UPDATED: 7:13 a.m. EDT, Sept. 25 — Law enforcement officials in Washington State apprehended and arrested a suspect in Friday night's shooting at a mall that killed five people before he fled, sparking a nearly 24-hour manhunt in and around the city of Burlington. Arcan Cetin was taken into custody Saturday for allegedly opening fire in the Cascade Mall and killing three women, a man and a teenage girl, the Seattle Times reported.
Cetin was arrested in Oak Harbor, about 28 miles away from the shootings, after police were able to connect a car in the mall's parking lot to him. He was not immediately charged with a crime but was still expected to make his first court appearance at some point Monday.
He reportedly has a criminal history, though it was not immediately clear what his offenses were.
UPDATED: 6:40 a.m. EDT, Sept. 24 — Officials from the Washington State Patrol announced early Saturday that the fifth person, a male victim, involved in the Cascade Mall shooting has died. A manhunt for the suspect, who is believed to have acted alone, is still underway.
UPDATED: 2:33 a.m. EDT, Sept. 24 — Law enforcement is revising the death toll once again, this time to four women. Police confirmed earlier that three women were shot dead in a northwestern Washington state mall and one other victim was left in critical condition.
It was not immediately clear if the fourth person to be declared dead was the person who was critically injured or if it was a separate victim who was not initially accounted for. A different shooting victim was hospitalized with non life-threatening injuries.
UPDATED: 2:28 a.m. EDT, Sept. 24 — Witnesses to Friday night's deadly mall shooting in northwestern Washington state have come forward with their accounts that underscore the panic many likely experienced during the throes of the gunfire, the Associated Press reported.
After detailing "what sounded like four balloons popping," Tari Caswell said went on to describe her harrowing experience at the Cascade Mall in Burlington. "Then I heard seven or eight more, and I just stayed quiet in the dressing room because it just didn't feel right. And it got very quiet. And then I heard a lady yelling for help, and a man came and got me and another lady, and we ran out of the store."
The suspect has been described as a Hispanic male. Burlington, a town of more than 8,300 people, has nearly 32 percent Hispanic population, according to the most recent Census Bureau data available. The gunman fled shortly after the shooting and law enforcement was not able to immediately apprehend him.
UPDATED: 1:54 a.m. EDT, Sept. 24 — There are unconfirmed reports that the suspected gunman may have had an accomplice in Friday's night's deadly shooting at the Cascade Mall in northwest Washington state. An unverified Twitter user tweeted that an older white man was seen with the person authorities have identified as the shooting suspect before the deadly rampage took place.
However, the Skagit County Department of Emergency Management announced law enforcement was looking for a "single suspect," making it uncertain which report was accurate. At least three people died Friday from gunshot wounds and two others were hospitalized with injuries, including one person who was listed in critical condition.
An unidentified witness said the shooter was yelling a woman's name while he was shooting in the Macy's department store at Cascade Mall in Burlington, Washington, according to an unconfirmed report on Facebook. Three women were reported as the fatal victims in the shooting, which took place about 65 miles north of Seattle.
The FBI's office in Seattle announced it was aiding local law enforcement with its investigation as police continued to search for the man who was seen on the mall surveillance camera footage carrying what appeared to be a rifle.
The suspect was last seen walking toward Interstate 5, a nearby highway, shortly after the shooting. A motive for the shooting was not immediately clear.
UPDATED: 1:26 a.m. EDT, Sept. 24 — All three people who were killed Friday night in a shooting at a mall in northwest Washington state were women, according to a report from the Seattle Times. Five people were shot in total, including two survivors, one of whom was injured critically. The other survivor sustained non life-threatening injuries.
Reports surfaced immediately following the shooting at Cascade Mall in Burlington that four people were dead, but the Washington State Patrol eventually revised the death toll numbers.
The shooting took place shortly after 9 p.m. local time in the Cascade Mall's Macy's department store. The entire shopping center was evacuated as emergency responders arrived to the scene. The suspect is reported to have fled on foot toward Interstate 5, a nearby highway.
Photos of the suspect, who authorities have described as being a Hispanic male with a slight build, were captured from mall security surveillance footage and quickly disseminated on social media. The suspect had not immediately been located and a search for a lone gunman was underway.
UPDATED: 1:10 a.m. EDT, Sept. 24 — While the only description of the suspect in a deadly shooting at a mall in northwest Washington is of a Hispanic male, users on Twitter seemed to doubt the partial identification and speculated if the violence was instead the work of Islamic terrorism by a Muslim.
Because the Cascade Mall shooting suspect was still at large, a nearby high school football game in Burlington was halted out of caution.

UPDATED: 12:24 a.m. EDT, Sept. 24 — Photos of the suspected shooter in a deadly shooting Friday night at a mall in Washington state have emerged.

There was no immediate indication that Friday night's shooting was an act of terror, although police were investigating that possibility.
All four people killed were found in a Macy's department store, according to local news outlet Q13 Fox. The retail chain's store in the Cascade Mall in the town of Burlington is reportedly where the gunfire started.
