Mourners in Washington 'Shine Light Into the Darkness' after Mall Shooting

Residents of Burlington, Washington, held a candlelight vigil Monday night for victims of the mall shooting there.

Hundreds of mourners gathered, singing "Amazing Grace" and lighting candles to remember the five lives taken by the shooter.

"Tonight we have an opportunity to physically and spiritually shine light into the darkness," one minister told the crowd.

"I lost a dear friend and that's why we're here," Rick Block said. "Knowing that my buddy lost his girlfriend in it, it just touched me hard, it really hit me hard."

The suspect, Arcan Cetin, has admitted to the shooting, but his motive is unclear. His family says he struggles with mental illness.

Monday was Cetin's first day in court. He is being charged with five counts of first-degree premeditated murder and could face life in prison if convicted.

Just before the shooting on Friday, Cetin shared an early dinner with his stepfather, then told him he was headed to his job at a gym.

Instead, police say he headed to the Cascade Mall in Burlington, pulled a Ruger rifle from his trunk and opened fire in a Macy's department store, instantly killing three women and a teenage girl and critically wounding a man who died hours later.

The victims ranged in age from a 16-year-old girl to a woman in her 90s and included a probation officer and a Boeing maintenance worker.

Cetin, 20, of Oak Harbor, has a criminal record dating back at least two years and was charged last year with assaulting his stepfather.

Court records show he had been diagnosed with anxiety and depression and has taken unspecified medications in the past.

He immigrated from Turkey and is a permanent legal resident, authorities said.
