The dinner in the evening was very simple. Wang Yu took Sun Yu to an old restaurant from eight years ago.

Private kitchen dishes are cheap but can leave people with endless aftertaste.

The two of them drank half a pound of liquor from a bottle of liquor. Wang Yu was already drunk and began to talk about the students he had taught in recent years.

Sun Yu responded to Wang Yu while deducing last night's case.

As Sun Yu expected, Lei Zhen and the school teamed up to check the students' sleeping conditions last night, and at least they were able to confirm that those in the same class as Xiao Ting were not suspected.

But with Xiao Ting's charming appearance, there are definitely many people who like her. If we expand the scope of the investigation, we will definitely find a needle in a haystack.

When Wang Yu mentioned drinking before, he suddenly gave Sun Yu a little inspiration.

The crime occurred at 1 a.m., and the murderer was someone Xiao Ting knew. He was basically a student. So why was the student there?

There are two possibilities,

The murderer was out drinking last night, which is a very common situation for college students. He came back very late and came in from the east gate. He met Xiao Ting in the back.

The murderer was drinking in the back mountain for some reason. The basis is that when Sun Yu was walking around the back mountain today, he saw a lot of randomly discarded wine bottles in the forest and met Xiao Ting late at night.

The reason why they focused on drinking was because Sun Yu subjectively believed that this was a murder of passion.

Many passionate killings are caused by impulse. Although killing sounds simple, it is not that simple to muster the courage to kill.

After all, the University of Finance and Economics is a first-class university in the province, and the personal accomplishments of its students are relatively high. Over the years, there has only been one scumbag, Luo Jia.

Drinking can make people cowardly. Last night was a Saturday, which was the peak time for college students to drink and have dinner together. Therefore, Sun Yu thought that the murderer must have drank a lot at that time and pushed Xiao Ting down on impulse.

Since there are no clues, it is better to try your luck in this direction.

Why couldn't it be that the murderer discovered that Xiao Ting was fooling around, and then waited for her in the back mountain with the intention of murdering her?

Dong Yang asked Sun Yu on WeChat. At this moment, he was not questioning, but asking for advice humbly.

Are you planning to commit murder and waiting for someone in the back?

If it was murder, the first murder must have been carefully thought out. In order to avoid being suspected, he would never choose a place that was closely related to him.

After reading Sun Yu's response, Dong Yang nodded with satisfaction.

"Ahem!" Dong Yang stood up and cleared his throat.

The special case team is now divided into very comprehensive areas. The case is discussed in the large conference room and the office is in the collective large office.

Not only are workstations designed for Xia Lan and Lei Zhen, but Sun Yu's position has also been reserved. Sun Yu is not here at the moment. As his representative, Dong Yang naturally sits in this position.

Seeing everyone looking at him, Dong Yang chuckled and repeated Sun Yu's deduction.

Xia Lan would naturally choose to listen to Sun Yu's words.

Soon, Xia Lan formulated a new investigation scope.

As a male, there were no signs of struggle at the scene. It can be seen that the murderer was very strong and very fast, which ordinary girls could not do.

He is a college student of Finance and Economics and is known to Xiao Ting. The two of them have at least communicated many times, otherwise Xiao Ting would not be able to walk with him late at night.

This person had drank alcohol that night. He might have just returned from a class reunion, or he might have bought alcohol at a nearby retail store and drank it in the back yard.

Even though the scope was given, Xia Lan didn't have high hopes.

In a passion killing, if the first round of investigation is inconclusive, it will be difficult to find the murderer in subsequent investigations.

······

A week has passed, and Xiao Ting's murderer has not been found.

"Hey!" Dong Yang lay on the sofa frustrated, staring at Sun Yu who was playing a mobile game opposite him like a resentful woman, "Brother Yu, is it so difficult to handle the case?"

Without taking his eyes off the phone screen, Sun Yu said nonchalantly: "There are similar passionate killings in China every year.

Although the murderer committed a murder for the first time, by chance, he did not leave any evidence. However, he never committed another crime again, so it is difficult for the police to find such people."

"Is it really that difficult? Is it more difficult than the serial murder cases you solved before?" Dong Yang looked puzzled.

Sun Yu nodded, "The simpler the method, the less likely it is to be discovered. If Mingyang hadn't been at the scene that day, this case would have been judged as a mistake."

"Wouldn't that make it an unsolved case?" In Dong Yang's mind, Sun Yu is an omnipotent detective. He is not unwilling to do so, but he is unwilling to accept Sun Yu's 100% case detection rate.

Sun Yu finally glanced at Dong Yang and raised his eyebrows.

"Although I don't want to admit it, if there is no major turning point later, it will basically be classified as an unsolved case."

As soon as he heard that there was still hope, Dong Yang moved to Sun Yu's side excitedly, "What major turning point?"

"For example, after the murder, the murderer has nightmares every day and is mentally tortured. He surrenders to the police in desperation, or his conscience makes him aware."

Dong Yang was originally listening very seriously, but when he saw the smile on Sun Yu's face that was almost unbearable, he immediately knew that Sun Yu was teasing him.

"It's so annoying!" Dong Yang was about to imitate Hu Xueying's coquettish behavior in the past, when he suddenly heard the sound of heels coming from outside the door, and quickly sat down and put on a serious face.

Having been in the company for a long time these days, Dong Yang already knows that the two companies next door are not open all year round. If you can hear the sound of heels here, the person who comes must be looking for them.

A plump figure walked into the company. She was a woman in her 40s, wearing heavy makeup, sunglasses, burgundy hair, and a snow-white fur.

Just by looking at him, Dong Yang knew that this kind of woman was here to arrest the mistress.

"Hello!" A smile appeared on Dong Yang's face, which was exactly the same as Sun Yu's usual smile. It looked extremely bright.

The woman wanted to sit on the sofa opposite the two of them, but she curled her lips when she saw the wrinkles on the sofa.

"My friend said you are very good at finding people here?"

Sun Yu was indifferent. With Dong Yang around, he had evolved into a hands-off shopkeeper.

Dong Yang still had a smile on his face: "As long as we are in Mengshan City, there is no mistress that we can't find."

Seeing that Dong Yang could tell that she wanted to entrust him to find a mistress, the woman's expression softened a lot and she sat opposite Dong Yang.

"My husband's name is Sun Jingrun, and he is the boss of Yuechao Trading Company in the High-tech Zone. I suspect that he has a mistress outside. Can this be checked?"

"The deposit is 10,000 yuan, and the final payment after finding it is 90,000 yuan." Dong Yang directly offered the price and expressed that he could accept the commission.

The woman nodded. She had inquired before coming here about the price of a mistress here.

After signing the contract, Dong Yang happily accepted the balance. Although this amount of money was a drop in the bucket for him, the money he earned was completely different from what his family gave him.

Of course, this is for rich people.

"Sister, are you preparing for a divorce?" Dong Yang suddenly asked after collecting the contract.

The woman took off her sunglasses and looked at Dong Yang curiously, "How do you know?"

Dong Yang chuckled and pointed at the ring on the woman's little finger, "With a family like yours, you don't usually wear rings around. I feel like you can't stand that Sun Jingrun anymore."

"Hmph!" When she heard Sun Jingrun's name, the woman's face turned cold, "That bitch, if you can't do it yourself, you blame me for not being charming enough. If you go out and look for yourself, I'm done with him."

As she spoke, the woman gave Dong Yang a wink, then twisted her waist and walked out the door.

Dong Yang's face turned red. He had been in the company for so long, and this was the first time someone had teased him. Although the woman was a little older, she was very good-looking.
