The sea and the book [criminal investigation]

Shi Yuning showed Lu Nanchu the letter he had received, and said that the content of the letter was very similar to Cheng Qiyan's suicide note that he had heard back then.

He was very familiar with Cheng Qiyan, and he also knew Luo Yuhuai; he didn't believe that Luo Yuhuai cheated on Senior Sister Yulin on the Internet, and it was simply a rumor made out of nothing with ulterior motives.

Even he didn't believe that Cheng Qiyan really committed suicide.

When Yu Ning returned to Yunying four years ago, she came to find Qin Zheng and asked her, can the police really accurately distinguish whether the deceased committed suicide or homicide?At that time, Qin Zheng gave him an accurate answer, which made him believe in the professionalism of the forensic police, and no mistakes were allowed in such matters.

"Brother Nan, I can't tell. I just think that Luo guides him..." Shi Yuning didn't know how to express his thoughts to Lu Nanchu, so he hesitated for a while before saying, "You must find out the truth. I believe You will find out the truth."

"Don't worry, we will never wrong the good people, nor will we let the bad people go." Lu Nanchu patted him on the back lightly, which was also a comforting word.

Looking back and seeing Nan Zhao standing outside the door, Lu Nanchu brought water to Shi Yuning: "Drink some water first! Nan Zhao and I will go out and talk for a while."

Seeing that Lu Nanchu came out, Nanzhao handed him the surveillance video that she had copied to his mobile phone: "Look. The surveillance camera captured the flower delivery person, but the woman was so tightly dressed that she couldn't see her face clearly; according to her figure From the action, it should be a woman aged 20-30, with a height of about 165."

The woman in the video is wearing a long black dress that hits her ankles and shakes violently as she walks; she wears a wide-brimmed hat, mask and gloves, clearly coming prepared.

Lu Nanchu passed the information to Yan Geng, and focused on investigating Zhao Tian's social relationships with women aged 20-30, and investigated any suspicious ones.

The most difficult problem now is that Zhao Tian is a gangster, and the police's investigation has been greatly hindered.

"Do you think the person who sent flowers to Zhao Tian is the same person who sent flowers to Shi Xiao?" Lu Nanchu tapped on the window sill and asked, Nan Zhao lowered his eyes: "The answer is obvious. This kind of green plant is not It appeared on the market, most likely it came in through the same channel. However, brother Yu Ning was stunned by sevoflurane, but Zhao Tian's autopsy report shows that he has no trace of stun."

Moreover, sevoflurane is hidden in the green plants, which is only enough to cause Shi Yuning to faint for a short time; and the flower giver did not hurt Shi Yuning after he passed out. Surveillance showed that she passed out after seeing Shi Yuning. She left and closed the door for him.

But who is this woman?What is her real intention?

Lu Nanchu returned the mobile phone to Nan Zhao, entered the room and sat down at the position just now: "By the way, do you still remember the woman who gave you flowers, does she look like someone you know?"

"Probably not." Shi Yuning stared at the video on the phone for a while, then shook his head resolutely, "I probably don't know her."

"Okay. If she shows up next time, remember not to take anything she gave you, and then call me." Lu Nanchu told Shi Yuning, and then put away the phone.

Qin Zheng brought out the freshly cooked dry noodles and called them to come over to eat the noodles, while asking Shi Yuning: "When did you come back here?"

Shi Yuning lowered his head and pulled the dry noodles, and heard Qin Zheng's question before whispering: "Aunt Qin, if I say that I have resigned from the publishing house, will you be angry?"

"You did a good job, why did you leave the job?" Qin Zheng was very surprised, and Lu Nanchu also looked over when he heard the words: "Is it because you are unhappy at work?"

"No, it's just that I don't want to work in a publishing house anymore." Shi Yuning showed embarrassment, and shook his head after hesitating to speak.

Qin Zheng wanted to ask again, but was interrupted by Lu Nanchu: "Since I didn't want to talk about it when I was young, don't ask."

He guessed that Shi Yuning's resignation from the publishing house might have something to do with the letter he received; when Shi Yuning mentioned the resignation, his expression was very similar to the expression he had when he and Lu Nanchu mentioned receiving a strange letter just now.

After all, Qin Zheng didn't understand the situation, so Lu Nanchu interrupted her.

"It's okay to leave the job. It's just that you can rest at home for a while, adjust your mood, and don't be too tired." Qin Zheng comforted in a warm voice.

Shi Yuning still looked absent-minded, and nodded after listening to Qin Zheng's words.

Qin Zheng was worried about him, and added another sentence: "If something like today happens again, you must be careful, and then call me or tell you Brother Nan."

Shi Yuning still nodded: "Aunt Qin, don't worry. Brother Nan said the same thing just now."

"Yes, your brother Nan is the most prudent." Qin Zheng smiled reassuringly.

After eating the dry noodles, Lu Nanchu and Nan Zhao went into the kitchen to talk to Qin Zheng, and they went back to the bureau overnight to deal with it.

This time the monitoring at least captured the back of the flower giver, and sending the monitoring video to the technical department for recording was at least somewhat useful.

Just halfway through the car, Lu Nanchu received a call from Yan Geng: "Captain Lu, a murder has occurred in the Nancheng Campus of Yunying University. We found the same green flowers at the scene of the crime as in Zhao Tian's dormitory."

"Yunying University? Okay, let's go there right away." Lu Nanchu turned around at the next red light and drove to Yunying University.

The Nancheng Campus of Yunying University is less than 10 minutes away from here. When I arrived at the Nancheng Campus, I saw several police cars and ambulances parked outside. Lu Nanchu and Nan Zhao rushed to the scene of the crime.

The crime scene has been cordoned off by the police. Seeing Lu Nanchu, Yan Geng trotted over to explain the situation: "The deceased, Feng Jingjia, was a lecturer in the Department of Biomolecular Engineering at Yunying University. According to the situation at the scene, Feng Jingjia was passing by. In the laboratory building, he was hit on the head by a glass bottle thrown from high altitude, and died on the spot; but we saw at the scene of the crime that the deceased was holding a bouquet of green flowers in his arms, which were determined to be the same species as the green flowers in Zhao Tian’s dormitory plant."

The deceased had been transported away by ambulance, and only a pool of blood, glass shards, and the bunch of green flowers stained with blood remained at the scene of the crime.

Lu Nanchu went to the scene of the crime to take a look, and then went to see the evidence with Yan Geng.

In recent years, there have been many cases of death caused by high-altitude parabolic objects, but whether it is an accident or a murder case is still another matter.

Just opposite the laboratory building, there is a surveillance camera, which can take pictures of the glass bottle falling.

The monitoring accurately saw that the glass bottle was placed on the windowsill, and it looked as if it was blown off by the wind.

"Glass bottles shouldn't be placed where they are easy to fall, and it is easy to cause accidents." Lu Nanchu condemned this kind of behavior, and turned his head to Yan Geng, "The surveillance in the corridor of the laboratory building did not capture it. Did anyone put this glass bottle here? If not, do a fingerprint comparison on the glass bottle."

Yan Geng nodded quickly and agreed: "The glass bottle has been sent for fingerprint extraction and comparison. But the glass bottle is too broken, so it may not be possible to find it. The monitoring in the corridor of the laboratory building has long been broken, and it has not been repaired. Almost The origin of the glass bottle could not be traced."

It was the glass bottle that fell from high altitude that killed Feng Jingjia, but why did Feng Jingjia hold that bouquet of green flowers?And who gave him the bouquet of flowers?

Now that Feng Jingjia is dead, it is as difficult as Zhao Tian to find out who gave him the bouquet of flowers.

Or what exactly does this bouquet of green flowers represent?The two appearances were related to two murders, not to mention that the flowers were not available in the market at all.

If it is said that Feng Jingjia was killed by a parabolic object, it was actually a premeditated murder. Is this case related to Zhao Tian's case?

One is a teacher from the Biomolecular Engineering Department of Yunying University, and the other is a worker at the Nancheng Garment Factory. These two people seem to have no overlapping social circles at all;

"No, Zhao Tian's girlfriend Mu Yao is a graduate student of Yunying University." Nan Zhao reminded, "However, Nan Zhao's literature is mainly taught in Haidong Campus, and Feng Jingjia's Department of Biomolecular Engineering is Classes are held in the Nancheng campus, and the biology laboratory is also in Nancheng. If there is a social overlap between Zhao Tian and Feng Jingjia, the biggest possibility is Mu Yao."

It seems that Mu Yao is introverted and timid. When visiting relatives and friends around Mu Yao, they all commented on her like this, saying that this girl is very nice, but she is very soft-tempered and rarely communicates with others. Her favorite place to stay in school is library.

In general, Mu Yao seems to have social phobia.

But according to Mu Yao's previous account of how she and Zhao Tian got acquainted, it didn't look like something a person with social phobia could do at all.

This Mu Yao has a lot of secrets, and all kinds of unreasonable things about her make the already confusing case even more strange.

After the Feng Jingjia case, the police summoned Mu Yao again and asked her if she knew Feng Jingjia.

Mu Yao showed a dazed look, and shook his head for a moment: "I have heard of Teacher Feng's name, but I have never met Teacher Feng. I usually take classes at Haidong Campus, and have never been to Nancheng Campus; although I have known Teacher Feng's name for a long time. , but I have never met Teacher Feng."

"Long admired the name? Feng Jingjia is famous in your school?" Lu Nanchu found the point and asked.

"Of course. All the classmates in the school don't know Teacher Feng." Mu Yao nodded with his usual expression.

These circumstances are basically consistent with what the police learned.

Feng Jingjia was indeed a celebrity teacher at Yunying University. It was said that it was because he had a particularly outstanding appearance among the teachers, and he couldn't tell his real age at all. Everyone thought he was a young teacher in his early twenties.In this world where beauty is justice, a handsome and talented teacher like Feng Jingjia should be especially loved and cared by students.

And Mu Yao didn't hide it.

It's a pity that Teacher Feng, who is the most popular among the students, unexpectedly suffered such unexpected disasters and died young.

Or maybe it wasn't accidental accident at all, but deliberate murder.

The green flowers that also appear seem to be somewhat related somewhere in the dark.
