Sure enough, in the surveillance video near the supermarket in the town, the suspect was found, he was wearing a black peaked cap, a black long-sleeved shirt and trousers. Although we can see in the surveillance video that the suspect is not wearing a mask, because the suspect always has his head down, and the surveillance video itself is not clear, we did not obtain his facial features.

Lao Lu said to me: "It's been a few days since the crime, and you said that this suspect is still a foreigner, maybe he has already left Wanzhou." ”

I said: "It is quite likely that the suspect will leave Wanzhou, but this will not affect our case, because since this person has been active in Wanzhou, we can use the surveillance video to find his activity track, and even find video with clear facial features." ”

Lao Lu nodded and said, "I will increase manpower to investigate the surveillance video of the whole district in the past few days." ”

I said, "There's one more detail. Maybe this guy has changed his outfit, but there must be a bag on him, but I'm not sure if it's a satchel or a backpack yet. But I'm sure this bag is not small. ”

Lao Lu instructed the staff of the technical department to retrieve the surveillance video of the whole area, and dispatched more than 50 criminal investigators to investigate the surveillance video that lasted for more than 10,000 hours. The only person they were looking for was this man, a man wearing a cap, long sleeves and trousers, and carrying a satchel or backpack.

I made a careful observation of the suspect's steps in the town's surveillance video, and informed all the detectives about his steps. Because I was worried that the suspect would change his appearance, I could only judge this person in the surveillance video by his body shape and steps.

After a week of investigation, the criminal police finally found out. In these more than 10,000 hours of video, traces of the suspect have been found in many places, and he has not changed his appearance, still wearing a black cap and long-sleeved trousers that do not match this season. It's just that he carries a large black satchel on his right shoulder, which looks a little bulging. I speculate that this bag contains his tools and the 100,000 yuan.

After careful research and judgment, the trajectory of the suspect in the surveillance was analyzed, and it was found that the suspect had never taken any vehicle. His final destination was not a bus station, but a train station.

Just outside the train station, we were able to capture a clear footage of the suspect's face. Judging from his physiognomy, this person is five big and three thick, and his vicious eyes seem to be about to eat people at any time. The so-called face is born from the heart, and I think it is vividly embodied in this criminal.

Lao Lu took a screenshot of the suspect's facial video and printed it out. He looked at the portrait and said, "This man went to the train station, is he going to escape by train?" ”

I pointed to a surveillance camera and said, "Look, this is a video taken by the surveillance inside the train station, and you can see that this person is not on the train, but walking in the direction of the tracks." And this train is a train to Chengdu, and his walking direction is also in the direction of Chengdu. ”

Lao Lu was a little surprised and said, "What? Is he going to walk to Chengdu? ”

I said, "It's obviously impossible. The reason why he chose to walk along the railway is that I think his destination is not far away, and even walking will not take much time. ”

Lao Lu said: "You mean that his destination is in the city along the railway. ”

I said, "Yes, and probably the closest city along the line." ”

Lao Lu said: "The nearest stop is Fenshui Town. No, if he is going to divide the water, he will not choose to walk along the railway, and he can take the provincial road, then he should go further afield. The next stop of the water division is Liangping District, could it be that his destination is Liangping? ”

I nodded and said, "It's very likely." Now that we have a high-definition mugshot of the suspect, I think he's nowhere to hide. It's only a matter of time before he catches him. ”

Old Lu En sighed and said, "I will immediately gather people and go to Liangping." ”

I said, "Wait a minute, I'm going to check with the family of the deceased to see if this suspect is an acquaintance of theirs." ”

I showed the photo of the suspect to Xiao Li, the son of the deceased. Xiao Li really recognized this person immediately, he said that this person was a carpentry master who used to come to decorate their home, and his hometown was Liang Ping.

Now I understand why the suspect is so familiar with the way and goes straight to the safe, it turns out that there is such a relationship. And according to Xiao Li's description, it is more certain that the murderer is from Liang Ping.

Lao Lu immediately mobilized the police, and with the cooperation of the Liangping Public Security, through the high-definition photos of the suspect, the suspect was quickly arrested in a hotel near the Liangping Railway Station.

After the suspect was captured, 100,000 yuan, a single-edged dagger, a pair of binoculars, and the black cap were found from the large black satchel beside him.

After that, the murderer was escorted back to Wanzhou for interrogation, during which he confessed to the crime of killing Lao Li and his wife and their nanny.

The suspect's name is Du Dayong, 43 years old this year, from Hucheng Town, Liangping District, divorced, and has a son. He was born tall and strong, and has been a carpenter for nearly 25 years, making him a good hand.

He originally had a happy family, but because of his wife's cheating, the family broke up, and his son had reached the age of eighteen and dropped out of school to work on the coast.

Du Dayong, who lived alone, spent his days drinking to drown his sorrows, abandoned his craft, and contracted the vice of online gambling.

He became increasingly addicted to online gambling, and finally reached the point where he could not extricate himself, lost his family property little by little, and finally ended up destitute and owed a lot of gambling debts.

Just when Du Dayong was cornered, he thought of robbery. The target of his robbery was the home of his employer, who used to work as a carpenter. Among the employers who recruited him, Lao Li's family was the richest, and he clearly remembered that Lao Li's family had a safe. So in order to pay off his gambling debts, he took a risk and came to Wanzhou and robbed and killed the old Lu family.

When I asked him why he chose to flee on foot after the robbery and murder, he told me. After the killing, he was terrified every day, and everyone he saw thought was a plainclothes policeman. He felt that the car ride was a closed place, and if the police showed up, he had no way to escape. So on foot, if you encounter a policeman, you can run away at any time.

His idea is ridiculous, the French Open is restored and not leaked, can he escape?

As it turned out, apparently not.
