For Wang Huadong and Sun Jie, this scene was like an open-book question, which was too simple and all the answers could be extracted on the spot.

"The murderer is a male, a single person, who should have known the deceased and had communicated with him before the fight. He is approximately 30 to 45 years old, about 1.75 meters tall, weighs about 140 kilograms, and is right-handed. Apart from that, he has a relatively calm personality," said Wang Huadong.

"The deceased died about 40 minutes ago. He struggled obviously when he died, but there was only one knife wound and not many other scratches. Judging from the condition of the body, the two people must have known each other, and the deceased was completely defenseless," said Sun Jie. "From the current situation, the deceased was not drunk or mentally ill."

"From this place," Wang Huadong looked at the two footprints outside, "the murderer was not too panicked when he left, and there was no sign of running. There was no significant difference in his stride from before he came to the bathroom, which means that the murderer might be a professional killer, or he is just too careless. From the pattern of the murderer's shoe prints, we can see that it was a pair of relatively sophisticated leather shoes. The key problem is not here, but that after the murderer left the bathroom, the footprints were very deep, and he stood here for a short while. There were also marks on the wall, which means that the murderer must have held the wall and wiped his shoes here. He didn't even take the knife with him, but he took something to wipe his shoes with. This should be a handkerchief, and generally only gentlemen would do this."

"We found a very small amount of black powdery substance from the victim's wound. We need to test it." Sun Jie said, "I need some equipment to assist me..."

"Black powder? It may be the key to this case, but it is not ruled out that the knife has been stored for too long and there is too much dust?" Wang Huadong said.

"The color is wrong," Sun Jie said, "but it doesn't matter. Just go for a test. This case isn't difficult."

"really."

The local criminal police looked a little confused. What was going on?

Is it that simple? How come we can't see it? Did you copy the answers in advance?

A scene covered in blood is very stressful for most police officers who have little experience with such scenes. The scene was covered in blood. It was difficult to obtain clues without destroying the scene. How could these two be so relaxed...

…

With the leadership's attention and the efficiency of the testing, Sun Jie soon got the results he wanted.

The main component of that very small amount of black ash is potassium carbonate.

Anyone who has studied junior high school chemistry knows that this thing is wood ash.

This should be the key to solving the case.

The cause of death in this case was very obvious and the crime scene was very simple, so Wang Huadong and Sun Jie finished their work in less than half an hour.

In such a situation, with the cooperation of technical investigation and image investigation departments, it would only take a few hours to solve the case.

However, the two had just gotten some clues from here, and when they came out, they learned that the case had been solved...

Wang Liang successfully robbed the house, and the murderer already knew who he was...

"So this case is not interesting..." Wang Huadong was not surprised at all when he heard about this: "The suspect didn't hide from us at all."

"Indeed," Sun Jie also felt the same way.

It's like two math PhDs taking part in a junior high school math competition, handing in their papers early, and then someone later says their scores don't count - they wouldn't care.

"Who is the murderer?" Wang Huadong asked.

"Professor Ye." said the local criminal police.

"What?" This shocked Wang Huadong and Sun Jie. Professor Ye? ? ?

Professor Ye is the one who met the little girl last night!

Met a ghost yesterday and killed someone today?

"So, has the person been caught?" Sun Jie recovered first.

"He committed suicide."

…

It was originally a simple murder scene, but when this incident occurred, it immediately added to the trouble.

In the junior high school mathematics competition, the last question actually requires solving the Riemann hypothesis or the Navier-Stoke equation!

Ignoring this situation for now, Wang Huadong and Sun Jie went straight to Professor Ye’s house.

…

There were a lot of people gathered at Professor Ye's house, not only Bai Song, Ren Hao and others, but also many media reporters.

The main reason was that before Professor Ye committed suicide, he wrote a blog, which caused a huge uproar!

In the blog, he clearly described the ghost he encountered yesterday, and then a little girl came to him in a dream, saying that the little girl told him in the dream that the tour guide was the murderer who killed her. Not only that, it also outlines a complete story, which makes people feel it is real after listening to it.

Professor Ye was disturbed by the girl's "ghost" and went to commit murder today. After killing someone, he chose to commit suicide to end his sin.

Professor Ye himself believes that killing is wrong and a serious sin, but he says he does not regret it.

Overall, it’s such a simple process.

But once this blog was published, it soon became a hot topic on the Internet, mainly because Professor Ye really committed suicide!

For a time, the news that the professor was possessed by a ghost immediately ignited the entire Internet.

In this situation, a lot of new posts have been posted!

Yesterday, not only Professor Ye and the two people who called the police claimed to have seen the little girl, but there were several others, but these people did not call the police!

Not everyone will blog or anything, but some people really saw it and encountered it!

The most bizarre thing is that someone actually took a photo of the little girl!

The Internet is well developed. As the photos were uploaded, countless people dug out the information of the little girl who died accidentally some time ago, and discovered that it was indeed the same person in the photo, even the clothes were the same.

The thing that Bai Song and Ren Hao were most worried about happened. The "divine light" from yesterday evening was finally brought up and someone started promoting all kinds of wrong things.

No one expected that it would quickly attract hundreds of millions of traffic in this way, and countless media and self-media began to flock to it.

"Captain Bai, do you have any experience in dealing with this kind of thing?" Ren Hao was under too much pressure.

"Don't rush to make a full statement, but you can say something to stabilize the morale of the troops," Bai Song said, "Take multiple approaches. Arrest a group of rumor mongers, ban a group of instigators, and establish official channels as soon as possible. In addition, we must carefully investigate the photo to find out what happened and how such a photo was taken. Also, those professors need to study this photo together."

"Inspector Bai does have experience..." Ren Hao said, "But I'm still worried that his credibility is not strong enough, ah..."

"I think I also have a blog account, with hundreds of thousands of followers, and it seems to have a pretty good reputation," Bai Song said, "You guys draft the official announcement, and I'll do my part."
