The scene was silent, and the invisible pressure was permeating.

Gao Jun didn't care at all, suddenly grinned, and said: "I just said that this murder case is very ingenious, and unscrupulous, and it actually did it in front of everyone's eyes, this scheming, this wisdom is amazing."

There are three crucial factors in the occurrence of a homicide, one is the motive for the killing, the second is the method of killing, and the third is the murder weapon. These three points are also the key for the police to lock down the suspect and solve the case. ”

Gao Jun said that it felt as if he was teaching a lesson to the police officers present.

Immediately after that, he changed his words, put away his smiling face, and said seriously: "In this case, the murderer hides these three points that should be hidden, and the clever use of them, if they are not carefully analyzed, they are really untraceable.

First of all, let's talk about motivation......"

I don't know if Gao Jun has been a substitute teacher for a long time recently, or if he has been imperceptibly infected by Zhang Jiao, a police instructor, in such a terrible atmosphere, there is a bit of teaching flavor.

Now not only the classmates are looking at him, but even the police officers who came out of the scene are also very interested.

After Gao Jun finished speaking, he picked up the remote control in his hand and moved the progress bar backwards, accurately locking it at the position of thirty-seven minutes and twenty-eight seconds.

People thought he was pressing it randomly, but when the picture froze, they were shocked.

The picture is the picture when Zhang Yanbing and Xia Li are sitting together biting their ears and whispering, obviously not Gao Jun did it casually, this instant memory, the ability to never forget is staggering.

Gao Jun played the picture, pausing every two seconds, Xia Li in the picture is like a face-changing actor in Sichuan Opera, her facial expression changes every two seconds, a rich and short-lived expression change, and only scheming people can do it.

It was obvious that she followed Zhang Yanbing's words, her heart changed, and she reflected on her face, from the beginning of her apricot eyes were full of surprise, followed by anger, her eyes turned red instantly, but she soon calmed down and became very sad, sniffed, her mouth was also a little aggrieved, and finally her brows were tightly locked, her eyes were rolling, obviously hesitating.

In the end, all these expressions disappeared, and seeing that her face was like ice and snow melting, the corners of her mouth were raised, and the corners of her eyes were smiling, she obviously figured it out.

"What does this mean? It may be the sweet words between lovers, or talking about the boudoir, the woman's feelings are rich and delicate, and her personality is straightforward, all of which are directly reflected on her face, is there anything wrong?" Wang Jia, as a mutual friend of Zhang Yanbing and Xia Li, spared no effort to defend Xia Li.

"If it's really a sweet talk between lovers, or a private conversation, then as you say, an emotional and straightforward lady has a table that should appear the most, but it doesn't appear. Gao Jun said coldly: "That's shyness!"

Just like before, Gao Jun found that Qi Xinyue had signs of completely evolving into a queen, in order not to be favored in the future, and even become Li Lianying, Gao Jun immediately opened the * mode, which made her focus on life and light on career.

But as soon as he finished his little proposal, he was angrily reprimanded by Qi Xinyue with shame and annoyance, saying that he was thinking about crooked ways and wasting fire in vain.

This is the kind of love words between a man and a woman, even out-of-the-ordinary words, after touching the bottom line, a woman should react, especially a woman who likes you, no matter how strong she is and how independent she is, there will be a shy reaction first, but just now Xia Li's face changed again and again, but she was never shy.

Seeing that Wang Jia was about to open his mouth to argue, Gao Jun preemptively said: "Judging from Xia Li's reaction in just one minute in the picture just now, I think not only me, but many people present will think that Zhang Yanbing said something to her that touched her bottom line and made her angry, so she will have a starting performance."

It may be that she really likes Zhang Yanbing, or it may be that she is in her interests, and she finally compromised, so she had a sad and hesitant expression, and finally agreed with a smile.

And in my opinion, this is her motive for killing Zhang Yanbing!"

"Nonsense, I haven't heard of anyone who can see the motive for killing by looking at their expressions. "Wang Jia is naturally a hundred dissatisfied.

It doesn't matter if she accepts it or not, when she does, because Gao Jun spoke again: "Since there is a motive, let's talk about the second element, that is, the method of killing, which is actually complementary to the murder weapon."

Some people will first see the murder weapon and think of the way to kill, and some people will first simulate a safe and effective way to kill and then look for a suitable murder weapon.

And she is the former.

Based on the motive just now, it is certain that this is a case of impromptu murder of passion, and without adequate preparation, only ingenious methods can be used. ”

"Hah...... It's not useful at all. Wang Jia hurriedly interjected: "It's still just now, a tray with ten cups, ten people who want to drink, take it at will, there is no order, there is no specific cup, why would Zhang Yanbing take a poisonous cup?"

"It's very simple, because this was originally designed by Zhang Yanbing himself. Gao Jun said.

As soon as these words came out, the crowd was in an uproar again, could it be that Zhang Yanbing really wanted to commit suicide?

Gao Jun waited for them to discuss for a while, and then said: "Everyone saw it just now, Zhang Yanbing was carrying drugs to protect the liver and nourish the stomach, one is to show that he has a lot of entertainment in the wine bureau, and the other is that alcohol has harmed his body, and he was already a little drunk at the wine table just now, but today he is not only the convener, but he also wants to talk to Miss Qi on business while he is drinking, so he has to be patient."

Another point, there are also a lot of successful businessmen here, and there are a lot of socials on weekdays, everyone knows our wine table culture, the wine table is good to talk about, and if you drink too much, you will sign, this is the purpose of entertainment, but first of all, you must stay sober.

But at that time, Zhang Yanbing was already drunk, and he had to stay sober, but he also had to Miss Qi get drunk, so this scene happened......"

After Gao Jun finished speaking, he adjusted the progress bar of the video again, it happened to be Xia Li bartending, the technique was as exquisite as juggling, and everyone around was dazzled and dumbfounded.

Gao Jun pressed the pause button and said loudly: "Even if Xia Li is an excellent bartender, after all, today is one of us and a guest, there is really no reason for her to show up to help the fun." ”

Gao Jun's words have been recognized by many men at the scene, this is like our family inviting guests to dinner, eating and suddenly a little cold, although as the host to save the scene, but there is no reason to let his daughter-in-law come out to sing a song and dance to please the guests, it is too cheap.

"And I guess that Zhang Yanbing not only wants Xia Li to mix wine to help the fun, but the main purpose is to get Miss Qi drunk and keep himself sober. Gao Jun said: "It is not difficult to understand this, if all of you have become a family, the bride and groom who have held a wedding banquet know that during the wedding banquet, a couple will toast the relatives and friends present from table to table, some more than a dozen tables, some dozens of tables, even if a table and a bottle will be drunk."

In order to avoid getting drunk and making a fool of yourself, usually the best man and bridesmaid who follow behind will replace the white wine with Sprite and the beer with black tea.

Zhang Yanbing was thinking like this at that time, so he would let Xia Li come out to bartend!"

Speaking of which, people somewhat understood, and felt that what Gao Jun said was getting closer and closer to the truth, and this time even Wang Jia didn't speak, because she knew that Gao Jun was about to reveal the cause of Zhang Yanbing's death.

Suddenly let Xia Li show up to bartend, which also fell into the hands of Xia Li, who was full of murderous intent, and it was equivalent to creating an opportunity for her to kill. Gao Jun said loudly: "This killing game is only so ingenious, because when he took the cup at the end, there was only one poisonous cup, why would Zhang Yanbing take it?"

In fact, according to what I just said, I think everyone is also clear, Zhang Yanbing wants Miss Qi to get drunk, and he stays sober, how can he do it, just like the bride and groom use Sprite instead of liquor at the wedding!"

After speaking, Gao Jun opened the video again, and the picture was frozen when Zhang Yanbing was elated and reached out for the first time to take the wine glass.

Some people already have ideas in their hearts, and they have the courage to take a closer look, and the same is true of Director Wang, through Gao Jun's description and video footage, he realized that the most critical part of this technique is in this suspended picture.

It's just that everyone looks left and right and really can't see the clue, Gao Jun repeatedly pressed the pause start button, the picture is like moving frame by frame, and suddenly the sports committee exclaimed: "This liquor has ice cubes added to it!!"

After he reminded people, people looked again, and sure enough, when Zhang Yanbing picked up the wine glass, the wine in the cup was shaking, but it looked strange, not just the wine swaying slightly, if you look closely, there are ice cubes floating and floating, although it is a small piece, but it can still be seen under the high-definition camera.

"Let's take a look at the other glasses. Gao Jun pointed to the table and said, suddenly someone died, and the others didn't finish the wine.

Everyone finally discovered the ingenuity of this technique, no wonder Zhang Yanbing took the initiative to pick up the cup of poisonous wine, because only this glass of wine was mixed with ice cubes, which was different from the other glasses, which should also be the agreement between him and Xia Li.

Adding ice cubes to the liquor is equivalent to mixing water in the liquor, which will reduce the concentration of the liquor and make the taste cooler and easier to eat, so that Zhang Yanbing will get drunk later than others, or even not get drunk!"

The puzzle is finally solved!!

People suddenly realized that they had to admire the ingenuity of this technique, and what was even more ridiculous was that this was completely Zhang Yanbing's own grave, providing the murderer with the opportunity and method to kill himself.

When people looked at Xia Li again, they were either angry or scared in their eyes, and they had completely regarded her as a murderer.

Wang Jia, as her spokesperson, gritted her teeth to make the last resistance: "What's the big deal? It can be said that Xia Li was afraid that her boyfriend would get drunk, so she deliberately added ice cubes, and she was just kind."

What's more, as you said just now, there is another important factor that is the murder weapon, but you see, Xia Li is wearing a dress and a long skirt, and she doesn't even have a pocket on her body, she has been with us since she entered the door, and she only left for a while when she went to prepare the bartending utensils, but she didn't leave this hotel, since it was a passion killing, she would never prepare this bloody poison in advance, right?"

Wang Jia's rebuttal is really reasonable, especially when Gao Jun also said that this is a temporary murder of passion, so how did the poison come from?
