DeepSummary
In June 1983, a partial human hand was discovered in Yosemite National Park's Summit Meadow by visitors. Park rangers Don Coelho and Kim Tucker investigated the gruesome find, but had few leads to identify the victim. Over a year later, serial killer Henry Lee Lucas confessed to murders across the U.S., including in a mountainous California national park, potentially implicating him in the Yosemite case.
The investigators interviewed Lucas, who provided chilling details about crimes matching open cases. Though his confessions raised skepticism, some were corroborated. Lucas claimed to have killed over 100 victims nationwide from the 1970s to 1980s, motivated by a disturbing obsession. His troubled childhood of abuse and trauma was seen as a factor in his psychopathy.
Piecing together Lucas' travels, the rangers determined he could have been in Yosemite in 1982 when the victim likely died. While unable to conclusively link him to the crime, the bizarre case highlighted the challenges of wilderness investigations and the emergence of serialkiller phenomena in that era.
