The reason why Ma Wenlong's case became an unsolved case back then was that the murderer did not leave any clues, and more because the murderer's motive for killing could not be found.

According to the files of the Special Investigation Bureau, whether it is Ma Wenlong's family or Ma Wenlong himself, all assets have not suffered any loss, even when Ma Wenlong finally emigrated abroad, his property was also sold and liquidated and all taken away, which also made the investigators at that time a headache.

"What do you think the murderer's motive for killing?" Qu Liuqiao recalled the contents of the file and couldn't help but ask in a deep voice.

Tang Tian didn't answer this question immediately, his gaze swept over the corpse repeatedly, he wanted to light a cigarette, but suddenly remembered that he couldn't smoke at the scene of death, and couldn't help but smile bitterly and shook his head, "I have a few guesses, there may be three motives for the killing, first, killing people and killing people, because Deputy Captain Kong once said that their police officers carried out control at Liang Yueying's house, which shows that Liang Yueying's own foundation is not very clean! Second, the distribution of stolen goods is uneven, and Liang Yueying is very likely to take the proceeds that should not be taken in the process of committing the crime." As for the third, and I think it's the most likely, is that the drunkard doesn't mean to drink!"

"The drunkard doesn't mean to drink?" Kong Sen, who had been silent, suddenly spoke, "Comrade Xiao Tang, can you tell me in detail?"

"It's hard to say now!, but my intuition tells me that this Liang Yueying will definitely not be the last person to die, and I suggest that Wang Yankai's other family members be monitored and protected immediately, especially his children and parents, or other relatives who are close to him!" Tang Tian felt that the Meridian Society should replicate Ma Wenlong's case in Jinyang City, so that Wang Yankai's family would be monitored and protected in advance, and he might be able to arrest him when the Meridian Association started to kidnap people.

After hearing Tang Tian's words, Kong Sen had some guesses in his heart. As an old criminal policeman who has been struggling in the front-line post for more than 20 years, at this moment, his intuition tells him that he will face a great challenge!

"Xiao Wang, you go back to the team and take the second group, and protect Wang Yankai's old mother first!" Kong Sen said this to the young police officer standing at the door, and turned his head to look at Tang Tian, "According to our investigation, Wang Yankai's father has died, and his mother lives in a unit in the city center, but the most troublesome thing is that his daughter has married away to other cities, and we have no ability to protect her for the time being! ”

Tang Tian nodded, there are few people in the Special Investigation Bureau, this matter is still left to Kong Sen to arrange reliable, and there is no need to waste his energy on fixed-point monitoring.

After the investigation of the scene, Kong Sen also immediately arranged for an autopsy on Liang Yueying's body, in his opinion, Liang Yueying's death was very strange, obviously drowning, but there were no symptoms of most drowning corpses, maybe figuring out her specific cause of death, this case will be solved?

When the autopsy report came out, Kong Sen's face became very ugly, and it was clearly written on the autopsy report that the cause of death was choking and suffocation in the lungs, and the time of death could not be accurately calculated, because the skin of the corpse was intact, although there were corpse spots, the time of death could be estimated to be less than four hours according to the corpse spots, which was absolutely impossible!

Compared with the autopsy report, the results of sampling and testing of cells on the body surface of the corpse have made a small gain.

According to the results of this test, the water used to soak the body was not normal river or lake water, because of the amount of water in nature

All contain bacteria, these bacteria will accelerate the decay of the corpse, but Liang Yueying's corpse has no obvious signs of decay, and the smell of the corpse is more caused by the accumulation of gas in the corpse.

"Could it be pure water or something?" Tang Tian took the autopsy report from Kong Sen's hand, and after reading it carefully, he had some guesses, "And it's pure water at zero degrees!"

Zero degrees will not freeze, naturally will not destroy the cell tissue of the corpse, but the same zero degree also inhibits the breeding and reproduction of bacteria, so that the time of death can not be determined during the autopsy, plus the corpse is abnormally swollen, enough to pretend to be a ghost and disturb the audio-visual!

"It is impossible for them not to know that the police are already controlling Liang Yueying, and at this juncture, they have to go to great lengths to kill Liang Yueying, and even carry out special treatment on her body, and move it to the bedroom of the villa, creating the illusion of death in the secret room to bluff people, which shows that they want to use Liang Yueying's death to mislead or disrupt our judgment!" Tang Tian said this, sneering and throwing aside the test report in his hand, " Let's change the direction of investigation, let's not care about how they put the body back in the villa bedroom, and why Liang Yueying's body is so weird, let's stare at Wang Yankai and his family to death, and put a brake on the quiet!"

Kong Sen very much agreed with Tang Tian's proposal, and immediately instructed the police officers who were monitoring Wang Yankai's family to go into the dark, be vigilant and be ready to deal with emergencies at any time, wait for the murderer to strike again, and strive for a yellow bird to capture him in one fell swoop.

On the third day after Liang Yueying's death, Wang Yankai's daughter Wang Yanan returned to Jinyang City, because Wang Yankai's mood fluctuated violently, and Liang Yueying's funeral was completely handled by Wang Yanan.

On the sixteenth day after Liang Yueying's death, Xiang Yu called a meeting of everyone, and he felt that it was not a way to continue to wait like this.

"Sixteen days have passed since Liang Yueying's body was discovered, and the monitoring on Deputy Captain Kong's side has never been found, should we change the direction of investigation?" Xiang Yu sat at his desk, his ashtray full of cigarette butts.

Tang Tian was also very distressed, and he couldn't understand why the Meridian Society didn't continue to attack Wang Yankai's family, could it be that he had made a mistake in judgment? Liang Yueying's death was not the same as the Ma Wenlong case back then?

"The problem is that we don't have any other direction of investigation!" Qu Liuwan smiled wryly and spread his hands, "In the past half a month, we have checked all the surveillance videos near Wang Yankai's villa, and we have found no trace of the corpse thrower, and we have also asked the police officer who was responsible for monitoring the villa that day, because it was confirmed that Liang Yueying was not in the villa, so they only monitored the door of the villa, if it weren't for the fact that some police officers found that the curtains in the bedroom had changed slightly, even the body could not be found!"

"What's more, there are no traces left at the scene, only the fingerprints of Liang Yueying and Wang Yankai are in the bedroom, and the possibility of continuing the investigation according to the results of the on-site investigation is almost zero!" Jiang Yongsheng also had a headache, he was not good at case analysis, and he was driven crazy every day when he followed Tang Tian to the scene.

Xiang Yu looked at the group of people with sad faces in front of him, and his brows furrowed even tighter, "It's certain that there will be difficulties, if it is so easy to investigate, Ma Wenlong's case back then would not have been shelved until now!

If there is a difficulty, just look at the difficulty and don't think of a way!"

Xu Zhiwei heard this, and almost blurted out a sentence of standing and talking without back pain, his main job in the past few days is to investigate the records related to Ma Wenlong, screening on the computer screen all day long, and the degree of myopia has increased a lot, but those materials are all messy nonsense, and most of the information about Ma Wenlong after immigrating is just a few words.

Seeing that everyone was downcast, Xiang Yu directly ordered Tang Tian's general, "Tang Tian, tell me if you have found anything in the past few days?"

"I didn't find it, but I had a belly of fire and wanted to vent! The account books and import and export records of Sanxin Seafood Processing Factory were about to be rotted by me, and I went to find Wang Yankai, but I didn't find anything!" Tang Tian shrugged his shoulders, if you want to say who is the most depressed recently, it is definitely himself! I was thinking about digging deeper from Wang Yankai, but I didn't expect that Wang Yankai was like a different person, since Liang Yueying's death, the whole person has languished a lot, no matter what Tang Tian said to him, he was silent, and he could stare at the wall alone for a whole day, "Now I can only wait! If the meridian meeting no longer does anything to Wang Yankai's family, we won't get new clues, and the random investigation can only mess up!"

Xiang Yu was silent after hearing this, he naturally knew this truth very well, but the problem is that it is no better now than in Angang City! If this is no problem in how to investigate on his own territory, there has been no progress in cooperating with the Jinyang City Criminal Police Team to investigate the case for half a month, and the Jinyang City Bureau has already been a little dissatisfied with this, thinking that the investigation of the Special Investigation Bureau is completely meaningless, and it has interfered with the normal work of the Jinyang City Criminal Police Team. For this reason, the deputy director of Chang called twice to urge.

In the end, Xiang Yu saw that everyone was really right, so he simply announced the dismissal of the meeting, he thought it was necessary to let the Jinyang Municipal Bureau realize the degree of harm of the Meridian Meeting, and was ready to make a phone call to Deputy Director Chang to apply for sharing some information about the Meridian Meeting with the Jinyang Municipal Bureau.

After the meeting ended, Qu Liuwan found Tang Tian, who was sitting in the car smoking a cigarette, and saw that he was in a very low mood, and wanted to comfort him, but the mobile phone rang, and it was still an unfamiliar number.

After Qu Liuqiao connected the phone, no one spoke for a long time, so she had to take the lead in asking, "Hello, who is it?"

"Is it Officer Qu? I, I'm Wang Yanan!" Wang Yanan's slightly hesitant voice came from the other end of the phone, "I'm sorry to interrupt, I've found some problems recently, but I don't know where to start for a while, if you have time, can you come to my house? Let's meet and talk?"

"You wait for me at home, you can arrive in about twenty minutes!" Qu Liuqiao said, hanging up the phone and turning his head to look at Tang Tian, "Go to Wang Yankai's unit in the city center, his daughter wants to talk to us!"

"Wang Yankai's daughter, that Wang Yanan?" Tang Tian immediately came to his senses, during the previous routine inquiry, this Wang Yanan's emotions were very excited, so the result of the inquiry was almost nothing. Now that this Wang Yanan took the initiative to contact Qu Liuqiao, he must have discovered some clues, right? Thinking of this, Tang Tian hurriedly started the vehicle and drove towards Wang Yankai's house in the center of the city.

When Tang Tian and the others arrived, Wang Yanan had been waiting for a long time, and there were still a few ledgers on the table in front of her.

Beckoning Tang Tian and Qu Liuwan to sit down, Wang Yanan's face was slightly bitter, "I'm sorry two, when you asked me about the situation before, because of your emotional instability and the fact that you were handling your mother's funeral, you didn't have time to communicate too much!"
