When the case was reported, the capital Governor immediately asked Constable Gao to bring the Coronet and Yamen runners over.
Constable Gao and his men went to ask around, but they didn't find anything suspicious. The whole village said that they had seen their family yesterday, but they didn't see anyone today.
They didn't have any guests.
The coroner also examined the family and found that they had been poisoned. All the women had their hair cut and died from several cuts.
The family's bodies were not in the same room, but in their own rooms. There was no trace of a dispute at the scene.
However, according to the information from Constable Gao, the door and the kitchen of this family were all locked from the inside, and so were the windows. How did the murderer escape?
