[Asia Economy Reporter Lee Jung-yoon] Kang Yoon-sung (56), who was arrested for damaging an electronic tracking device (electronic anklet) and murdering two women. Investigations revealed that he committed the crimes with the intent of obtaining money from the victims. It was also found that he had a strong obsession with money and a desire for control.

According to the legal community on the 26th, the Criminal Division 3 of the Seoul Eastern District Prosecutors' Office (Chief Prosecutor Lee Gon-ho) has indicted Kang on charges including robbery-murder, murder, fraud, obstruction of official duties, violation of the Specialized Credit Finance Business Act, violation of the Telecommunications Business Act, and violation of the Act on Electronic Monitoring Devices.

Kang, a 14-time offender, had no particular job after being released from prison in May but pretended to be wealthy to those around him, borrowing money or taking out loans from banks to cover entertainment expenses. When he found himself in financial difficulties, he planned the crimes for money.

On the 26th of last month, Kang lured victim A to his home and asked to borrow money, but when refused, he killed her. Afterwards, using A’s credit card, he bought four mobile phones worth approximately 5.96 million won at a mobile phone store in Gangnam-gu around 11:30 a.m. on the 27th, then resold them.

Additionally, before the first crime, around July 27, Kang defrauded approximately 3 million won by opening mobile phone contracts without the intention to pay for the devices or actually use the phones, then disposing of them?a method commonly known as 'phone kkang' (휴대폰 깡).

On the 29th of last month at around 3:30 a.m., Kang met the second victim, B, and when she pressed him to repay a debt, he killed her in her vehicle.

The prosecution judged Kang to be a psychopath. According to the integrated psychological analysis by the Supreme Prosecutors' Office, Kang exhibited pervasive feelings of victimization and anger toward laws and social systems, with a strong desire to manipulate victims as means for sexual and economic exploitation. It was also confirmed that he lacked awareness of the problems in profiting from criminal acts and had an excessive obsession and desire for control over money.

Meanwhile, Kang is charged with killing a woman in her 40s, A, at his home around 9:30 p.m. on the 26th, cutting off his electronic anklet and fleeing the next afternoon, and killing a woman in her 50s, B, in a vehicle around 3:30 a.m. on the 29th. However, the prosecution dismissed the charge of attempted murder against Kang, stating that no hostile relationship with the victims was confirmed and that Kang appeared to have made false or exaggerated statements.
