Human remains discovered in 1988 by a horseback rider in Washington have been identified as Rosa Elia Vargas Jimenez Everts, who had been reported missing by a former roommate almost four decades ago. Rosa was last seen when she was just 31 years old, and her disappearance was officially reported in 1987.

The initial discovery of the remains was made near Parker Bridge Road and the Sunnyside Dam area in Parker. Despite an exhaustive investigation at the time, no significant leads were uncovered. It was not until recently that DNA analysis provided a breakthrough in the case, leading to the identification of Rosa Elia Vargas Jimenez Everts from Toppenish.

The Toppenish Police Department revealed that Rosa’s former roommate reported her missing on August 6, 1987, after realising that she had not returned to California as planned and had lost touch with her family. The roommate initially thought Rosa had gone back to California until informed otherwise by Rosa’s family members.

Although authorities explored the potential connection between Rosa’s disappearance and the unidentified remains found in 1988, known then only as “Parker Doe,” conclusive evidence was lacking, causing the case to go cold. However, a review of the case in August 2024 reignited interest in solving Rosa’s disappearance.
Senior Investigator and Analyst Carlos Trevino from the Washington Attorney General’s Office played a crucial role in tracing Rosa’s family members in Utah, obtaining vital information that propelled the case forward. DNA samples from Rosa’s mother and sister were compared to the remains, resulting in a positive match in October 2025.
With the identification of Rosa Elia Vargas Jimenez Everts, authorities hope to bring closure to her family and friends after almost four decades of uncertainty. Efforts are underway to repatriate her remains to her loved ones, allowing them to finally lay her to rest.
The Yakima County Sheriff’s Office expressed gratitude to everyone involved in the investigation and identification process. They acknowledged the collective effort that led to the resolution of Rosa’s case and offered support to her family during this challenging time.
As the criminal investigation continues, officials urge anyone with information related to the case to contact cold case investigator J. Mark Keller. The closure brought by identifying Rosa Everts serves as a poignant reminder of the importance of ongoing efforts to resolve cold cases and bring justice to families affected by long-standing mysteries.
The identification of Rosa Elia Vargas Jimenez Everts after nearly four decades showcases the perseverance of law enforcement and the significance of advancements in forensic technology.

The case of Rosa Everts serves as a testament to the enduring commitment of investigators to bring answers and resolution to cold cases, offering a glimmer of hope to families awaiting news of their missing loved ones. This development underscores the impact of continued investigations and advancements in forensic techniques in bringing closure to long-standing mysteries.
In the wake of this breakthrough, authorities remain focused on the ongoing criminal investigation while extending their support to Rosa Everts’ family and loved ones.
