Chen Jui-chin

On April 19, 2013, Chen Jui-chin was executed in Taichung Prison (now located in the Taichung Detention Center).

On April 19, 2013, the Minister of Justice, Tseng Yung-fu, signed an execution warrant for Chen Jui-chin. Chen complained that the prosecutor had done just to settle old scores. In retaliation, Attorney Liu countered his words, saying: "Put your grievances to rest, as the court has made a very clear investigation." Liu also silently chanted an old mantra, and prayed that the convict's soul be sent to Sukhavati. Chen Jui-chin took a deep and hearty inhale, but as the drugs administered weren't enough to kill him, he was induced into a coma and subsequently shot in the head. He was 63 years old.

Between 2011 and 2013, Chen Jui-chin appealed to the Taichung Branch of the Taiwan High Court a total of eight times for a retrial, all of which were rejected. A protest was filed for the Supreme Court in 2011, but it was also dismissed.

In December 2004, the Chiayi District Court sentenced Chen Jui-chin to five death sentences and one life sentence. At a fifth trial the Tainan Branch of the Taiwan High Court reduced to sentence to a 20-year-old fixed imprisonment term, because of his cooperation with punishment regulations and the application of commutation changes in law. He still remained with a death sentence for the murder of Chen Yi-ling, and the appeal for it was rejected by the Supreme Court. While on death row, he was detained at the Taichung Detention Center.

In May 2003, Chen Jui-chin met Chen Yi-ling, a female insurance saleswoman, with whom he started a romantic relationship. He noticed that she had considerable savings, and asked his new girlfriend to borrow some money for his mortgage, to which she replied that she would consider it. Although the pair only knew each other for two days, Chen Jui-chin planned to kill her directly and then rob her. He invited Chen Yi-ling by telephone to the Wu Xian Emperor's Temple on Xiangrong Street, in West Chiayi. From there, he took her to Zhushan in his black jeep. While there, he opened a capsule of sleeping Baogan Pills, and put sleeping powder in it. When Chen Yi-ling fell asleep, Chen Jui-chin tied her hands with nylon rope. When she awoke, Chen Jui-chin told her that he wanted to play, and so he beat and eventually strangled his girlfriend into unconsciousness. When he saw the unconscious Chen Yi-ling, he suddenly felt aroused and attempted to have sex with her, but because of his sexual dysfunction, he instead sexually assaulted her. After he finished, Chen Jui-chin contemplated throwing Chen Yi-ling off a cliff, but unbearing of the thought of not stealing something, he robbed her of her gold Rolex watch, jadeite necklace, rings, $1 million NT in cash, credit and ATM cards, mobile phones and two blank checks. He then hit Yi-ling with a stone and beat her to death, throwing her body off the mountain cliff. After disposing of the corpse he went to Taipei with his other casual girlfriend, Xiao. On the way, he gave her the Rolex. He also held onto the deceased Chen's bank cards, but couldn't take the money because he didn't know the password. The attempted theft was detected by the authorities, and Chen was arrested.

Chen was arrested on 22 May 2003, at the Chiayi Christian Hospital, where he was seeking treatment for injuries suffered during a beating. Following his arrest, Chen Jui-chin confessed, in order, to killing Chen Yi-ling, Tseng Pi-hsia, his three children, and Wang Shu-ying, but claimed that he had nothing to do with the disappearances of his other female friends. After his death sentence was upheld, he retracted his confession and offered to help the police in locating the missing women, but his bluff was called out, as the investigators understood that he was just trying to weasel out of his execution. Chen Jui-chin was indicted by the Nantou District Prosecutors' Office in July 2003 on charges of rape and murder for the death of Chen Yi-ling. The prosecution sought the death penalty.

In 2000, many insurance companies discovered that the circumstances surrounding the deaths of Chen's relatives, especially his three sons, whom all received "head injuries" and died from cerebral edema, were suspicious, as all of them had been insured for millions of NT. After holding discussions with representatives of various companies, they unanimously agreed to prevent Chen Jui-chin from insuring people and reported this to the police. The then-legislator, Chen Chao-jung, was informed of this ordeal, and soon held a press conference expressing his doubts about the suspect. Chao-jung himself would later personally go and interrogate Chen, who, out of fear, hid under the table and refused to come out. The next day, he angrily announced before the media that he would "retain the right to pursue the lawsuit against the false accusations of legislators."

Chen's late wife often visited a clothing store owned by a woman named Yan Liqin, a widow with two children. After more than a month from his wife's death, Chen took the initiative to "entangle" himself around the clothing store. After strenuous pursuit, Yan was moved, and they married in 1997. Chen's vicious behavior was unchanged, however, as he tried to fraudulently clear his debts the following year. Yan's 16-year-old son was having a headache, so Chen fed him sleeping pills, claiming that they were painkillers. While the son was sleeping, Chen transported him to the stairs, where he dropped him on his head, creating the illusion of an accidental death. He applied for an insurance claim of $15.5 million NT, but the insurance company, which had noticed that multiple relatives had died of suspicious injuries relating to head trauma, paid only $250,000. Since Yan also believed that her son had been murdered, she continued to investigate for possible evidence to prove it. Perplexingly, Chen tried to deceive his wife by putting on a condom on the boy's genitalia and explaining that he had died while having sex. Yan remained with him for a while, but as they relationship worsened, she divorced him. During the divorce, she was intimidated by Chen to pay a $1.2 million NT "breakup fee", but was otherwise left unharmed.

In 1996, Chen learned that his second wife, Wang Shu-ying, had been coveting insurance claims and real estate for teachers. Under the pretense of going on a trip, the two drove to Xingang. Suddenly, Chen stopped the car, pulled out a wooden stick from under the driver's seat and beat his wife to death. After the murder, Chen dumped her body on Shixian Road in Chiayi, creating the illusion of a car accident. Since he had blood on his clothes, Chen was reluctant about catching a taxi back home. In this case, not only did he obtain Wang's insurance claims of $11.37 million NT, but also continued to receive her pension.

In 1995, facing another financial crisis, Chen targeted his own 15-year-old son. He took him to a heavy ornamental stone and hit the boy on the back of the head, cracking his skull. Chen lied about his son having died in a car accident, and fraudulently received $4.72 million NT.

In 1988, Chen Jui-chin was heavily indebted and desperate for money. In order to obtain a fraudulent compensation of $4.6 million NT, he pretended to discipline his 15-year-old adopted son, slapping him so hard that the child fell and hit his head on the concrete wall. The child died as a result from the injury, with Chen claiming that it was an accident.

Chen married his first wife, Tseng Pi-hsia, in 1974. They had a son and two daughters together. On New Year's in 1985, Tseng accidentally slipped in the bathroom and suffered a concussion. Instead of helping his wife, Chen dragged her off the bed and slammed her head into the ground several times, killing Tseng. He lied by claiming that she had fallen off the bed and died of intracranial hemorrhage, swindling $2.35 million NT in insurance money. Only six months after her death, Chen remarried to an elementary school teacher named Wang Shu-ying. Wang had a son from a previous marriage, whom Chen adopted.

Chen Jui-chin (Chinese: 陳瑞欽; pinyin: Chén Ruìqīn; July 25, 1949 – April 19, 2013) was a Taiwanese serial killer and one of the country's most infamous criminals. Because of his gambling addiction, he owed debts to loan sharks, and in order to pay them off, he turned towards violence. He murdered his spouse and three children, and fraudulently used their life insurance to amass $38 million NT, for which he was sentenced to 20 years imprisonment. Finally, he was sentenced to death for raping, robbing, and killing his girlfriend, Chen, from whom he stole millions worth of money. In total, he is suspected of killing eight people, including two female friends. In the media, he was nicknamed The Chiayi Demon.
