In 1980, murdered the morning after her 21st birthday

On July 12, 1980, a 21-year-old woman named Susan Vesey was found murdered inside her apartment on Casino Road in Everett, Washington — the morning after her twenty-first birthday. It was her husband, Ken Vesey, who discovered her body. The killing sent a shock through the local community, and in the days that followed detectives were left with a homicide scene and few clear leads. It would take forty-six years to name the person responsible.

Investigators in 1980 worked the case with the tools they had: interviews, a careful examination of the crime scene, and the physical evidence they could collect and preserve. No suspect emerged, and no clear motive was ever established. The case quickly went cold and passed into the Everett Police Department's cold case files, where it was reviewed periodically over the decades in the hope that forensic science would eventually catch up to the evidence sitting in storage. For the Vesey family, that hope stretched across nearly half a century of not knowing who had killed Susan, or why.

That hope was finally realized earlier this year. On March 13, 2026, the Everett Police Department announced that modern DNA analysis had at last identified a suspect in Susan Vesey's murder: Mitchell Gaff, a man in his sixties. The genetic material recovered from the 1980 crime scene — evidence that could not be meaningfully analyzed at the time, because DNA profiling would not become a standard investigative tool until the late 1980s and early 1990s — was re-examined with contemporary techniques and matched to Gaff, who had managed to evade detection for close to five decades.

Prosecutors moved forward with the most serious homicide classifications available under Washington State law. Gaff was charged in Snohomish County Superior Court with Aggravated Murder and Murder in the First Degree in connection with Susan Vesey's death. After nearly 46 years, the case that had haunted Snohomish County finally had a named defendant.

Gaff's alleged violence, investigators say, did not begin and end with Susan Vesey. In May 2024 — more than a year before the Vesey charges were announced — the Everett Police Department had already arrested and booked Gaff in connection with a separate Everett murder: that of Judy Weaver, who was killed on June 2, 1984. Two women, two unsolved homicides in the same city, four years apart, both now attached to the same suspect. The earlier arrest in the Weaver case provided investigators with additional context as they built toward charging Gaff in the older Vesey killing.

The resolution of the Vesey case underscores something cold case investigators have long argued: evidence that seems unpromising at the moment of collection can become the key to a case decades later. The material gathered in that Casino Road apartment in 1980 was collected before the technology to analyze it even existed. It sat, intact and analyzable, until dedicated cold case work and advances in DNA analysis could finally give it meaning. Across the country, cold case units have adopted the same discipline — systematically revisiting unsolved homicides, applying new forensic methods to old evidence, and reopening cases that families and detectives alike had feared would never be answered.

For the Everett community, Casino Road held the memory of a young woman's death for the better part of five decades. The announcement that a suspect had at last been identified and charged carried a mix of emotions — relief that the mystery might finally be closed, and grief that it had taken so long. It is worth stating plainly that the charges of Aggravated Murder and Murder in the First Degree remain allegations: Mitchell Gaff has been charged, not convicted, and the case has yet to be tried. But for the Vesey family, after forty-six years of silence, even the naming of a suspect represents a measure of accountability that once seemed impossible — a reminder that, for a thorough investigation and for the people who loved Susan Vesey, justice is not bound by time limits.
