Invested 500 million yen in lover but didn't get the return, killed mother... 35 years in prison (Korea)

A South Korean man who invested a huge sum in his girlfriend's business and then murdered her mother out of spite when she refused to return his money has been sentenced to 35 years in prison.
According to the legal community on the 26th, the Supreme Court's second division decided to impose the following sentence on a man indicted on suspicion of murder, attempted murder, and special trespass.
The original ruling was finalized on the 27th of last month. A stabbed his girlfriend's mother, B, multiple times with a deadly weapon at around 1:57 pm on July 21, 2023, in an apartment in Bucheon City, Gyeonggi Province, killing her.
Prior to the crime, he is also suspected of wandering around the apartment area twice with a weapon in order to kill Mr. B and his daughter, Ms. C.
In September 2021, A met C through a dating app and lent him a total of 90 million won over several times until November of the same year.
After their relationship developed, he invested about 400 million won in C's real estate agency business, on the condition that he would receive 60% of the profits until the summer of 2022.
A was in a difficult financial situation and raised money from his acquaintances to invest in C. However, C
Although A said that he had earned 2.5 billion won, he did not give the money to A as promised. In January 2023, A called his girlfriend's mother, B, and demanded repayment. B asked, "Why did C give you money?
"Why should I give you money? Don't make C suffer." In May of the same year, C told A, "My mother took my mobile phone and I can't send money."
A thus developed a grudge against both B and C. Eventually, A began to suspect that C was using the investment money for other purposes. A filed a lawsuit against C.
A went to their house to kill them, but turned back at the front door. He demanded the profits from the crime, saying he would give them one last chance.
However, the next day, Ms. C called and said, "I will not maintain the relationship." In response, A waited in front of Ms. C's house with a weapon, but when Ms. B opened the front door, A entered the house and
A stabbed Mr. B with a weapon, and Mr. B died on the spot. A searched the house to kill Mr. C, but Mr. C was not at home.
Immediately after the crime, A called the police and turned himself in, admitting that he was the perpetrator.
The first and second instance courts sentenced A to 35 years in prison. The Supreme Court dismissed the appeal, stating that "it cannot be said that the decision to uphold the 35-year sentence was extremely unjust."
