The Stayner Brothers: One Was Kidnapped at 7. The Other Became the Yosemite Killer.

In 1972 a convicted child predator took seven-year-old Steven Stayner off a Merced, California street and raised him under a fake name for seven years. Steven came home a hero. His older brother Cary did not, and by 1999 he was the Yosemite Killer. This is the story of one family, two brothers, and every system that failed them along the way.
