,PS:It's all big chapters now.,See enough.,Everyone has a variety of tickets to support it!

Lu Yun glanced at Lin Lei with some expectation, and asked in a low voice, "Who are we investigating first?"

Lin Lei thought for a moment and replied, "Beauty salon." ”

Fujimoto's eyes lit up, and he asked excitedly, "The first person Detective Lin wants to investigate is Ryoko Hirota?"

According to the idea of solving the case by the police, the suspects are divided into three, six, nine and so on, and the investigation generally starts with the most suspicious person.

The reason is very simple, solving a criminal case is not exactly the same as solving a puzzle, solving a puzzle doesn't matter who investigates first, anyway, you can solve the puzzle in the end.

But solving a case is different.

The suspect has always been a living person, not a pawn.

If you don't check the major suspects, go to the ordinary suspects first-

So even if the puzzle is solved, what happens if the major suspect escapes?

What if the suspect destroys the evidence?

There are too many unpredictable factors in this, and we must pay attention to the word "fast" to solve the case.

Of course, Lu Yun knew the thoughts of the Fujimoto Police, and she explained with a smile: "These people are not extremely vicious bandits, and they have been placed under surveillance by the police of the Tokyo Metropolitan Police Department, and they can't run away if they want to." It's also unlikely that they will continue to commit crimes under police surveillance, so there's no point in who we investigate. ”

After a pause, Lu Yun continued: "We haven't met these people, and in Lin Lei's style, he must meet the suspects one by one." ”

"Hi Yi—" Fujimoto replied in a low voice, indicating understanding.

The first place Lin Lei chose to investigate was the beauty salon in Luqi Town.

Everyone soon drove to the beauty salon.

The beauty salon is located about two kilometers from the apartment at the scene of the crime, on a street that is not too wide.

After getting out of the car, Lin Lei first observed the surrounding environment and found that it belonged to a very ordinary commercial street, with various commercial shops.

There is only one beauty salon on this street, and there are more restaurants such as ramen restaurants and sushi restaurants.

The food culture of this book is different from that of China, and it is especially evident in Tokyo.

There are more restaurants that resemble fast food, and the main reason is that the work in Tokyo is relatively stressful and fast-paced, and ordinary people eat fast food such as ramen or sushi when they eat out.

Lin Lei was in front, and everyone else followed behind him.

When he arrived at the beauty salon, Lin Lei asked the Fujimoto police to go and say hello to the people inside first, asking for cooperation with the investigation.

Some people are always happy to introduce their identity, but Lin Lei doesn't care about these at all, but feels very troublesome.

Seeing the Fujimoto police walk into the beauty salon, Lin Lei frowned slightly, as if he was thinking about something important.

The beauty salon store is not large, with a total of two floors.

The first floor is mainly for ordinary beauty projects, while the second floor is for some more high-end projects, such as projects that require beauty machinery and equipment, all on the second floor.

The Fujimoto police officer showed his ID, and the beauty salon owner immediately followed him with a smiling face respectfully.

The boss was waiting for the Fujimoto police to ask, but he was surprised to find that the Fujimoto police had walked out of the beauty salon with a more humble attitude than him and welcomed three people in.

The leader is naturally Lin Lei.

The salon owner is a somewhat balding man in his early forties, while his wife is grooming clients in the shop.

Apparently the boss was in charge, and it was her wife and other employees who were in charge.

Lin Lei glanced around the beauty salon and quickly withdrew his gaze.

It's afternoon, there are three customers in the store on the first floor, and there are not too many people in general, and there are probably some customers on the second floor.

Lin Lei pointed to the sofa on the side of the beauty salon and motioned for everyone to go there and sit down and talk slowly.

Soon everyone sat down, and the boss made tea for everyone.

Lin Lei took a shallow sip of tea, then stared at the beauty salon owner for a full minute before slowly asking, "What's your name?"

The beauty boss looked stunned and immediately replied, "Officer, my name is Yamagata Ryojin." ”

Lin Lei bowed slightly, and then asked, "Mr. Yamagatata, do you have many VIP users in your beauty salon?"

Yamagata Ryojin nodded and replied: "Our beauty salon is mainly a business for repeat customers, because in our VIP usually is 20% off, and on member days is 5% off, so more than half of the customers have handled VIP membership. ”

The "routine" of doing business all over the world is the same, and this beauty salon gives discounts to VIP members in order to keep customers in their own stores, which is also a very common marketing method.

At this time, Lin Lei did not continue to ask, but looked at the beauty salon again, and Lu Yun, who was sitting on the side, asked, "Mr. Yamagatata, are you familiar with Miss Ryoko Hirota?"

Of course, Yamagata Ryojin knew that these policemen must have come to inquire about Ryoko Hirota, and he was mentally prepared, so he replied directly: "Yes, officer." Ms. Ryoko Hirota was a VIP member who opened in our store about three years ago, and she has been doing beauty treatments with us regularly for several years. ”

After a pause, Ryoma Yamagata continued: "Miss Ryoko Hirota arrived at our beauty salon at 9:35 that day, she was doing a body shaping project, and she needed to use the instruments and equipment on the second floor, and the whole project lasted about two hours, and Miss Ryoko Hirota left us at about 12 o'clock at noon. Because there is a surveillance video at the entrance of the beauty salon, the time when she enters and exits can be checked at a glance, and in the beauty salon, there are employees who accompany Miss Ryoko all the time......"

Obviously, Yamagata Ryoma has been questioned by the police many times, and each time it is naturally a strict scrutiny of the time when Ryoko Hirota enters and exits, and he already remembers it very familiarly.

Since there is surveillance to prove it, and there are always employees accompanying her during the beauty salon's beauty treatment, it seems that Ryoko Hirota's whereabouts after 9:35 can be confirmed.

These situations have naturally been investigated by the police many times, and there should be no mistake, you must know that I am still relatively rigorous.

Lu Yun set his eyes on Lin Lei, and Lin Lei glanced at Yamagata Liaozhen, took over the topic, and continued to ask: "Mr. Yamagata, what kind of projects does Miss Ryoko Hirota usually do in your beauty salon?

Yamagata Liaozhen was stunned, Lin Lei's question had never been asked by the police, and after a little thought, he got up and went to the service desk to get a laptop.

There were accounts of the entire beauty salon in the laptop, and Yamagata Ryojin found Ryoko Hirota through the VIP inquiry system, and pointed out her consumption details to Lin Lei.

Lin Lei looked at it carefully, and probably counted it in his heart, it turned out that the money that Ryoko Hirota spent on the beauty salon every month was about 70,000 yen.

Lin Lei immediately turned his head and asked Fujimoto Police, "What is Ryoko Hirota's monthly income?"

Fujimoto scratched his head and said hesitantly: "An ordinary company clerk like her, if she is in her twenties, it should be more than 200,000, right?"

Lin Lei was a little dissatisfied, and his tone increased a little: "I don't want to listen to the word 'should', you immediately call Guangtian's company to ask!"

"Hi Yi!" Fujimoto stood up with a snort, immediately took out his mobile phone, and started calling.

The first call was made back to the police station, and the relevant personnel were asked for the phone number of Hirota Ryo's company, and then the second call was made.

After some questioning, someone from Ryoko Hirota's company told Fujimoto that Ryoko Hirota's monthly salary was 220,000 yen after tax.

After getting the exact answer, Lin Lei's eyes narrowed slightly, and he didn't know what he was thinking......

Lu Yun vaguely knew what Lin Lei was thinking, so he asked Fujimoto Police: "How much is the cost of living for a person like Ryoko Hirota?"

Fujimoto thought for a moment and replied, "The first expense is the rent of the house, and the monthly rent of Ms. Akiike's apartment is 60,000 yen, and the rent is relatively cheap for a 15-square-meter single room with a bathroom. Water, electricity, and natural gas bills are normally about 20,000 yen. It's hard to say about the phone bill, but it seems that the previous investigation did not find any abnormalities in Ryoko Hirota's phone, so it is about 10,000 yen by ordinary standards. ”

After thinking about it carefully, Fujimoto continued: "In Tokyo companies, we usually pay for weekday lunches by individuals, and according to the relatively cheap way of eating, it costs about 20,000 yen a month. It's hard to say that you can make your own breakfast and dinner, but at least 20,000 yen on a normal level. The transportation fee is relatively easy to calculate, and Ryoko Hirota commutes to work by public transportation, which costs about 10,000 yen a month......"

Without waiting for Lu Yun to speak, Qiao Yan on the side quickly calculated the answer: "In other words, Ryoko Hirota needs about 140,000 yuan for basic living expenses alone." She can't go shopping, she can't buy things, she can't have all kinds of entertainment and pastimes—if she has a salary of 220,000 yuan, she still has 80,000 yen in surplus, and she spends 70,000 yen of this 80,000 yen on beauty ......"

Lu Yun shook her head and said with a smile: "How can a girl not spend any pocket money? It seems that Ryoko Hirota is a real moonlight clan, and the remaining 10,000 yen will go out shopping with friends casually, and if you eat something, it will be gone." ”

Qiao Yan nodded and agreed: "Well, it should be like this, anyway, the money is definitely not enough to spend." ”

Lin Lei didn't speak, and everyone turned their eyes to him, wanting to hear what he thought.

Lin Lei glanced at everyone, but did not express any opinion.

Then Lin Lei took everyone up to the second floor and carefully checked the situation on the second floor of the beauty salon.

There are a total of six or seven small single rooms on the second floor, each with different beauty equipment and different beauty items.

There was only one client on the second floor doing photorejuvenation, and the other rooms were empty.

Lin Lei entered the body shaping project room where Ryoko Hirota was that day, and the furnishings inside were very simple, in addition to the body shaping equipment, there was a small table and two single sofas.

After Lin Lei checked it, he didn't mean to leave, but suddenly turned his head and asked Yamagata Ryozhen: "Who is the employee who accompanied Ryoko Hirota to do beauty that day?"

Lin Lei's words were obviously asking Ryoko Hirota about the time witness, and Yamagata Ryozhen immediately replied: "It's Xiaoyou." ”

Lin Lei squinted his eyes slightly, and said lightly: "You called her." ”

Yamagata Ryoma immediately went downstairs and called the employee Xiaoyu over.

Xiao Yu's full name is Yu Katayama, about 20 years old, with a medium build, about 1.60 meters tall.

She has long hair and an ordinary appearance, she can't say that she is beautiful or beautiful, she is just an ordinary working girl.

Xiao You came to Lin Lei, lowered his head, looked a little restrained, and kept fiddling with the corners of his clothes with his hands.

Lin Lei glanced at Xiao You and said slowly, "You raise your head." ”

Xiao You raised his head and looked at Lin Lei, but quickly lowered his head again.

Ryoma Yamagata on the side explained: "Xiaoyu is more shy, and we are all in the business of female customers here-police officer, maybe she is a little scared. ”

Lin Lei smiled slightly, indicating that he understood.

This kind of ordinary working girl, who has never seen much of the world, suddenly faces the questioning of the police, and it is normal for Xiaoyou to appear.

"What kind of person is Ryoko?" Lin Lei asked directly.

Xiao You was stunned for a moment, and immediately raised his head and looked at Lin Lei in surprise.

Originally, she thought that Lin Lei would ask "technical" questions such as Miss Ryoko Hirota's entry and exit time, but she never expected Lin Lei to ask her this question.

Xiao You didn't want to think about it, so she blurted out: "Miss Ryoko is very good, I can talk to her more ......"

Yamagata Ryojin also smiled and said, "Every time Miss Ryoko comes to our beauty salon, she designates to find Xiaoyu to do beauty for her. ”

Lin Lei bowed slightly, and then asked, "How long have you known Miss Ryoko?"

Xiao You replied directly: "Three years." I came to work at a beauty salon three years ago, and for the first time, I officially served a customer, and the customer at that time was Ms. Ryoko. ”

Lin Lei glanced at Xiao You, and quickly asked again, "Are you from Tokyo?"

Xiao Yu shook his head and replied, "My hometown is from Hiroshima......"

Yamagata Ryojin suddenly remembered something, and blurted out: "Miss Ryoko is also from Hiroshima, and she and Xiaoyu are fellow countrymen, so they can talk very well." ”

Lin Lei's eyes narrowed slightly, nodded, and was noncommittal.

At this time, Lu Yun and Qiao Yan glanced at each other, and their lips moved, as if they wanted to say something at the same time, but they didn't say it.

Fujimoto scratched his head, looking at this, and then at that, with a bewildered expression......

After a long time, Lin Lei suddenly said, "OK, that's the end of today's investigation." ”

Lin Lei glanced at the beauty salon owner Yamagata Liaozhen, quickly retracted his gaze, and said to Lu Yun, Qiao Yan and Fujimoto Police, "Let's go." ”

After coming out of the beauty salon, Lin Lei, Qiao Yan and Lu Yun all lowered their heads and thought about their hearts, and never spoke.

Fujimoto wanted to ask a few times, but seeing everyone thinking separately, how dare they bother?

Finally walked to the front of the police car, and the Fujimoto police opened the rear seat door for Lu Yun and Qiao Yan, and then opened the passenger door for Lin Lei, and then asked cautiously: "Detective Lin, where are we going next?"

Lin Lei glanced at the Fujimoto police at this time, and his eyes were a little deep: "The next stop? Hmm, this stop is not over yet!"

"Ah?——h

Lin Lei said coldly: "The surveillance video of Ryoko Hirota's entry and exit, has the Tokyo Metropolitan Police Department backed it up?"

Droplets of sweat the size of soybeans immediately appeared on the head of the Fujimoto policeman, and he said resignedly, "Uh-this...... This ......"

"Hmm, what? no?" Lin Lei raised his tone a little.

Fujimoto wiped his sweat and said in a low voice: "At the beginning, because the first suspect in the case was Zhao Yi, the priority of investigating other suspects was not so high. The surveillance video must have been seen by a police officer, but it was not copied to the Metropolitan Police Department......"

After a pause, Fujimoto explained in a quieter voice, "Please also ask Detective Lin for your understanding." Under normal circumstances, only the relevant video surveillance of major suspects will be copied, and we can check the videos of ordinary people. It would be too ...... if all the surveillance video of each subject of the investigation had to be copied back to the Metropolitan Police Department."

Lin Lei pondered for a while, and this is also the reason - if all the videos of each investigation subject are copied, so many criminal cases occur in Tokyo every day, how big a computer room must be repaired, and how many hard disks will be prepared to be enough to install?

"You go and copy Ryoko Hirota's comings and goings to your laptop right now. Lin Lei pointed to the working computer used by the Fujimoto police on the police car and said solemnly.

Fujimoto immediately responded: "Hey, whoa, Mahida!" (yes!mine, understood!)

Subsequently, the Fujimoto police officer immediately picked up the laptop and trotted back to the beauty salon.

Looking at the back of the Fujimoto police officer entering the beauty salon, Lu Yun asked in a low voice, "Lin Lei, do you suspect it-"

Qiao Yan also said at the same time: "BOSS, do you think she ......?"

Lin Lei glanced at the two of them and said with a smile: "I don't think anything." ”

Lu Yun immediately glared at him and said hatefully: "King Guanzi, you started again-"
