More details have come in regarding the tragedy today at Reynolds High School in Columbia River, Oregon.
As previously reported, authorities were alerted to an active shooter inside the building around 8 a.m. local time, with over 60 emergency personnel vehicles arriving at the scene.
Students were keeping parents aware of activity inside via Tweets and/or text messages, with the premises on lockdown for over an hour until police deemed the situation safe.
We can now confirm, via The Associated Press, a teen gunman armed with a rifle shot and killed one student in the attack, while also wounding a 50-year old teacher named Todd Rispler.
His injuries were not life-threatening.
The identities of both the deceased victim and the shooter are being kept under wraps at the moment, but authorities discovered the latter slumped over by himself inside a bathroom stall.
They used a robot with a camera to investigate and discovered the suspect was dead, most likely of a self-inflicted gunshot, according to Troutdale Police Spokesman Sgt. Carey Kaer.
"Oregon hurts as we try to make sense of a senseless act of violence,” said Governor John Kitzhaber in a statement this afternoon.
Reynolds is the second-largest high school in Oregon, with about 2,800 students. It is located about 15 miles from Portland.
Today's incident comes less than a week after gunman opened fire on a college campus in neighboring Washington, killing a 19-year-old man and wounding two others.
It marks the 74th school shooting since the tragedy of Sandy Hook Elementary School in Newtown, Connecticut in late 2012.
