The victim in the case in which a body was found in a suitcase in Daegu's Sincheon was a woman in her 50s who died after being assaulted by her son-in-law while living together in a small home to protect her daughter from domestic violence.
Police said on the 3rd that the suspect in the suitcase case was found to have been living together to protect daughter A, who was subjected to domestic violence by son-in-law B.
The victim moved into an officetel-style studio in Jung District, Daegu, with the couple in Feb., when it began. After B, the son-in-law, began living with the victim, he assaulted her on the grounds that she was not unpacking quickly, and it was found that the victim continued living in the studio despite daughter A's request to live separately.
In a police interview, B said, "I committed the crime because my mother-in-law was usually noisy and did not put things away."
After B assaulted the victim and she died, he put the body in a suitcase and, together with A, abandoned it in Daegu's Sincheon. Police reportedly captured their movements and secured evidence.
B was also found to have restricted A's daily life to conceal the crime. Instructing her not to report the crime to police and others, B continued surveillance by always accompanying her even when going out for about two weeks until the body was found.
Police are conducting additional investigations into Cho's domestic violence.
On the 31st, police received a report that a suitcase was floating in Sincheon in Chilseong-dong, Buk District, and launched an investigation. Through the probe, the two were arrested on the same day, and the couple was detained on charges of parricide and abandoning a body, while Choi was detained on a charge of abandoning a body.
