Khoi Dang Vu was 25 when he disappeared from his family home in Vancouver, Washington, in the early hours of April 7, 2007. Family members last saw him between midnight and 1 a.m.; by 8 a.m. his bed appeared unslept in and he was gone. Khoi was deaf, nonverbal, and had developmental disabilities described as giving him the cognitive level of a ten-year-old. He communicated with writing, gestures, and limited ASL and was known for approaching strangers to introduce himself.

Khoi left without his favorite jacket and without his bicycle, and a heavy rain had passed through that night. Initial searches involved local law enforcement and, within a couple of days, the FBI. Investigators checked registered sex offenders and store security footage and followed a reported sighting at an elementary school that was later ruled to be someone else. A reward was offered and the case was ultimately reclassified from missing person to a criminal investigation; authorities now suspect Khoi was killed and that his body was placed in a dumpster later taken to a landfill near Boardman, Oregon. His remains have never been recovered and no suspects have been publicly named.

Does anyone have information about Khoi’s last known movements or contacts on April 6–7, 2007?
