A tragic incident in Osan, South Korea, has left one person dead and several injured after a woman accidentally set her apartment building ablaze while attempting to kill a cockroach with a makeshift flamethrower. The woman, in her 20s, reportedly used a lighter and flammable spray to torch the insect, a method she claimed to have employed before. However, the fire quickly spread, igniting items in her home and engulfing the building in flames. One of her neighbors, a Chinese national in her 30s, died after falling from a window while trying to escape the thick smoke that blocked the stairway. The victim, who lived on the fifth floor with her husband and two-month-old baby, was pronounced dead hours after being rushed to the hospital. Her husband managed to escape by climbing to an adjacent building, and their baby was safely handed to a neighbor. Eight other residents suffered from smoke inhalation. Police are seeking an arrest warrant for the woman, who could face charges of accidental arson and negligence causing death. This incident highlights the dangers of using homemade flamethrowers, a method popularized by social media videos, to eliminate household pests. A similar incident occurred in Australia in 2018, where a man set his kitchen on fire while attempting to kill cockroaches with a DIY flamethrower.
