth County, Georgia.
Which came just four days after the shooting on the campus of Seattle Pacific University.
Which came just a week after the mass shooting near UC Santa Barbara.
