Authorities say a fifth person has died following a shooting at a shopping mall north of Seattle.
A spokesman for the Skagit County Emergency Operations Center says the unidentified male victim died early Saturday at a Seattle hospital. Four female victims died earlier following the Friday night shooting at the Cascade Mall in Burlington, Washington.
Authorities continue to search for the shooter.
A Washington State Patrol spokesman says police were seeking a Hispanic man wearing black and armed with a "hunting-type" rifle last seen walking toward Interstate 5.
Authorities say the motive was unknown for the shooting about 60 miles north of Seattle.
Gov. Jay Inslee said tragedy had struck the state.
"We urge residents to heed all safety and detour warnings. Stay close to your friends and loved ones as we await more information and, hopefully, news of the suspect's capture," Inslee said in a statement.
The Cascade Mall is an enclosed shopping mall that opened in 1990, according to the mall's website. It features J.C. Penney, TJ Maxx, and Macy's stores, among other stores, restaurants and a movie theater.
