Andrea Childers was 19 when she was last seen by a male friend on April 16, 1983, in Seattle, Washington. A month earlier she had been arrested on prostitution charges. Her disappearance remained unresolved for years.

In October 1989 skeletal remains were found in a shallow grave south of Seattle-Tacoma International Airport; forensic examination identified those remains as Andrea Childers. Investigators say the site had been used to dump victims of a serial killer who operated in the region in the early 1980s.

Authorities later connected Andrea to Gary Ridgway, the truck painter from Auburn who targeted vulnerable young women in the Pacific Highway South area, strangling some victims and leaving others in wooded locations. Ridgway eventually confessed in 2003 as part of a plea deal. If anyone knew Andrea, her whereabouts in April 1983, or has information about her last movements, please come forward.
