Zhang Wei's question raised doubts in everyone's minds for the first time.
Could the murderer be someone other than Tang Chunfeng?
This turn of events was unexpected for Wang Can, Xiao Baihe, and others.
Doubts arose amongst the jurors, the attendees, and even some of the judicial personnel at the scene were skeptical.
Zhang Wei introduced the concept of DNA transfer.
Could Tang Chunfeng have left behind residual skin tissue at the scene because of DNA transfer?
Once this question was raised, those naturally inclined to skepticism found it hard to dismiss the thought.
It was just like Zhang Wei had demonstrated earlier: he held hands with Xiao Baihe, who then shook hands with Tan Yingying.
But Zhang Wei had never touched Tan Yingying, yet his DNA would be found on her hand!
The jurors were full of doubt, their suspicious glances turning towards Wang Can and Doctor Peng on the witness stand.
"That concludes my cross-examination of this witness!"
