After a pause, Lao Liu said: "If one person takes the initiative to testify for the other, unless the relationship between these two people is extraordinary, or the relationship between these two people is close, that person will do this." If this is not the premise, what must be the premise for a person to take the initiative to testify for an irrelevant person? ”

"In addition to pushing the boat along the river and doing good deeds and keeping favors, is there still the biggest premise, that is, the person who takes the initiative to testify must have sufficient evidence, or he must have full certainty, so that he has enough courage and confidence to do so? Especially Wang Kang, if he is not completely sure, would he dare to take the initiative to do this? ”

Then, Lao Liu pointed to the end of the transcript and continued: "Su Chao asked Wang Kang, if there is anything to add, according to our understanding and the intention of the interrogator, it should be asking Wang Kang to prove that he is not a murderer, and whether there is any strong evidence that needs to be supplemented witness testimony, etc., but Wang Kang took the initiative to testify to Shi Jun. ”

Of course, this point did not arouse Su Chao's suspicion at that time. Because Wang Kang spoke stumbling and trembling throughout the conversation. Therefore, Su Chao asked Wang Kang again, if there is anything else that needs to be added. ”

"People like Wang Kang, when they defend themselves, even if what they say is true, they will stammer, for fear that others will not believe it. But he took the initiative to jump out to testify for Shi Jun, and we don't care whether it is convenient to push the boat to leave favors, but what can be basically determined is that Wang Kang should be very sure that Shi Jun is not the murderer. ”

Lao Liu continued to talk eloquently: "Although Wang Kang is introverted, timid and cowardly, he is a very smart person. In his previous testimony, it was pointed out that Shi Jun had a conflict with Zhou Xiaolu. Therefore, he would definitely think that the police would probably suspect and investigate Shi Jun because of this. In this case, he still mustered up the courage to jump out and take the initiative to testify for Shi Jun, does this further show that Wang Kang is very sure that Shi Jun is not a murderer? ”

The two pondered carefully for a moment, and had to think that what Lao Liu said was reasonable.

Lao Liu continued: "Let's first take the premise that Wang Kang is very sure that Shi Jun is not the murderer, and then let's take a look at Wang Kang's confession. He only went online to play games on the night of July 2, which means that he only saw Shi Jun online that night, so during the day on July 2, what Shi Jun was doing, Wang Kang should not know. ”

The time of Zhou Xiaolu's murder was on July 2, but at the specific time point, because the body had been exposed to the sun and rain for 11 consecutive days, the autopsy report could not accurately judge, that is to say, the precise time of Zhou Xiaolu's murder was not even known to the police. In other words, no one knows whether Zhou Xiaolu was killed during the day or at night on July 2. ”

"But Wang Kang judged that Shi Jun was not a murderer just because he saw Shi Jun's game account online at night, so he bravely took the initiative to testify for her, is this unreasonable?"

"In other words, the reason why Wang Kang is very sure that Shi Jun is not the murderer is not because he saw Shi Jun's game account online that night, but because he has other evidence, which makes him convinced that Shi Jun is not the murderer." Wang Xing said, "There is another possibility, Wang Kang is very likely to know who the real murderer is, but he did not tell the police, that is, it is very likely that he is the real murderer." ”

Then, Wang Xing closed his eyes again, as if he didn't dare to believe everything in front of him, and said, "Really let you Li team ...... Got it right? ”

"It's not as divine as you think, and he sometimes goes wrong." Lao Liu said, "He just imagined all the possibilities, and then verified them one by one from high to low according to the size of the probabilities." Sometimes they use stupid methods that seem simple, but they work very well. ”

Ouyang opened the curtains of Wang Xing's office, only to find that it was already night. Before they knew it, they had watched the transcripts and videos for a whole day.

Outside, it was drizzling at some point. The drizzle fell silently, like silver filaments spit out by countless silkworm girls. Thousands of filaments, rippling in mid-air, seem to cover the city with a light veil of mist. The colorful neon lights, car lights and thousands of lights add a lot of haze to this light veil.

"These are all analyses and speculations, and there is no substantial evidence." Ouyang glanced at Wang Xing and said, "Old Liu, why don't you ...... Let's leave this case alone, and according to Team Li's arrangement, continue to follow Wang Kang's traces in Shashi to collect other clues related to him? ”

Lao Liu put the case file back on the table and said very dissatisfied: "Such an important discovery, even if there is no evidence, it can't be regarded as not knowing anything." How many of all the cases solved started with no evidence? If there is evidence to start the investigation, then few cases can be solved. ”

Ouyang glanced at Lao Liu and said, "I understand what you mean." But we can't just rely on a few guesses to say that we want to start the investigation process of such an unsolved case, right? This...... Aren't you slapping people in the face......"

Wang Xing stretched, yawned loudly, and said, "Two, stop acting, I know what you mean." It would be much better for me to bring up this case than for you to point out the negligence of the investigation back then. However, this matter really has to be put aside for the time being, and it would be more appropriate for my leader to raise it with the detachment. My leader...... I went out to the police, and I should be back in the next few days. ”

Seeing Ouyang and Lao Liu looking at him suspiciously, obviously suspecting him of shirking the situation, Wang Xing took a few steps forward, pointed to the case file on the table, and said, "Yang Feng, who investigated this case back then, is my current leader. As for Su Chao, he has retired. ”

The two suddenly realized. In this unsolved case, there is indeed no more appropriate case than the investigators who took the initiative to restart the investigation.

Immediately, Su Chao made another difficulty, saying: "Even if Wang Kang is the real murderer, but now he is in a vegetative state, judging from the dossier, there are basically no people who had a deep relationship with him back then, or know more about him, and this case has passed for so long...... It's hard......"

After a pause, he said, "Let's go get something to eat first." ”

Then, Wang Xing pointed out the window and said, "It's not far from Bonan University, and there's a snack street there." I'll do the East tonight. If the two police officers are interested, they can also stop by to see if Shang Biao is still opening a bubble tea shop there. ”

There seems to be a snack street near every university. Such food streets are often hidden in inconspicuous corners, and at night, they can be crowded with people and noisy.

Students walked in groups with umbrellas, lingering in front of various food stalls. Whether it's roasted gluten from Mongolia, or alpine potatoes from Shennongjia, or rose jelly from Sichuan and roasted oysters from Fujian, in short, only you can't think of it, and you can't eat it.

The store of the bubble tea shop opened by Shang Biao back then has long been replaced by a "Lanzhou ramen". The three of them ate a bowl of noodles inside, and when they inquired, the shopkeeper really had nothing to do with Shang Biao.

The light rain stopped, and the crowds on the street increased.

Wang Xing led the two of them to eat and stroll, chatting while shopping, and unconsciously arrived at the gate of Bonan University.

"It's raining today, and the small bamboo lake in the back mountain will fog again, accompany me to take a few photos?"

A pair of male and female students walking together walked in front, and it seemed that they should be in a romantic relationship. One of the female students said.

"Light rain, bamboo forests, white mist, calm as a mirror. It had to be done during the day, and now you can't shoot anything at night. Moreover, I heard that people have died on the shore of Xiaozhu Lake, and the murderer has not been found until now. The boy said.

"You're just lazy, you don't want to go with me, and you make up stories to scare me." The girl said.

"Heaven and earth conscience, what I say is true. If there is half a lie, I will not lift it for the rest of my life......"

"Are you cursing yourself, or are you cursing me? Hurry up and pew it out. ”

After the boy's "hehe" smirk, he snorted a few times, and then said: "This matter can be searched on the Internet, and it has been included in the top ten unsolved cases." It also said that the person who died was also a student of our school, and he was still the school flower of the year. ”

"It turned out to be a school flower...... No wonder you're so interested. ”

"I'm not, I don't, don't talk nonsense. I just want to tell you, that place, it's better to go less, especially at night, it's still raining and cloudy...... Besides, there is a lewd old man living in the pavilion, and I heard that he specializes in stalking female students......"

"Okay, okay, don't chirp, if you don't go, you won't go......"

At this time, the pair of male and female students glanced back, only to notice that they were followed by three big men.

Seeing the three of them staring at themselves, they couldn't help but speed up their pace, and soon walked into the campus and disappeared.

"It seems that they are treating us as bad people." Ouyang muttered.

"At night, following behind people and staring at people, everyone will think that they have met a bad person." Lao Liu said.

"We also listened to them talk about the case back then, so we followed all the way, and the devil knew that they would treat us as stalkers and molest criminals." Wang Xing said, "Since we are here, why don't we also go to the scene of the crime back then?" ”

Judging from the case file, the small lake in the back mountain of Bonan University should have been a barren land, but now from what the two students said, the small lake and its surroundings were repaired and ordered, not only planted bamboo forests, built pavilions, but also named the lake "Little Bamboo Lake".

Wanting to make a new discovery at the crime scene of the year is tantamount to a fool's dream.

"Let's go around and see if the 'lewd old man' that the two students said is a homeless man or an molester." Lao Liu said.

Wen Tao's appeal has been decided.
