Facebook Post:

In June 1977, three young girls arrived at summer camp in eastern Oklahoma, excited for their first night away from home.
Lori Lee Farmer was 8. Michele Heather Guse was 9. Doris Denise Milner was 10.
They were staying at Camp Scott, a wooded Girl Scout camp in Mayes County. They shared tent 7 in the Kiowa unit, an area set slightly apart from the counselors’ tents.
What many people do not realize is that weeks earlier, during a staff training session, a handwritten note had been found inside a doughnut box. It warned that someone intended to kill three girls at the camp. The note referenced a different tent number and was dismissed as a prank. Camp sessions went on as planned.
On the girls’ first night, storms moved through the area. Sometime in the early morning hours of June 13, the three girls were taken from their tent.
By sunrise, counselors noticed they had not reported for breakfast. A search began. Not far from the tent area, the girls were found along a path leading toward the showers. Investigators later determined they had been killed by strangulation and blunt force injuries and had been sexually assaulted.
The camp was evacuated. The case quickly became national news.
Investigators focused on Gene Leroy Hart, a local man with a history of violent sexual crimes who had escaped custody years earlier and knew the area well. He was arrested and charged, but when the case went to trial in 1979, the jury found him not guilty. Hart died in prison later that same year while serving time for earlier convictions.
Over the decades, questions have never gone away. The warning note. The camp’s layout. The handling of early evidence. Later forensic testing that fueled new confidence for some officials but never led to a conviction.
The murders remain officially unsolved.
Nearly fifty years later, the families of Lori, Michele, and Doris are still waiting for answers.
This is not just a story about a crime. It is a story about warning signs that were missed, an investigation under immense pressure, and a truth that was never fully resolved.
