Hsu Tung-chih

Hsu Tung-chih (Chinese: 徐東志; 1947 – 14 May 1984) was a Taiwanese serial killer who killed at least seven people, including two girlfriends, from 1976 to 1983. Convicted, sentenced to death and subsequently executed for these killings, he is regarded as one of the worst murderers in the country's history.

Crimes First crime Hsu's first arrest came in 1973 when he was sentenced to 3 years imprisonment for assault, but the sentence was later reduced to a year and six months in accordance with the Criminal Sentence Reduction Act of 1964. While serving his sentence, Hsu's mother entrusted one of the prison wardens, Chang Jin-shu, a distant relative, to take care of him.

Release and first murder After he was released from prison, Hsu visited Chang and met his sister-in-law, Chang Lin-shu, and his niece, Bi-chun, who was Chang's daughter. He developed a romantic interest in the former, and the two started dating soon after.

On 29 January 1976, on the pretext of asking Bi-chun to help him repair his car, he took her from her house in Taoyuan's Guanyin District to his residence in Taipei, with Lin-shu following them soon after. After staying there for the night, Lin-shu asked Hsu for some money so she could return home to celebrate the Chinese New Year, but Hsu refused. She asked him again later that night, only for him to refuse again, prompting Bi-chun to threaten to end their relationship. In response, an angered Hsu grabbed her by the head and bashed her against the floor, killing her in the process.

Double murder In 1977, Hsu met Chiang Yu-yun, a hostess who had always wanted to move to Japan, with Hsu, in an attempt to please her, lying that he could smuggle her there. She later moved in with him and his business partner, Wu Cai, with three sharing an apartment. According to his own confessions, his primary motive was money, but another factor that led him to kill Chiang and Wu Cai was due to their affair. Prosecutors were quite puzzled at this move, as it implied there were victims they did not know about, but as the execution order had already been signed, it was difficult to investigate the matter. A theory suggested that this was simply a ploy to delay the execution, but it could not be confirmed with certainty. As a result, Hsu was summarily executed in Tainan Prison.
