On the morning of July 22, 2010, a 15-year-old boy attacked his 42-year-old mother and 12-year-old sister with a knife inside their family apartment on Heung Wo Street in Tsuen Wan, Hong Kong. Both victims died as a result of the attack. The boy reportedly admitted to the killings, though the motive was not made clear in initial reporting.
Following the incident, the teenage suspect was charged with two counts of murder, an offense that carries a potential life imprisonment sentence under Hong Kong law. Because of the suspect's age at the time of the killings, the case prompted public discussion about juvenile culpability and mental health in the context of serious violent crime. The case drew significant public attention in Hong Kong due to the severity of the crime and the young age of the person responsible. It became part of broader public conversations about juvenile delinquency, mental health support, and family dynamics in the city. More than a decade later, the case gained renewed attention when it served as the basis for the 2024 Hong Kong film Papa, directed by Philip Yung and starring Sean Lau Ching-wan. The film centers on the emotional aftermath of the killings, focusing in particular on the grief experienced by the surviving father rather than dramatizing the crime itself. Papa was commercially successful, ranking as the ninth highest-grossing Hong Kong film of 2024, and was well received by critics, with particular praise directed at Sean Lau's performance. The film received 11 nominations at the 43rd Hong Kong Film Awards, and Lau went on to win a Hong Kong Film Award, a Hong Kong Film Critics Society Award, and an Asian Film Award for his role.
