The Case of Shawnda Leea Summers
Shawnda Leea Summers was 17 when she disappeared from Seattle on October 9, 1982. Her remains were discovered in August 1983 near the northern boundary of Sea-Tac Airport, almost ten months after she vanished. The recovery added another victim to the growing Green River investigation, and Gary Ridgway later admitted that he had strangled Summers.

Overview / Background
Shawnda Summers was 17 years old and was living in the Seattle area when she disappeared in October 1982. She was last seen on October 9, 1982, in the Seattle area. Her disappearance occurred only one day after Denise Bush disappeared from Pacific Highway South, during a period when Ridgway was killing young women with increasing frequency. By October 1982, the Green River investigation had already expanded considerably. Investigators were searching for a killer believed to be targeting vulnerable young women around Seattle and southern King County.
Crime Scene
Shawnda's remains were discovered on August 11, 1983, near the northern boundary of Sea-Tac Airport, approximately ten months after her disappearance. Ridgway later told investigators that he had strangled Shawnda and left her body near the northern boundary of the airport. The location was consistent with Ridgway's practice of using secluded areas around southern King County and the Sea-Tac area to conceal or dispose of victims.
Investigation
Shawnda's disappearance became part of the Green River investigation, which by this stage involved numerous missing women and recovered bodies. Investigators had difficulty identifying the killer despite extensive efforts. Gary Ridgway had already come to the attention of detectives, but there was insufficient evidence to charge him. Ridgway remained a suspect for years. Investigators eventually obtained biological samples from him in 1987, but DNA technology at the time could not establish the connection needed for prosecution. The breakthrough came in 2001 when advances in DNA testing linked Ridgway to evidence from several Green River victims. He was arrested on November 30, 2001. During subsequent interviews, Ridgway admitted murdering Shawnda Summers. His confession formed part of the evidence used in the eventual prosecution of the Green River killings.
Outcome
Gary Ridgway pleaded guilty in 2003 to 48 aggravated first-degree murders, including Shawnda Summers. He received 48 consecutive life sentences without the possibility of parole under the plea agreement. Ridgway later pleaded guilty to the murder of Rebecca Marrero, bringing his known conviction total to 49.
Notes
Shawnda's murder occurred only one day after Denise Bush disappeared, illustrating the rapid succession of killings during the autumn of 1982. Her remains were not recovered until August 1983, demonstrating the considerable delay between many of Ridgway's victims disappearing and their eventual discovery.
