It was 6 am in the morning, Chun with her students crowded the living room as they were solving a piece of puzzle. They discovered that the killings had a pattern to it. The culprit only killed family members that were ranging from twenty to forty-eight. Comparing the cases of deaths, the killer had a motive of destroying the Yu household slowly and painfully by making them suffer from losing their capable family members.
The silver haired young man felt that her judgement about the culprit having a group of accomplices was wrong. Her instincts were telling him that this murder plot was instigated by only one person. Based on the deaths, the culprit deliberately left a clue which didn't make sense. As Lerrent and Chun examined those clues, it wasn't from the victims as they were written by the culprit using the victim's blood. Why would 'they' purposely left a clue for their crimes?
It truly didn't make sense.
