An hour later, Kim is spotted using the stairways to exit the apartment. 

It's revealed that Kim made the visit to his girlfriend's home to attack B, who disapproved of their relationship and demanded her daughter to break up with Kim. The frightening incident in B's apartment was reported to the police by a neighbor who heard shrieks and spotted blood on the stairway. It's reported Kim's girlfriend was also at the scene at the time, however, failed to take any action due to shock. 

A day earlier on October 24, Kim was also reported to the police by a passerby who saw him slap his girlfriend's face in the streets. The dating violence is revealed to be the reason why B opposed her daughter's relationship with Kim. 

Currently, the investigation with Kim is ongoing at Daejeon Yuseong Police Station.
