Helen Irene Tucker, 26, disappeared from downtown Tacoma, Washington after being seen on January 20, 1994, in the vicinity of Puyallup Avenue. That evening she contacted police to report an attempted assault; that interaction was her last known contact with anyone. She sometimes used the surname Cook.

At the time she went missing she was described as white, brown hair, blue eyes, about five feet five inches and 115 pounds, with a rose tattoo on her right arm and a gnome tattoo on her left arm. She left behind a young son. The case was not officially reported until April 2000, a delay that investigators say hampered early interviews and follow-up. Her case was later reviewed by the Green River Killer Task Force but Gary Ridgway was excluded and the investigation reverted to Tacoma police. There was a possible, unconfirmed sighting in Aurora, Colorado.

Investigators believe foul play is likely, but what happened after her last contact with police remains unknown. Did anyone living in Tacoma around January 1994 recall seeing Helen near Puyallup Avenue or know someone who might have information about her movements that night?
