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

"Tell me about it. ”

"Forensic doctor Wu said that the time of death of the deceased was between 1:30 and 4 o'clock in the afternoon. Li Hui took out his mobile phone and flipped through a few pictures:

During this period, Zhang Zihan also posted a WeChat circle of friends, the first one was uploaded at two o'clock in the afternoon, it was a selfie of picking up garbage; the second one was sent at three o'clock in the afternoon, Zhang Zihan stood next to two piles of garbage, one is renewable garbage, one is non-renewable garbage, all of which have been classified; The third picture was sent at three o'clock in the afternoon, she took a selfie standing next to two garbage bags, it should have just been put into the bag, these photos are very natural, not like being coerced. ”

"Assuming that these three moments of friends were posted by Zhang Zihan himself, it proves that she is not dead at 3:10 p.m., and the time of her death should be between 3:10 p.m. and 4 p.m. Li Hui analyzed.

"Could it be a photo taken in advance, 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 looked at the photos uploaded by Zhang Zihan and recalled: "I have seen the background of the photo, it should be a selfie taken at the first scene, and I did see the deceased's belongings there, every picture is a selfie of the deceased, and it is unlikely that the picture is fake." ”

"I think the same way, if you look closely, the content of these three pictures is also different, the first picture is just picking up garbage, the second picture is sorting two piles of garbage, the workload of this garbage picking up is real, if a person picks up these garbage, it will take at least 40 minutes to an hour, and the third picture is putting two piles of garbage into a garbage bag, it also takes about ten minutes to get it right. ”

Li Hui said this, moistened his throat, and continued: "In other words, it takes at least 50 to 70 minutes from picking up garbage, sorting garbage, and then putting garbage into bags. ”

Zhao Ming's words were stubborn: "On the afternoon of the 9th, Zhang Zihan's first picture of picking up garbage was sent at 10:00 a.m., and the third picture was posted at 10:10 a.m., with an interval of nearly an hour, which is completely consistent with Brother Hui's analysis. ”

Han Bin looked at the picture carefully, and he also agreed with Li Hui's analysis, from picking up garbage to bagging garbage, if it is a person, it does take at least an hour, but Han Bin thought of another possibility:

"If someone helped Zhang Zihan pick up the garbage at that time, the time to pick up the garbage would be shortened, and then he would have taken a selfie, and after the murderer killed Zhang Zihan, he would upload it according to the time when a person picked up the garbage. ”

"I don't think it's very likely, Zhang Zihan doesn't have an assistant, who will help her do this kind of thing. Li Hui said.

"Murderer. Han Bin said.

Li Hui gasped and continued to analyze: "Now it is certain that the upload time of the first circle of friends should be unnecessary. ”

"Even if the murderer helps pick up the garbage, the time is cut in half, and it will take half an hour. Li Hui said.

"And what if the murderers are two people?"

Li Hui sighed: "Twenty minutes." ”

Zhao Ming showed a wry smile, the more the situation was analyzed and complicated, and his brain was not enough: "If the number of murderers exceeds two people, won'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 two people, if three people helped her pick up the garbage, it would become two groups; if these two groups of people usually have a bad relationship with Zhang Zihan, Zhang Zihan will not let them help pick up the garbage; if they all have a good relationship with Zhang Zihan, it is impossible to fight back together, so I don't think there will be more than three people picking up garbage." ”

In other words, the time of Zhang Zihan's death can be accurate to between half past two and four o'clock. Li Hui analyzed.

In other words, anyone who leaves the park after half past two is suspicious. Sun Xiaopeng said.

"No, after killing Zhang Zihan, the body will be dragged and the body will be dug and buried, based on the situation at the scene and my experience, it will take at least an hour, if you add this time, the murderer should have left the park after half past three. Han Bin said.

In other words, anyone who leaves the park before half past three can be ruled out of suspicion for the time being. Zhao Ming said.

"From the analysis of the current evidence, this is indeed the case. Han Bin replied.

"The next time I make a record, I'll know it in my heart. Li Hui muttered.

......

"Knock knock......" Just then, there was a knock on the door outside.

"Come in. Han Bin said.

The door to the "squeaky ......" office was pushed open, and a man in his mid-thirties walked in.

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

"What's the matter with you?"

"My name is Wu Jianglong, and I am the anchor of Flying Fish, and I am here to make notes. ”

Han Bin had an impression of the name, and pointed to the chair next to him: "Sit down." ”

"Comrade policeman, if you have anything you want to ask, just ask, I will participate in an event in a while. Wu Jianglong glanced at his watch.

"You're a good time-saver. ”

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

"You usually live broadcast and talk like that?" 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 on the side: "This Wu Jianglong is the anchor of Successology. ”

Han Bin smiled: "How old are you?"

"26 years old. ”

"I'm in a hurry. ”

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

"You can successfully learn that set and put it away, and I will answer whatever I ask. Han Bin said lightly.

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

"What is the relationship between you and Zhang Zihan?" Han Bin said straight to the point.

"Colleague relationships. ”

"When was the last time you saw her?"

"It was the day of the 9th, at the gate of the botanical garden, we were making a car, and we had a good conversation, and she asked me for some investment advice. After Wu Jianglong finished speaking, he asked rhetorically:

"Comrade policeman, is there any problem? Something happened to Zhang Zihan. ”

"Zhang Zihan is dead. Han Bin said.

"It's dead!" Wu Jianglong's eyes widened.

"He, do you go to the botanical garden to promote environmental protection?" Han Bin asked.

"That's right. ”

"At that time, was there anything abnormal 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: "It's more than two o'clock in the afternoon. ”

"When?"

"I can't remember. ”

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

"Straight home. ”

"What time did you get home?"

"It's past three o'clock in the afternoon. ”

"Where do you live?"

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

Han Bin took out a map of the botanical garden: "Tell me, where are you cleaning the garbage?"

Wu Jianglong stared at the map for a long time, and pointed to the vicinity of a pine leaf forest: "It should be this one." ”

"Did you hear any unusual sounds while you were cleaning up the garbage?" asked Han Bin.

"Nope. Wu Jianglong replied 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 half past three, if Wu Jianglong left after two o'clock, then he didn't have time to commit the crime at all." ”

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

"Brought back. Tian Li replied.

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