Buried in the Backyard: Amber Dubois Vanishes on Walk to School

In 2009, 14-year-old Amber Dubois went missing while walking to school in Escondido, California. Investigators were initially suspicious of her mother's live-in boyfriend, Dave Cave, because the two had a strained relationship and bickered often. Amber's mother, Carrie McGonigle, started suspecting the worst, but Cave was never identified as a suspect.
