After the meeting ended, Su Ping asked Yan Zhongxin, Lao Wei, Song Ge, Lao Hai and Qi Yuan and others to stay.

Lao Wei probably guessed what Su Ping was going to ask, and when the people were finished, he lit a cigarette by himself, and said directly: "Team Su, we have carefully investigated the scene and determined that in addition to excluding the traces left by the victim himself and our investigation, there is only one set of footprints, which is Cai Pengcheng's." ”

After a pause, he added: "You have also seen that the scene has become like that, there is blood everywhere, even if it is a professional trace inspection like ours, laying a survey board, it is inevitable to leave a few traces at the scene, and they have to be sampled and excluded, not to mention the suspects." ”

Yan Zhongxin frowned and said: "But Cai Pengcheng died at noon on the 13th, five days ago, and the direct cause of death was mechanical suffocation caused by choking on water. ”

"That's right." Su Ping nodded and said, "The windows at the scene were only pushed open this morning, otherwise the surrounding residents must have smelled the stench for a long time." Cai Pengcheng is dead, and there is definitely no way to go back to the scene to open the window, so who is the one who opened the window? What is the purpose? ”

Lao Wei spread his hands and said, "I also know that our trace inspection is very important, but I really didn't find any suspicious clues...... Well, I'll take someone back to the scene to search for it later, and see if there's any trace that I've missed. ”

"Hmm." Su Ping nodded lightly: "Try to find out, even if the murderer is dead, we have to close the case beautifully, and if there are other people involved, we must not let it go." ”

"Don't worry, I know." Old Wei said.

At this time, Qi Yuan hesitated for a moment and asked, "Could someone have pushed open the window but not entered?" ”

"Push open the window and won't go in?" Su Ping pursed his lips and rolled his eyes: "Then ...... him"

As soon as he finished speaking, he was stunned for a moment, reacted, and immediately asked: "Wait, you mean, a thief planned to enter through the window, but just pushed the window open, noticed that something was wrong, and slipped away?" ”

Qi Yuan nodded: "That's what I think." ”

Brother Song pinched his chin, shook his head and said: "No, these days, there have been fewer and fewer burglars, everyone doesn't have much cash in their hands, and electrical appliances such as mobile phones are not worth a few dollars, and the sentence for theft is actually quite heavy, and the cost of crime is much higher than the proceeds of crime, so it stands to reason that ......"

"It's hard to say." Su Ping shook his head: "Just this year, there have been many burglary crimes, because of the impact of the epidemic in the early years, the cash utilization rate has been greatly reduced, and robbery and pickpocketing crimes have been greatly reduced, but other theft crimes, such as burglary, have been relatively improved." ”

"Yes, that's right." Lao Hai also said: "Especially at the beginning of the year, the price of gold has risen one after another, and since then it has remained high, many people have begun to invest in gold, most of which are virtual gold, but there are also a lot of physical gold, and the gold jewelry market is also quite hot." ”

Fang Chang answered: "Indeed, and the gold recycling, to be honest, the supervision is not enough, the recycling business of tens of thousands of yuan does not need an invoice at all, and the purity and weight can be directly traded on the spot."

There was a previous case where the young man owed an online loan and couldn't repay it, so he stole the gold jewelry from his parents' marriage and sold it for 50,000 yuan. ”

Brother Song thought for a moment and said, "If that's the case, you can inquire if Lu Zhaoshan's family has recently purchased a large amount of gold jewelry and been seen by someone with a heart." ”

"Bought it." At this time, Xiao Gao said: "I just mentioned this, so I asked my colleague to check the victim's mobile phone in detail, and found that the deceased had purchased a total of more than 330,000 yuan of investment gold in the past six months." ”

"Three hundred thousand gold." Su Ping's eyes narrowed: "This has to let people know that there are ghosts if they don't suffer from thieves." ”

"Then I'll go and investigate tomorrow." Brother Song said: "If anyone knows that he bought a lot of gold......

"Hmm." Su Ping didn't wait for him to finish, he nodded lightly.

Then he looked at Lao Wei, frowned and asked, "Lao Wei, didn't you find any property or anything at the scene?" ”

"Yes, there are a few gold jewelry on the scene, all in the wardrobe and bedside table, with a total weight of more than 130 grams and a total value of about 50,000 yuan." Lao Wei said: "Of course, it is estimated that it will not sell so much, and it would be good if the jewelry recycling could sell for 351 grams."

I also wrote these into the scene investigation report, there is no trace of the bedroom being rummaged, the property has not been lost, and the possibility of burglary and robbery escalating to homicide has been ruled out, I told the Xun team before. ”

"Lao Su didn't tell me, ignored it?" Su Ping asked rhetorically, and then raised his eyebrows and asked, "No, it's only 50,000?" ”

"Only fifty thousand."

"That," Xiao Gao said, "the suspect bought a gold fund, the T+1 kind, not physical gold." ”

Su Ping pursed his lips.

Qi Yuan said: "This shouldn't be important - if Lu Zhaoshan bragged and said to the outside world that he had bought more than 300,000 pieces of gold, the first reaction of those people he befriended was probably physical gold." Of course, it is not excluded that some people who play with funds know that he is talking about physical gold. ”

Su Ping looked at Brother Song, and Brother Song immediately said, "I'll ask Ming'er clearly." ”

"Hmm." Su Ping responded, thought about it, and said, "Another...... There is also a question about the place where Cai Pengcheng committed suicide. If he chose to commit suicide in the cemetery, it would be understandable, why did he run to Liufeng Mountain to jump off the cliff? ”

"I've been thinking about this question since you just asked it." Qi Yuan answered.

"Oh?" Su Ping raised his eyebrows, looked at it with some expectation, and said, "You thought of it." ”

"I don't understand." Qi Yuan said: "This is not logical, just like what you said in the Su team, he wants to commit suicide in the cemetery, or return to the car to commit suicide after worshipping his deceased wife, or return to the rental house and can't think of committing suicide or even committing suicide in the freezer, it makes sense, go to Liufeng Mountain and jump off the cliff?" What about Gaha? ”

"Unless, Liufeng Mountain has some special meaning for this couple, such as the place where love begins and so on." Fang Chang said.

Su Ping's thick eyebrows trembled, and he seemed to feel a little numb.

After a while, he shook his head and said: "Regarding this, it is still the sentence before the meeting, try to check it as much as possible, it is best to find out the suspicious points, and there is no way to figure it out, as long as it is determined that Cai Pengcheng does not have other accomplices, there are no other insiders in this case, and Cai Pengcheng's death has nothing to do with anyone else." ”

"Hmm." Brother Song responded, and then said: "Actually, there are a lot of doubts on the scene, such as why Cai Pengcheng put the corpses neatly tied. But overall, it's not a big problem, maybe it's some kind of revenge. ”

Lao Hai answered: "As for why it took a lot of trouble to go in and out, it is easy to explain."

If Cai Pengcheng had already sprouted the will to live and die, in fact, he didn't care about what was exposed or not, the goal of killing all of Lu Zhaoshan's family had already been achieved, and it didn't matter if he was arrested, as long as he could do more, it would be 'making money'. ”

Qi Yuan asked again: "Then why seal the scene?" Since he didn't care, even if for some special purpose he wanted to dismember the deceased and neatly stack it into the appearance of 'stuffed tofu', there was no need to go to great lengths to seal the scene, right? ”

Su Ping rolled his eyes: "God TM stuffed tofu, you said that you were greedy, and you will eat together?" ”

"Well, that's how Team Xun described it, I think it's quite appropriate." Qi Yuan coughed dryly.

At this time, everyone was a little embarrassed, and then they came back to their senses, and their eyes fell on Lao Hai.

Lao Hai is a psychology background, and he may be able to guess Lu Zhaoshan's purpose.

"Perha......ps," Lao Hai said tentatively, "He wants mosquitoes, rats and ants to eat the victim's corpse little by little, so as to vent his anger?" ”

Yan Zhongxin's eyes lit up suddenly, and he said:

"Yes! Mosquito! Don't you think that there are too many flies on the scene? After all, the scene has been completely sealed by Cai Pengcheng, and it is unlikely that a few days will last so long just by the indoors flies, even if a large number of flies flew in after the window was opened that morning, it should not be so much. ”

After a pause, he said: "There is also that meal, that meal also has a problem, it may contain a large number of fly maggots, after bringing it to the scene, he directly deducted the meal, let the fly maggots gnaw on the corpse, and then the fly maggots turned into flies, and new fly maggots multiplied again......

Speaking of this, he opened his notebook and looked at it twice, thought for a moment, and then continued: "With the current temperature and humidity, flies can turn from eggs to maggots, and it only takes seven days at the shortest, of which the eggshell stage is twenty-four hours, the larval stage is three days, and the pupal stage is three days.

And if the maggots he brought with him were close to pupating, they could develop into flies in three to four days. Moreover, the autopsy of the deceased's dismemberment is presumed to be the twelfth, six days ago, which is enough to turn the maggots into flies, which would explain why there were so many flies at the scene! ”

Fang Chang pursed his lips, his face showed disgust, and said, "Let the maggots eat all the corpses?" That's ......."

Qi Yuan said: "I only pity Fang Hui and Lu Chuan, the mother and son, not to mention the domestic violence suffered by Lu Anran all the year round, and finally took a life to bury those three scumbags." ”

Brother Song pursed his lips, sighed lightly, shook his head and said: "Indeed, judging from the results of the current visit, I have not found any shady scenes about Fang Hui, as a kindergarten teacher, she is quite popular with children and their parents, and Lu Chuan is also quite well-behaved and sensible......"

Su Ping shook his head and said, "Okay, let's dismiss the meeting, go out for a bite to eat, and then disband, what should I do, I still have work tomorrow, and it is estimated that there will be a lot of work to close up this case." ”

Several people snorted and got up one after another.

Lao Wei said: "You guys go to eat, I'll go back to the scene on an empty stomach, focus on surveying the exterior walls and exterior glass of the site, and see if I can find any clues." ”

Qi Yuan thought for a while and asked, "By the way, Director Wei, the window at the scene ...... If it is closed and locked, are you sure it can be opened from the outside? ”

Lao Wei was stunned for a moment, and then said, "Wait, I'll take a look at the photo." ”

So the few people who were going to leave stood still again and looked at Lao Wei quietly.

After a while, Lao Wei smiled: "No problem, because of the sealing ring, the window can't be locked, but after pressing hard, the window is difficult to open due to the air pressure, and it is estimated that the suspect also made a lot of effort to open it." ”

Qi Yuan bowed slightly.

Lao Wei said: "Okay, I'll go over and have a look first, and I'll call you if I find it." ”

Su Ping raised his eyebrows: "Are you sure you don't want to eat something first?" ”

"Come on." Lao Wei rolled his eyes: "The smell of the scene, it must not have dissipated until now, you can't spit it out all if you have to eat?" ”

Qi Yuan chuckled: "Then, Director Wei is not afraid that he will have no appetite for it?" ”

"That's not going to happen." Lao Wei waved his hand: "After doing the mark inspection for so many years, I have long been used to it, as long as the nose adapts to the smell inside, go back and wash your hands and change your clothes, and still eat it." ”

Su Ping patted him on the shoulder, said hard work, waved his hand, and led the big guy to eat.

……

In the evening, Lao Wei brought good news - on the outside of the window, several fingerprints were extracted, which were probably left by the suspect who pushed the window open.

He judged that the suspect should be wearing gloves at the time, but it was not good to push the window with gloves, so he had to take off the gloves, and then he smelled a strong stench, and then opened the curtain to see, he was startled, and almost rolled out of the window, knowing that the dead person was dead, he left in a hurry, and even forgot to erase the fingerprints left behind.

Su Ping asked him to immediately extract his fingerprints and compare them with the fingerprint database to find out the suspect - at this time, the fingerprint database was basically complete, except for a very few people, all of them were registered in the database, and collecting fingerprints meant that the suspect was not far away.

At the same time, the next day, Cai Pengcheng's parents came to the criminal investigation detachment, and then the two elders cried into tears.

Finally stabilized their emotions, Su Ping invited them to his office, handed them water, and chatted with them.

They don't know much about the current situation of Cai Pengcheng and Lu Qing, although they live in the same city.

After all, Cai Pengcheng always reports good news and not bad news, but I only know that shortly after Lu Qing died in a car accident a year ago, Lu Zhaoshan asked Cai Pengcheng for compensation, and the two families had a little awkward quarrel at that time, and then Cai Pengcheng decided to deal with the matter with full authority and gave Lu Zhaoshan the money.

Su Ping sighed lightly, and suddenly understood that the reason why Cai Pengcheng gave in again and again was probably because he was worried that his daughter and parents would be harmed, right?

"Peng Cheng also said that he wanted to sell his house and car and go to other places to develop." Cai's mother's tears fell again: "I don't agree with it, but I also respect his choice......"

Cai's father shook his head lightly and sighed: "In July and August, he transferred Cen Cen to a school near our residence, saying that it was not good to work hard with the children, let us help bring it, the two of us discussed it and agreed, Cen Cen has always been very well-behaved, never made trouble, only occasionally asked Dad when he would come back." ”

Cai's mother's tears fell faster, crying and said, "Where would we have thought that he didn't leave, and he was still thinking about this murder...... Why is he so stupid! For the sake of such a rotten family, committing such a thing, and committing suicide myself, is it worth it? ”
