38 Days of Terror: The Full Record of the Kidnapping of Hong Kong Tycoon Huang Kun

In September 2015, Hong Kong tycoon Huang Kun went missing in New Taipei while seeking medical treatment and was later found to be kidnapped. Two weeks later, the kidnappers demanded a ransom of 70 million HKD paid in Bitcoin, marking Taiwan's first virtual currency extortion case.
Police used a video Huang recorded to identify his location of captivity. On the 38th day, they successfully rescued him and identified the suspects and their accomplices. The case highlights the role of technology in modern crime tactics.
