The Yosemite Park Murderer

On Valentine's Day weekend 1999, three Yosemite National Park tourists disappeared and were found tragically murdered a month later. At the time, handyman Cary Stayner was questioned but released due to lack of evidence. Later that summer, when another woman turned up dead, Stayner would not be so lucky. Authorities were able to pin Stayner with all four murders.
