China's famous detective Jiangnan: There are ghosts on campus

Chapter 92 Continue to investigate (4)

"Why are you so sure?" I asked her.

"It took about 15 minutes for us to rehearse one dance, and I think they left after we rehearsed twice."

I nodded. 
Da-da, da-da.

I immediately lowered my head and fell into thinking, hitting the table with my fingers from time to time.

Because Wang Tiancheng was discovered by the police shortly after his death, and the forensic doctor used the most advanced ocular chemical method. Because of the principle that the vitreous humor will continuously and regularly enter the eye, Wang Tiancheng's death time in the autopsy report is relatively accurate, it is 2:[-], and the error does not exceed [-] minutes.

The University Student Activity Center is located between the North District Campus and the South District Dormitory, relatively close to the South District Dormitory. It takes about 10 minutes for a normal person to walk from the University Student Activity Center to the forest near the North District Campus Gate.

If Zhang Yao's hands-on time is counted, then he will definitely leave the student activity center before [-]:[-] at the latest.

"Did any of the four boys on the way leave first?" I looked up and continued to ask.

"No." Wang Yuting thought for a while and said, "However, some people went to the toilet halfway, and then came back."

"Really?" I looked at her closely and said, "Do you remember who went to the bathroom?"

"They all seem to have gone." Wang Yuting said with some embarrassment: "Our rehearsal is facing the gate, and they all go to the bathroom together."

"Is that so?" I frowned.

"When you were rehearsing during this period, where did you put your mobile phone and other personal belongings?" I then asked.

"Put it on the audience chairs aside." Wang Yuting replied.

"Is the thing kept in your sight all the time? Or if someone else touches your thing, will you know?" I asked deeply.

"It's hard to say." Wang Yuting replied: "Sometimes if we don't pay attention to it, we naturally don't know."

So this gave Zhang Yao a chance to take Lin Huiqing's phone, I thought to myself.

From this point of view, this proves my conclusion in terms of time. Zhang Yao got Lin Huiqing's mobile phone at around [-]:[-], and it is very likely that he installed the mobile phone card in another mobile phone with the function of changing the voice and then dialed the phone number. Wang Tiancheng tricked him to the small forest near the north area of ​​the school. Zhang Yao left the student activity center at about [-]:[-], and met Zhang Yao and Wang Tiancheng at [-]:[-]. Then Zhang Yao killed Wang Tiancheng.

However, although the process of Zhang Yao's crime has been clarified, I still don't understand his motive for committing the crime and how to kill Wang Tiancheng.

I raised my head and looked at my phone. Before I knew it, nearly four or ten minutes had passed.

I glanced at Zhang Xiaoqi next to me, indicating that this conversation can be over, then got up and said to Wang Yuting: "Then let's leave this conversation as it is, thank you for your cooperation!"

"You're welcome." Wang Yuting also stood up and said, "But police officer, I believe that Lin Huiqing cannot be the murderer who killed Wang Tiancheng and Zhou Shengrong. She really has no reason or ability to do such a thing!"

I nodded and said, "The police will consider your suggestion."
