The Oak Harbor man suspected in the shooting deaths of five people at the Cascade Mall appeared again in court last Friday but still hasn’t been charged.

Arcan Cetin, 20, waived his right to a speedy trial. He will continue to be held in Skagit County Jail under a magistrate warrant, which was extended until Jan. 6.

Both the prosecutor and defense attorney explained that extra time is needed to continue the complex investigation and prepare for a possible trial, the Associated Press reported.

Cetin is being held in lieu of $2 million bail on suspicion of five counts of premeditated murder. He allegedly confessed to the crime, but police haven’t said what his motive may have been, according to court documents. Cetin has a history of mental health problems.

Under Washington state law, a person convicted of aggravated first-degree murder may face the death penalty. One aggravating factor is that there was “more than one victim and the murders were part of a common scheme or plan or the result of a single act of the person.”

Skagit County Prosecutor Rick Weyrich hasn’t said whether he will seek the death penalty. Gov. Jay Inslee, however, has placed a moratorium on capital punishment.

Cetin is accused of stealing his stepfather’s .22 rifle and killing five people at the women’s Macy’s store in the mall in Burlington Sept. 23.
