Kay Medin, a 48-year-old school teacher, went missing from her rural home in Northern California back in 1987. Her husband, Nickolas Medin, reported her disappearance to the authorities upon returning from a business trip and finding her not at their Hyampom residence. Despite extensive searches and interviews with friends and family, Kay seemed to have vanished without a trace, leaving behind all her belongings and her car.
The disappearance was quickly deemed suspicious, prompting a thorough investigation by the Trinity County Sheriff’s Office. The case took a chilling turn on November 25, 1987, when the Humboldt County Sheriff’s Office received a package containing skeletal remains believed to be Kay’s. Accompanying the remains was an anonymous letter with a vague map leading authorities to another location where more remains were found, positively identified as Kay through dental records. The remains were not buried, and a death certificate was issued for Kay the following year.

A significant development in the case occurred years later, in 1993, when a partial skull was discovered on a beach near Trinidad Head, about 150 miles away from where Kay’s initial remains were found. Despite extensive efforts to match the DNA from the skull with any missing persons records, it wasn’t until genetic genealogy testing by the private forensic lab Othram Inc. in 2024 that the skull was identified as belonging to Kay.
With the confirmation of the skull being Kay’s, the investigation into her disappearance and death has been reignited. Humboldt County Sheriff’s Office cold case investigator Mike Fridley is hopeful that this breakthrough will prompt individuals with information related to the case to come forward. Despite the passage of time, Fridley believes that there may still be individuals holding crucial information that could help bring closure to the case and serve justice for Kay.
The case has left many questions unanswered, particularly concerning the anonymous letter sent to the authorities containing the skeletal remains and the motive behind the mysterious disappearance of Kay. With Nickolas Medin, Kay’s husband, having passed away in 2018, the search for answers now relies on potential witnesses or individuals with information about the events surrounding Kay’s disappearance.
As authorities continue to delve into the details of the case and seek justice for Kay Medin, the hope remains that the recent identification of her remains will lead to further breakthroughs and potentially bring closure to this decades-old mystery. The Humboldt County Sheriff’s Office has urged anyone with information pertaining to the case to come forward and assist in shedding light on the circumstances surrounding Kay’s disappearance and tragic demise.
