(I've planned this homicide since 5th Grade, and I have no regrets about my crime. I actually feel comfortable now, because I have now fulfilled my dream.)
~ Cheng's confession.

Cheng Chieh (鄭捷; April 3rd, 1993 - May 10th, 2016) was a student responsible for the 2014 Taipei Metro Attack which caused 4 deaths and 24 injuries.


Cheng was born on April 3rd, 1993 and grew up in Taipei. He was extremely focused on studies and had a black belt in Taekwondo. He enrolled in the Chung Cheng Institute of Technology in 2011 but was expelled two years later. He then transferred to Tunghai University in 2013.

According to his high school and friends, Cheng has a natural talent and interest in Languages but his parents wanted him to be enrolled in Engineering. Since then Cheng has lost interest in studying and was expelled after failing.

Metro Attack

On May 21st, 2014, Cheng bought two fruit knifes, a Swiss Army knife, and had breakfast with a friend before starting the massacre.

Cheng stabbed three people on the Metro before chasing and hacking any passengers with his knifes. When the metro arrived Jiangzicui station, Cheng chased that fleed and also targeted passengers on the station. He was then tackled back a 62 year-old elderly. Other passengers took the opportunity to surround Cheng and restrained him.

The police arrived shortly after the attack and Cheng was arrested.


On July 21, 2014, Cheng was charged with four counts of murder and twenty-two counts of attempted murder.

When standing on trail Cheng made no attempt to hide his lack of remorse despite knowing full well it would make his pursectors more inclined to punish him as he revealed that he'd been planning the Taipei Metro Attack since he was in the 5th grade and plainly admitted with pride that he felt no remorse for his wrong doing and was twistingly proud of it.

On March 6, 2015, Cheng was found guilty and executed on May 10, 2016.
