A person suspected of opening fire at Oregon high school was dead on Tuesday after the school was placed on lockdown and students were evacuated following reports of gunfire, law enforcement officials said.
Gunfire had been reported at Reynolds High School in Troutdale, north of Portland, a police official for the city said. "All I know is there is a shooting at the high school," the official said.
The Multnomah County Sheriff's Department said in a Twitter message that the shooter was dead and that the situation had been stabilized, but it gave no further details.
CNN had earlier reported that some injuries had been sustained in the shooting, but neither of two local fire departments that responded to the scene, nor a private ambulance service, American Medical Response, have transported any patients from the school, officials from those agencies said.
The police official said that 30 to 40 Troutdale officers were on the scene. Multnomah County Sheriff's deputies also responded, police said.
Television footage showed police officers in helmets and tactical gear, leaving armored vehicles and running near the school's perimeter with long rifles. Students were seen streaming out of the school with their hands raised. The violence in Oregon was the latest in a string of U.S. shootings in recent weeks, including one at a Christian college in neighboring Washington state last week, that have renewed a protracted debate over gun regulations.
