Alice Ku, a 36-year-old tutor from Mountain View, California, vanished during a trip to Taiwan with her husband, Harald Herchen, in late November 2019. The couple arrived in Taiwan on November 23, 2019, for what was described as a business trip. Ku was last seen on November 29 after being dropped off at a train station in Hualien; she was supposed to visit her parents near Taipei but never arrived and her family said they did not know she planned that visit.

Investigators noted inconsistencies in Herchen’s account. Taiwan’s Criminal Investigation Bureau reported evidence suggesting an email Herchen said came from Ku after she left was actually sent from the same location where he was staying. Authorities believe Ku was murdered on or before November 29, 2019, and Herchen has been identified as a suspect; Ku’s body has not been found and he remains wanted for questioning. Her family filed a wrongful death suit against Herchen in 2021.

Does anyone have information about Ku’s movements in Taiwan between November 23 and November 29, 2019, or recall seeing her at the Hualien station on November 29?
