The carriage was driving on the snow-filled road, and the occasional bumps and shaking proved that the road was not rugged.

Cao Chong first asked the car to drive to Xin's mansion and put Xin Hua down.

Of course, Xin Hua naturally refused, but Cao Chong was not Cao Chong a few years ago.

Cao Chong glared at him now, and Xin Hua became a young wife. He didn't dare to say a word, and got off the carriage obediently and returned to Xin's mansion.

Of course, she didn't feel much willing.

After sending Xin Hua back, Cao Chong was the only one left in the carriage. Cao Chong did not rush back to the house, but instead ordered the coachman to wander around Yecheng for a while.

Cao Chong was thinking about problems in the carriage.

Of course, the worst thing is Cao Chong's guards, who basically follow the carriage and circle around Yecheng.

Fortunately, they are elite troops, otherwise they would have been exhausted after running wildly in the snow for more than an hour.

In the carriage...

Cao Chong lay casually, with dim lights swaying in the car, illuminating Cao Chong's face a little light and dark.

Cao Chong's eyes were shining with strange light, and his mind began to collide.

To determine who the murderer is, the first thing to do is to find out his motive.

Jia Xu, Cao Pi, Sima family, Xinpi, and Emperor Xian of Han.

These may be the murderers, but if you analyze them from the motivation, you can rule out a few people.

Jia Xu has a grudge with Ma Teng and has a grudge against him. Today's situation is likely to be his work, so Jia Xu's suspicion cannot be ruled out.

This is true for Jia Xu and Cao Pi. Just when Cao Pi's expression was revealed in Dacheng Hall, Cao Chong felt that this matter had nothing to do with Cao Pi.

Even if it was not done by Cao Pi, there was a shadow of Cao Pi, so Cao Pi's suspicion could not be ruled out.

The Sima family has been keeping a low profile for a long time, and there is very little possibility of this matter. Of course, he cannot rule out his suspicion.

As for Xinpi, as his father-in-law, although he had some grudges with Liu Zhang, it was impossible to kill anyone directly.

As a veteran minister, Xinpi was very cautious and it was not an exaggeration to say that he was an old fox, and it was impossible to be so impulsive.

What's more, Cao Chong still has some understanding of Xin Pi. Now the power of the Xin family is basically in the hands of Cao Chong, and the same is true for the Xin family's dead soldiers.

Therefore, Xinpi's suspicion can be ruled out first.

In the end, Emperor Xian of Han, Liu Xie, had definitely had a reason to do this, but Cao Chong's information also knew that Emperor Xian of Han had given up everything at this time.

He seemed to just want to be a puppet emperor.

But, could it be like Goujian lying on firewood and tasting gall?

Cao Chong shook his head, he couldn't answer this question, so the suspicion of Emperor Xian of Han could not be ruled out.

In addition to motives, at this time, there is also evidence to be found, including personal evidence, physical evidence, documentary evidence, inspection and other evidence. Only when the evidence is conclusive and the criminal confesses his guilt and commits his crime, can the case be finally closed.

Of course, this is not an exclusion method, but a confirmation method.

If the evidence is incomplete or there is no evidence to point directly to the suspect, there are three ways to determine the case.

The first type: based on the forensic on-site survey results.

Forensics originated in the Qin Dynasty. During the Qin Dynasty, the official name was Lingshi. Qin law stipulated that necessary autopsy should be performed in cases of unknown causes of death. If the judicial officer fails to conduct examinations according to legal procedures, he will be punished.

Therefore, descendants also inherited the laws of the Qin Dynasty, and local departments will be equipped with corresponding forensics. The on-site identification results of forensics are the most direct basis and reference for judges to make a case.

At this time, the profession of Lingshi still existed in the prison of Tingwei.

The Song Dynasty's "Compilation of the Rebellion" records such a case. A and B traveled together. When they were about to wade across the river, A saw that B was carrying a lot of money, so he became determined to seek money and kill him. In the middle of the river, A pushed B into the river, causing B to suffocate and die.

Then he took out his body and reported to the official that B died of drowning because there were not too many scars on the body, and the judge also believed that he died of drowning.

However, the coroner tested mud and sand from the deceased's nails and nostrils, and the deceased's chest was red, his lips had dark spots, and his stomach was swelling. These test results showed that B was killed by someone who was pressed into the water and killed him.

Finally, under the evidence of the coroner's examination, A truthfully explained his motives and process of killing people and seeking money.

The second type: make careful inference based on case details and logic.

In some cases of murder, theft and unknown cause of death, if the murderer does not leave evidence of the crime, the forensic doctor cannot test the most powerful physical evidence, and the government lacks corresponding witnesses, how should the case be solved?

At this time, we need to rely on the judge's experience accumulation and meticulous thinking inference.

For example, in "The Nine-Classic Official" starring Stephen Chow, Chang Wei, a eunuch's son, brutally killed the Qi Qin family in order to occupy Qi Qin's family. In order to cover up his crime, he poured poison into the mouth of the dead to create an illusion that the deceased committed suicide by taking poison. In the end, the county magistrate Bao Longxing stabbed the throat with a silver needle and found that the deceased's throat was poisonous. When the silver needle pricked the stomach, it showed that there was no poison, which proved that the victim was poured with poison after death.

Cao Chong used this method to solve the case this time.

However, this case is so powerful that it is as simple as occupying Qi Qin's family. The interests involved in this case have affected the entire court, not just because of a eunuch.

There is also a story in history: On a dark night, an old woman was rushing on her back with a bag. At this time, a robber took away the old woman's bag from behind and ran away.

The old woman shouted that the robbery was robbed, and a kind-hearted person went to chase him. However, when he caught the robber, the robber turned around and said that the kind-hearted passerby was the robber. Because it was dark, the old woman could not tell who the robber was, and there was a lack of witnesses at the scene.

After thinking for a while, the county magistrate ordered the two to sprint along the road in front of the yamen. One of them ran obviously slowly, and the county magistrate determined that this person was a robber.

Everyone was puzzled, and the county magistrate said: "If the person who ran fast was a robber, it would definitely be impossible to be caught up."

The facts are indeed exactly the same as the county magistrate inferred.

The third type: psychological tactics allow criminals to take action without complaining.

In the case of insufficient evidence, many capable people who are good at determining cases are good at capturing the guilty mentality of the criminals and using various psychological warfare to force criminals not to speak out.

For example, in a historical drama New Three Kingdoms, after Cao Chong, who was smart and wise and deeply loved by Cao Cao, was poisoned to death (yes, the protagonist), in order to find the murderer between Cao Pi and Cao Zhi, Cao Cao asked them to go to the mourning hall to watch.

At the third update in the middle of the night, sharp and wailing cats came one after another. Cao Pi was so scared that he was trembling and did not close his eyes all night, while Cao Zhi was sleeping soundly. Cao Cao saw this scene through the curtain.

There was also an allusion during the Song Dynasty: It was stated that when he was the county magistrate in Pucheng County, Fujian, a major theft occurred in the county, with many suspects, but the evidence cannot be directly specified which one was the real offender.

Chen Shugu had a plan. He told these suspects that there was an ancient bell in the county that could distinguish between guilt and innocence. As long as you put your hand on the bell, you could get the result immediately. Then he asked the suspects to touch the bell one by one at night.

In advance, Gu asked someone to put black ink on the picture on the clock. After the suspect touched it on the dark night, Chen Shu Gu observed their hands. As a result, one of them had clean hands and was determined to be the thief.

Why choose a dark night? Because the criminals really can't see the hand that others touched the clock is black. Chen Shugu took advantage of the guilty mentality of the prisoner and accurately found the real murderer.

When Cao Chong interrogated Jia Jia, he also used psychological tactics, but that was indirect and used some small questions to draw out whether Jia Jia was telling the truth or telling lies.

Wait a moment!

Cao Chong suddenly woke up.

perhaps...

I can also use the method of stating ancient times to see who lies and who has not lies.

As long as you find out who tells the truth and who tells the lies, things will definitely become simple.

right!

That's it.
