Strangled and Dumped in a River: A Teen's Killer Found After 36 Years
The mystery surrounding the tragic death of 18-year-old Tracy Whitney has finally been resolved, bringing closure to a family haunted by unanswered questions for 36 years. Whitney's body was discovered on Aug. 28, 1988, in the Puyallup River in Washington state, following a grim sequence of events that began with her disappearance the day before. Advances in DNA testing and persistent detective work ultimately identified her killer, offering a bittersweet resolution to this decades-old case.
A Day That Changed Everything
Tracy Whitney was last seen alive on the night of Aug. 27, 1988, leaving a Burger King in Sumner, Washington, after a heated argument with her ex-boyfriend. Less than 24 hours later, fishermen found her nude body in the Puyallup River. The autopsy revealed she had died of asphyxia from strangulation, with evidence suggesting probable smothering and sexual assault. Whitney also suffered blunt force trauma, adding to the horrific circumstances of her death.
Despite early DNA evidence collected from the crime scene, investigators in 1988 lacked the technological tools to identify a suspect. For Whitney's family, the years that followed were marked by frustration and heartbreak as leads turned cold.
A Breakthrough in Forensic Science
In 2005, investigators submitted the DNA evidence to the FBI's Combined DNA Index System (CODIS), hoping for a match. Unfortunately, this effort yielded no results, leaving the case unsolved. However, the tides turned in 2022 when the Washington State Attorney General's Office awarded a grant for advanced forensic testing. The DNA sample was sent to Parabon® NanoLabs, a cutting-edge genetic genealogy laboratory, where researchers used the sample to construct a family tree.
Within five months, detectives identified John Guillot Jr. as the primary suspect. Guillot had died of cancer in January 2022, just eight months before the breakthrough. Investigators confirmed his identity by comparing the suspect's DNA to that of his deceased son, whose remains were tested through a medical examiner's office.
Lingering Questions and Mixed Emotions
Although detectives found no evidence that Whitney and Guillot knew each other, they concluded that her death was the result of a random abduction, sexual assault, and murder. This resolution brought relief but also deep sorrow to Whitney's family, who had spent decades seeking justice.
Whitney's sister Robin, who was 11 at the time of the murder, reflected on the duality of emotions the revelation brought. As reported by People, she described feeling finally allowed her to grieve as an adult. She also expressed gratitude for the public's support and shared her hope that Guillot's identification might assist in solving other cases. However, Robin lamented that her sister's killer avoided prosecution, noting that he got away with it due to his untimely death.
The Push for Change
Robin's comments echo a broader concern in the field of criminal justice. She hopes that policies restricting the use of a deceased suspect's DNA in law enforcement databases will be revisited. Such changes could help solve other cold cases and bring justice to additional families who continue to wait for answers.
A Legacy Remembered
Tracy Whitney's life was tragically cut short, but the persistence of her family and investigators ensured her story would not be forgotten. Her case highlights the transformative power of forensic science and the unwavering determination of those who seek justice for the voiceless.
For Robin Whitney and her family, the closure is both an ending and a new beginning — an opportunity to honor Tracy's memory while advocating for advancements that could bring closure to others.
