Chan Tong-kai, 20, wanted in Taiwan for the murder of his pregnant girlfriend during a holiday the two Hong Kongers took there in 2018, walks out the Pik Uk Prison in Hong Kong on October 23, 2019, after serving a short jail sentence for stealing his girlfriend's possessions. - Chan's case, where he fled back to Hong Kong where Taiwanese police were unable to apprehend him because there is no extradition agreement between the two territories, triggered an ill-fated proposal by Hong Kong's pro-Beijing government to ram through a sweeping extradition bill, which would have allowed the city to extradite suspects to any territory including the authoritarian mainland.
