In a remarkable breakthrough, DNA testing has finally revealed the identity of “Pipeline Pete,” whose remains were discovered near Granger, Wyoming in 1982. After 42 years of mystery, investigators have confirmed that the human remains belong to Jack Clawson, a man who went missing in 1981 while returning home to Missouri from a visit to his family in California. This groundbreaking discovery brings closure to Clawson’s family and highlights the remarkable advancements in forensic analysis that made it possible.
The Disappearance of Jack Clawson
Jack Clawson, a resident of Sedalia, Missouri, had traveled to Fremont, California, to spend time with his family in July 1981. Following his visit, Clawson was expected to return home for a hunting trip with his friends. However, when he failed to arrive as planned, his concerned family reported him missing.
The Discovery of Unidentified Remains
Over a year later, in August 1982, a group of pipeline surveyors stumbled upon human remains in the desolate desert near Granger, Wyoming, south of Interstate 80. At the time, the identity of the deceased was unknown, and an investigation and autopsy revealed no signs of foul play. Clawson, who likely died months earlier during the winter months, was believed to succumbed to exposure.
The Cold Case of “Pipeline Pete”
With no means of positively identifying the remains and connecting them to the missing person report filed in California, the “Pipeline Pete” case went cold for Sweetwater County detectives. The lack of leads and conclusive evidence presented significant challenges in progressing the investigation.
Advancements in Forensic Analysis
In May 2011, determined to solve a series of historical cases involving unidentified remains, including the tragic case of Christine Thornton, detectives from the Sweetwater Sheriff’s Office sought assistance from forensic analysts at the state crime lab. Together, they submitted biological samples to the University of Northern Texas Health Science Center for mitochondrial DNA analysis—an invaluable tool in establishing familial connections and identifying individuals.
Positive Match: Jack Clawson’s Identity Revealed
After years of relentless effort, the Sweetwater County detectives received a long-awaited breakthrough. In March 2023, the University of Northern Texas Health Science Center confirmed a positive match between the DNA from the unidentified remains of “Pipeline Pete” and Jack Clawson. The revelation finally connected the missing person report from California to the discovery in Wyoming.
A Moment of Closure
Sheriff John Grossnickle expressed his gratitude for the extraordinary advancements in forensic analysis and the collaborative efforts that led to the resolution of Jack Clawson’s case. He acknowledged the invaluable contributions of lead detective Stephanie Cassidy, the University of Wyoming Department of Anthropology, the Wyoming State Crime Lab, and the University of Northern Texas Health Science Center. With this identification, Clawson’s family can finally find closure after 42 years of uncertainty and grief.
Conclusion
The identification of Jack Clawson as “Pipeline Pete” after 42 years stands as a testament to the power of DNA analysis and the tireless dedication of law enforcement and forensic experts. This breakthrough underscores the significant advancements made in forensic technology, enabling the resolution of cold cases and providing closure to families with long-awaited answers. As the field of forensic analysis continues to evolve, it brings hope for solving more mysteries and reuniting families with their lost loved ones.
