On January 29, 1994, hikers walking through the remote redwood forest of Pogonip Open Space Preserve in Santa Cruz, California, discovered the partially buried remains of a young female. She had been brutally beaten, strangled, and struck with a metal pipe. Known for nearly two decades only as ‘Pogonip Jane’, the case stood as one of Northern California’s most poignant unidentified decedent mysteries. In November 2013, the California Department of Justice and the Santa Cruz County Sheriff’s Office utilized cutting-edge familial DNA searching to officially identify her as seventeen-year-old Arizona runaway Kori Lamaster, restoring her name and re-energizing the search for her killer.
The 1994 Redwood Discovery & Crime Scene Reconstruction
On January 29, 1994, two hikers navigating a secluded trail near the northern boundary of Pogonip Open Space Preserve—a 640-acre forested park adjacent to the University of California, Santa Cruz—spotted a shallow grave beneath fallen redwood boughs and soil. Santa Cruz County Sheriff’s detectives and coroner examiners exhumed the remains.
The victim was estimated to be a young Caucasian female between 15 and 20 years old, wearing a distinctive wire ring on her left thumb and a turquoise bracelet. The post-mortem examination determined the cause of death to be massive blunt force head trauma inflicted with a heavy blunt weapon, accompanied by asphyxia. Pathologists extracted bone samples and dental records, carefully logging physical characteristics and preserving skeletal DNA in California state archives.
Nineteen Years of Dead Ends & Facial Reconstructions
Over the subsequent nineteen years, detectives pursued dozens of missing person reports across California, Oregon, and Washington. Forensic artists created multiple 2D and 3D clay facial approximations broadcast on regional news channels and entered into the National Missing and Unidentified Persons System (NamUs).
In 2007, California DOJ forensic scientists extracted a complete Short Tandem Repeat (STR) mitochondrial and nuclear profile from the victim’s femur bone, entering it into California’s Unidentified Persons DNA Database. However, because no family reference samples existed in the missing persons database, Pogonip Jane remained unidentified.
The Familial DNA Breakthrough & Identification of Kori Lamaster
In 2013, California DOJ forensic scientists performed a statewide familial search across the state’s DNA database. The algorithm detected a high-probability kinship match between Pogonip Jane and a reference DNA profile submitted years earlier by an Arizona family searching for their missing daughter, Kori Lamaster.
Kori Lamaster had vanished from Mesa, Arizona, in 1993 at age 17 after traveling toward California. Direct nuclear STR comparison against reference swabs provided by Kori’s mother confirmed a 100% biological match in November 2013, officially closing the 19-year unidentified decedent case.
Active Homicide Manhunt & Continuing Forensic Pursuit
With her identity restored, Santa Cruz County Sheriff’s detectives re-interviewed associates from Kori’s 1993 travel route through California. Preserved physical evidence from the 1994 Pogonip crime scene is currently undergoing advanced touch DNA analysis and forensic genetic genealogy to identify the male perpetrator responsible for her murder.
The case stands as a milestone in California familial DNA search jurisprudence, proving that unidentified persons databases can resolve long-standing missing person cold cases across state lines.
Forensic Anthropology & Pogonip Park Recovery
On January 29, 1994, hikers in Pogonip City Park near the University of California, Santa Cruz, discovered human remains concealed in a shallow grave beneath redwood canopy. Santa Cruz County Sheriff-Coroner investigators and forensic anthropologists determined that the victim was a female between 17 and 24 years old who died from multiple crushing skull fractures caused by a blunt instrument.
Without identification, the decedent was designated ‘Pogonip Jane.’ Forensic artists produced multiple 2D and 3D facial approximations, and isotopes from bone samples suggested she was a native of the Pacific Northwest. For nearly two decades, her profile was cross-referenced against missing persons nationwide without a match.
Familial DNA Search & Department of Justice Breakthrough
In 2013, the Santa Cruz County Sheriff’s Office cold case unit submitted skeletal DNA extracted from Pogonip Jane to the California Department of Justice DNA Laboratory in Richmond. Criminalists generated a full STR profile and submitted it for a specialized familial DNA search within the California state database.
The familial search returned a statistical parent-child kinship link to a biological sample provided years earlier by a family in Washington State searching for their missing daughter. Formal mitochondrial and nuclear DNA comparison confirmed that Pogonip Jane was seventeen-year-old Kori Lamaster of Mesa, Washington, who had disappeared in 1993.
Ongoing Cold Case Homicide Investigation
The restitution of Kori Lamaster’s identity transformed an unidentified remains inquiry into an active homicide investigation. Santa Cruz County Sheriff detectives traced her final movements along the Interstate 5 corridor and coastal Highway 1, gathering new witness accounts and identifying potential persons of interest from the 1993-1994 timeframe.
The case highlights the vital role of state-sponsored familial DNA database searches and cross-jurisdictional cooperation in solving historical unidentified decedent cases across the United States.
Isotope Geochemistry & California Department of Justice Familial Search
Prior to the genomic identification of Kori Lamaster, forensic anthropologists utilized stable isotope analysis of bone collagen to map the geographic origins of Pogonip Jane. The isotopic ratios indicated childhood residence in the Pacific Northwest, focusing regional missing person inquiries on Washington and Oregon state records.
When the California Department of Justice executed the familial DNA search in 2013, the high-stringency statistical match between the skeletal STR profile and the Lamaster reference sample provided a posterior probability of kinship exceeding 99.99%, demonstrating the exceptional efficacy of state-maintained familial databanks in resolving historical missing child cases.
Active Highway Corridor Homicide Profiling & Regional Task Force
Following the identification, the Santa Cruz County Sheriff’s Office cold case unit integrated Lamaster’s travel timeline with the FBI’s Highway Serial Killings (HSK) database, examining transient long-haul patterns along Highway 1 and Interstate 5 to identify potential predatory offenders active in 1993.
Investigators have re-analyzed physical evidence recovered from the Pogonip redwood grove using modern touch-DNA vacuum extraction (M-Vac), seeking trace cellular material left on ligatures or buried items. The ongoing investigation illustrates how restoring the identity of a long-unidentified decedent re-energizes active homicide leads decades after the crime.
Santa Cruz County Coroner Archival Review & Forensic Reconstruction
The resolution of the Pogonip Jane case was made possible through the meticulous record-keeping of the Santa Cruz County Coroner’s Office. Original anthropological charting, odontological radiographs, and crime scene photographs taken in January 1994 were maintained in high-resolution digital archives.
When modern mitochondrial sequencing was compared against the Lamaster family reference samples, the statistical congruence across maternal haplogroup markers eliminated any possibility of coincidence. The formal restitution of Kori Lamaster’s name brought closure to a decades-long search and demonstrated that no cold case is truly beyond resolution when science and perseverance converge.
