Jiang Qingrui compared the joints and soft tissues of the deceased's limbs and deduced that the deceased had not been active for at least 24 hours.

In other words, the deceased stayed in the ceiling for at least 24 hours, perhaps because the ceiling was not load-bearing enough, which caused the breakage, and the deceased was found falling from a height.

Thinking of this, there was another chill.

Who did the deceased offend? Why does the other party hate him so much?

This is not a vendetta that can be triggered by a simple quarrel.

＊

When the hour hand pointed to two, there were still many people in the bureau who were busy, and most of them used strong tea and coffee to deal with the case at hand, only Xu Shu didn't drink anything, sitting alone outside the forensic office, looking through the files in his hands.

Another half hour passed, and the door to the medical examiner's room finally opened.

Xu Shu raised his eyes when he heard the sound of the door opening, and just met Jiang Qingrui's eyes with tired eyes.

She thought Xu Shu was gone.

It's okay to be here, I just handed him the autopsy report, and I don't have to wait until tomorrow.

"The deceased died of mechanical asphyxiation and had been trapped in the ceiling for at least twenty-four hours." Jiang Qingrui resisted the urge to yawn and handed the report to Xu Shu, "It's indeed the same as you think, there are a lot of contraband in the deceased's body, and it seems that it is due to an overdose of contraband, which caused suffocation." ”

This corresponds to what Jiang Qingrui felt in the death sharing, when those people injected the deceased with contraband.

Hallucinations, not feeling much pain, breathing more and more slowly until death by suffocation, these are the causes of an overdose of contraband.

Xu Shu, who had already raised his hand to take the document, suddenly paused, and his fingers pinching the document stiffened.

Jiang Qingrui finished the autopsy with her spirit, and endured the sleepiness to complete the toxicity analysis and autopsy report, she was already sleepy at the moment, and naturally she didn't have the extra energy to pay attention to Xu Shu's abnormality.

“…… What contraband? ”

Jiang Qingrui didn't hear the unknown emotions suppressed in Xu Shu's voice, and he replied obediently when he asked anything: "Hydroxybutyric acid." ”

After answering, I didn't hear Xu Shu's reply, and I didn't see Xu Shu take the document, Jiang Qingrui finally noticed that something was wrong, and rubbed her sour eyes to look at Xu Shu.

In the next second, Xu Shu stood up suddenly.

"How is that possible!"

Jiang Qingrui kept her eyes rubbing her eyes and froze in place, staring at Xu Shu who suddenly shouted out loudly with wide eyes and frowns.

When he heard the name, he couldn't help but think back to the day many years ago, when he was leaning by the door of his study and heard the words "hydroxybutyric acid" for the first time.

At that time, a child who did not know what these four words represented would not know what kind of changes they would bring to his family.

"Hydroxybutyric acid can't appear in the sea market!" Xu Shu gritted his teeth, his brows were tightly locked, and his eyes were full of disgust and inexplicable emotions, as if he was looking at something he hated so much through the person in front of him.

Xu Shu's sudden reaction caught Jiang Qingrui by surprise, she was so frightened that her neck shrunk, and her lips subconsciously trembled to answer Xu Shu's question.

"But the deceased's body is hydroxybutyrate......"

Before Jiang Qingrui's words were finished, her arm was grabbed violently.

"You're mistaken, you must be mistaken! There can be no hydroxybutyric acid in the market! ”

Jiang Qingrui's explanation choked in her throat, and looking at Xu Shu in front of her as if she was out of control, she felt a chill slip from her spine to the top of her head.

Xu Shu was stunned, and what he saw in front of him was no longer the dusk of that day, but dark brown eyes full of astonishment and fear.

Jiang Qingrui used her strength to break free of Xu Shu's hand, holding the document and retreating several steps away from the "crazy criticism" in front of her.

Xu Shu realized his gaffe just now, his thin lips slightly opened up and wanted to say something, and his cold face, which had never changed in the past, returned with apologies.

"Sorry......"

Jiang Qingrui was almost scared to death by Xu Shu just now, and now when she heard his apology, she was very unhappy, but when she saw him lowering her eyebrows, she could only frown and wave her hand.

"Forget it, you'll be normal in the future."

In the past, if he heard Jiang Qingrui say this, Xu Shu would definitely say a few words in reverse, but today he didn't say anything else, and seemed to be immersed in some memories.

"Master, Jiang ......"

Jiang Wu found out the latest news and hurriedly walked towards the two of them, but when he stopped, he found that the atmosphere here was a little strange.

Jiang Jiang twisted his eyebrows, and the master lowered his head.

What is this scene?

Master would actually keep his head down?!

Before Jiang Wu could analyze the situation at the scene, Xu Shu, who had his head down, disappeared and returned to his usual cold face again.

"What did you find?"

Jiang Wu came back to his senses and hurriedly reported to him what he had found.

"We checked Sun Ke's usual contact network and found that Sun Ke was a gangster in Haishi City, and he didn't have a serious job, but he also checked the drug rehabilitation list, and there was no Sun Ke's name in it." Jiang Wu integrated all the information that everyone found, "Sun Ke often goes in and out of Huayuerong KTV, and seems to be a frequent visitor there, he has nothing to do on weekdays, he likes to stir things up everywhere, and he has made a lot of enemies." ”

"And the person who is most likely to take revenge on Sun Ke among these people is called Li Qiang."

Xu Shu was about to speak, but Jiang Wu continued.

"Li Qiang has been summoned, and Lin Ru, who usually contacts Sun Ke the most, has been squatted and can be summoned at any time."

Xu Shu nodded, turned around and walked towards the interrogation room.

After walking out for two steps, Xu Shu seemed to remember something, and when he looked back at the door of the forensic office, Jiang Qingrui was no longer visible.

"Comrade policeman, why did you call me so late...... What is it to do? ”

When Xu Shu walked into the interrogation room, a man who looked honest was sitting on the chair opposite.

The man looked like he was forty or fifty years old, his face was full of fine lines, his skin was dark, and his eyes were full of confusion and uneasiness when he looked at Xu Shu and Jiang Wu next to him.

Xu Shu looked through the man's file and found that this person named Li Qiang was only thirty years old.

"Li Qiang, male, 30 years old, works in a gas hair repair shop, responsible for car repair and parts maintenance, right?"

Jiang Wu got up seriously and stared at the man in front of him with a serious face.

Li Qiang was originally quite restrained, but he was even more nervous when he heard the police comrade in front of him say his information so seriously, and nodded as if he was about to cry.

"Where were you from two in the morning the day before yesterday to seven in the evening last night? What are you doing? ”

"Before, the day before yesterday?" Li Qiang was stunned all of a sudden, and he was afraid that he would be suspected, so he racked his brains to recall what he had done in the past two days, and he only had one sentence after thinking about it.

"I, I've been in the factory for the past two days......"

This is not a clear answer.

Jiang Wu looked down at the file and continued to ask:

"Is there monitoring in the garage? Can anyone prove that you have been in the factory for the past two days? ”
