Police in Daegu have arrested a 24-year-old man who murdered the parents of his estranged girlfriend.
After fatally stabbing the couple, the culprit, identified only as Jang, drank liquor beside the bodies for hours waiting for his ex-girlfriend to come home.
The ex-girlfriend, Kwon, 20, who had been living with her parents, arrived at the house at midnight, about six hours after the killings.
Kim locked her in a room, but she jumped from the window of the fourth-floor apartment two hours later and managed to call the police.
Kwon was severely injured from the jump, but is not in a life-threatening condition, police said. Jang fled the scene after Kwon escaped but was caught at his home in Gyeongsan, North Gyeongsang Province, hours later.
It appears Jang had held a grudge against Kwon’s parents, who didn’t approve of Jang and talked their daughter into breaking up with him, police said.
