"We searched all the manufacturers that produce souvenir wooden boxes in Neihua City. There are about a hundred or so. There are even more unregistered small workshops, and there are countless sales channels on the Internet. We basically rule out looking for information about the murderer through the boxes.

possible."

"There were no fingerprints left on the box. The murderer wore gloves throughout the crime. Based on the jagged edges of the wooden box and the lack of fabric, it can be inferred that the murderer must have been wearing leather gloves."

"In addition, the origin of the leaflet in the box has also been found. It is the third anniversary leaflet of the deceased's own supermarket. The fragrance remains on the surface of the leaflet. It must have been wiped with a wet wipe, leaving no trace. Another speculation is that the murderer

There may be some kind of obsessive-compulsive disorder that doesn’t allow other people’s fingerprints to be on your tools.”

Shi Feng turned over the report in his hand and asked: "Forget it, what about monitoring?"

The detective whispered: "We investigated all the surveillance within one kilometer centered on the park, and found no suspicious characters. Almost everyone who appeared in the surveillance has a corresponding alibi."

Shi Feng sighed in disappointment. The murderer this time killed quickly and neatly, and had extremely strong anti-reconnaissance capabilities. He was probably a professional killer.

Because ordinary people simply cannot avoid all surveillance cameras perfectly and walk away after killing people in the park.

This requires not only knowing the location of each monitor, but also being familiar with the size of the monitor's viewing angle.

Another point is that according to Wang Qiang's call record, he took the initiative to go to the park to meet someone.

After much deliberation, the possibility that Gao Fuye would hire a killer to kill Wang Qiang is still the highest.

According to the investigation, only one person who can satisfy this point and still harbor hatred for Wang Qiang is Gao Fuye.

Thinking of this, Shi Feng felt a headache. With Gao Fuye's methods, he would definitely do it very secretly and would not leave any clues to the murderer.

"Today I took everyone in the field to the community near the park to investigate door to door. We didn't have enough manpower to call the police from the nearby police station. I don't believe that no one has seen the murderer."

Without clues in terms of technology, we had to resort to the clumsy method of manpower interviews. At nine o'clock at night, there were still many people wandering outside.

"Have you informed Gao Fuye to come to the team?"

Shi Feng carefully watched the report about Wang Qiang word for word.

The criminal police officer from the technical section immediately said: "Notified, he is willing to accept investigation."

Shi Feng nodded and then turned the topic to Ai Liang: "What do you think?"

During the investigation in the past two days, Shi Feng felt Ai Liang's sense of justice from the fact that he had persisted for more than ten hours just to catch Wang Zi, and began to pay attention to this fifteen-year-old boy.

Shi Feng looked at Ai Liang expectantly. After saying so much, Ai Liang should have already made his own guess. He was looking forward to what he would say next.

Why do you, the captain of the criminal police detachment, fall in love with a fifteen-year-old kid like me?

Ai Liang said helplessly: "I don't have any opinion."

Shi Feng did not show a disappointed expression and continued to read the report.

Because he didn't hear anything suspicious in these sentences.

Under Shi Feng's observation word for word, he quickly noticed the doubts in the report.

"The owner of the supermarket is Wang Qiang? His wife is a teacher. He has just been punished and was expelled and fined. It's not bad if he doesn't owe a lot of foreign debt. How can he still have spare money to buy a commercial store and open a supermarket?"

The store is in an excellent location, opposite the community, and there are office buildings and schools nearby.

As long as there are no obvious product quality problems, you can definitely make a lot of money.

The criminal policeman from the technical section hesitated for a moment and slowly explained: "This front house belongs to Gao Fuye. Wang Qiang bought it from him for 100,000 yuan."

This kind of hen that lays golden eggs can't even be bought for 100,000 yuan, let alone the entire storefront, even a warehouse inside.

Gao Fuye would only do this kind of business unless he was crazy.

After hearing this, Shi Feng threw the document on the table and cursed: "Are all disciplinary inspectors just for free? They check our detachment every day when nothing happens. Why don't they check the traffic police detachment for such an obvious move!"

It's okay if he doesn't listen, but he gets angry when he hears it. Their criminal police detachment works very hard every day and night to investigate the case. They are not even allowed to have a break room, and they have to rely on Gao Bin to compromise and renovate the juvenile interrogation room.

Seeing the captain getting angry, the criminal policeman who made the report quickly advised him: "Wang Qiang had already resigned at that time, and his punishment had ended some time before he was purchased at a low price, so there is no problem with the procedure."

The detective who came to persuade him was immediately thrown away by Shi Feng.

Ai Liang moved to the side to avoid being accidentally injured by their movements.

Shi Feng called Gao Bin on the spot and told him to drive: "Gao Bin? Don't rest yet. Come with me to the traffic police team to check the file. This case is very likely related to a car accident three years ago."

After saying that, he looked at the criminal policeman from the Technical Section: "When Gao Fuye comes, bring him here first. If we are not back before noon, let Wang Xun help with the interrogation."

Shi Feng quickly issued instructions one after another.

Whether it's Ai Liang's retelling of yesterday's conflict between the two or the supermarket flyer in Wang Qiang's box, everything points to three years ago.

Wang Qiang's death had nothing to do with Gao Fuye, even Shi Feng wouldn't believe it even if he killed him.

He could only make one trip to the traffic police station.
