It stands to reason that Zhao Qian left the venue for more than half an hour, and if the murderer wants to commit the crime, he must only do it during this time period.

And Zhao Qian's death in the wooden box narrowed the scope of investigation.

According to the confession of the previous confessions, Gu Chen already knew that during the break in the training meeting, the general distributor Liu of the general manager who had been to the backstage, Huang Wenxing, the gold medal host, and Wu Feifei, the inspirational lecturer.

Of course, security guard Huang Zhigang was suspicious, after all, in the past 10 minutes or so, he couldn't explain where he had been and what he had done.

But according to the explanations of other security guards, Huang Zhigang never left after returning to the conference room hall.

"Officer Gu. Huang Wenxing took the initiative to walk up and said, "I heard that you want to ask me for questions?"

"That's right. Gu Chen looked at Huang Wenxing's outfit and couldn't help asking, "I remember that you didn't wear a white dress before. ”

"Oh, it's a change of clothes. Huang Wenxing didn't deny it, but for fear that Gu Chen would misunderstand, he hurriedly said: "I presided over a game, and when I took a break, I would change some coats of other colors, which is a habit." ”

"The main thing is to improve the attention of everyone in the audience, giving people a fresh and refreshing feeling, in fact, each of our lecturers has this habit, depending on whether they are diligent or not. ”

Zhang Jingde frowned, and hurriedly said, "But what if your other set of clothes is stained with the blood of the deceased?"

"What...... What?" Huang Wenxing's face stiffened with fright, and he quickly waved his hand and explained: "This officer, don't be joking, I just changed my clothes, why did you have anything to do with the deceased?"

"I just skeptical, and I didn't say it had to be. Zhang Jingde also justified himself.

Of course, why did Huang Wenxing change his clothes, if he regarded this as a personal habit, he might still say it in the past.

But now that there is a homicide, the police have to investigate any clues that could help solve the case.

"Huang Wenxing. Gu Chen walked up to him and said, "Where is your set of changed clothes?"

"In ...... In the hotel guesthouse, room 2202. Huang Wenxing said.

"Do you have a room card?" Gu Chen asked again.

"Yes...... Some. Huang Wenxing hurriedly took it out of his body, handed the room card to Gu Chen's hand, and said, "The coat is hung on the wardrobe, and you can see it when you go in." ”

Gu Chen handed over the room card to one of the policemen and said, "Trouble this senior brother, help confirm it, and get that set of clothes back by the way." ”

"Understood. An old comrade suddenly understood what Gu Chen meant.

Gu Chen asked him to pick up his clothes and check whether there were blood stains on them.

After the old comrade left, Gu Chen's inquiry did not end.

Huang Wenxing's biggest suspicion is on his coat, as long as it is verified, this suspicion can be ruled out.

However, Huang Wenxing also went backstage, so Gu Chen asked again: "When did you go backstage?"

"When to go backstage?" Huang Wenxing thought about it and said: "It was probably during the break halfway, I went backstage with Mr. Liu and Mr. Wu, and the three of us chatted about the awarding of prizes. ”

Then Mr. Liu went to the toilet, and Mr. Wu and I rested for a while in the small room in the background. ”

"There are three small rooms in the background. A hotel security guard said quickly.

Gu Chen looked at Huang Wenxing: "You were all resting in your respective small rooms at the time, right?Did you hear the movement in the backstage hall?"

Huang Wenxing was stunned for a moment and shook his head: "I was listening to music with a headset to relax, but I didn't hear anything outside, because I only had half an hour to rest, you can ask my assistant, the teaching assistant over there." ”

Huang Wenxing pointed to a man in formal clothes next to Zhang Jingde.

The man hurriedly nodded and said: "That's right, Mr. Huang's usual work is work, and during the break, he has to seize every minute and every second, no matter how tired he is, as long as he stands on the podium, he will greet all the audience with the fullest enthusiasm." ”

"Listening to music with a headset, what should I do if I miss the time?" Gao Wenjun hurriedly asked.

"No, it won't. The teaching assistant hurriedly said: "Every time Mr. Huang wants to rest, he will greet me in advance, and I will call him if I calculate the time." ”

"In other words, Huang Wenxing has been resting in the small room with a headset until you wake him up and continue to host on stage, right?" asked Gu Chen.

The teaching assistant nodded: "That's basically it, like today, Mr. Huang Wenxing was woken up by me, and then came to the scene to continue hosting, after all, there is a burgundy curtain in front of the stage and the Queen Mother, and the scene is noisy, so Mr. Huang Wenxing has been wearing a headset......

"Wait. Gu Chen suddenly interrupted the teaching assistant's words, and hurriedly asked, "Are you sure that Huang Wenxing has been staying in the room for more than half an hour, and has been wearing a headset and not moving?" Or are you watching him the whole time?"

"This ......" was asked by Gu Chen, and the teaching assistant was instantly dumbfounded.

"No, right?" Gu Chen knew the answer from the protagonist's eyes.

The teaching assistant nodded: "Yes, but Teacher Huang Wenxing has always had this habit." ”

"Okay, I got it. Gu Chen nodded, and said: "If you don't see anything with your own eyes, just relying on your previous habits can't be used as evidence for Huang Wenxing to clear his suspicion, so your subjective opinion can only be used as a reference." ”

The teaching assistant glanced at Huang Wenxing, and when he saw Huang Wenxing nodding, he didn't say anything more.

Gu Chen then turned his gaze to Huang Wenxing and said, "You are still suspicious, because you can't prove the fact that you have walked out of the small room in the past few tens of minutes. ”

"But I did rest all the time, and I really didn't know anything about what was going on outside. ”

was also the fact that he found out that he had become a suspect again, and Huang Wenxing's whole face became ugly.

At this time, the old comrade who was in charge of retrieving his clothes had already come to the hall with a suit.

Gao Wenjun hurriedly asked, "How is it?"

The old comrade shook his head: "There is no blood, the clothes are clean." ”

"That is to say, Huang Wenxing's change of clothes is really just a professional habit? Isn't it deliberately changing clothes after committing the murder?" Although Gao Wenjun was a little disappointed with this investigation, he at least denied his previous opinion.

Gu Chen did not respond directly, but walked in front of the general distributor Mr. Liu.

At this moment, Mr. Liu also found that Gu Chen's investigation was very harsh, although he had some friendship with Gu Chen's parents, but he was still a little afraid in the face of the young policeman's gaze.

"Big ...... Big nephew, this really has nothing to do with me, how do I know, how did this woman run into the box, and the prizes in my box are gone, this ...... I don't know who to talk to!"

Mr. Liu was preconceived, and first used the "eldest nephew" to close the relationship with Gu Chen.

Then he looked at Xiao Xiaofang and Gu Baichuan beside him, and hurriedly said, "Old Gu, you two husbands and wives help me talk, I am really wronged." ”

Gu Baichuan said: "Mr. Liu, our relatives cannot interfere in this police case, and we have to investigate objectively." ”

"Yes, Mr. Liu. Xiao Xiaofang also hurriedly explained: "My son has always handled cases impartially, as long as you have no problems, he will never wronged you." ”

Mr. Liu was about to cry: "But now we can't tell, compared to when Huang Wenxing and Wu Feifei went to the small room to rest, I smoked in the background for a while, and no one stopped during this time." ”

also saw Huang Wenxing before, who couldn't confirm that he had been staying in a small room and resting with headphones, so he was listed as a suspect by Gu Chen.

Now it seems that if there is no eyewitness to confirm it, no one can say what he did during this time in the background.

Therefore, Mr. Liu seemed very depressed and even helpless.

"Mr. Liu, don't worry, I didn't say that the murderer was you, you don't have to be uncomfortable. "Gu Chen is also hindered by his parents' face, and it is not good to be untrustworthy in front of the elders, especially in front of the general distributor.

If Mr. Liu is fine, then naturally there is no need to worry too much.

"Eldest nephew, I'm relieved to have your words, just ask whatever you want, your Uncle Liu must be honest. ”

It is also because Gu Chen has now led the on-site investigation, and Mr. Liu, who did not pay much attention to Gu Chen at first, also regrets it at this moment.

I knew that Gu Baichuan and Xiao Xiaofang's son was a policeman, so I should have come over to say hello just now, so as to get closer.

Gu Chen had already recorded some of his answers just now according to what Mr. Liu had said before, and asked:

"In other words, you stayed in the background for a while after Huang Wenxing and Wu Feifei entered the small room, so what happened later, where did you go later?"

"Later?" Mr. Liu hesitated for a moment and said, "Later, I went to the toilet, and then returned to the conference hall and chatted with a few dealers until the training meeting began.

Mr. Liu set his eyes on the two middle-aged men beside him.

One of the tall and thin men said: "That's right, Mr. Liu was in the conference hall, and he chatted with us until the training meeting began, and we asked him about the gifts, but he kept it a secret." ”

Another chubby man also said: "Yes, yes, yes, but it's only for ten minutes, and we can prove it during this time, and we don't know what happened before." ”

"Yes, I see. Gu Chen wrote rustling in the transcript, and then said: "In other words, the vacuum time that Mr. Liu stayed in the background can't be proved by witnesses, right?"

"Yes...... Yes. Mr. Liu did not deny it, and directly admitted: "Although I smoked a cigarette in the background and stayed for a while, I definitely did not commit murder, besides, I don't know this person at all, he is not my dealer." ”

"That's right, I invited them. ”

At this moment, the last suspect, Wu Feifei, walked up to Gu Chen a little stiffly, and said, "She is one of my VIP students, because she happened to contact me today, so I asked the organizer to reserve a few places for Zhao Qian and her friends to come over to listen to my class." ”

"Teacher Wu. Gu Chen nodded at him, and said, "Then what were you doing when you were resting?" They said that you were resting in the small room in the background, didn't you notice any movement outside the door?"

"Nope. Wu Feifei shook his head very dryly, and said: "I am the same as Huang Wenxing, when we rest, we will seize every minute and second, but once we are on the stage, we have to show enough enthusiasm to give lectures, Huang Wenxing's habit is cultivated by me." ”

Huang Wenxing hurriedly said: "Yes, my habits are indeed taught by Teacher Wu, and I am also a student of Teacher Wu." ”

"I see. Gu Chen didn't ask too much, mainly because the things that needed to be verified before were basically very clear under the sequential statements of several suspects.

Wu Feifei was also unable to confirm the fact that he had been in the room.

At this time, Zhang Jingde's apprentice Xiao Li had also explained the situation of Zhao Qian's friend Zhao Xiaofang to Gu Chen.

Zhao Xiaofang did have a quarrel with the front desk on the first floor, and it was quite long, which basically confirmed that she had no possibility of committing a crime.

In this way, the real suspect is the security guard Huang Zhigang, who had a fierce conflict with Zhao Qian, as well as the general distributor Mr. Liu, as well as the gold medal host Huang Wenxing and the inspirational lecturer Wu Feifei.

In the testimony of all people, there is a time vacuum that cannot confirm themselves.

And that time vacuum was enough for the murderer to commit murder.

"Who is it?" Gu Chen hesitated, he glanced around, and his gaze stopped on the wooden box containing the deceased Zhao Qian.

"If the murderers are these four people, why don't there be blood stains on these four people?"

Gu Chen carefully observed the four of them, almost clean, only the security guard Huang Zhigang, there were some traces of dust rubbing, which must have been generated in the process of carrying the wooden box.

"But what about the murder weapon? Since it was injured by a sharp weapon, the murder weapon must still be at the scene, and where is the gift that should have been stored in the wooden box? Could it be gone?"

After thinking of this, Gu Chen hurriedly set his eyes on Mr. Liu, the chief distributor, and hurriedly asked him, "What are the gifts you wanted to put in the golden treasure chest before?"

"This ......" Mr. Liu looked left and right, and had to say: "Actually, don't look at the big name of this golden treasure chest, in fact, the gifts inside are very small, but they are worth a lot, I just want to give everyone a visual experience through three boxes of the same size." ”

"What exactly is inside the golden wooden box?" Gu Chen asked again.

"It's a diamond necklace, it's quite a big diamond, and it's mainly awarded to the dealer who won the first place, but ......" glanced at the gold wooden box next to him, and Mr. Liu was also depressed: "But the diamond necklace is gone." ”

"I don't know why, why did a dead person suddenly appear in the box where the diamond necklace should have been placed, or a guest at the scene, this ...... I don't know what to do. ”

Mr. Liu slapped the back of his right hand on the palm of his left hand, and his face was quite ugly.

Zhang Jingde walked to Gu Chen's side and asked him: "Gu Chen, according to your investigation, only these four suspects are most likely to be murderers now, what do you want to do?"

"What else can I do?" Before Gu Chen's reply, Gao Wenjun directly interjected: "The top priority now is, of course, to find the murder weapon, as well as the missing necklace." ”

"That's right. Gu Chen also agreed with Gao Wenjun's words very much, but he still frowned.

"Do you still have questions?" Gao Wenjun asked him.

Gu Chen walked around the wooden box, turned around and said, "Senior Brother Gao, have you found any problems?" ”

"What's the problem?" Gao Wenjun asked.

"Don't you think it's suspicious that the four suspects we've locked up are clean and don't have any blood stains on the deceased?"

As soon as Gu Chen said this, Gao Wenjun also hurriedly looked at the four of them and said, "I also noticed your problem just now, that's right, the four of them are indeed quite clean." ”

"It's kind of weird. Zhang Jingde walked between the two and couldn't help thinking: "You said, since the deceased Zhao Qian was obviously killed by a sharp weapon, if the murderers are these four people, then there must be blood stains no matter what." ”

"However, according to the search I just conducted on these four people, they did not have a murder weapon, nor a diamond necklace, nor did they have the slightest trace of blood, which makes me wonder if there is a loophole in our investigation. ”

"That's right. Gu Chen directly affirmed: "Uncle Zhang, you are right, I only made a preliminary judgment on the wound of the deceased before, it was to cut the throat, but in terms of how the murderer committed the murder, I did not investigate it carefully, this is the loophole you mentioned." ”

"What do you mean......" Zhang Jingde had already guessed Gu Chen's opinion at all.

Gu Chen nodded and said, "Carry the body out, and I'll check it again." ”

Gao Wenjun suddenly glanced at the two police officers beside him, and the two police officers stepped forward reluctantly.

They first spread a white cloth on the ground, then put on gloves and masks, and carried the deceased Zhao Qian out of the wooden box onto the white cloth.

When Gu Chen stepped forward to check, everyone else retreated to the sides, while the other dealers and family members in the hall also looked at the stage quietly, quietly waiting for Gu Chen's investigation results.

"What is this?" Gu Chen put on white gloves and touched the back of the deceased Zhao Qian's head with his hand, when he suddenly found a bulging part.

Afterwards, Gu Chen continued to remove the long hair around the back of Zhao Qian's head, and found a wound with a bloody bruise.

Gu Chen suddenly stopped checking, he looked at the ground around him, and closed his eyes quietly.

At this moment, Gu Chen's mind was overturned, and with the use of entry-level imagination, Gu Chen restored the scene to the time of the accident.

During the break, everyone in the hall was chatting about common things.

At this time, Zhao Qian was communicating with people backstage, but at the moment when Zhao Qian turned around, the handle of a dagger was suddenly waved back by a man in black.

The man in black shot quickly and accurately, and the knife directly hit the back of Zhao Qian's head.

With a fierce blow, Zhao Qian was knocked to the ground by the opponent without defense.

But Zhao Qian didn't stop breathing immediately.

So the man in black opened the golden treasure chest, took out the small objects inside, and moved Zhao Qian directly into the wooden box.

Subsequently, the man in black used Zhao Qian's clothes as a block, and drew a deep blood mark between Zhao Qian's neck.

......
