Katya Marie Lyne was 15 when she left her Federal Way, Washington, home about 9:00 p.m. on March 21, 1997, after an argument with her father about grades and changing schools. She was wearing a white t-shirt, a black and white flannel pullover, blue jeans, and black boots. Katya left behind personal items including her Social Security card, dental retainer, and shoe lifts.

Her father, Pat Lyne, reported her missing on March 23. He died by suicide on March 25; investigators have said Katya may have returned, found the scene, and fled, though there is no evidence supporting that. Friends and family distributed thousands of flyers and there have been unconfirmed sightings in Puyallup, Seattle, and Midway, but nothing has led to her. Her mother was battling breast cancer at the time, and authorities have said there is no evidence Katya was involved in gangs or abused by her parents.

The case remains open and Katya’s whereabouts are unknown. If anyone knew Katya, saw her in late March 1997, or has information that could help, please come forward.
