At 4 p.m., In the office of the Kunyang police station.
Wu Xiumin was explaining her psychological profile of the murderer to Zhao Yu.
"The murderer clearly had a tendency for revenge. I noticed the rise and fall of his chest and the trembling of his shoulders. All of these showed that he was very agitated at the time ...
"Don't look at how he deliberately raised a finger in front of the camera. In fact, he's panicking.
"Also, I carefully observed the trajectory of his axe. The axe was held very professionally, and all the slashes were almost vertical, indicating that he had experience with using an axe.
"But, the places where he slashed were obviously a little messy. I feel that he didn't do it on purpose, and he didn't want the deceased to suffer for a long time.
"Also, after cutting him down, we could clearly see that he was panting because of his nervousness. It was just that we couldn't feel it very clearly through the daunting mask.
