"Decade-long quest to prove parents' involvement in sister's death unpacked in new true crime docuseries"
HBO's new docuseries "Burden of Proof" follows Stephen Pandos as he spends a decade trying to prove that his parents were responsible for the unsolved disappearance of his 15-year-old sister in 1987. The four-hour documentary is a textured portrait of a tortured soul chasing maddeningly elusive truth, and while it never quite reaches resolution, it remains haunting and engrossing.
