Denise Darcel Bush was 23 when she disappeared from SeaTac, Washington, on October 8, 1982. She was last seen along Pacific Highway South, an area noted at the time for sex work. A month earlier she and two other women had been arrested on allegations of stealing wheelchairs from a hospital; the outcome of those charges is unclear.

No trace of Bush was found immediately after her disappearance. On June 12, 1985, a skull later identified as hers was recovered in a wooded area in Tualatin, Oregon — an atypical location compared with other victims associated with the same perpetrator. Additional remains and teeth recovered on February 10, 1990, in Tukwila, Washington, were subsequently confirmed as belonging to her. The cause of death could not be determined from the recovered remains.

Denise Bush is listed among the victims of Gary Ridgway, the Green River Killer; reports indicate her skull had been moved to Oregon. If anyone knew Denise, saw her in SeaTac in October 1982, or has information about her movements between 1982 and 1990, please come forward.
