Khoi Vu, 25, was last seen by family members at their home in the 13110 block of NE 92nd Street in the Orchards area. The family planned to leave for Seattle at 8 a.m. the next morning, but Vu was not in the house when they woke. 

Investigators believe Vu was the victim of a homicide, although his body has never been found. Detectives think his remains were likely disposed of in a dumpster and are now interred at a landfill near Boardman, Oregon. The case remains unsolved.
