DA: Gwinnett man tied ex-girlfriend up, sexually assaulted her

A 22-year-old Gwinnett County man has been sentenced to 25 years in prison for sexually assaulting his ex-girlfriend, the district attorney’s office said.

David Hyun Kang was convicted of aggravated sexual battery, aggravated assault, false imprisonment and simple battery. The jury returned a guilty verdict on all charges after a four-day trial.

It’s now been 10 year since Gwinnett teen Justin Gaines disappeared

In September 2016, Kang’s ex-girlfriend went to his house to collect some belongings she had left there and have Kang repay her some money. Kang, who lived with his parents, arranged for his parents to be out of the house when the woman arrived, the district attorney’s office said.

Kang had told his ex-girlfriend that all of her belongings would be downstairs and that he would repay money he owed her. When she got there, some of her things were upstairs and he did not have the money, the district attorney’s office said.

Kang told her the money was upstairs. When they went upstairs, Kang choked the woman, threw her to the ground and tied her hands and feet “to keep her from leaving,” the DA’s office said. He then sexually assaulted her and told her he wanted her to watch him kill himself. He cut himself with a box cutter and took multiple Adderall pills, the DA’s office said. He then untied the woman and she ran out of the house.

In an interview with police, Kang said he “just snapped.” 

In addition to 25 years in prison, Kang must spend the rest of his life on probation and register as a sex offender once he is released.
