On the night of August 28, 2007, Lin Hongsong, the prosecutor of the Shilin District Prosecutor’s Office (now the director of the Political Style Office of the Investigation Bureau), who was about to be transferred from the Public Prosecution Team to the Investigation Bureau, counted the documents the night before reporting for duty. Nearly 300 files were piled up like a mountain, and he felt half cold. At this moment, a fragrance suddenly wafted. Lin Hongsong wondered: “Where did the perfume smell come from in the middle of the night?” Following the fragrance to find the source, he suddenly discovered that it came from There was a small bottle of essential oil attached to the backlog of cases. When I opened the file, it turned out to be a gas poisoning case involving Xizhi’s mother and daughter.

“Why haven’t the cause of death certificates from the autopsy report been given to the family? Didn’t the forensic doctor determine that the possibility of homicide was very high?” Lin Hongsong was shocked when he read the file carefully, because apart from the transcripts of the parties involved, there was almost nothing in the file. It may be that the prosecutors, police and police who handled the case initially believed that the murder scene smelled of gas and the door was locked. They initially concluded that the mother and daughter committed suicide by turning on the gas, so the case was dropped. Unexpectedly, the murder case of a mother and daughter that had been almost forgotten by the prosecutors turned out to be the key to restarting the investigation because of the smell of perfume!

The prosecutor’s investigation revealed that Zhang Heling, 58, was originally a kitchenware master. He married Cai Tingyou in 1993 and had two daughters. They lived in a community building in Xizhi, New Taipei City. Zhang Heling and Su Yuzhen, a resident of the same community, were poker friends. Su’s husband was The air duct master and Zhang were work partners, and both families were familiar with each other. Cai Tingyou and Su Yuzhen became good sisters. Zhang Heling often played mahjong with Su Yuzhen. In October 2004, they had an extramarital affair. As a result, the relationship between Zhang Heling and Cai Tingyou changed. There were frequent quarrels. Zhang Heling moved out of his residence in January 2005 and rented a house by himself.

Angry Cai Tingyou once called Mr. Su Yuzhen and asked him to take care of his wife. Su Yuzhen denied the affair to her husband, but she held a grudge against Cai Tingyou. She once spray-painted Cai’s motorcycle to vent her anger. Once Su Yuzhen and Zhang Heling were in the car, they actually tried to hit Cai Tingyou with their car. The heartbroken Cai filed for divorce in January 2006. , but the two parties could not agree on the custody of their two daughters. Unexpectedly, on April 11, 2006, Cai Tingyou and her two daughters were murdered by gas poisoning.

The prosecutors were initially confused by the false appearance of gas poisoning created by Su and Zhang, and the case was stalled for a year and a half. Just when Su and Zhang thought everything was fine, Lin Hongsong, the then prosecutor of the Shilin District Prosecutor’s Office, relied on a wisp of essential oil scent to , just fished this case out of the “vast sea of ​​​​volumes”, and worked with Chen Jiongxu, the leader of the fourth investigation team of the Criminal Bureau (now the deputy director of the Criminal Bureau), and Li Yangji, the deputy team leader (now the second investigation team of the Criminal Bureau) Captain) and other operators worked tirelessly to find out the truth. It was discovered that Su Yuzhen was dissatisfied with Cai Tingyou’s frequent troubles with her, and believed that Zhang Heling’s marriage relationship could not be resolved in the short term. In March 2006, she asked Zhang Heling to kill his wife, otherwise the two would not be able to have a smooth relationship. Zhang Heling actually agreed.

Su Yuzhen and Zhang Heling began to develop a secret room murder plan, but Zhang was reluctant to start. Su’s daughter criticized him for breaking up without dealing with it. Zhang then sneaked onto the roof of his wife and daughter’s community building at 1 a.m. on April 11, 2006. , then put on headphones and called Su Yuzhen, saying that he would start executing the plan to kill his wife. Then he used the Scout rope ladder to descend to the steel clothes drying rack on Cai Tingyou’s balcony, climbed up and jumped into the balcony, and then opened the unlocked balcony door. Go indoors. After Zhang Heling discovered that his wife and daughter were all asleep, he first stupefied Cai Tingyou with ether and then suffocated her to death. At this time, her eldest daughter just got up to go to the toilet. Zhang was worried that his deeds would be exposed, so he suffocated his two daughters to death, and then turned on the gas to make it impossible to boil water. Beware of the false appearance of gas poisoning, he finally climbed back to the roof and left via the original route.

After the Supreme Court convened, it sentenced Zhang Heling to life imprisonment for killing his wife and daughter. This caused a backlash from the prosecutors and police. (Photo / Newspaper photo)

After the truth came out, Su and Zhang were brought to justice. However, Zhang Heling has been in prison for more than 15 years since he was taken into custody in June 2008, which meets the parole threshold of 15 years in prison under the old Criminal Law. After the news came out, The prosecutors and police officers all felt unfair. Lin Hongsong criticized, “What is fairness and justice?” He angrily accused Zhang Heling of ruthlessly killing his wife and daughter. The court did not impose the death penalty. Now he is about to be paroled. “I may go out to eat a bowl of noodles in the future, and he will sit next to me! “

It is understood that there are two key factors in Zhang Heling’s commute to life imprisonment in this case. The first is that Zhang Heling committed the crime of killing his wife, and was first sentenced to life imprisonment by the Supreme Court. As for the murder of his two daughters, he was sentenced to death by 15 judges of the first and second instance, because The Supreme Court was still hesitant to rule. The High Court in the fifth instance considered that he could be rehabilitated and commuted the sentence to life imprisonment. Only then did the Supreme Court support it. Zhang Heling managed to escape death by killing three people in a row, including his wife and daughter.
