Jiang Feng said: "We don't know the murderer's motive yet, but we can be sure that the relationship between the murderer and the deceased should be good, or the kitchen staff in the store." ”

"Because to complete this accidental murder, the first thing is to know the existence of the secret room."

After explaining to Xiao Fang, Jiang Feng glanced at Qin Hai and said, "Team Qin, this is the jurisdiction of our Sea Viewing Institute, shall I call the director?" Let him send someone to cordon off the scene, and at the same time let the forensic doctor take the body away for an autopsy to see if there are common poisons in the stomach, the HBCO saturation in the blood, whether there is a possibility of disease and death, and conduct a qualitative and quantitative test of the heart and blood to determine whether the cause of death of the deceased is consistent with our speculation? ”

Qin Hai nodded, he didn't refuse, and the look in his eyes at Jiang Feng was even more like looking at a monster.

Do you know about the technical team and the forensic doctor? The current police academy has trained new police officers so comprehensively, just like other professions in society, they are all cross-lined?

The young policeman Xiao Fang burst into tears, and he suffered a big loss if he didn't study in the police academy and only studied in P.

"P big mistake me!" The young policeman Xiao Fang let out an unwilling roar in his heart.

With the consent of the leaders present, Jiang Feng, as a trainee reporting policeman, has the power to act, all of which is in line with the process norms. Immediately, he picked up his mobile phone and directly called Zheng Daodao's personal phone number.

"Director, probationary police officer Jiang Feng will report to you by phone!"

Zheng Daodao's laughing voice came from the phone: "How is it?" Have you had a good meal? Then come to the office to report. ”

Jiang Feng said: "Director, I was eating at the Guo Fuyang restaurant nearby, there was a murder here, the deceased was Guo Fuyang, the owner of Guo Fuyang restaurant, an adult male, about 45 years old, according to the description of the store personnel and the stiffness of the corpse, the time of death should be within 6 hours, there was excessive drinking before death, injection of drug heroin, but none of them were the cause of death, and the cause of death I personally speculated that it was carbon monoxide poisoning." ”

Sea view.

Zheng Daodao swallowed.

His originally smiling face froze suddenly.

This...... I'll just ask you to take someone to eat nearby, and then you will encounter a murder?

This kid is possessed by death, right?

Zheng Daodao was stunned for a moment, and secretly decided in his heart to wait for Jiang Feng to come to the office, let him pay more respects to Guan Gong, and go to get rid of the bad luck on his body.

"Murder? Qin Hai is with you, right? ”

"Yes, right next to me."

"Cheng, let Qin Hai answer the phone, you are young and young, you don't understand the Tao in the murder case, before the people in the institute arrive, every move is under Qin Hai's command."

When Jiang Feng heard this, he handed the mobile phone to Qin Hai: "Team Qin, our director has something to tell you." ”

Qin Hai took the mobile phone and identified himself, he heard a burst of praise, and in a word, he summed it up: Qin Hai, you are a good person, the old-timers bring more young people, and young people are not sensible and take care of them, you kid is very capable, and you solve the case so quickly......

Qin Hai, who listened to this call, was stunned, and he saw Jiang Feng's young and handsome unreasonable face, and his heart was full of bitterness.

This is all done by Jiang Feng, what does it matter to my seniors?

If he hadn't seen Jiang Feng's ability with his own eyes, he would have known that Zheng Daodao might have misunderstood.

If someone else hears it at first glance, it will definitely explode, because if you know the reason, Zheng Daodao's words sound completely naked mockery.

Eventually, the phone hung up.

......

Sea view.

Zheng Daodao looked to the side, the instructor Fang Feng, who was originally lowering his head to pick up rice.

At this moment, the shredded potatoes in Fang Feng's mouth squirted out, and he didn't bother to wipe his mouth.

Fang Feng looked at Zheng Daodao dumbfounded, and asked blankly, "Jiang Feng...... Murder again? Or did it happen in our jurisdiction? ”

Zheng Daodao nodded.

Fang Feng was speechless, he was silent for a few seconds before he said with difficulty: "What kind of luck is this kid?" ”

"On the first day of reporting, there were two murders, and we have no such precedent in the city, right?"

Zheng Daodao helplessly spread his hands and said: "Don't say it, you continue to eat, I'll take someone to the police." ”

Fang Feng wiped his mouth with a piece of paper and said, "Let's go together, there is no one in the institute at this time, just bring the three trainee policemen who came to report today with them, let them increase their knowledge, and first have a psychological preparation to do our business." ”

Zheng Daodao nodded, waved his hand and said, "Okay, let's go." ”

......

Back kitchen.

Qin Hai, Jiang Feng, and the young policeman Xiao Fang are getting together right now.

Just now, after hanging up the phone, Jiang Feng obtained Qin Hai's consent, and the group walked through the lobby and briefly asked the people in the back kitchen for some information.

Qin Hai asked, "Jiang Feng, what are the gains?" ”

Jiang Feng said: "Judging from the questioning just now, the scope of the murderer has been further narrowed. ”

"The existence of the secret room, except for the people in the back kitchen, few people know about it, and the people who know that the boss Guo Fuyang will enter the secret room for a long time every Tuesday morning are the only people who are on duty on Tuesday in the back kitchen. Of course, the possibility of transmission to the outside world is not ruled out, but the scope is basically limited to the kitchen staff. ”

"It can also be seen from the use of high-grade charcoal that the murderer should be a chef, and he is also a chef with a certain culture, otherwise he would not have thought of using a large amount of odorless carbon monoxide produced by the incomplete combustion of high-grade charcoal to commit a secret room murder."

"Combining these two points, there is no need to startle the snake for the time being, just wait for the arrival of the police officers of our sea viewing center, after sealing the scene, and then use the police to check everyone's educational information, you can further lock the scope of the murderer."

"At the same time, acquaintances commit crimes, and their motives for committing crimes are roughly daily contradictions, or economic disputes, and then let people find out the contradictions and disputes between each person and the deceased, and basically the murderer can be determined."

"The only problem is...... We need to find evidence, otherwise speculation alone will not allow the murderer to be brought to justice. ”

Jiang Feng recounted while looking for it in the back kitchen: "The back kitchen staff is messy, the fingerprints are dense, it is not easy to find fingerprint information from it for trace inspection, and there is no monitoring installed in the store, but a fake handle is placed to deter guests, and it is impossible to lock the personnel who enter and exit the back kitchen in the morning." ”

"But there's one thing that the killer may have overlooked."

Jiang Feng's gaze fell on a slip in the kitchen clutter.

"The price of this high-grade charcoal is not cheap, ordinary people will not think of using this charcoal, and for the staff in the back kitchen, its price is too expensive and not something that the salary can afford."

"Especially with the murderer's goal of making the carbon monoxide in the back kitchen and the secret room reach a lethal amount, the amount of charcoal required is a very staggering number."

"We can trace the source of this amount of high-grade charcoal transactions, and at the same time, we can check whether the kitchen staff have recently borrowed large amounts of money on the Internet or in reality."

As he spoke, Jiang Feng picked up a spice purchase list on the sundries.

Looking at it, his eyes suddenly froze.

There was a feeling of crying and laughing, which suddenly appeared in Jiang Feng's heart.

The murderer is too clever to calculate? On the spice purchase list, the restaurant today bought a huge amount of high-grade charcoal, hundreds of kilograms.

So much high-grade charcoal, calculated based on the daily order volume of Guo Fuyang Restaurant, it will not be used up in a month.

The young policeman Xiao Fang looked at Jiang Feng stunned, and he asked, "Officer Jiang, what did you find?" ”

Jiang Feng smiled and said, "The murderer, he was exposed. ”

"I think I already know who the killer is."
