PORTLAND, Ore. (KOIN) – The man accused of shooting and killing a woman on the Eastbank Esplanade Sunday night has made his first court appearance.

On Tuesday, the defense attorney representing 25-year-old Wyatt Storm Belcher put in his plea of not guilty.

Just before 11:45 p.m. Sunday, police say a woman was shot and killed on the esplanade near SE Salmon Street.

Court documents identified the victim as a woman named Ash Marie Smith — but said they don’t believe she and Belcher knew each other.

Documents say the medical examiner determined Smith’s death a homicide and that she died of a single gunshot wound to the back of the neck.

Belcher was booked into the Multnomah County Detention Center and faces charges including second-degree murder and unlawful use of a weapon.

Portland State University told KOIN 6 News he was an engineering student at their school but is not currently a student.
