Panda Criminal Investigation Team

According to all information available,

The police did a tidy up.

Cheng Longhai's body was found on the morning of May 5th,

The doors were locked when found,

The skin and lips of the deceased were cherry red,

A suicide note the size of an A4 paper was placed on the passenger seat,

The notes are identified as written by me.

Death was due to carbon monoxide poisoning,

在车厢内发现燃了一半的木炭。死亡时间推断为5月14日晚上11点至5月15日上午9点之间。由于死者于5月15日6点30分被目击从家门口出发,

又于7点13分通过高速路口，范围缩小为5月15日7点13分至9点之间。进一步算上从收费口到达山脚的时间，最有可能的死亡时间在8点至9点这一个小时之内。从法医报告推断的最可能死亡时间来看,

This is a small probability time, but it is not impossible.

In addition, the ingredients of sleeping pills were found in the body of the deceased, but no bottles of sleeping pills and water bottles for taking medicine were found in the compartment.

At the same time, judging from the concentration and distribution of sleeping pills in the body of the deceased,

The deceased was likely to have been unconscious due to drug effects before inhaling carbon monoxide, which constituted another doubtful point.

If he kills,

It may be that the murderer made the deceased take food containing sleeping pills in advance,

Lock him in the car and ignite charcoal while he is unconscious,

Then put down the suicide note,

Leave with sleeping pills and other evidence.But the suicide note was written by the deceased himself,

Why did the murderer have a letter written by the deceased?Perhaps for some reason the dead were left behind,

But since the deceased did not resist during his lifetime, what method was used to make him voluntarily leave a suicide note?

Or, as Hao Jinyang said: "It's all written by myself,

Can you still lie?I think the dead is suicide,

Fearing that his wife would find out and obstruct him, he found a quiet place to die silently.The sleeping pill bottle and water bottle were probably dropped along the way, or none at all, and two pills were thrown down the throat and swallowed in one go.I don't use water when I take medicine, how convenient it is!As for the suspicious point that Xiao Ma said, there is only one explanation, their test is wrong!In fact, isn't it that even a suspect can't be found. "

He said a big push, Yu Renjie only tilted his neck and asked him: "Zula? What's the matter with Wang Zulan?"

Hao Jinyang widened his small eyes: "What Wang Zulan?"

"Didn't you say that the deceased's wife found Zulan or something? Wang Zulan was involved in the case?"

"That's blocking, okay! Organize the blocking."

Cheng Bin let out a chuckle, and raised his head halfway through the smile: "Could the murderer have been in the car long ago? For example, the deceased met the murderer on the road and let the murderer get in the car. The murderer made him swallow the car halfway. Sleeping pills, then it makes sense that the deceased was unconscious before inhaling carbon monoxide... the murderer was actually driving the second half of the journey."

The angle of the camera on the road is not good, and it is true that the driver's face cannot be clearly captured, only the general shape can be seen.Because it was a suicide case by default at the beginning, everyone habitually thought that Cheng Longhai drove to the foot of the mountain by himself, and did not think about other situations.

Yu Renjie nodded: "For example, he made an appointment with the murderer to take pictures together, and picked up the murderer in the car on the way. If you go to take pictures, you will need cameras, tripods, hats, umbrellas... There are no commercial facilities there. If you are too lazy to go to the scenic spot for food You also need to bring sandwiches and drinks, and it’s very convenient to drug inside. The murderer can just take away the shooting equipment and garbage before getting out of the car.”

Cheng Bin immediately ordered: "Kimchi, call your favorite Ms. Zhou and ask him what the deceased took with him on the day he left home. Is there anything unusual?"

Hao Jinyang immediately called Zhou Jing, and came back a while later to report: "Ms. Zhou said that there was nothing unusual about her husband leaving on the day he left. He didn't bring any food or outdoor equipment. It seems that we were wrong, and we committed suicide in the end. Bar."

Yu Renjie frowned, with a constipated expression on his face.Hao Jinyang saw him, put his hand on his senior brother's shoulder, and comforted him: "Don't think about it, it's just that the autopsy report is wrong."

Cheng Bin pulled his hand away: "Kimchi, go and get the autopsy report. We only read the results and didn't read the content carefully. We really should study it."

Yu Renjie never liked to read boring academic reports, so he snorted immediately: "Do you understand you?"

Cheng Bin glared at him: "I don't understand, look!"

In order to frighten Cheng Bin, Yu Renjie began to read after receiving the report. He sometimes mispronounced a lot of technical terms, and sometimes broke wrong sentences.

"The cornea is transparent, the pupils are equal in size and round, with a diameter of 0.7 cm...through gas chromatography...no detection of Diazepam, Apu...Apu...uh...Apocine, and...cocaine, Nick... Chami, Nikshami... find vegetables, beef, chicken, starch, potatoes in the stomach... less chylus, only a small amount of food enters the duodenum, should die about 1 hour after the meal..."

After reading this, Fat Wei happened to pass by: "Wow, this man ate a hamburger!"

"How is it possible?" Yu Renjiezai looked at it carefully, and said with his chin in his hand, "From what you said, it really looks like a hamburger set with chicken wings and fries." Of course, these food ingredients may also be found in the box lunch, But Cheng Longhai eats in the morning, and restaurants don't provide such a rich breakfast. Even convenience stores rarely sell sandwiches containing two kinds of meat.

Fat Stomach licked his lips: "Suddenly I really want to eat a Big Mac, two pieces of thick beef! Another box of fried chicken, an egg cone, what new flavors are there recently?"

Yu Renjie looked at his chubby face and asked, "If you want to eat hamburgers and take sleeping pills, which one would you take first?"

Fat Stomach replied without hesitation: "Of course, eat the burger first! What if you take sleeping pills and fall asleep before finishing the burger?"

"Yes, most people will eat before taking medicine..." Yu Renjie opened a pack of soft candies, took one and put it in his mouth: "It takes about two hours to drive from the deceased's house to the foot of the mountain. If it is after a meal He died within an hour, and Zhou Jing said that he neither brought food out nor ate at home, so he must have eaten on the road—is there a hamburger restaurant on the road?"

"There shouldn't be any after leaving the expressway, if I remember correctly." Cheng Bin recalled: "There is one near the toll gate of the expressway, and we went in together. There may have been one before that, but if you count it backwards by an hour, no It must be what we were looking for."

Yu Renjie scratched the tip of his nose: "Oh, I remember that at the toll gate, Kimchi went in and pulled a shit."

Hao Jinyang blushed: "The third urgency in life, the third urgency in life..." He didn't expect his shit to contribute to his career.

"There is also one in Yushan Scenic Area," Yu Renjie said.

"There is one," Cheng Bin said, "The other day I asked you if you would eat chicken wings, and you went next door to buy duck necks."

At that time, Yu Renjie didn't hear Cheng Bin's words at all, and his ears were filled with the cries of hawkers, Wuhan duck neck, spicy and delicious... If the deceased had been to these two fast food restaurants, the one at the toll gate would be around 7 o'clock in the morning. It was about 8 o'clock in the scenic spot, and it was still within the time limit.

"I'll check the business hours of these two stores." Yu Renjie said, "If none of them meet the requirements, let's see if there are other small stores that meet the requirements on the road."

Yushan is located at the border, connecting the city and other provinces. The road leading to Yushan from the urban area passes through the toll gate, and there is only one main road, and the layout is relatively simple.Before arriving at Yushan Mountain, there were no other commercial facilities on the road except for a gas station and a grocery store. Even the stalls of residents were placed in the scenic spot, and the road was deserted.The investigation of fast food restaurants was extremely easy, and soon after, Yu Renjie came up with the result: "The only two fast food restaurants that met the stomach digestion conditions of the deceased along the way. The opening time is the same as the opening time of the scenic spot. The one at the expressway toll gate is open 9 hours a day."

"Did you mean M's note?"

Fat Stomach once again spoke surprisingly.

"how do you know?"

Fat Stomach stroked his chubby belly and said, "Sometimes I wake up hungry in the middle of the night and want to go out to look for food. Burger restaurants don't remember to be conscientious. There are a few in the urban area that are open all day."

Cheng Bin and Yu Renjie immediately went to the m account at the toll gate to collect evidence.Once again, Hao Jinyang, who had no sense of existence, was left in the office.

Fat Stomach draped his shoulders and asked, "Want to eat a hamburger?"

Hao Jinyang nodded: "Let's leave quickly while the captain and senior brother are away!"

Cheng Bin and Yu Renjie were lucky. The waiter on duty this day was Ms. Chen who was on duty on May 5th.After listening to the two people's descriptions of Cheng Longhai's appearance and clothing, Ms. Chen expressed that she had an impression.

"That day a man in a gray trench coat came to buy breakfast. He seemed to be a little fatter than you describe. He came early in the morning, probably when I just got off work. When ordering, he asked me for directions. Asked me if I knew there was a suicide shrine nearby or something. I thought he was a reporter who was going to do an interview, so I took a few extra glances at him."

Cheng Longhai is likely to ask such questions. Cheng Bin and Yu Renjie looked at each other and asked, "Can you call up the monitoring from 6:50 to 7:13 that morning?"

Ms. Chen immediately called the store manager and asked him for help.After a while, the two watched the surveillance video of that time period in the lounge.

At 7:02 a.m. that day, a man wearing a long gray windbreaker entered the fast food restaurant. He was wearing a peaked cap, and the details of his face could not be seen clearly, but judging from his attire and the hat on his head, it was true. Corresponds to the clothing worn by the deceased when found.This person should be Cheng Longhai, that's right.

With this video and the clerk's testimony, especially his conversation about the place where he committed suicide, it can be basically deduced that Cheng Longhai committed suicide.As for the forensic report, perhaps it really fell into a small probability event.

Even so, Cheng Longhai's body was cremated, and the case was still pending.Yu Renjie did not submit the report on this case, and even Cheng Bin's boss, Feng Bo, came to urge him twice.

Cheng Bin knocked on his desk with his knuckles after several unsuccessful reminders, and said sternly, "You have delayed a report for so long, it's too much! At that time, the credit of our entire squadron's busy year will be yours alone." The case has been delayed, how are you going to explain it to everyone?"

Yu Renjie raised his head from the computer, with a nasal voice: "Didn't I catch a cold and have no strength to work. But you know the overall speed of our situation, no matter how bad I am, I'm better than others, right?" Why did the boss know about a suicide case?"

Only then did Cheng Bin soften his tone: "The deceased's wife exerted pressure on her superiors through the relationship between the upper-level leaders. If you know, you should hurry up." He paused, and asked somewhat unnaturally: "It's just passed. How long did it take to catch a cold again? Your body is paper?"

"I'm fleshy!" Yu Renjie retorted, he has always disliked topics related to health.

Cheng Bin glared at him: "Have you coughed?"

"No, viral, don't you curse me."

"It's fine if you don't cough. I'll give you two days to hand in the report. I hope to see the finished report on my desk the day after tomorrow. Not a single typo is allowed. Do you hear me?"

Yu Renjie waved his hand to him, like chasing flies: "Okay, okay, go away!" Afraid of being bored in his tone, he added: "In case I give you a cold."

The corners of Cheng Bin's mouth curled up, and he said, "It's okay, I'm not like you. I'm in good health." Even so, he walked away sensibly.

Two days later, Yu Renjie still hadn't finished typing the report.It wasn't that he procrastinated on purpose, but that the cold suddenly worsened, and the fever reached 38 degrees 5. He had to take sick leave and lie at home for a day, and then went to work after the fever subsided.Fortunately, there have not been many cases recently, otherwise, I would probably be called to the scene of the case while lying in the coffin.

When passing by the m office near the police station, Yu Renjie suddenly wanted to go in and buy breakfast.Just as he looked up at the menu, the boss's call came.Cheng Bin's voice was as cold and impatient as ever: "Are you coming to work today?"

"Come."

"Are you feeling better?"

"much better."

"What about you?"

"I'll be there right away, I'll buy some breakfast."

"Hurry up! Bring me a copy by the way."

"What do you want to eat?"

"What can I choose?"

"Wait a minute...pork tenderloin egg burger, bacon egg burger, ham burger, chicken steak burger, plain chicken burger, hash browns, coffee, soy milk, fried dough sticks..."

"Okay, okay, don't read it, it's giving me a headache. Send me these messages, and I'll get back to you later. Also, I want soy milk."
