Chong Sun Wargny, 53, known also by her Korean name Kang Hee-jung, was the owner and operator of Happy Days Bar, a cafe in the Korea Town area of Dallas. She was working behind the bar on Royal Lane on the night of April 3, 2023 when an interaction over service escalated into lethal violence.

A 62-year-old man named Wan Cho entered just before 10 p.m., asked for a drink and — after being refused — exchanged insults with Wargny. He left, returned about 15 minutes later, pulled a gun and shot her multiple times in front of witnesses. Bystanders restrained Cho and detained him until Dallas police arrived; Wargny was taken to a hospital and died of her injuries. Cho was arrested at the scene and charged with murder and aggravated assault with a deadly weapon. Reports say the argument began over refusal of service and that Cho had a prior assault conviction after a similar incident in 2015.

Did anyone who knew Chong Sun Wargny or witnessed the incident come forward with information that could help explain what happened that night?
