In addition to the fact that the body could not be found, and the missing person who matched the characteristics, there were many doubts in this case.

For example, the suspect, Nong Zhifa, claimed in his memoirs that in September 1999, he attacked a female victim outside a movie theater in Chaohai City and knocked her unconscious.

He then dragged the victim into the wild, where he forcibly killed him and buried him on the spot.

According to the records, the woman is 1.7 meters tall, wearing a brown trench coat and red high heels, and the woman's private parts also have a plum blossom-shaped birthmark......

Subsequently, Wang Can searched all the original disappearance records, but did not find the missing person with the characteristics.

But the strange thing is that through search and comparison, it was found that the crime described by Nong Zhifa was very similar to a disappearance case in the southwest block of Haifeng City.

In this case, Nie, a 23-year-old song hall attendant, disappeared after work and his whereabouts are still unknown. And Nie's dress is almost exactly the same as Nong Zhifa's description.

Even, through the family, it was confirmed that the woman's private parts did have a plum blossom-shaped birthmark.

However, Nie disappeared in August 1999, a month earlier than the time described by Nong Zhifa.

Moreover, Haifeng City is 170 kilometers away from Chaohai City, and Wang Can has to suspect that Nong Zhifa may have misremembered the time and place.

The Nie who disappeared in Haifeng City is the victim mentioned by Nong Zhifa in "Memoirs of Murder".

As a result, the location of the buried body has become a mystery, and it is now impossible to find out.

In addition, through the questioning of the prison guards and fellow inmates of Nong Zhifa's prison, many doubts also emerged.

These people claimed that Nong Zhifa's mental state had been unstable since he was imprisoned. He is sometimes irritable, sometimes docile, sometimes muttering, and seems to have a certain mental problem.

It is said that in the later period, his personality became more and more withdrawn, so he did not have any friends in prison, and people did not know him very well.

In addition, there is another important doubt, and it is also the most direct doubt, which is also bothering Wang Can, that is, about the trajectory of Nong Zhifa.

According to the "Murder Memoirs", all the crimes committed by the suspect were between 1993 and 2000, and the murderer brutally killed 13 victims between 7 years.

However, after several days of visits and investigations, the police found that Nong Zhifa's trajectory during the crime seemed to have some discrepancies with his memoirs.

Nong Zhifa's experience was relatively bumpy, he had worked for people and engaged in small business, he had been to many places, and his basic activities were in the southeast coastal area.

At first glance, his trajectory and the murder memoir are relatively mild, but if you compare them carefully, you find that many times and places do not match at all.

Among them, the most obvious is that in 1996, when Nong Zhifa was 96 years old, he went to Halongjiang to do a breeding business for a year, and then returned to his hometown because of the loss of business.

However, he claimed in his murder memoirs that he had killed a total of 3 people in 96, but all 3 crimes were committed from the southeast coastal area.

As a result, there is a clear difference between the two.

I don't know, did he quietly return home during his time in the Northeast, or was there another reason?

However, due to the long age, this matter is no longer easy to verify, so after investigating for so long, Wang Can still got no clear results.

In addition, Nong Zhifa's personality and his life experience are also somewhat different from the murderer in the murder memoir.

Therefore, after investigating for such a long time, this case has exhausted Wang Can and is about to force out the problem.

It is conceivable that when he saw Zhao Yu rushing over from Xiangjiang to help, he was naturally overjoyed as if he had seen a savior, and he didn't dare to delay for a second, so he explained all the investigations of the case to Zhao Yu one by one.

After Zhao Yu learned about the case, he also felt a little mixed and unpleasant.

Before that, he had always felt that this case was a little abnormal, and now he was both excited and worried to see the case found out like this.

I am excited that I have another difficult case to investigate, but what worries me is that this case is not the same as any previous case, and many previous detection methods are completely useless.

Moreover, due to the age and the large number of victims, if you really investigate it carefully, it is tantamount to a huge and heavy project, and I don't know when it will be thoroughly investigated.

But no matter what, Zhao Yu quickly devoted himself to the investigation of the "Memoirs of Murder" case, and he led his team to study the case with Wang Can to find a breakthrough.

As a result, when the research reached the third day, they finally caught a bright spot.

It turned out that among the five murder cases that had been verified, one case caught Zhao Yu's attention.

According to his memoirs, Nong Zhifa claimed that he raped and killed a woman in the toilet of the Chaohai National Sanatorium on a certain day in 1995.

Later, after Wang Can's investigation, the authenticity of the case has been confirmed, and such a case did occur back then.

The victim, an employee of the nursing home, went to the outdoor toilet because she was in a hurry late at night, only to be attacked by gangsters and eventually brutally murdered.

The murderer did not dispose of the body after the killing, but discarded the deceased in the toilet on the spot, although the follow-up investigation found a number of suspects, but in the end all the suspicions were ruled out, and the case has not been solved so far.

Nong Zhifa wrote in his memoirs that he was guarding the construction site in Chaohai City at that time, and when he was bored at night, he wanted to find a woman to relieve his boredom, so he wandered around looking for a target.

At that time, the walls of the sanatorium were still rudimentary iron fences, and through the iron fences, he saw a woman using a flashlight to go to the toilet, so he climbed over the fence, followed in, and then committed this cruel crime......

Originally, according to the previous practice, he had to find a way to dispose of the body, but the woman was so heavy that he could barely drag it.

So, I had to throw it in the toilet......

The description of the victim and the crime in the memoir is consistent with the police records, so Wang Can can conclude that the case is true and the murderer should be Nong Zhifa.

Because if it was someone else's doing, Nong Zhifa would not have understood it in such detail.

Now, the reason why Zhao Yu focused on this case is because he found in the police records that back then, the police not only found the shoe prints of the suspected murderer from the toilet and the yard, but also a rare eyewitness appeared in the case!

Coincidentally, at that time, there was a patient named Liu Cheng living in the nursing home, and his room was facing the outdoor toilet.

After the incident, Liu Cheng reacted to the nurse, saying that he saw the murdered female employee walking into the toilet that night, and also saw the suspect following the female employee into the toilet, and even, he saw the suspect's appearance clearly!

However, because Liu Cheng was a mentally ill person, the hospital did not pay much attention to it at that time, and only told the criminal police who handled the case about it.

As a result, through the questioning of the criminal police, Liu Cheng was able to accurately tell the location of the suspect who climbed over the iron fence, which surprised people......
