Three Hundred and Twelve Wujiang Dragon

"Binzi, I think the time of death can be more precise," Li Hui said.

"Tell me."

"Forensic Doctor Wu said the time of death of the deceased was between 1:30 and 4:00 in the afternoon." Li Hui took out his mobile phone and opened several pictures:

"During this period, Zhang Zihan also posted to WeChat Moments. The first one was uploaded at 2:10 p.m., which was a selfie of picking up garbage; the second one was posted at 3 p.m., with Zhang Zihan standing on the Next to the two piles of garbage, one is recyclable garbage and the other is non-renewable garbage, both of which have been sorted. The third picture was posted at 3:10 in the afternoon. It is a selfie of her standing next to two garbage bags. It should be They just put the garbage into the bag. These photos are very natural and don't look like they were coerced."

"Assuming that Zhang Zihan posted these three Moments herself, it proves that she is not dead yet at 3:10, and her death time should be between 3:10 and 4:00 in the afternoon." Li Hui analyzed.

"Could it be that the photos were taken in advance and uploaded by the suspect after the deceased was killed in order to change the time of the killing and create an alibi." Tian Li questioned.

Han Bin had seen the photos uploaded by Zhang Zihan and recalled: "I have seen the background of the photos. They should be selfies taken at the first scene. I did see the deceased's belongings there. Every picture is a selfie of the deceased. , it is unlikely that the picture is fake.”

"I think so too. If you take a closer look, the contents of these three pictures are also different. The first picture shows just picking up garbage; the second picture shows two piles of garbage being sorted. The workload of picking up garbage is To be honest, if one person picks up this garbage, it will take at least forty minutes to an hour; the third picture shows two piles of garbage put into garbage bags, which also takes about ten minutes to complete."

Li Hui said this, moistened his throat and continued: "In other words, from picking up garbage to sorting the garbage and then putting the garbage into bags, it will take at least fifty to seventy minutes. between."

Zhao Ming finally said: "On the afternoon of the 9th, Zhang Zihan posted the first picture of picking up garbage at 2:10; the third picture was posted at 3:10, with nearly an hour in between. It is completely consistent with Brother Hui's analysis. Match."

Han Bin looked at the picture carefully again. He also agreed with Li Hui's analysis. From picking up garbage to bagging it, it would indeed take at least an hour by one person. However, Han Bin thought of another way. possible:

"If someone had helped Zhang Zihan pick up trash at that time, the time it took him to pick up trash would have been shortened, and then he would have taken a selfie. After the murderer killed Zhang Zihan, he would have uploaded it according to the time it took for one person to pick up trash."

"I think this possibility is unlikely.

Zhang Zihan doesn't have an assistant, who would help her do this kind of thing. "Li Hui said.

"The murderer." Han Bin said.

Li Hui took a breath and continued his analysis: "What is certain now is the upload time of the first Moments. There should be no need to falsify it."

"Even if a murderer helps to pick up trash, the time is reduced to half, that's still half an hour." Li Hui said.

"What if the murderer is two people?"

Li Hui sighed: "Twenty minutes."

Zhao Ming showed a wry smile. The more he analyzed the situation and became more complicated, his brain was running out: "If there are more than two murderers, wouldn't this time be shortened?"

Han Bin thought for a moment: "It's unlikely. The colleagues who went with Zhang Zihan either acted alone or with two people. If three people helped her pick up trash, it would become two groups; if the two groups usually If they all have a bad relationship with Zhang Zihan, Zhang Zihan won't let them help pick up trash; if they all have a good relationship with Zhang Zihan, they won't be able to rebel together, so I don't think there will be more than three people picking up trash."

"In other words, Zhang Zihan's death time can be accurate to between two-thirty and four o'clock." Li Hui analyzed.

"In other words, anyone who leaves the park after 2:30 is suspected." Sun Xiaopeng said.

"No, after killing Zhang Zihan, you still have to drag the body, dig a hole and bury it. Based on the situation at the scene and my experience, it will take at least an hour. If this time is added, the murderer should be after 3:30. Leaving the park," Han Bin said.

"In other words, anyone who left the park before 3:30 can be ruled out of suspicion for the time being." Zhao Ming said.

"Based on the current evidence analysis, this is indeed the case." Han Bin replied.

"Next time I take notes, I'll know better." Li Hui muttered.

…

"Dong dong..." At this moment, there was a knock on the door outside.

"Come in." Han Bin said.

"Creak..." The office door was pushed open, and a man in his thirties walked in.

The man had a mustache, gold-rimmed glasses, and a briefcase in his hand.

"What's your business?"

"My name is Wu Jianglong, I am the anchor of Feiyu Company, and I am here to take notes."

Han Bin was impressed by the name and pointed to the chair next to him: "Sit down."

"Comrade police, if you have anything you want to ask, please ask immediately. I have to attend an event later." Wu Jianglong glanced at his watch.

"You are quite good at saving time."

"Time is like a sponge. As long as you squeeze it, there will always be some." Wu Jianglong said.

"You usually talk like this during live broadcasts?" Han Bin said with a smile.

"During the live broadcast, I mainly share my business experience and life insights with my fans to help them solve some difficulties in work and life."

Li Hui reminded from the side: "This Wu Jianglong is the anchor of Chenggong School."

Han Bin smiled: "How old are you?"

"26 years old."

"You look quite anxious."

Wu Jianglong pushed up his glasses and touched his moustache: "Some fans are young, and they always like to judge people by their appearance, so I dress a little more mature, you know."

"If you successfully learn that trick, put it away. Just answer whatever I ask." Han Bin said calmly.

He really couldn't imagine how much business experience a 26-year-old person could have and how much life insights he could have.

"What's your relationship with Zhang Zihan?" Han Bin said straight to the point.

"Colleagues."

"When was the last time you saw her?"

"On the 9th, at the gate of the Botanical Garden, we were building a car, and we got along quite well. She asked me for some investment advice." After Wu Jianglong finished speaking, he asked:

"Comrade police, is there any problem? What happened to Zhang Zihan?"

"Zhang Zihan is dead." Han Bin said.

"Dead!" Wu Jianglong's eyes widened.

"Do you also go to the botanical garden to promote environmental protection?" Han Bin asked.

"Yes."

"At that time, was there anything unusual about Zhang Zihan?"

Wu Jianglong shook his head: "I didn't see it."

"When did you leave the park?"

Wu Jianglong recalled for a moment: "About two o'clock in the afternoon."

"The specific time?"

"Can not remember."

"Where did you go after leaving the Botanical Garden?"

"Going straight home."

"What time did you get home?"

"About three o'clock in the afternoon."

"Where does your family live?"

"Sihui Home, Unit 1, Building 3, Room 702."

Han Bin took out a map of the botanical garden: "Point to where you cleaned the garbage?"

Wu Jianglong stared at the map for a while, then pointed to a pine leaf forest: "It should be this area."

"Did you hear any unusual noises while cleaning the garbage?" Han Bin asked.

"No." Wu Jianglong responded and looked at his watch again.

Han Bin asked for a while, but without asking any more information, he let Wu Jianglong leave first.

Li Hui closed the door of the office: "According to our speculation, the suspect left the botanical garden after 3:30. If Wu Jianglong left after 2:00, then he had no time to commit the crime at all."

Han Bin asked Tian Li on the side: "Have you brought back the surveillance cameras at the front and back doors of the Botanical Garden?"

"Bring it back." Tian Li replied.

"Check the surveillance to see if he left after two o'clock." Han Bin ordered.
