Alice Ku, a California tutor, vanished in Taiwan's Taroko National Park in 2019 after a secret marriage to Harald Herchen. Her family's investigation uncovered digital evidence implicating him—a jury found him liable for her death, awarding $23.6 million, though he remains a fugitive without extradition. A family's persistence and resources enabled them to hire a private investigator who discovered crucial digital evidence, including an email sent from Alice's account after her disappearance that investigators determined she could not have written.
