Casepin holds 11 solved cases in Taiwan. A solved case is one the record closes with a conviction or an equivalent legal finding; each file names who was convicted only where a court did.
SOLVEDListenPurple Garden Hotel, Datong District, Taipei, Taiwan · 2018
Amber Poon Hiu-wing, a pregnant 20-year-old from Hong Kong, was killed by her boyfriend Chan Tong-kai in a Taipei hotel room in February 2018. Jurisdictional gaps meant Chan could only be prosecuted in Hong Kong for money laundering, and the case became the stated rationale for a 2019 extradition bill that triggered months of mass protests in Hong Kong.
