The recent Incheon shooting incident has taken a chilling turn as emerging evidence suggests that the 63-year-old perpetrator, identified as Mr. A, had a deeply personal motive: to destroy the happiness of his ex-wife, the CEO of the renowned beauty brand Yakson Beauty.

According to an investigation by The Fact, Mr. A divorced his wife two decades ago due to his own misconduct. His former spouse went on to become a hugely successful entrepreneur, building Yakson Beauty into a powerhouse in cosmetic therapy, with over 130 branches in South Korea and a growing presence in seven overseas countries, including Taiwan, Japan, Singapore, and Vietnam.

In a past interview, the Yakson Beauty CEO had expressed her devotion to her son, saying, “If someone asks why I live, I live so that my son can be happy. As a mother, I want only the best for him.”

Tragically, her son, a man in his 30s who co-managed the beauty brand with her, was brutally killed by his father during a birthday celebration at a luxury penthouse in Incheon on July 20. The crime occurred in front of his wife and children, turning a moment of familial joy into a nightmare.

Mr. A later claimed that “domestic conflict” was his reason for the murder. However, criminal experts argue that the killing was likely driven by twisted possessiveness and a desire to take away what his ex-wife valued most: her son.

Evidence supports this theory. After the murder, Mr. A was apprehended while en route to Seoul’s Gangnam district. At the time of arrest, he had set up an elaborate arson plan targeting his ex-wife’s apartment in Dobong-gu. Police found 15 containers of flammable substances and an ignition timer scheduled to trigger at noon that same day—suggesting a premeditated attempt to destroy her property.

In addition to the two homemade firearms used in the murder, police discovered 11 additional gun barrels and several metal pipes in his vehicle and residence. Mr. A reportedly admitted to learning how to build firearms through YouTube and claimed he had stored the ammunition for over 20 years.

The horrifying events continue to unfold, painting a disturbing picture of revenge fueled by resentment and a deeply fractured family dynamic. The case underscores the need for vigilance in recognizing signs of possessive behavior and highlights the devastating consequences of unresolved familial conflict.
