Evidence, you need evidence to solve a case!

To solve a case, it is generally necessary to go through two parts, detection and procedure, both of which are indispensable. It will be very difficult to detect, and multiple departments and police departments will cooperate with each other to find out the suspect through various means. If it is a major case supervised by the top, it is often dozens of hours of torment and struggle, and it is a luxury to be able to squint for three or four hours a day.

Song Guyan's previous cases were also in this state, which hurt his body very much. After the case was closed, he rested for two days, but he couldn't recover.

Procedure, on the other hand, is an inevitable requirement of the rule of law. Every signature and confession must stand up to scrutiny. But there will always be problems, and once they are found to have a flaw, they will be reported and criticized. The level of policing is already harsh.

Of course, these are all inevitable in the process of the rule of law, and all you can do is to shorten this period of time as soon as possible so that the whole system can be stabilized.

Without an adequate chain of evidence, the procuratorate and the court will not be able to get through, which requires that the materials in each case must be very sufficient.

"What, except for Ma Tianming, no one else has entered the villa?" Song Guyan was a little surprised.

Xi Yao nodded affirmatively: "The angle of the monitoring probe has always been towards the gate of the villa, and if someone enters, it will definitely be recorded." ”

"What about the surrounding intersections?"

"I haven't had time to look at it yet, there are so many probes, it's a waste of time to look at them one by one. Xi Yao pouted and said.

She stared at the tech department and watched a video as well. The content in the monitoring probe is extremely boring, and it is not a soap opera, and you have to concentrate, and your mind is particularly easy to get tired.

Song Guyan scolded with a smile: "If you don't want to watch the video, I'll ask the team leader to send you to the forensic laboratory to help." ”

Forensic labs?

Xi Yao couldn't help but shudder when she thought of that smell, if she asked about that smell, Xi Yao would be able to suffer for several days.

"I ...... I haven't finished watching the video yet, what did you just say? It doesn't matter what you say, I'll talk about it when I'm done. ”

Song Guyan couldn't help but smile as she watched Xi Yao run away like a ghost.

The smile was fleeting, and Song Guyan's eyes focused on a few photos taken at the scene, and an appraisal report.

A tragic picture on a photo, even if it is only an image, can make people's hearts hairy. The identification report is the long hair and hairpins found by Song Guyan in the villa, and the laboratory has given a conclusion:

"Long hair is a natural shedding, the damage is severe, the hair roots are dry, the hair bulb is atrophied, and there is no hair follicle tissue attached. ”

As people age, the amount of pigment in their hair changes accordingly. The amount of pigment in hair is roughly the same for people of the same age. Based on the growth, shape, and color of the hair, it was initially judged that it should be a young woman in her twenties.

Because the long hair took a long time to fall out, the laboratory was only able to confirm the woman's blood type, but there was no way to collect the DNA of the target person.

Song Guyan had already predicted in her heart that the continuous bad news did not affect her mood. After being transferred from the police dog base to the criminal police corps, no case can be easily handled. If the case becomes simpler, Song Guyan will wonder if the author is going to change the heroine.

No one entered the scene, ostensibly it was a suicide by hanging, and Song Guyan felt that this was just what the murderer wanted them to see. To tell the truth, even if Ma Tianming is bankrupt, he still has a lot of money, supports female students, and lives a beautiful life, so why did he choose to commit suicide?

After Song Guyan's application, the corps agreed here that Ma Tianming's case would be temporarily investigated as homicide, so there would be much more resources that could be mobilized.

obtained Ma Tianming's consumption records through the bank and interviewed social relations, and soon confirmed several women who had unclear relationships with him.

Of course, these women will be with Ma Tianming for money, and they have no relationship at all. When the police asked for assistance in the investigation, they were extremely uncooperative. After all, it is not a glorious thing to be fostered, they are greedy for some money, and they will have to find honest people in the future.

If this is taken away by the police for investigation, the reputation will be stinky, and what man will take over stupidly in the future.

"The world is going down! We all have hands and feet, so why can't we work hard. I have to sell myself, and I don't know if it's disgusting if I use it. Xi Yao looked at the information of several women and said angrily.

"Look at this, college students from top schools in China, being a tutor is enough for her to live!

Song Guyan shook his head gently, as a policeman, what he needs is a fair position. When handling a case, it is easy to substitute one's own subjective emotions, which is very easy to interfere with the investigation of the case.

The fact that these women chose a shortcut to satisfy their vanity through the exchange of flesh and money was only a tragic omen.

She was too young to know all the gifts that fate had given her, and she had already secretly marked the price. ”

Everything in the world is nothing more than an equivalent exchange, and if you get something extra, you naturally have to pay a higher price.

If virtue is not matched, there will be disaster. If you get a position that is not in accordance with your moral character, there will be calamity.

Only self-improvement, self-struggle, and what you earn with your own hands are what you are entitled to.

"Okay, let's say a few words! Let you check the suspicion, not let you judge others!" Song Guyan advised.

If the parties hear Xi Yao's words, maybe it will be a bunch of trouble.

Xi Yao pouted, obviously there were still a bunch of words in her stomach that had not been spoken.

Song Guyan didn't know what he was thinking, so he took the information of the female college student.

Chen Yanruo, 23 years old, is still a few months away from graduation. On her resume, she excels in her studies, has served as a student cadre before, and with her beautiful face and figure, she is definitely a popular figure in the school.

Song Guyan took a look at Chen Yanruo's past, her parents died when she was young, and her grandparents raised her. It was probably this experience that made her rely on money to a certain extent, and she needed to gain a sense of security, so she chose to stoop to Ma Tianming, who was middle-aged and shabby-looking.

These are naturally made up by Song Guyan's brain, and what Chen Ruoyan's journey is like, probably only she knows.

After the company went bankrupt and basically retired, Ma Tianming's past acquaintances did not have much contact, and the police had limited access to things, and the investigation of Ma Tianming's abnormal relationship between men and women was also to find out who he had contacted before his death and who he had grudges with.

There are many things that a man will not tell his wife, but he will definitely tell his lover. Mainly because they will show off in front of their lovers, and they know that their lovers rarely come into contact with their social relationships, pretending to be forced and complaining a few words, they can also show their long-gone majesty.

Most men look for a lover in exchange for money for a hypocritical dignity. Even if the lover is screaming loudly, how many of them are real, and there is no B number in the heart.

These women still have a sense of shame, and the police notify them to go to the police station to assist in the investigation, and they all delay if they can, and disappear when they can. But if the police want to find someone, it is still very simple, even if they are reluctant, it is their duty to assist in the investigation, and they cannot be refused.

The science lab at Hucheng University has also got results, and with the help of their latest technology, the wounds of the decomposing corpses have been restored as much as possible. Underneath the obvious rope marks, there is a more smooth strangulation mark. The forensic doctor's judgment was that he should have been strangled to death with a silk rope such as a tie, and then he was disguised as a hanged suicide.

This confirms that this is a homicide, not a suicide.

"Those women didn't admit that they had an improper relationship with Ma Tianming, even if we showed them the transfer records, they still refused to speak!" Xi Yao said helplessly.

"Won't say anything?"

"That's right, and say that I'm slandering them!" Xi Yao was obviously a little angry, and her attitude was very bad, "Is the evidence conclusive, good! I don't know what they think!"

To be a lover, you don't just have to be beautiful. Especially if you want to take money from Ma Tianming, you have to have a clever mouth. With Xi Yao's big temperament, it is normal to be angry with those women and cause internal injuries.

"Don't be so impatient, when you enter the police station, they should be in a hurry. Song Guyan said speechlessly.

It seems that Xi Yao's IQ has started to go offline again, knowing that those people are trying to provoke her, they actually obediently entered the trap.

"Alright, I'll do it. Song Guyan sighed.

It turns out that Song Guyan's role is not much better than Xi Yao's, anyway, Zhou You saw that the face of the shovel official was very bad. Being able to accept the package is very low, and if you are cynical, you will be angry.

Fortunately, it was Song Guyan who restrained it, so he didn't show it.

For Ma Tianming, women are just playthings bought by money, and when they are tired of playing, they naturally have to be changed. There are many people who lack money in this world, but the most important thing is a wonderful body. As long as Ma Tianming has money, he can exchange for most of his body.

Song Guyan arranged the time of several women and Ma Tianming together, and there were three that were closer to the time of his death, including Chen Yanruo, who was deeply impressed by Song Guyan.

"Isn't your mental state particularly good?" Song Guyan took a cup of tea and handed it to Chen Yanruo.

Judging from her appearance, Chen Yanruo is very delicate, and she can also crown the harem without powder. The temperament is quiet and elegant, and it is also polite even if the teacup is connected, which is completely different from the shrews that Song Guyan interrogated before.

"Recently, I was working on my graduation project, and I haven't slept well for several days. Chen Ruoyan said softly.

Song Guyan noticed that she had heavy bags under her eyes, and she had indeed stayed up all night.

"Tell me about your relationship with Ma Tianming?"

Chen Yanruo sighed softly: "The female police officer has already asked just now, do you need to say it again?"

The police's endless questioning gave Chen Yanruo a headache. Being interrogated is naturally a very unpleasant thing.

"Yes. ”

"I admit that Ma Tianming chased me and gave me a lot of things, but I wasn't taken care of by him!" Chen Ruoyan's tone was a little excited, "You police can't guess people so indiscriminately!"

"Then how do you explain that you received a transfer of 100,000 yuan in your account? Don't tell me, Ma Tianming gave you this money because he treated you as a friend!"

"I borrowed the money from him. ”

Chen Yanruo's family background is not particularly good, but she doesn't worry about food and clothing, and her grandparents are not sick, so what is this money used for.

"I'm about to graduate and want to borrow money to start a business. Chen Yanruo explained.

"IOUs?"

"He didn't let me write. ”

Song Guyan snorted: "You don't know what Ma Tianming wants to do?"

"Yes. Chen Yanruo's tone was much weaker, "But I will pay back the money, but it's just a turnaround." ”

Song Guyan really didn't know how a high-achieving student like Chen Yanruo could be so naïve, knowing that Ma Tianming had ill intentions, and dared to seek skin with the tiger. How can I walk by the river without getting my shoes wet, Chen Yanruo is equivalent to personally sending herself to Ma Tianming's mouth.

However, Song Guyan did not choose to fully believe Chen Yanruo's words, and from her intuition, she felt that Chen Yanruo still had something to hide.

There's one thing in this that doesn't make sense.

Ma Tianming set his eyes on Chen Yanruo first, and it was obvious from the statement that when he first came into contact, Chen Yanruo was reluctant. But later asked why he was willing to open his mouth to borrow the 100,000, and the reason for this, if Chen Yan was unwilling to speak, Song Guyan would not be clear for the time being.

After some interrogation, several of the women were let back. After all, there is no evidence to prove that there are suspects among them, and there is no reason for the police to detain them.

In addition to these women who are related to Ma Tianming, the police also screened him for his past. The primitive accumulation of capital is always sinful, especially in traditional industries, and Ma Tianming is naturally no exception.

In the early days of Ma Tianming's company, most of them were also on the edge of the law, but it was only later that the company gradually entered the formalization and Ma Tianming relented. According to his case record, there are not a few people who have offended.

In the absence of a clue, vendetta is also one of the criminal motives that Song Guyan needs to consider.

The interrogation continued, and the transcripts were increasing, which also complicated the case. The harvest so far is just to confirm that Ma Tianming died of homicide, but how did the murderer sneak into the villa, and he was able to commit the crime while Ma Tianming was unprepared, and Song Guyan couldn't figure it out.

To solve a case, you need to be nervous, but you can't be impatient. Peeling back the layers and selecting useful parts from a large amount of information is the most test of a police officer's professional ability.

And for Zhou You, when the shovel officer falls into this state, it is also the most boring time for him.

I didn't know if it was a few yawns, Zhou You squinted and lay on the table, enjoying the warm sunshine.

It's still interesting to go out on a mission, and accompany the shovel officer to solve the case, he can't play a role at all.
