A man in his 30s who was arrested after killing a taxi driver and hiding the body in a closet confessed to killing his ex-girlfriend in August.
Neighbors' testimony about both the killer and his ex-girlfriend is drawing attention.
The man lived in an apartment owned by his ex-girlfriend whom he claimed to have murdered for more than four months after the crime.
Some residents remembered that the man and his deceased girlfriend did not get along, sometimes fighting violently.
A neighbor said that he reported to the management office several times and went to visit, but one day, the sound of arguing disappeared and the man started walking alone.
Another neighbor said the two of them had often been seen going out before, but since this fall, he has rarely seen anyone except a man enter the house.
Police searched the river for the man's body, but have yet to find it.
