On the evening of June 13, 1977, three teenage girls—Doris Denise Milner, 14, Shirley Ybanez, 14, and Mary Katherine Robinson, 15—were found slain at Camp Scott, a Girl Scout camp in Mayes County, Oklahoma. The victims had been bludgeoned and their bodies left in a wooded area near their tents. Despite a multi-agency investigation, multiple suspects, and high-profile leads over the decades, no one has been charged in connection with the killings. This article presents a verified, long-form account of the case, covering background, investigative milestones, persons of interest, and the ongoing status of the case.

Background of Camp Scott and the Night of the Crime
Camp Scott was a Girl Scout facility located in a rural area of northeastern Oklahoma, near the community of Locust Grove. In June 1977, it hosted a weeks-long summer camp session for teenage girls. On the night of June 13, counselors conducted a routine nightly headcount and tent check around 11:30p.m. and noted that everything appeared secure. Shortly after midnight, a counselor returning from a restroom break observed an unidentified man near the camp’s perimeter. No immediate alarm was raised, and the incident was not communicated effectively across shifts. Later that night, the bodies of the three girls were discovered in a wooded area close to their assigned tents, triggering a major criminal investigation.
Initial Response and Discovery
Upon the bodies’ discovery, local law enforcement, the Oklahoma State Bureau of Investigation, and federal authorities from the FBI converged on the scene. The victims had sustained severe blunt-force trauma; investigators concluded the killings were premeditated and carried out by someone familiar with the camp’s layout and schedules. The camp’s layout, with rows of tents set among trees, created challenges for scene preservation and early evidence collection. Due to the remote location and limited forensic technology available in 1977, many physical clues were difficult to recover or interpret with certainty. Nevertheless, a wide canvas of staff, visitors, and local residents was conducted in the immediate aftermath.
Investigation and Persons of Interest
Early Suspects and Confessions
In the days following the murders, investigators interviewed numerous individuals, including transient workers and local residents with histories of violence. Two juvenile suspects were initially taken into custody and confessed to the killings; however, those confessions were later recanted. Legal proceedings against the minors were stayed, and they were ultimately released due to lack of sufficient evidence to proceed with adult charges. Over the years, multiple other persons of interest emerged, including individuals with known criminal histories and behavioral patterns that drew attention, but none were formally charged.
Forensic Review and Cold-Case Techniques
As forensic science evolved, the case was revisited using more advanced techniques, including DNA analysis where viable biological material was located. Despite these efforts, leads did not yield enough probative evidence to identify a specific perpetrator beyond a reasonable doubt. The OSBI and FBI maintained the case as open, periodically reviewing tips and—during periods of heightened public attention—releasing information to generate new leads. Advances in forensic genealogy later prompted limited, targeted reviews, but these too failed to produce actionable matches that could stand up in court.

|---|---|---|
| June 13–14, 1977 | Discovery of the murders; initial response | Established the core facts and early investigative actions |
| 1977–1980 | Juvenile suspects questioned and confessions recanted | Highlighted challenges in evidence and juvenile interrogations |
| 1990s | Case transferred to OSBI; continued periodic review | Demonstrated long-term institutional commitment |
| 2000s–2010s | Cold-case reviews, DNA and forensic genealogy attempts | Illustrates evolving methods applied to historical crimes |
| Post–2010s | Status remains open; periodic public appeals for information | Maintains awareness and encourages new information |
Official Status and Challenges
Law enforcement agencies, including the Oklahoma State Bureau of Investigation and the FBI, classify the Camp Scott murders as an unsolved cold case. The primary challenges include degraded physical evidence, the passage of time affecting witness recall, and the inability to corroborate confessions with forensic proof. Investigators have periodically appealed to the public for information, emphasizing that advances in technology could one day make resolution possible. Legal constraints regarding juvenile records and the death of key witnesses have further complicated efforts to close the case.
Impact on Community and Victims
The murders cast a long shadow over Camp Scott and the broader Mayes County area, prompting changes in security protocols at youth camps and influencing regional crime-prevention policies. Advocacy by the victims’ families has underscored the enduring emotional toll and the importance of sustained investigative attention. Documentaries, true-crime coverage, and victim-impact statements have kept the case in public discourse, ensuring that memories of Doris Milner, Shirley Ybanez, and Mary Katherine Robinson remain part of the regional narrative. Their lives are often remembered in community memorials and observances focused on youth safety.
Enduring Questions and Investigative Outlook
Key unresolved questions include the identity of the assailant(s), the precise sequence of events on the night of June 13, 1977, and whether physical evidence still exists that can be re-examined with modern technology. Agencies continue to treat the case as open, and the OSBI encourages anyone with information to come forward. While the passage of time reduces the likelihood of traditional prosecutions, advances in forensic science and public engagement keep the possibility of new leads alive. The case remains a sobering example of how complex and enduring violent crimes can be, even in seemingly safe, structured environments like summer camps.
For investigators, journalists, and the public, the Camp Scott murders represent a persistent investigative challenge and a call to remember victims thoroughly and systematically. Ongoing transparency about the status of the case and careful application of new investigative techniques offer the best chance of eventual resolution, if not in courtrooms, then at least in historical clarity.
