It turned out that Kim Tae-hyun decided and prepared the crime a week before the murder.
The Seoul Nowon Police Department announced the results of the investigation on Kim Tae-hyun at 10 am today (9th).
The police said that Kim Tae-hyun had decided and planned the crime a week before the 23rd of last month when Kim Tae-hyun murdered her three mothers and daughters.

The police confirmed that Kim Tae-hyun met his eldest daughter three times from January this year.
Among these, the last meeting revealed that Kim Tae-hyun found out the addresses of the three mothers and daughters, and then went to the front of the house and met the eldest daughter.
Kim Tae-hyun said that during a police investigation, she was angry that her eldest daughter lost contact and did not meet her, and that she decided to commit the crime.
