Horror In Yosemite

In 1999, three women went missing in Yosemite National Park, launching the largest search and rescue operation in US history.  The bodies of two of the women are found in a burned car, and the third is only found when the killer sends a taunting note to the FBI.  Five months later, when a fourth woman is found beheaded near the park, the Bureau believes a serial killer may be on the loose.
