Qi Yuan couldn't beat them, and finally obediently took a detour and walked for more than ten minutes before reaching the waterfall.

This place is inaccessible, and the clues left by Cai Pengcheng should still be there. And if the clue is destroyed, it means that there were still people at the scene when Cai Pengcheng fell off the cliff, and Cai Pengcheng was probably pushed down the waterfall by that person.

But......

Lao Wei quickly surveyed the scene, shook his head and said: "There are only footprints left by Cai Pengcheng at the scene, and the sole pattern of the footprints is consistent with the pattern of the scene of the Anhe Village extermination case."

In addition, Cai Pengcheng's footprints were also found on the edge of the cliff, and there were a few scratches and kicking marks in the footprints. ”

After a pause, he raised his head again and said in a deep voice, "In other words...... He committed suicide. ”

Fang Chang frowned: "What kind of thing is this, Cai Pengcheng killed people, destroyed people, and then came here to commit suicide?" Martyrdom? Gotcha, the case is solved, let's ......"

Su Ping glared at him, he immediately shrunk his neck, turned his head sideways and whistled.

But Su Ping kept glaring at him, he blew twice, then smiled again, coughed dryly for a moment, and said: "Just kidding, let's confirm that the murderer of the murder case is indeed Cai Pengcheng, and we have to determine Cai Pengcheng's motive for committing the crime and the reason for suicide, how can it be so easy, hehe, hehe." ”

Su Ping slowly retracted his gaze.

Then, he looked at Lao Wei again: "I'm sure Cai Pengcheng committed suicide, rule out other possibilities, right?" ”

"Hmm." Lao Wei nodded and said: "You have also seen at the scene, there is a lot of sand and dust, if someone else approaches, it is unlikely to completely erase their traces, and leave Cai Pengcheng alone."

Since there is no trace of others, it can basically rule out the possibility of his killing, which is nothing more than an accident or suicide, and doing a standing long jump on the edge of the cliff is obviously suicide! ”

Qi Yuan pinched his chin, thoughtfully, and retorted: "Can ...... Didn't it rain on Liufeng Mountain a few days ago? Why are these footprints still intact? ”

"It's raining." Lao Wei said: "The three-dimensional footprints left on the scene are that after the sediment is wet, someone steps on it, leaving a clear three-dimensional footprint, and then the sediment is evaporated, and the footprints become a natural suggestion model, which is easy to extract and identify." ”

"Oh?" Qi Yuan blinked and asked, "In other words, it was after the last rain that Cai Pengcheng committed suicide by jumping off a cliff?" ”

Lao Wei nodded.

Su Ping immediately asked, "When was the last rain?" ”

"Not sure, check it when there is a signal." Lao Wei said: "But it should have been four or five days ago, just like Director Yan said, without four or five days, even if it is high temperature and humidity, it is difficult to form a corrupt giant." ”

Qi Yuan looked down at the stream, frowned, and said, "After four or five days, the flow of water in this stream is still so large." ”

"Actually, it's dropped a lot." Lao Wei said, and then stretched out his hand: "Look at the change in the water level, it's actually obvious ......."

"I won't look at it." Qi Yuan shook his head.

Lao Wei: ......

"Alright." Su Ping waved his hand and said, "Since it is clear, and other possibilities have been ruled out...... Wrap it up, don't waste time here.

In the next investigation, we have to adjust our thinking, maybe we have to focus on Cai Pengcheng. By the way, does Cai Pengcheng have children? I remember Song saying it, but I don't have any specific impressions. ”

"Yes." Qi Yuan said: "I have a daughter named Cai Qin, who is just nine years old this year. ”

"Nine-year-old ......" Fang Chang turned his head away, pursed his lips, and couldn't help but say, "It's only nine years old...... How can she live in the future? ”

Su Ping shook his head lightly, didn't say anything more, waved his hand and said, "Shut it up." ”

……

At night, the group was pulled back to the detachment with Cai Pengcheng's body.

On the way, Lao Wei checked and found that the latest rainfall in Liufeng Mountain was in the early morning of the 13th, and the rain stopped at about three o'clock, and it has been five and a half days since then.

Then Su Ping convened a meeting of the criminal police.

Brother Song got up first and said, "Team Su, in fact, I have found it until now...... The facts of the case are basically clear, and I can basically conclude that Cai Pengcheng killed and dismembered Lu Zhaoshan's family of five, and then drove to He Cuishan Cemetery, and after paying homage to his deceased wife, he went to Liufeng Mountain to commit suicide. ”

Su Ping raised his eyebrows and asked, "What about the motive for the crime?" Is it really for the money? ”

"You can say yes, you can say no." Brother Song sighed and said: "Cai Pengcheng and his friends complained about this matter at the wine table, and the direct reason was indeed because of money, because of the compensation for Cai Pengcheng's deceased wife. ”

Su Ping raised his chin and motioned for him to continue.

Brother Song continued: "Last year, Lu Qing was compensated 1.2 million yuan, and after her parents cried a few times, they asked Cai Pengcheng for money.

At that time, Cai Pengcheng didn't think too much, thinking that Lu Qing was also their daughter after all, so he gave them 600,000.

But they still didn't give up, feeling that Cai Pengcheng was just marrying Lu Qing, but they were Lu Qing's blood relatives, and it was not easy to pull them since they were children, and half of the compensation was not enough, so they had to add money. ”

Qi Yuan frowned.

Hearing this, he could already roughly guess the follow-up.

Sure enough, I heard Brother Song continue: "Cai Pengcheng was a little cold, but he didn't want to have more disputes with Lu Zhaoshan and them, after all, they were Lu Qing's relatives, so Cai Pengcheng gave an extra 400,000 yuan, and he only kept 200,000 yuan."

At the same time, Cai Pengcheng claimed to his friends that he wanted to continue to support Lu Qing's parents on behalf of Lu Qing after her death, but their behavior really made Cai Pengcheng's heart cold, and he decided to stay away from this family, leave the city, start over, and sell his house, car, and ......"

Su Ping's eyes narrowed and asked, "And then?" ”

"Lu Zhaoshan and his son came over like flies that smelled." Brother Song pursed his lips and sighed lightly: "They said that the house and car were the joint property of Cai Pengcheng and Lu Qing, why did he sell them, and criticized Cai Pengcheng for this."

After arguing for a while, they finally showed their feet, saying that since the house and car are common property, there should be half of Lu Qing, Lu Qing is dead, they have the right to inherit Lu Qing's inheritance, and ask for Lu Qing's half to be given to them. ”

Su Ping rolled his eyes and couldn't help but complain: "It's really a shameless person who is invincible in the world?" It's a shame that they can open this mouth! ”

Fang Chang wondered: "So, with such an excessive request, Cai Pengcheng can really agree?" Well, judging by the bank statement, this guy really agreed. ”

Brother Song sighed again, and then said: "Yes, Cai Pengcheng really agreed, before and after, he successively gave Lu Zhaoshan's family two million, originally planned to sell the house and car, and take a start-up capital for urban development, but now it is also ...... He could only continue to stay in Yuqiao and do the original ice cream wholesale business. ”

After being silent for a long time, Brother Song continued: "The most chilling thing about Cai Pengcheng is that they don't even care about Lu Qing's life or death, they only have money in their eyes...... Alas!

He complained to his friends more than once, wishing to kill those beasts, but his friends didn't take it to heart, only as if he was angry. ”

Qi Yuan pursed his lips and couldn't help muttering, "In this case...... I'm afraid that few people will go to their hearts, thinking that he really wants to kill. ”

Su Ping glanced at him, and he immediately shut up, not daring to continue muttering.

At this time, Lao Hai stood up and took over and said, "About Lu Qing and Lu Zhaoshan's family...... We also found a lot of clues. ”

"Say." Su Ping said softly.

"To put it simply, this patriarchal family is very serious." Lao Hai pinched his notebook and said in a deep voice: "As a younger brother, Lu Anran has been pampered in every way since he was a child, and he has developed an arrogant and domineering temperament, while Lu Qing seems to be superfluous, although he will not starve and freeze, but it is indeed not easy.

Finally, Lu Qing met Cai Pengcheng, and when they were talking about marriage, they opened their mouths again, asking for a house, a car, and a bride price - and the house and car were not for their daughter, but for Lu Anran's name, so that Lu Anran could get married and marry his wife. ”

Su Ping: ???

After a while, he asked in disbelief, "No, can you still be shameless to this extent?" This...... Too much, right? ”

"Yes, it's too much, and even if they are pointed at by countless people, they won't change their minds, not only for a house and a car, but also for a bride price of 600,000 yuan."

"Convincing." Su Ping rolled his eyes.

Qi Yuan asked curiously, "What happened later?" Cai Pengcheng satisfied them? ”

"Nope." Lao Hai pursed his lips and said: "Lu Qing couldn't bear it, broke up with his family, and even directly reported to the police, causing a lot of uproar, and finally obtained the household registration book, and Cai Pengcheng received the certificate, and then moved out of the household registration, and let go of the old and dead with Lu Zhaoshan's family.

Later, when the wedding was held, Lu Qing did not call Lu Zhaoshan's family directly, but invited relatives and friends in her own name, and specially invited a few security personnel, so that they would drive away directly as soon as they saw Lu Zhaoshan, and did not give them a chance to make trouble. ”

Speaking of this, Lao Hai couldn't help but sneer, and then continued:

"It can only be said that Lu Qing knows them well, on the day of the wedding, Lu Zhaoshan and Lu Anran really came, but they were directly stopped by the security guards, and then they sprinkled on the spot, but they were stopped by the security guards, and then Lu Qing called the police directly, saying that they were picking quarrels and provoking trouble."

"Well done!" Qi Yuan's eyes lit up.

"As soon as the brothers from the police station arrived, they immediately withered." Lao Hai said:

"Lu Qing completed the wedding first, and then came to the police station with Cai Pengcheng, claiming that they must be severely punished if they are not selfish, and at the same time, the brothers at the police station also warned Lu Zhaoshan that once they were established, they could be punished for five to ten years, which scared them and did not dare to make trouble again."

Su Ping sighed and said, "It's quite relieving, but it's a pity that I didn't put these guys in prison in the end." ”

Lao Hai shrugged: "It's been about two or three years since this big farce, maybe four or five years, I can't tell you the specifics." Lu Qing and Cai Pengcheng finally came to the door again, seemingly wanting to reconcile with Lu Zhaoshan's family, but they seemed to quarrel again, and finally broke up unhappily. ”

After a pause, Lao Hai continued: "This is the last time they came to the door, and they haven't been back and forth since then, until Lu Qing died in a car accident, and Lu Zhaoshan's family heard the news and looked for them with their faces." ”

Su Ping fell silent.

Lao Hai waited for two seconds, and saw that Su Ping didn't mean to ask, so he continued: "Actually, according to my investigation results, Cai Pengcheng has always played the role of mediator, mediating the relationship between Lu Qing and Lu Zhaoshan's family.

But that family was really too much, and it was difficult for Lu Qing to reconcile with them at all, so they finally agreed to come to the door to solve the conflict once, but in the end they quarreled again.

Since then, although Cai Pengcheng has been working hard, he has never achieved results - he has always felt that there should be a misunderstanding between Lu Qing and Lu Zhaoshan's family, and that no parents should really do this to their children, but ...... It wasn't until Lu Qing died that Cai Pengcheng finally understood that not all parents are competent. ”

Su Ping bowed his head lightly, agreeing with this sentence.

In fact, after being a criminal police officer for so many years, he has seen a lot of animal-like parents.

After a while, Su Ping continued: "Judging from the results of the visit...... The facts of the case are very clear and clear, Cai Pengcheng couldn't bear it, killed in anger, and then became disheartened and determined to commit suicide. ”

Speaking of this, he paused, his eyes narrowed slightly, and then continued: "But...... This is only the general context, and there are many details that cannot be explained.

For example, why did he go to great lengths to pull the body away and freeze it, pull it back to the scene to dismember, and glue it neatly and neatly; And why go to great lengths to seal the scene; Why did he choose to commit suicide in Liufeng Mountain, these are still doubts. ”

"And." Qi Yuan suddenly interjected and said, "Cai Pengcheng has been dead for four or five days, but the window at the scene was only pushed open early this morning - then, who is the person who pushed the window open?" What does he want to do? ”

Su Ping glanced at Qi Yuan and nodded slightly.

At this time, Yan Zhongxin said: "The time of death can basically be determined, Cai Pengcheng should have committed suicide at noon on the thirteenth, but the specific time is difficult to calculate." ”

Su Ping bowed his head lightly and said, "Enough." ”

Immediately after, Ah Xian also said: "We investigated the cold storage and rental house rented by Cai Pengcheng, and indeed found blood and a small walk-behind cutting machine, as well as a homemade high-voltage electric baton and a sharp dagger, that is, the location of the frozen body, the murder weapon and the dismemberment weapon. ”

Xiao Gao of the technical team added: "The high-voltage electric baton, we have tested, the voltage is indeed not very stable, and there is a certain risk in use, but it is extremely powerful, theoretically the contact can instantly shock the person, and if it cannot be treated in time, there is a high probability of death in a short time." ”

"Has the murder weapon also been confirmed...... Su Ping said softly: "Then there is probably no suspense in this case...... But some details, if possible, try to figure out as soon as possible.

Song, I'll leave this to you, do your best. ”
