Washington state mall shooting: Suspect 'admits' gun attack

[Suarez™]

Prosecutors in the US state of Washington say a 20-year-old man in custody has confessed to going on a murderous rampage in a shopping centre, which left five people dead.
Arcan Cetin was arrested in his hometown Oak Harbor on Saturday, nearly 24 hours after the attack in Burlington, 40 minutes' drive away.
He was born in Turkey and is a legal US permanent resident, officials say.
Investigators say they are not ruling out any motives, including terrorism.
Cetin's stepfather says he has a history of mental health issues.
According to the Associated Press, Cetin's postings online included references to a serial killer and Adolf Hitler, as well as pictures of so-called Islamic State's leader, Abu Bakr al-Baghdadi, and the Iranian Supreme Leader Ayatollah Khomenei.
'Confessed'
Five people - a teenage girl, three women and a man - were killed inside Macy's department store at Cascade Mall on Friday.
Court documents filed by prosecutors allege that Cetin confessed to shooting all five victims with a rifle.
Police said in court papers that all five victims were shot within a minute and the rifle was left on a cosmetics counter before the gunman fled.
At a news conference, police said Cetin had been identified as a suspect after a car connected to him was seen on security camera footage at the shopping centre.
