Profiler 2: Criminal Investigation Brigade

Unexpectedly, after the crime on December 12th, the murderer disappeared as if the world had evaporated.

The members of the task force had mixed feelings. They hoped that the murderer would never appear again so that no new innocent people would be victimized, and they also hoped that the murderer would appear as soon as possible so that he could be brought to justice as soon as possible.

2019 ended in various conferences. On the night of the 31st, Lu Yuanli and Jiao Yang went back to Jiao's house for dinner.

Although Zhou Peiyan still regarded Lu Yuanli as air, it seemed to be a kind of acquiescence.Moreover, Zhou Peiyan never suffered from coronary heart disease again, which made Jiao Yang somewhat relieved.

The time has entered mid-January 2020, and a difficult disease that has never been seen before appeared on the land of China.A large number of grassroots policemen have been transferred to participate in epidemic prevention work, which seems to make it more difficult to solve the case.

Just then, the murderer appeared again.

On the morning of January 1, the police force received a report from the landlord of a residential building near University Town, saying that a female resident named Xiao had been killed at home.

Today, it was already the New Year's Eve in many cities, and such vicious cases still happened, which naturally made people even more indignant.

Jiao Yang learned through the files that the deceased, Xiao, was 42 years old and a foreigner.Xiao divorced her husband in the early years, and this time she came to Shanghai to study with her 18-year-old daughter, and she lived here for only a few months.

Neighbors said they heard the sound of the door opening, and Xiao arrived home around 10 p.m.The scene was very similar to the previous case. Xiao was naked and died in a pool of blood, and her underwear was thrown on the floor.The murderer's crime is still clean, leaving few traces.

Strangely, a bag of peanuts in the deceased's home was also spilled all over the floor.At first, the task force suspected that the deceased bought peanuts to go home and happened to encounter the murderer.

However, after Jiao Yang checked, he found that the date on the outer package of peanuts was three days before the crime, not the day the deceased was killed.

It seems that the murderer sprinkled it. What kind of metaphor is this?

Lu Yuanli coughed and said, "When I went to the flower and bird market, I saw a book on a street stall. It said that during the Ming and Qing Dynasties in your place, it was popular to build chastity archways for widowed women. There was a chaste martyr on it The dictation said that at night, throw a box of Go pieces on the ground, pick them up one by one, and put them into the box, so that people will be tired and go to sleep. The next night, throw them again and pick them up again.

I didn't think about it at first, but then I saw that the peanuts here seemed to be relatively small like Go pieces. If they were scattered, it would take a long time to pick them up.So I think, the murderer may mean this. "

What does this mean?The murderer mocked the victim's loneliness in the boudoir, no man?Do you have to pick up Go and peanuts to fall asleep at night? !

I'm stupid, Jiao Yang rubbed his temples, if this person really meant it, it would be disgusting.

Unexpectedly, the police force had unexpected gains in subsequent investigations.

Xiao's daughter responded that she couldn't find her mother's mobile phone, and it seemed that she lost it at the scene.

The police immediately inquired about Xiao's mobile phone card information through the telecom operator, and the result was extremely surprising. From January 1th to 18th, there were actually five calls on the deceased's mobile phone call list.According to the autopsy results, Xiao was killed on the evening of January 19.In other words, Xiao's mobile phone and SIM card may be in the hands of the murderer, and he even made a call.

The police force immediately used technical means to investigate the location where the mobile phone card had stayed.

Through the cooperation of telecom operators, the police found out that the mobile phone first appeared in Minxing District, then appeared at Shencheng South Station, and then moved in a large area in the direction from Shanghai to Jiangning.

The police force felt something unusual about this, and immediately investigated the people who had called.One of the callers was a classmate of the deceased's daughter, a young girl with a pretty profile picture.

She said that the person called her twice at 19 o'clock in the morning on the [-]th, during which the other party remained silent.But she felt that the person holding Xiao's mobile phone on the opposite side seemed to be in a noisy environment, and there seemed to be a "clicking" sound.

Jiao Yang felt that this "click click" sound was like the sound of train wheels.The murderer may have gone to Jiangning, and it seems that he took a train.

However, Jiao Yang is still the same old saying, everything will be known only after verification.Jiao Yang personally led people, drove from Shencheng South Station, took the Changhe Expressway all the way to Jiangning, and simulated the trajectory of the mobile phone passing through the intermediate cities at each time point.

Practice results have proved that there is basically no overlap with the results obtained from the operator in terms of time points. The holder of the mobile phone card can basically confirm that he did not start from the highway. He should be taking the k528 and four-train train I went to Jiangning.

However, the sound of the train running did not match what the girl heard.Another one, considering that the murderer is more familiar with the fringes of the city and the victim's description of his clothing, the murderer's financial situation seems to be not very good, and the possibility of taking the high-speed rail is very small.

After many repeated trials, the police force finally investigated the target and locked on train k528.

If it was before, it would be even more difficult to find out the passenger information on the entire train.However, at this time, the passenger health status registration card during the "epidemic" period gave the police force extraordinary convenience.

January 1st is already the 21th of the twelfth lunar month, and the Spring Festival is approaching.However, everyone in the police force has no intention of celebrating the festival.They took back all the registration cards of the health status of the passengers on train K27 on the morning of the 19th, divided them into several copies, distributed them to the members of the task force for screening, and then exchanged and checked with each other to see if there were any suspicious persons missing.

According to the passenger registration card records, there were more than 19 people who got on the train from Shencheng South Station and got off at Jiangning Station on the 350th, including more than 200 men and more than 140 women.

The police force checked the passengers in more than a dozen carriages one by one, while Jiao Yang and Zhang Xianning led Hou Xiyong, Shen Rui and others to investigate more than [-] crew members and service personnel.

This work is very complicated and trivial. First of all, it depends on whether the person card matches, and also based on conditions such as age, weight, height, and place of origin.

The task force was set up in the headquarters of the Public Security Bureau of Jiangcheng District, and the information of more than 300 passengers was plastered on the four walls. Those who didn’t know it thought that the Serious Crime Brigade was diverted to find people...

The investigation work implements a contract-to-person responsibility system, who reviewed it, why it was excluded, and evidence provided.The police officers also traveled back and forth to Wuxi, Hangzhou, Jiangning and other places many times.

From the 21st to the 24th, with the assistance of computers, dozens of members of the task force spent three full days. The first round of investigation was basically completed, and a total of 17 male suspects were identified.

There is a large mobile phone trading market near Jiangning South Railway Station. The business has been booming, and there are many second-hand mobile phones.

When Jiao Yang was experimenting with the driving route from Shencheng South Station to Jiangning, he considered that Xiao’s mobile phone card had never been used after arriving in Jiangning, so he once called people to this mobile phone market to carry out a test. Surrounding survey.

In this return visit, Hou Xiyong and others got an unexpected harvest.In a mobile phone store, they found the victim Xiao's mobile phone.

After questioning Han, the owner of the mobile phone shop, they learned that the appearance and characteristics of the person who came here to sell mobile phones were similar to the descriptions of the two surviving victims.

Han also told the police that this person visited his store twice.Because he doesn't have an invoice, the industry rules are to suppress the price of such unknown things.The first time this person thought the price was too low and didn't sell it, but later he came back and tried for a long time, and forced Han to pay 20 yuan more before selling it, which made Han no longer want it.

This clue made the police officers very excited. On the morning of January 1, the results of the investigation of passengers on train k24 came out.Even though it was New Year's Eve, no one in the special case team had time to call home, let alone go back.After Jiao Yang's report, Li Jinsheng immediately decided to organize the identification the next day.

The police force is still very confident in this identification.In addition to arranging the identification of the two surviving victims, the police also specially invited Han from Jiangning.

After all, Han had met the suspect twice.

Because two of them live in a city far away from Shanghai, and there were relatively clear alibi for several incidents, they have been ruled out first. On January 1, the first day of the Lunar New Year, the police organization identified 25 persons listed as key suspects one by one.

After several rounds of identification, the two passengers were clearly identified by three witnesses.The police immediately conducted a comprehensive investigation on the two.

However, the results of the investigation were regrettable. The two men had no time to commit crimes and were quickly ruled out.

At this time, it was already the end of January, and it had been almost two months since the first incident.The case has not been solved, and rumors spread everywhere, and the Shencheng police have been under great pressure.Residents in the suburbs have panicked. Women dare not go out alone or live by themselves. Residential buildings with less than seven floors, especially those on the top floor, are vying to install anti-theft nets on the balconies, so that this kind of business is booming. expensive……

However, the failure to identify the person did not discourage the task force. On January 1, Jiao Yang decided to start the investigation again.

The police rushed to the scene of the crime one by one, conducted an investigation, and re-contacted Han, the owner of the Jiangning mobile phone shop, and the two victims.

After summarizing the opinions of the three people, the task force further refined the murderer's appearance characteristics: he was about 45 years old, about 1.7 meters tall, shriveled and thin, with a yellow and black complexion, and felt like a manual laborer.

The findings are basically consistent with the original.The police checked the passengers again, and the key suspects were still those 15.

At this time, Jiao Yang had an idea, thinking that evidence had been found in the suspect's residence many times, and the suspect's behavior was so weird, maybe his family members had already noticed it and could provide some clues.

Jiao Yang applied to Li Jinsheng to conduct a home visit and investigation on the three suspects who lived in Shencheng City in accordance with the principle of distance.

In order to solve the case as soon as possible and appease the hearts of the people, Li Jinsheng submitted a report to the Municipal Bureau under great pressure.

The Municipal Bureau approved it after consideration, and at the same time suggested to the Lin City police that the two suspects who lived in Lin City should also be investigated for burglary.

In the absence of evidence, Jiao Yang had to lead a team to investigate the opportunity after finally applying for it.

When visiting the home of one of the suspects, Yuan Gang, Jiao Yang accidentally found a hat, which caught his attention.

In many places, the thick warm hat called Lei Feng hat, when pulled down, can cover the head and neck together, only revealing a pair of eyes.

However, in the weather like Shencheng where there is no snow for many years, it seems that this level of warm clothing is not necessary.

Jiao Yang and Yuan Gang's wife, Yan Aizhen, started a "family life".

After questioning, Jiao Yang learned that the couple are from the north, and their hometown is relatively cold. This kind of hat is prepared for shelter from the cold when they return to their hometown.

Jiao Yang pretended to be casual and asked: "Sister, is Brother Yuan going out at night? Do you have a lot of entertainment?"
