"But these can provide us with some information." Lin Yi said.
"Firstly, this accomplice knows both Song Deyuan and Zhang Hao."
"Secondly, when Du Juan died, Zhang Hao went to Aomen. In that case, the murder in the secret room must have been set up by that accomplice."
"Thirdly, we've already checked Du Juan's house. There are no signs of forced entry. This means that the other party might have used a key to enter…"
With that, Lin Yi's gaze swept across the four of them one by one and continued.
"That murderer might have a very good relationship with Du Juan!"
The four of them fell into deep thought. Soon, Li Xianghui, Zhang Hui, and Gao Mingjun looked at Gu Yiran.
Because the people around Du Juan were brought back by her and Lin Yi for interrogation, the two of them knew this better than anyone else.
Gu Yiran was also thinking hard. Then, she understood and looked at Lin Yi!
"Du Juan's cousin, Wang Jia!"
