19-year-old bride dies on the first day of her honeymoon... The details of the ”honeymoon murder” in South Korea

On August 30, 2018, in South Korea, a man in his 20s who was indicted on suspicion of killing his wife by injecting her with undiluted nicotine during their honeymoon was sentenced to life imprisonment.
In September 2015, A (then 19 years old) met B (then 17 years old), who was working part-time at a restaurant run by her parents, and the relationship developed into a romantic relationship.
Despite their parents' opposition, the couple filed for marriage registration as soon as Mr. B became an adult and went on a honeymoon to Osaka.
However, their honeymoon ended at dawn on the day they arrived in Japan.
Mr. B lost consciousness in the bathroom, collapsed and died. Mr. A quickly notified the local police, saying, "It seems that my wife collapsed and died in the bathroom."
Police who responded to the call found Mr. B dead in the toilet. There were traces of use nearby.
A syringe and a bottle containing nicotine concentrate were found. A told the police, "My wife, who suffered from depression, drank a lot of alcohol and committed suicide."
At that time, the Japanese police, with the consent of the family, performed an autopsy on Mr. B's body and found that he had died of acute nicotine poisoning.
The police concluded that B committed suicide and closed the investigation. After that, A cremated his wife's body in Japan, held a funeral, and returned to Korea.
On May 4, 2017, 10 days after his wife's death, A called an insurance company and said that his wife had died of depression during their honeymoon.
Before going on their honeymoon, A had his wife sign up for travel insurance and made himself the beneficiary of the insurance.
When the insurance company said that they could not pay out the insurance money in the case of suicide, A sighed and looked disappointed.
An insurance company employee intuitively sensed something was wrong and provided information to the police, which led to an investigation.
The police, who had begun their investigation, discovered a diary in A's house.
Along with the nicotine murder plan, the motive for the crime, such as "Saving 1 billion yen before I turn 40," was written. The police who investigated A found that on December 20, 2016, four months before the incident, A had been in a relationship with another woman.
It was discovered that he had traveled to Japan and attempted to kill a woman using the same method. However, this evidence was insufficient to prove murder, and the police requested the Japanese police to obtain an autopsy report.
According to the forensic examination report, three injection marks were found on the arm of the deceased Mr. B. Nicotine and alcohol were detected in his stomach, but no alcohol was detected in his blood.
At the time of the incident, A claimed that his wife had committed suicide after drinking too much, but no alcohol was detected in the blood of the deceased B. This was because B had not absorbed the alcohol.
This means that he died before he could be killed. After consulting with experts, police said that nicotine is a highly potent toxic substance and the toxicity spreads quickly after a single injection, and that the victim had self-injected in three places in his arm.
The police also found that it was impossible to inject nicotine into his wife. The police questioned A and extracted a statement from him that he had injected nicotine into his wife. However, A said, "My wife said she wanted to commit suicide, so I gave her the nicotine injections.
A denied the allegations, saying, "I only helped her, I did not kill her." A was subsequently put on trial for murder and other charges, and was sentenced to life imprisonment in the first instance. At the time, A appealed, claiming to be mentally and physically weak.
In the appeal hearing, the court stated, "The defendant made careful preparations to kill his wife on the pretext of their honeymoon," and "His wife must have suffered from nicotine poisoning just before she died, but the defendant has denied the crime."
The court upheld the original ruling, stating that A has not shown any remorse for his actions. The case ultimately went all the way to the Supreme Court, which dismissed A's appeal and finalized his life sentence.
