Colleen Renee Brockman was 15 when she disappeared from Seattle, Washington. The family last saw her on December 23, 1982; she was reported missing around Christmas Eve. Described as trusting and known to spend time on the streets, she had taken some belongings from the family home before she vanished, and her father reported those items stolen in an effort to locate her.

Her remains were found on May 26, 1984, in Pierce County near Sumner and were identified in part because she still had braces on her teeth. Her death became one of multiple disappearances and recoveries of remains in the Seattle–Tacoma area during the early 1980s associated with the Green River investigations. A later investigation linked Gary Leon Ridgway to many of those killings; Ridgway confessed to killing Colleen around December 24, 1982, saying he killed her in the back of his truck.

Does anyone have memories of Colleen from Seattle in 1982 or information about her movements in December that year?
