Detectives seek help with woman's whereabouts before body found near Maple Valley

King County Sheriff’s Major Crimes detectives are asking for the public’s help to determine where a woman went the weekend before her body was found along the shoulder of Highway 18 near Maple Valley on Monday, December 14th.

Investigators say 29-year-old Serena Turner’s cause of death is considered suspicious and is still being determined by the King County Medical Examiner’s Office.  

"We need to fill in the last chapter of Ms. Turner’s life. She was a vibrant young woman and we desperately want to know what happened in those days," said King County Sheriff’s Sgt. Tim Meyer.

Turner, or ‘Ree Ree’ as her family called her, left her home in Lakewood on foot just before midnight on Friday, December 11th.   She was wearing a distinctive purple coat, grey sweatpants and flip flops. Detectives believe she could have traveled to King or Snohomish County.

"We want to find any person, friends, associates, anyone who may have seen her between leaving her home Friday night and when she was found Monday morning," said Meyer.  

Also, detectives are also asking for drivers to check to see if they have any dashcam video driving Westbound on Highway 18 from SE 231st St to Auburn Way between 9:30 and 10 a.m. on December 14th.  If so, please call (206) 296-3311 or send an email at Please reference case C20039619.
