Panda Criminal Investigation Team

Xiao Ma came to the branch to report the next morning.He was wearing gray jeans,

plaid shirt buttoned wrong,

hair crooked to one side,

It made Yu Renjie very neat.

"Remember me? I am Ma Zaiting,

The colleague who checked the Audi case together that day. "

Yu Renjie nodded,

Concerned: "Is it very windy outside?"

"fine,

Today the wind gust is three to four,

not big. Xiao Ma replied, wondering what the meaning of wind power was.

Cheng Bin came to shake hands with him: "Don't pay attention to him, he's talking about your hair." He stopped,

The corner of his mouth twitched suddenly: "If you pay attention to him, he will continue to speculate that the wind direction is north, and the direction from you to here is east-west."

"I overslept this morning,

Didn't have time to comb. "

The pony scratched his head in embarrassment,

He didn't realize that Cheng Bin was laughing at him too.

"Have you been to the Science and Technology Brigade?" Cheng Bin asked.The official name of the forensic department in the public security department is the Criminal Science and Technology Brigade, referred to as the Science and Technology Brigade,

It sounds similar to the Agricultural Production Technology Brigade,

The people in the department forced everyone to call them the forensics department.

"go immediately,

I'm here to say hi to you.Then I will go now! The pony then rashly disappeared from the sight of the second team.

Though the pony came all the way,

Also made a whole set of inspection plan,

When you get to someone else's territory, you still have to bow your head,

At best, he served as a soy sauce assistant.No one knows when he left, he has long been forgotten.

After that, Xiao Ma came here for a few days, and every time the hair on one side appeared shiny,

and left unknowingly,

Some elusive meaning.

The result of handwriting identification came out first, and the report showed that the handwriting on the suicide note was indeed Cheng Longhai's.Then I interviewed the old lady who was a neighbor in Zhou Jing's mouth. The old lady did remember seeing Cheng Longhai driving away that day, and she chatted with her for a while at the door of the house as Zhou Jing said. The time was around 06:30 about.

From the deceased's house to Yushan, there is one and only one high-speed toll gate.At the toll gate, we found a record of Cheng Longhai's license plate passing on May 5 at 15:7 in the morning - Cheng Longhai was still alive at that time.

These evidences all pointed in one direction. Cheng Longhai did indeed set off early in the morning, entered the forest near the scenic spot, left behind the suicide note, and left the personnel affairs.

When it was almost certain that the cause of death was suicide, the forensic medical report was released.Xiao Ma specially invited Ying to come to announce the result, he stroked his hair facing one side and spoke excitedly.

“死者皮肤与嘴唇呈现樱粉色，死因是一氧化碳中毒——这点我们都知道。由于车内充满一氧化碳的关系，死亡时间误差增大，范围从5月14日晚上11点至5月15日上午9点，最有可能的时间段为5月15日凌晨2点至4点之间。”

Cheng Bin pondered: "Cheng Longhai arrived at the intersection of the expressway at 5:15 am on May 7th. If the road conditions are good, he should be able to reach the foot of the mountain in an hour, barely within the time limit."

Yu Renjie interrupted with a pinch of red-flavored potato chips: "How should I put it, stepping on the timeline, I always feel uncomfortable. Aren't the two hours before and after in a general forensic report considered an extreme situation?"

Cheng Bin glanced at him and said, "Assuming you know a lot, the forensic doctor is here, let others tell you."

Unexpectedly, Xiao Ma gave Yu Renjie a thumbs up: "You are right. Although the time period is given in the report, the first hour and the last hour are generally inaccurate. They are the values ​​​​in extreme cases. The car is a confined space. , Carbon monoxide will delay the decay of the corpse. At that time, the maximum concentration of carbon monoxide, the speed of leakage from the inside of the car, and the temperature inside the car were all unknown, and the person died for another three days before being discovered, so the range of death time is so wide.”

Cheng Bin nodded: "Understood, then is it possible that the deceased died after 8 o'clock?"

"Yes, even in extreme cases it is not impossible..."

Cheng Bin immediately gave Yu Renjie a provocative look.

But Xiao Ma took a breath and immediately added: "It's just that the possibility is very small, it can be said to be very small."

This time it was Yu Renjie's turn to look at Cheng Bin with his nostrils.

Cheng Bin said to Xiao Ma with a dark face: "Can you finish the sentence in one breath?"

"I haven't gotten to the point yet."

The pony scratched his head shyly.

He took another breath, and said: "Your guess is correct. During the autopsy, it was found that the blood of the deceased contained sleeping pills. Although the concentration was not lethal, it was enough to cause coma. It’s understandable to take sleeping pills at the same time to relieve your pain. Of course, it’s useless to do so-the process of taking sleeping pills is still very painful, but when it’s uncomfortable, people have no strength to struggle. It’s just a look of peace. .Many people feel so uncomfortable after taking sleeping pills that they call 120 for help. But this time the sleeping pills are a bit strange..."

"How to say?"

"From the concentration of Diazepam in the blood and the distribution in different organs..."

"Speak human." Cheng Bin patted his left shoulder.

"Oh, Diazepam is the active ingredient of sleeping pills, I forgot you don't understand. Judging from the concentration of carboxyhemoglobin, the degree of damage to the respiratory tract, the condition of the nasal cavity and eye membranes..."

"Get to the point." Yu Renjie patted his right shoulder.

Xiao Ma learned his lesson this time: "I'm afraid the deceased was unconscious before inhaling carbon monoxide."

"That is to say..."

"There may be someone else who burns charcoal for him."

Yu Renjie avoided Cheng Bin's outstretched hand: "We didn't find a bottle of sleeping pills in the car either. Thinking about it this way, a person who is about to commit suicide wouldn't deliberately throw away the bottle?"

Cheng Bin finally managed to grab his potato chips, and concluded: "The possibility of killing him is very high."

When Yu Renjie sealed the bag of potato chips, Hao Jinyang came in.He rushed over in a hurry, scaring Yu Renjie to hide the potato chips behind his back.Hao Jinyang was not interested in his potato chips, so he went straight to the pony: "Is the appraisal result out?"

"It's coming out, wait a minute."

The pony grinned at him.

"That's right!" Hao Jinyang said, "You guys talk first, I'll make a call."

Seeing Hao Jinyang crying and laughing into the phone, Yu Renjie hooked his finger to Cheng Bin: "Hey, who do you think he is calling?"

"You don't care about him." Cheng Bin knew that he was imitating himself on purpose, so he slapped his finger off in anger, only to touch a layer of red monosodium glutamate powder.He looked at his fingers in a daze, not knowing whether to lick the powder into his mouth or rub it off.

Yu Renjie said badly, and rushed over to take the microphone: "Hello, is it Ms. Zhou? I'm Xiaoyu from the police station... No, the cause of death has not been confirmed yet... Are you free today? Let's come to your house once..."

After hanging up the phone, Yu Renjie cut Hao Jinyang straight away, calling him an idiot while cutting.Hao Jinyang dodged and dodged: "Isn't it suicide? There are records at the toll gates of the highway, it's suicide."

"I'm so mad at you, why are you so stupid!" Yu Renjie swung the bag of potato chips and hit him on the head, the potato chips made a sound of shattering. Hearing the crisp sound, Yu Renjie's heart also broke.

Cheng Bin pulled him away: "Why are you talking, and you're making personal attacks!" He snatched his potato chips and comforted Hao Jinyang: "Then who, do you want me to change your leader?"

Hao Jinyang glanced at Yu Renjie, flatteringly said no: "I just like senior brother, senior brother is right."

Cheng Bin nodded unhappy when he heard the boss, and said to Yu Renjie: "We will go to Zhou Jing's house in a while, and you can tell me when you make an appointment."

Hao Jinyang then said: "Brother, call me before you leave, I'm going to hand in a report later."

The corner of Cheng Bin's mouth slanted, and he glared at him: "If you hand in the report slowly, Zhou Jing's family won't have to follow."

"What am I doing at that moment?"

Hao Jinyang said aggrievedly.

"After handing in the report, you go to investigate the monitoring record at the toll booth to confirm whether that Audi has ever appeared."

"Okay, captain." Hao Jinyang replied disappointedly, he didn't like watching surveillance the most.

Two hours later, Cheng Bin and Yu Renjie sat at Zhou Jing's home.On the wall behind the sofa is a wedding photo of the two of them. The two people in the photo are not young, and the frame is brand new, without a trace of dust.

Zhou Jing explained: "The photo was taken three years ago. We didn't have money to take it when we got married. Long Hai said he would make it up." Her smile was very bitter, and her drooping profile looked like a lonely oil painting.

Cheng Bin has always been straight to the point: "Ms. Zhou, we are here to tell you that your husband may not have committed suicide. The specific details are temporarily inconvenient to disclose. Please cooperate with our investigation."

Zhou Jing raised her head, opened her mouth slightly, a little surprised: "Is it... Could it be homicide? If there is anything I can do to help, I will try my best."

"Then, please recall, among the people you know, who has had a holiday with your husband, or has any suspicious things."

Zhou Jing put her hands on her knees and pulled her skirt unconsciously: "My husband is honest and honest, and never complains. Who would harm him? If there is, there is only one... But it shouldn't be he…"

"Who are you referring to?"

The corners of Zhou Jing's skirt were wrinkled into a ball: "My brother, Zhou Peng."

The Zhou Peng in Zhou Jing's mouth was ignorant since he was a child, and he was proficient in eating, drinking, whoring and gambling, except that he didn't have a serious job.After Cheng Longhai started his own company, he came to seek refuge and found a job to make a living.But he was not satisfied, and relying on the fact that he was the boss's relative to misbehave, he even embezzled more than [-] yuan of public funds, and was finally invited out of the company by Cheng Longhai.

In the past two years, he borrowed another 50 yuan from his sister in order to buy a house and get married, which has not been repaid.Just recently, he asked the lion to borrow another 20 yuan to buy a car, but Cheng Longhai flatly refused.At that time Zhou Peng was very angry, called him a white-eyed wolf, slammed the door and left after making a scene.Cheng Longhai couldn't swallow this breath, and asked him to pay back the money immediately. Not only did he have to pay back the house payment of 50 yuan, but he also had to pay back the money he had obtained illegally from the company before, which made him feel embarrassing for a while.

"If he kills your husband, he can pay back more than 60 less, is that right?" Cheng Bin confirmed.

"Yes, he is my brother after all. If he doesn't give it to me, I won't ask him for it." Zhou Jing replied weakly.

"Is there an IOU for the money he owes?"

"Probably, it's all handled by my husband. I'm not sure. Maybe not."

"Is there anyone else suspicious besides him?"

"No, I really can't think of anyone else. Long Hai's life is two o'clock and one line every day. Maybe you can go to his company and ask."

After that, the two left Zhou Jing's house and went to Cheng Longhai's company.This is a small company with only ten employees, and the personnel structure is relatively simple.After doing a little research, I didn't get any useful information.Everyone said that the company's performance has not been good recently, but there are no property disputes or enemies.

Zhou Jing herself went to a nearby vegetable market to buy vegetables that morning, as neighbors and stall owners can attest.Then, Zhou Peng is the only suspect involved in the case.

After a series of investigations, Hao Jinyang found the Audi A3682 with the license plate A6 in the surveillance video of the expressway toll gate, which appeared in the camera on the morning of May 5.At the same time, Zhou Peng has an impeccable alibi.

By coincidence that day, Zhou Peng took an early morning train to another city to attend a friend's wedding. He also went with an old classmate. They met at the train station.The departure time of the train was 8:35 in the morning, the ticket was authenticated by real name, and Zhou Peng was caught waiting for the train in the surveillance video of the waiting hall.He had an argument with a migrant worker that day, causing chaos.As soon as the staff saw his photo, they said that they had an impression of him, and that he was an out-and-out bastard.

It takes about an hour's drive from the high-speed toll gate to the foot of the mountain, while the train station is in the opposite direction of Yushan, about two hours' drive from Yushan.

If Zhou Peng arranges Cheng Longhai at the foot of the mountain and then kills him, unless he can control the somersault cloud for a thousand miles a day, it is impossible to rush from the foot of the mountain to the distant train station before 8:35.
