Gunman kills one, injures three on Seattle campus06 june 2014, 11:49
A lone gunman killed one person and injured three others Thursday on a college campus in the northwestern US city of Seattle, where the mayor denounced America's "epidemic of gun violence", AFP reports.
The latest bloody rampage to shake the United States came just two weeks after an apparently mentally disturbed man opened fire at a California university and killed six people.
Those wounded at Seattle Pacific University, including at least one who was critically hurt, were being treated in hospital. The dead victim was a 20-year-old man, according to police.
The Seattle Police Department described how the gunman opened fire in a lobby of a science building on the campus.
"Police have one suspect in custody, an adult male who was subdued after being pepper-sprayed by a student security guard," the police statement added.
Initial reports suggested there were two gunman, but police said that proved false.
Mayor Ed Murray expressed outrage that his city had fallen victim once more to the gun violence plaguing the United States.
"Today should have been a day of celebration at the end of the school year. Instead it's a day of tragedy and of loss," he told reporters.
"Once again, the epidemic of gun violence has come to Seattle, the epidemic of gun violence that's haunting this nation."
'Piles of blood'
Witnesses described their fear as the shooting unfolded, and the bloody aftermath. One student recounted hearing a loud bang from next to the classroom he was in.
His teacher initially thought it was a science experiment, but someone went out and came back saying: "I think someone's been shot."
"So we turn off the lights we lock the door and we close the blinds," the student, identified as Blake, told KIRO 7 TV.
"I was scared for about a minute," he added, recalling hearing shouting and someone running past the door.
After a couple of minutes, "cops come in through another classroom which was connected to ours and they escorted us out.
"I just saw piles of blood on the ground, just scattered throughout the lobby. And I actually stepped in a puddle....
"I saw someone was on the ground. Someone was on top of them, their hands behind their head."
Police spokesman Chris Fowler described how the young male gunman was taken into custody after opening fire in the lobby of a building on the campus.
He began to reload when a student who was monitoring the building "confronted the shooter (and) was able to subdue the individual," Fowler told reporters, without directly confirming the death.
"Once on the ground, other students jumped on top of them and they were able to pin the shooter to the ground until police arrived."
Less than two weeks ago, a reportedly mentally unstable 22-year-old man killed six people before turning the gun on himself at a college campus in Santa Barbara, California.
School shootings have become a tragic periodic occurrence in the United States in recent years.
They include the December 2012 massacre in Newtown, Connecticut that left 20 small children dead, and the Virginia Tech shooting in April 2007 in which 33 died, including the gunman.
