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. The rental car's location data, combined with Harald's inconsistent explanations about a flat tire and hand injury, created circumstantial evidence placing him in the gorge during the time Alice disappeared.
