Profiler 4: Criminal Investigation Team

"Why isn't it suitable?"

Ke Luoluo said persistently: "Then I heard that you used to be the future of the Jiangcheng branch, and murders happened wherever you go..."

"Hey, I said, this lesbian, why did you assign a leader?"

Hou Xiyong came out and said, "This is the scene of a murder case, can you be more serious!"

Jiao Yang felt that Hou Xiyong and Ke Luoluo were talking nonsense, but he had been carefully observing Xie Jiacheng's reaction.

I saw Xie Jiacheng staring at the spray bottle, with an unbelievable expression on his face, his eyes were full of pain, but there seemed to be a glimmer of hope faintly, his expression was very complicated and contradictory.

Jiao Yang felt that, judging from Xie Jiacheng's reaction, the person who caused the frost marks on Niu Lixia's forehead and back of her head was indeed not him.

Several people went through follow-up inspections and found no new clues, so they sent Xie Jiacheng back to the detention center, and then drove back to the police station.

When he came to the last traffic light in front of the city bureau, Jiao Yang saw a delivery boy in a blue jacket speeding past with a huge incubator on his electric scooter.

Jiao Yang was startled, that kind of silk cotton seems to be the inner filling of this kind of jacket or thin padded clothes...

On the day of the presumed incident on the 12th of last month, between [-] and [-] p.m., the surveillance camera captured several delivery people entering and leaving the community.Could it be...

Jiao Yang frowned and said, "Let's go back right away and watch the surveillance video of the day the crime happened again!"

Jiao Yang went back and told everyone about these findings, and the task force was very excited.

Yang Wei heard Jiao Yang's analysis of the method of throwing the corpse, and immediately opened his mouth and said: "Isn't it? You actually used the takeaway incubator with rice to store the corpse? It's nothing more than the previous one, it's disgusting at best. If this happens after throwing the corpse , and continue to take orders and deliver food, how scary! It’s okay if it’s packed in a box, but it’s still a woven bag. In case there’s a little water or something, it’s okay if the food is well sealed, otherwise..."

"vomit!"

Ke Luoluo couldn't take it anymore and said, "You can't even order takeaway. Shut up quickly, maybe it's a delivery car!"

"Aren't the express cars the same?"

Yang Wei wondered: "Could it be that when people shop online, they don't buy food? Besides, the takeaway packaging bags are still made of plastic, and many express packages are packaged, but cardboard boxes are more likely to be polluted?!"

"Ahhh!"

Now which young girl doesn't chop her hands every day?Receiving express delivery every day is one of Ke Luoluo's hobbies.She couldn't help screaming, "Yang Wei, you are so disgusting!"

Yang Weidao: "It's none of my business, it's obvious that the murderer doesn't care."

"All right."

Jiao Yang said: "Yang Wei, if you have the skills to speak, you can find out which courier it is."

"Good team Jiao!"

Yang Wei grinned and said, "Just try my new software."

Jiao Yang immediately led someone to re-watch the surveillance video of the community on the day of the incident and the days after that.

Yang Wei entered all the clothing that can be found locally and has a relatively large number of users on the food delivery order platform, and made a simple imaging capture software.

After replacing the human eye recognition with software, the work efficiency is greatly improved.

Because the community is large, there are dozens of buildings in total.It was found that on the 12th and 13th of last month, there were dozens of takeaways who came in and out, and each of them carried a delivery box behind their electric car or motorcycle, which belonged to multiple order platforms.

There are also eight, nine or even double-digit couriers to deliver goods every day.Except for the couriers of the postal service who bring the country's exclusive canvas bags to deliver the express, the rest of the couriers all enter and leave the community with electric vans.

Even during the time period when the incident was likely to occur, there were many deliveries and couriers coming in and out.And these people are likely to kill and throw their bodies away.

"It's not easy to check this thing!"

Hou Xiyong looked at Ke Luoluo and Yang Wei's partner, entered the license plate number one by one, scratched his head and said: "Boss, there are so many people, I don't know if this method is really used to dump the corpse. We don't know the murderer either. How can I find my height and weight?!"

"The old way, use the cross-exclusion method."

Jiao Yang said: "The deceased Niu Lixia was more than 1 meters tall. Although she was relatively slender, she was still an adult woman. Based on our previous experience and the calculation of the area of ​​the real body bag, at least a 60-meter body bag is needed to hold the body." First, exclude the delivery staff whose takeaway box is below this size. Then, according to my observation, the delivery time of the delivery staff is from 26:9 am to 7:12 pm. Let’s assume that Xie Jiacheng’s confession is true, then On the night of the 8th of last month, couriers who have not entered or left the community after [-] o'clock will be placed in the second batch."

While the staff of the special case group checked the situation of the takeaways and couriers in batches, the forensic department worked overtime and made a test report.

The report confirmed that the cotton wool that Jiao Yang and others found in Xie Jiacheng's home was a polyester material called 3M cotton.This is a monofilament fiber that is water resistant and is a common filling in better quality jackets.

On the other hand, the fingerprints found on the moisturizing spray bottle belonged to two people, one was the deceased, and the three more complete fingerprints identified belonged to Jia Haishan.

This proves that the person who left the scar on the forehead of the deceased woman Niu Lixia was none other than Jia Haishan.

Xie Jiacheng, who was panicked and cleaned many times at home, wiped off some traces on the surface of the closet, but accidentally missed the moisturizing spray bottle that rolled down to the bottom of the closet, and was lucky to leave these strong evidence.

In the face of a complete chain of evidence, Jia Haishan had no choice but to explain the situation that day.

He met Niu Lixia when he went to socialize with his colleagues.Not long after the two hooked up, Niu Lixia claimed to be pregnant with his child, demanded money and goods from him many times, and threatened him with a divorce on the day of the crime, otherwise she would go to his work unit to make trouble.

Jia Haishan retired within a few years. His son and daughter-in-law are well-educated and are taking the civil service exam.If Niu Lixia made a fuss, he might lose everything.Jia Haishan panicked for a moment, so he picked up the spray bottle Niu Lixia put on the tea table and slammed it on Niu Lixia's head.

But at that time, Niu Lixia was not only fine, but jumped up and cursed, pulled Jia Haishan's hand, and hit her in the stomach.

After all, Jia Haishan was getting older, he was addicted to drinking and drinking, and his hands and feet were weak. He couldn't stand Niu Lixia's bullying, so he had to run away.

Niu Lixia didn't move after that, and Jia Haishan secretly rejoiced for the first few days.After a while, he felt that something was wrong. He knew that something had happened, and he kept following the news in secret.

Seeing the news of a young woman being killed on TV, Jia Haishan explained everything to his wife in advance.Although Jia Haishan's wife was very sad and indignant, considering the years of relationship and the future of her son, she could only agree to keep her husband.After being forgiven by his wife, the family formed an offensive and defensive alliance, and when the police officers from the task force came to the door, they all gave false statements.

Jia Haishan's daughter-in-law did not know the truth.Jia Haishan's son was afraid that his wife would leave him if he knew that he might have a murderer father.

Jia Haishan's daughter-in-law has long forgotten the time of eating that day, and she only testified according to her husband's statement, which was not intentional subjectively, so she was exempted from prosecution.Except for Jia Haishan's daughter-in-law, his wife and son were all charged with perjury and cover-up.

Whether Xie Jiacheng is the real murderer depends on the follow-up investigation.Only by finding evidence that there is indeed a third person at the scene can he clear his suspicions.

After holding a new case discussion meeting and sorting out the latest developments, Jiao Yang felt that if Xie Jiacheng's confession was true, then the most likely time for Niu Lixia's murder and body dumping was between 12:8 and 00 on the night of the 9th of last month. : Between 30.

After determining the new main direction of attack, the sight fell on the five takeaway workers who entered and left the community at this time of the day.

However, due to the low light at the time of the incident, the license plate display was not very clear.

The members of the special case team had no choice but to contact the transportation department, and obtained the surveillance video on a main road outside the community, and then they got a relatively clear license plate number, and then learned the information of the car owners one by one.

At the same time, after coordinating with multiple order platforms, it was confirmed that these four car owners were indeed the ones who took the order and delivered the food.

However, something weird happened.

The license plate number of the No.5 rider is not clearly visible anyway. He deliberately used reflective strips to cover the electric vehicle license plate.

What is even more bizarre is that almost all the order platforms used in the city have been searched, but the fifth order in the community at that time can not be found.

From 8:00 to 9:30 in the evening, the traditional dinner time has passed, and it has gradually become a special event for supper.The community is relatively old, and the proportion of young people living in it is not high. Relatively, the number of evening meal orders is limited.

Originally, the facts of this case seemed to have gradually become clear, and it seemed that the solution to the case was just around the corner, but all the clues came to an abrupt end.

The police officers of the task force were thinking, did they go in the wrong direction to solve the case?There was no third person at all, it was this Xie Jiacheng who was always lying?

Jiao Yang suddenly said: "Continue to investigate. We found the cotton wool used in the jacket at the scene of the crime. It is no coincidence that such an unidentified deliveryman appeared on the day of the incident. Normal deliverymen are on the road every day Fei Chi, how could he intentionally cover up the license plate, so he is not afraid of being checked by the traffic police? This person must have a ghost in his heart to do this!"

"I think Captain Jiao is right!"

Ke Luoluo said: "Everyone, don't forget that the female deceased's occupation is a woman who has lost her foot! Her cell phone is lost, and it is very likely that she has a communication tool or a chat software that we have not mastered. After Jia Haishan and Xie Jiacheng had an awkward dispute, they felt that they were unreliable, so they contacted other people, maybe they were customers at work."

"That could be a direction of investigation."

Jiao Yang said: "Let's find this delivery man in several ways now. The first way is what Ke Luoluo said. See if it is someone who Ke Luoluo came into contact with in the working environment. Second, if this person is If the clothes you are wearing are not counterfeit, let’s contact this food delivery platform and investigate their registered food delivery personnel.

Now they are all registered with their real names, let's see if they can find anyone who has contact with the dead woman or Xie Jiacheng and Jia Haishan.Third... Check the people Xie Jiacheng contacted on the day of the incident to see if there is any possibility that other people have learned that Xie Jiacheng had a conflict with his girlfriend. "

The members of the task force act independently.Who knows, soon Yu Xiaoguang raised his hand and said, "Head, I found something here!"
