Three persons were killed in a shooting at a mall in Washington.
Searching operation by the police for the shooter who opened fire at a Macy's store at the Cascade Mall in Burlington was still on, Sgt. Mark Francis of Washington State Police said.
He added that it was not immediately known if there was more than a gunman involved, but authorities were searching for a man wearing grey and was last seen walking toward Interstate 5 highway -- the main interstate highway on the West Coast of the US -- from the mall.
Authorities released a photo of a man believed to be the gunman.
"Here is the shooter. We believe just one shooter. ... Armed with rifle," Francis tweeted.
"We have very little information right now," Axtman said.
