Detective from the Future

“Bin, I think the death time can be more precise.” Li Hui said.

“Tell me.”

“Examiner Wu said that the death of the deceased was between 4:XNUMX and XNUMX in the afternoon.” Li Hui took out his phone and opened a few pictures:

“And during this period, Zhang Zihan also sent a WeChat circle of friends. The first one was uploaded at 2:2 pm and was a selfie while picking up trash. The second one was from 3 pm and Zhang Zihan was standing Next to the 2 piles of garbage, one is renewable garbage and the other is non-renewable garbage, both have been categorized; the third picture is issued at 3:3 in the afternoon, and the selfie she was standing next to the two garbage bags should be Just put the garbage in the bag, these photos are natural and don’t seem to be coerced. ”

“Assuming that these three circles of friends were all sent by Zhang Zihan himself, it turns out that she was not dead at 3:3, and her time of death should be between 3:4 pm and XNUMX pm,” Li Hui analyzed.

“Will it be a good photo taken in advance and uploaded by the suspect after the deceased was killed in order to change the time of the killing and create a certificate of absence.” Tian Li questioned.

Han Bin saw the photo uploaded by Zhang Zihan and recalled: “I have seen the background of the photo. It should be a selfie taken at the first scene, where the deceased’s items were indeed seen. Each picture is a selfie of the deceased , It is unlikely that the picture will be faked. ”

“I think so, you take a closer look. The contents of these 3 pictures are also different. The first picture is just picking up trash; the second picture is sorting 2 piles of trash. The workload of this trash picking is Honestly, if a person picks up this garbage, it takes at least 2 minutes to an hour; the third picture is putting 40 piles of garbage in a garbage bag, and it takes 3 minutes to get it done. ”

Li Hui said this, moistened his throat, and continued: “That is to say, it takes at least 50 minutes to 70 minutes before and after the garbage is sorted, and then the garbage is put into the bag. ”

Zhao Ming’s results said: “On the afternoon of the 9th, the first picture of Zhang Zihan picking up garbage was issued at 2:3; the third picture was issued at 3:XNUMX, with an interval of nearly an hour, which completely matched the analysis of Brother Hui. up. ”

Han Bin took a closer look at the picture again. He also agreed with Li Hui’s analysis. From picking up garbage to bagging it, if it is a person, it takes at least an hour, but Han Bin thought of another may:

“If someone helped Zhang Zihan pick up the garbage at that time, the time for picking up the garbage would be shortened, and then take a selfie. After the killer killed Zhang Zihan, he uploaded it according to the time of one person picking up garbage.”

“I don’t think this is likely,

Zhang Zihan has no assistant, who will help her do this kind of thing. “Li Hui said.

“The murderer,” Han Bin said.

Li Hui sucked in a cold breath, and continued to analyze: “Now it is certain that the upload time of the first circle of friends should not be necessary for fraud.”

“Even if the murderer helped pick up the garbage, the time was reduced to half, and there was half an hour.” Li Hui said.

“What if the killer was two?”

Li Hui sighed: “20 minutes.”

Zhao Ming smiled bitterly. The more the situation was analyzed and the more complicated his brain became, the more his brain was not enough: “Is there a murderer with more than 10000 people, this time will not be shortened.”

Han Bin pondered for a moment: “It’s unlikely that the colleague who went with Zhang Zihan will either act alone or two people. If three people help her pick up trash, it will become two groups; if these two groups are usually Both have a bad relationship with Zhang Zihan, Zhang Zihan will not let them help pick up garbage; if they have a good relationship with Zhang Zihan, they will not be able to fight back together, so I don’t think there will be more than three people picking up garbage. ”

“That is to say, the death time of Zhang Zihan can be accurate to between 2:4 and XNUMX:XNUMX,” Li Hui analyzes.

“That said, anyone who left the park after 2:XNUMX is suspect.” Sun Xiaopeng said.

“No, after killing Zhang Zihan, you still have to drag the corpse, dig a burial, and based on the situation on the scene and my experience, it takes at least an hour. If you add this time, the killer should be after 3:XNUMX Park left, “Han Bin said.

“That is to say, those who left the park before 3:XNUMX can rule out the suspicions for the time being.” Zhao Ming said.

“From the current evidence analysis, this is indeed the case,” Han Bin replied.

“The next time I take a transcript, I have it in my heart.” Li Hui whispered.

……

“Well …” Just then, there was a knock on the door.

“Come in,” Han Bin said.

“Creak …” The office door was pushed open, and a man in his 30s came in.

The man had a mustache, a pair of golden glasses, and a briefcase in his hand.

“What’s your business?”

“My name is Wu Jianglong. I’m the anchor of Feiyu Company. I’m here to take notes.”

Han Bin was impressed with the name and pointed to the chair next to him: “Sit down.”

“Comrade Police, if you have any questions, please hurry up. I will participate in an event in a while.” Wu Jianglong glanced at his watch.

“You would save time.”

“Time is like a sponge, as long as you squeeze it, you will have it.” Wu Jianglong said.

“You usually broadcast live and talk like this?” Han Bin laughed.

“When I broadcast live, I mainly share my business experience and life insights with my fans and help them solve some work and life difficulties.”

Li Hui reminded, “This Wu Jianglong is the anchor of success.”

Han Bin laughed: “How old are you?”

“26 is old.”

“It looks very anxious.”

Wu Jianglong pushed his glasses and touched his moustache: “Some fans are young people. They always like to look at people based on their looks, so I’m more mature, you know.”

“You successfully learned the set and put it away. I will answer whatever I ask.” Han Bin lightly saying.

He couldn’t think of how much business experience and life experience a 26-year-old person can have.

“What is your relationship with Zhang Zihan?” Han Bin straight to the point.

“Colleague relations.”

“When was the last time you saw her?”

“It was on the 9th. At the gate of the botanical garden, we made a car at the time, and it was quite a conversation. She asked me for some investment suggestions.” Wu Jianglong said, and asked:

“Comrade police, is there anything wrong? What happened to Zhang Zihan.”

“Zhang Zihan is dead,” Han Bin said.

“Dead!” Wu Jianglong stared wide-eyed.

“Did you go to the botanical garden to do environmental publicity?” Han Bin asked.

“correct.”

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

Wu Jianglong shook the head: “I didn’t see it.”

“When did you leave the park?”

Wu Jianglong recalled for a moment: “More than 2 pm.”

“The specific time?”

“Can not remember.”

“Where did you go after leaving the botanical garden?”

“Go straight home.”

“What time is it home?”

“More than 3 pm.”

“Where does your family live?”

“4 Huijiayuan, Building 3, Unit 1.”

Han Bin came up with a map of the botanical garden: “Finger, UU reading www.uukanshu.com. Which piece of garbage are you cleaning up?”

Wu Jianglong stared at the map for a while, pointing to a nearby pine forest: “It should be this one.”

“Did you hear any unusual sounds while cleaning the garbage?” Han Bin asked.

“No.” Wu Jianglong complied and looked at his watch again.

Han Bin asked for a while, without asking more information, 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 more than two o’clock, he would have no time to commit the crime.”

Han Bin asked Tian Li aside: “Did the surveillance of the front and back doors of the botanical garden be brought back?”

“Bring it back,” Tian Li replied.

“Check the monitoring to see if he left at 2 o’clock,” Han Bin ordered.
