Prosecutors sought a 1.5-year prison sentence for the mother of singer Jang Yoon-jeong, a woman in her 70s accused of defrauding an acquaintance of approximately 31 million won. The defendant admitted to the charges, claiming the funds were used for living expenses and credit card payments. Representatives for Jang Yoon-jeong stated the incident was unrelated to the singer, noting she has been estranged from her mother for over a decade.

On September 10, the Seoul Eastern District Court sentenced the defendant, identified as Yuk, to 10 months in prison. The court found that between September 2024 and August 2025, Yuk used her daughter’s name to convince victims that the singer was also profiting from the investments. While the defendant cited her advanced age and poor health as mitigating factors, the court noted the seriousness of the crime and the lack of compensation for victims. Yuk also has a prior 2018 criminal record for a 400 million won fraud case.
