A lone gunman armed with an assault rifle invaded an Oregon high school Tuesday and opened fire, killing at least one student.

The gunman was also later killed, police said, although it was not clear if he was felled by police bullets or by his own hand.

What was clear is that once again an American school where kids are supposed to be safe was transformed by a gun-toting maniac into a crime scene.

It was the 74th shooting at a school since the December 2012 massacre at Sandy Hook Elementary School in Newtown, Conn. - and the 37th just this year, according to a tally by Moms Demand Action for Gun Sense in America.

"This is a very tragic day, one that I hoped wouldn't be part of my experience," schools superintendent Linda Florence said. "We feel very sorry for our parents."

Reynolds High School in suburban Portland remained on lockdown as SWAT teams combed through the classrooms to make sure everyone is accounted for.

The shooter, who was reportedly clad in black and wearing a helmet of some kind when he barged into the school, was found dead in a bathroom, officials said.

Students reported the killer was trying to plant a bomb of some kind.

While the Multnomah County Sheriff's Department did not confirm those reports, in a Twitter message they said the shooter was dead and that the situation at the school in Troutland, Ore., had been "stabilized."

"We are still checking the building," Sue Strickland of the Troutland Police told USA TODAY. "We have about 40 to 50 units out there. We have several SWAT teams in the building right now and they are checking to make sure that they've got things under control. A semiautomatic weapon was used."

Freshman Daniel DeLong, 15, said he saw a gym teacher at the school with a bloodied shirt. He was believed to be Todd Rispler, who was wounded in the hip.

"I'm a little shaken up," DeLong told the Associated Press. "I'm just worried."

DeLong said he was texting friends to make sure they were all safe.

"It just, like, happened so fast, you know?" he said.

Freshman Morgan Rose, 15, said she was hunkered down in a locker room with another student and two teachers.

"It was scary in the moment now knowing everything's okay," she said.

Initial reports were that the gunman was armed with an AR-15 rifle, the same kind of weapon Adam Lanza used to slaughter 20 students at six staffers at the Sandy Hook school.

It was 8 a.m. on the next-to-last day of classes when the shooting started.

Immediately, teachers began herding their 2,800 students into classrooms and locking the doors.

When they were given the sign, the teachers began evacuating their charges from the school.

"Get out! Get out!" the more panicked teachers cried out.

Soon students were seen marching out of the building with their hands over their heads - and with terrified

looks on their faces - towards heavily armed state police and FBI agents.

Waiting further on were hundreds of worried parents - some of them still in their pajamas - frantically looking for their kids.

Mandy Johnson said her daughter called from a friend's phone.

"I thank God that she's safe," said Johnson, who has three younger children. "I don't want to send my kids to school anymore."

The Oregon violence was the latest in a string of school shootings, most recently last week at a Christian college in Seattle that left one dead and two wounded.

But it was the first fatal school shooting in Oregon since May 1998, when 15-year-old Kip Kinkel killed two students and wounded 25 others at his high school near Eugene.

Kinkel also killed his parents and is serving an 111-year prison sentence.
