‘Castleberry Kate’ Remains Found with Bullet in Skull Identified as Teenage Runaway After 37 Years

The identity of a young woman whose skeletal remains were discovered in Bullhead City, Arizona, has finally been confirmed after more than three decades. The Bullhead City Police Department announced on June 5 that the victim has been identified as Sonya Alice Langan, thanks to advances in forensic genetic genealogy.

Langan’s remains were unearthed in a vacant lot in May 1989 by a construction crew. At the time, investigators estimated that the victim was between 17 and 19 years old and had likely been deceased for a period of two to ten years prior to the discovery of her remains. A bullet was recovered from her skull, leading authorities to classify her death as a homicide. For years, Langan was referred to as “Castleberry Kate,” a name derived from the area near where her remains were located.

The case remained unsolved for years, and it was not until 2024 that a significant breakthrough occurred. The Bullhead City Police Department, in collaboration with the Mohave County Sheriff’s Office, secured funding to conduct forensic genetic genealogy testing. Samples from the investigation were submitted to the DNA Doe Project, which is dedicated to helping identify unidentified remains using advanced genetic techniques. By late 2025, the investigative team achieved a 99% genetic match, leading them to Langan’s identity.

Investigators then reached out to surviving relatives, only to discover that Langan had never been formally reported missing. Family members informed police that she had left her home around 1982 when she was just 17 or 18 years old. They elaborated that the reasons for her departure might have stemmed from strained familial relationships and periods of absence from home, suggesting that her departure was voluntary.

Relatives recounted Langan’s life before her disappearance, noting that she had dropped out of Kingman High School as a freshman in 1979. The family later moved to Bullhead City, where Langan was known to have worked at a local Burger King. Investigators obtained DNA samples from her relatives, which ultimately confirmed her identity. In May 2026, following the results of the DNA testing, Langan was formally identified.

The announcement has reignited interest in the case, which has been left unsolved for almost four decades. Although Langan has been identified, the investigation into her homicide remains open. Authorities are keen to learn more about the circumstances surrounding her death and have urged anyone with information to come forward.

The police department is actively seeking assistance from the public, encouraging individuals with relevant information about Langan’s life, disappearance, or homicide to reach out directly to detectives. This breakthrough not only provides closure for Langan’s family but also highlights the significant role that advancing forensic technology can play in solving cold cases.

As the investigation progresses, it sheds light on the importance of forensic genetic genealogy, which has revolutionised the field of missing persons and unidentified remains. Langan’s story serves as an important reminder of the enduring impact of unresolved cases on families and communities.

This identification marks a significant chapter in the long and painful journey for Langan’s relatives, who have grappled with uncertainty for many years. Moving forward, the Bullhead City Police Department remains dedicated to uncovering the truth surrounding her tragic fate, while also honouring her memory.
