His girlfriend died after penetrating the weapon... "Putting yourself in the chest."

JTBC's press screen.

While it was belatedly known that a woman in her 20s was stabbed to death in a room where she was alone with her boyfriend, the boyfriend denies the crime, saying, "My girlfriend killed herself."

According to a JTBC report on the 11th, a woman in her 20s was stabbed to death at her boyfriend, Kim's house in August. Lim and Kim were alone at the scene of the incident.

Boyfriend Kim reported to 119 and said, "When I tried to stab me with a weapon and avoided it, my girlfriend stabbed herself in the chest." He also denied the crime, rambling to the bereaved family asking about the situation.

Later, Kim posted on social media (SNS), "I loved you every moment no matter what anyone says," "Please don't look for me for a while," and "I will explain everything and follow you." He also posted, "It's cowardly to follow him now."

An autopsy revealed that Lim's body was so strong that the weapon penetrated the heart.

The bereaved family said, "I am 155 centimeters tall. It is not easy for a woman (who is slender) to penetrate the heart on her own."

The investigative agency found that Lim had a verbal argument with Kim just before he died, and that Lim had a quarrel with another man on the phone. In addition, two weeks after the two met on Lim's mobile phone, Lim also confirmed a record of him asking Kim to break up.

Police arrested Kim for murder a month after the incident, but Kim still insists on his innocence.

The bereaved family said, "The friendship murder can happen to anyone," adding, "I hope the court will deal with it seriously."
