Shen Jia-wun is one of the antagonists in Copycat Killer, a crazed DJ who has an immense hatred for women. The character is portrayed by Fandy Fan.
When Da-chao convinces Hsiao-chi to continue investigating Jian-ho in the serial murder case, it leads them to learn about Shen Jia-wun, the DJ at Club KINK and an old classmate of Jian-ho.
He turns out to be a very suspicious individual and Hsiao-chi finds a lot of evidence tying him to the crimes but is thwarted when Jia-wun is suddenly backed by a hotshot lawyer. Hsiao-chi chips away at the clues to find a way to bring in Shen Jia-wun.
Just a replacement
All the rage that Shen Jia-wun had inside him stemmed from his complicated childhood. His mother had a daughter before him who died very young and this led to her having a psychotic break.
When he was born, she gave him the same name as her daughter and pretended that he was a girl to recapture that feeling but Shen Jia-Wun felt humiliated and unloved.
He would hallucinate a young girl and refer to it as the ghost or spirit of his sister which would push him to commit horrific acts. He beat up the girls who bullied Jian-ho in school which is how they became friends.
When Hsiao-chi brings Jia-wun in for questioning, he almost gets him to admit to the murders but a lawyer walks in a gets him out of there. The lawyer works for the Speaker of the House and Hsiao-chi and Yan-jhen find out that Jia-wun might be his illegitimate son.
In bad company
Shen Jia-wun met Chen He-ping at the SODOM club along with his other accomplices. He would kidnap the women and torture them along He-ping while Tian Cun-yi took pictures of the entire thing.
Jian-ho doubts Jia-wun’s role in the murders but doesn’t feel like betraying him as Jia-wun is the one who stood by him when he was growing up and going through a tough time.
Shang-yong follows Jia-wun one day and attacks him to find out where his daughter is kept but Jia-wun comes out of that fight alive while Shang-yong is gravely injured and subsequently hospitalized.
Jia-wun remains in hiding, slowly losing his head until he decides to take Yu-tong to a different location. Jian-ho shows up after Jia-wun calls him but when Jian-ho asks him to turn himself over, he knocks Jian-ho out with a rock and places him in the car as well.
As he’s driving, he once again sees his sister, and despite Jian’ho’s best efforts, Jia-wun drives the car off the clip to end his pain and suffering.
