Chulsoo Jung jailed over murder of Epping woman Min Sook Moon

A man has been jailed over the murder of his mistress, after he strangled her with a phone charging cord in the front seat of his van.

A man who strangled his mistress with a phone charger in a “violent act of uncontrollable passion” has been jailed for at least 13 years and six months for her murder.

Fifty-six-year-old Chulsoo Jung killed his mistress Min Sook Moon on March 8 last year, strangling her with a phone charging cable as she sat in the front seat of his van.

Jung hid in the back seat when Ms Moon entered the vehicle to discuss their relationship, and killed her in an impulsive rage.

He faced the NSW Supreme Court on Friday, where Justice Ian Harrison sentenced him to 18 years jail, with a non-parole period of 13 years and six months.

“Mr Jung must be punished for his crime, he took the life of a woman who was both unsuspecting and undeserving of his brutality,” he said.

Min Sook Moon, aged 49.

The pair had been having an affair for three years at the time of Ms Moon’s death, first meeting nine years earlier at Ms Moon’s Korean grocery store in Epping.

Jung would deliver and sell Korean products to Ms Moon before they started an intimate affair which they both hid from their families.

After strangling Ms Moon for more than five and a half minutes, Jung disposed of her phone at a park, before a buying a shovel at Bunnings and returning home,

He left her body in his van overnight before burying her body under a tree at a Silverwater park, the court heard.

Her family reported her missing on March 10, and Jung initially lied to police about his involvement, telling them he last saw her in a carpark after an argument.

On March 19, he was found in his van at Silverwater by police, with a self-inflicted cut to his left wrist. He later told his wife he had murdered Ms Moon and asked her to take him to the police station, where he confessed to killing her.

Chulsoo Jung was sentenced in the NSW Supreme Court.

He told police he was angry with Ms Moon and that she kept asking him to divorce his wife, threatening to tell his family if they did not.

However, the court heard this claim was disputed, and Justice Harrison gave it little weight, saying he was “cynical” about the allegation.

In his interview with police, Jung said the murder was “impulsive” and“ without me realising I just felt the urge to kill her”.

The court heard that while the crime was serious, Jung was unlikely to reoffend and was remorseful for his actions.

He sat emotionless in a jail cell as his sentence was handed down in the Supreme Court, occasionally looking down at his lap.

He will be eligible for release to parole in 2034.
