Three young men from wealthy San Francisco Bay Area families spent more than a year working on their perfect crime.
They converted three prisoner transport vans, built an underground bunker to hold their hostages, even made a lead box to hold the $5 million in ransom they expected to collect to block radio signals if authorities inserted tracking devices.
Then they kidnapped a school bus full of children and buried them under mounds of dirt in a crime that haunts the victims nearly 40 years later.
"They basically stole our whole youth. Our childhood was completely turned upside down," said Jodi Heffington-Medrano, who was 10 at the time.
