This is Valentine's Day in the fourth year, and Gu Yuan walks into a flower shop, carefully selects a bouquet of roses, and prepares to pay.

"Sir, a total of 1188 yuan" The clerk looked at the rose with some envy, "Your girlfriend is so happy." ”

"Well," Gu Yuan lowered his head and sniffed the scent of roses, "but it's not a girlfriend, it's a boyfriend." ”

"Huh?" the clerk's face changed instantly, a little surprised.

Gu Yuan ignored the clerk's gaze, raised his head and walked out with flowers in his arms, he had been working abroad for a year, and he didn't know if he missed each other as much as he did. Thinking like this, Gu Yuan quickened his pace, wishing he could see his sweetheart earlier.

Valentine's Day night is the best time to make money, and drivers are waiting to pull out late-night orders. A taxi driver sat in the car chatting on WeChat, smiling stupidly.

Suddenly, a bloody palm slammed into the window glass, causing the driver's hand to shake and drop the phone.

The driver hurriedly rolled down the glass and poked his head out to find out, the people around the car had gathered, and there was an exclamation, many girls were so frightened that they hid behind their boyfriends, and no one dared to come.

"Call 120!" the crowd didn't know who shouted, so that the confused driver reacted and fumbled with his mobile phone, and saw that someone had already dialed the emergency number, and the driver didn't pay attention to it, holding the mobile phone and watching the changes.

Who knew that the girl who had just fallen to the ground grabbed the window frame and wanted to stand up, but the driver opened the car door and got out of the car, helped her to sit up, and said to the girl, "Don't lie to me, are you going to say something?"

The girl lost the strength to lower her head, and her chin was barely held on the driver's phone, and she muttered in an extremely weak voice.

"What?" the driver lowered his head, looked at the people around him and pointed at him, and scolded in his heart, "A bunch of indifferent things, don't say anything about coming to help." ”

The girl fainted after speaking, and then the driver saw that there were many holes in her stomach, gurgling out. When the ambulance arrived, the crowd of onlookers around had the courage to gradually come over to see the excitement.

The girl was lifted into the ambulance, and the police car followed. The driver secretly complained, this is good, I have to go to the bureau if I have nothing to do.

He looked at the bloodstained phone, "I'll go, what the hell is this." Recording?" The driver pressed back impatiently, and now he doesn't have time to care about this.

The policeman walked over, looked at the surroundings and motioned for him to go back to the police station with him to make a record, and the driver had no choice but to agree.

The investigation learned that the injured person lived in the residential building in the back, and coincidentally, most of the residents were out on a date tonight, so there were no eyewitnesses.

"How many floors does the injured live on?" Looking at the large pool of blood on the fourth floor, extending all the way down, Lin Mu felt that the fourth floor was where she was killed.

"She lives on the eighth floor, there is no monitoring here, ......tsk," Zheng Wei said, noticing the marks on the wall, "there is a bloody handprint." ”

Lin Mu looked at where he said, "See, this should be caused by the wall after she was stabbed." And if you look at the traces of friction on the ground, it should have been pulled. ”

Zheng Wei answered a phone call, turned around and said to Lin Mu, "The rescue is ineffective...... Our colleagues have already rushed over. ”

The expected result made them fall silent, and it would be good if they were rescued, so that there would be a chance to ask the murderer directly.

After collecting traces and footprints at the scene, Lin Mu and his party took the driver back to the police station. The body was transported, along with several family members. The mother of the deceased cried diligently, and a good-looking boy next to her supported her.

The driver had already left after 1510's explanation, and it could be judged from the surveillance of the store in front of the residential building that the girl was stabbed and ran out holding her stomach to ask for help.

"Hello, are you a family member of the deceased?" Considering the current state of the deceased's mother, Lin Mu had to look at the boy next to him.

"I'm her fiancé. The boy nodded, "You can ask me if there's anything." ”

"You should have seen it, the ring on your fiancée's hand was snatched, and our preliminary estimate is that it was a robbery and murder. ”

After listening to this, the boy just responded lightly, and did not have too much emotion.

"Yesterday on Valentine's Day, you didn't have a date?"

"No, we don't love this kind of festival. The boy's reaction was too calm, which couldn't help but make Lin Mu suspicious. He looked at the boy's hand, there were marks of wearing a ring, but the ring was not on his hand, it must have been removed recently.

His gaze moved upward, and his final gaze stayed on a red mark on the boy's neck, and Lin Mu thought to himself, maybe when his fiancée had an accident, he was still with other women.

Seeing the policeman looking at his neck, the boy lifted his collar a little uncomfortably. He cleared his throat and said, "Is there anything else you want to ask, if it's okay, I'll accompany my aunt back first." ”

"Leave a contact information. Lin Mu handed over the pen and paper, and the boy quickly wrote down a string of numbers and returned it.

"What do you call it?"

"Chi Yu. ”

"Okay, Mr. Chi, thank you for your cooperation. Chi Yu nodded again and turned to leave.

According to the surveillance of the shop in front of the residential building, the deceased came home from work and was stabbed for less than 20 minutes, but he did not follow the person. Then there is only one possibility left, the murderer was ambushed in the building in advance.

What is worrying is that there are no suspected robbers on the surveillance, and they are all brightly dressed office workers who come and go in a hurry.

"Bailan, you continue to watch the surveillance, find out the people you think are suspicious, and don't let go of anything suspicious. After Lin Mu finished instructing, he said to Zheng Wei: "Let's go to the scene of the crime again." ”

The residential buildings that have experienced the murder are no different from usual, except for the bloodstains on the purpose, and people still come and go in a hurry, only occasionally discussing a sentence or two.

Lin Mu pointed to the bottom of the entrance staircase and said, "Will you hide here?" Zheng Wei looked at it, and walked over and squatted down, "It's possible, it's totally possible." ”

"Will there be any traces left behind......

"Forget it, instead of working hard here, let's go investigate whether it's a vendetta or something. ”

"Do you have any suspicions?" Lin Mu looked at Zheng Wei, wanting to hear his idea.

"Don't you think it's strange that Chi Yu? According to the investigation, they have been in prison for a year, and they shouldn't react like that if they are not in a bad relationship, right? Anyway, it's a fiancée, and she died so miserably......

Zheng Wei suddenly realized what was wrong, and quickly shut up, don't turn his head, hit his mouth twice with his hand, and muttered, "What are you talking about, what are you talking about......?"

"I also think it's suspicious, but how could the deceased's ring be robbed?" According to Zhen Zheng, the deceased's ring was torn off, and the back of the murderer's hand should have been scratched in the panic, because skin tissue that did not belong to the deceased was found in the nails.

Seeing that Lin Mu didn't care, Zheng Wei put his mind at ease and guessed, "Is it any of them whose little lover is hated because of love?"

"I can't say exactly. Lin Mu took out his mobile phone as he spoke, and picked up a call.

At this time, Chi Yu looked at the crying Lu Ran's family, and felt inexplicably depressed. It's not that he's ruthless, it's that now he has a bigger worry, and he can only secretly pray that it's not what he thinks. After thinking about it again, Chi Yu decided to go to that person and find out the truth.

Lin Mu received a call from Bai Lan, who told them that there were two people who were very suspicious that day. One was a guy who lived on the third floor of that building and hadn't been out since he got home in the afternoon. The other one doesn't live here, but he stayed in until the time of the crime from the time he entered.

The man on the third floor immediately became vigilant when he saw the two strange men, only showing one head and yelling impatiently, "What are you doing?"

"We are the police, and there are some things about the case of Lu Ran on the fourth floor, and I hope you will cooperate with the investigation. Hearing the word policeman, the man was a little panicked, softened his tone and said, "I don't know anything." ”

"Did you hear anything at the time?"

The man thought for a moment, and quickly rolled his eyes, "No." I was tired from work and sleeping. ”

"Didn't hear anything?" Lu Ran was stabbed several times, how could he not scream. "No, no, please, don't bother me, I still have a lot of things at home!"

"Then you ......" Before Lin Mu could finish speaking, the man slammed the door shut, and vaguely heard the sound of kicking off tables and chairs inside.

Lin Mu had no choice but to give up for the time being, and instead investigated another person who had been in and out of the residential building at the time of the crime.

According to the information, his name is Gu Yuan, the general manager of a listed company, and he only returned to China on the eve of Valentine's Day. "He just came here after returning to China, what does he have to do with Lu Ran?" Lin Mu thought to himself, and Zheng Wei also gossiped, "Maybe he likes Lu Ran, and he can't stand Lu Ran marrying someone else, so he killed her." I said the relationship was a little too complicated. Lin Mu didn't say anything, and drove the car and looked ahead.

Soon arrived at Gu Yuan's company, but was told that he did not come to work today, and learned of his residence, so he had no choice but to change direction and rush to his home.
