The criminal's methods are very cruel. Currently, the police The murderer is being investigated and arrested. The general public must pay attention to their personal safety and avoid going out at night and returning late. According to the testimonies of eyewitnesses, the police drew a simulated portrait of the suspect, and please call the police if they have clues. hotline:……"

On the second day after the third case, this announcement was posted on the Internet platform and broadcast by Nancheng TV Station. Afterwards, Zhuang Yi accepted an exclusive interview, which was continuously broadcast on major radio stations.

On the third day after the third case, in a small fast food restaurant next to a demolished building in Nancheng City, the content of this interview was being broadcast on TV.

The name of this fast food restaurant is Ruyi Restaurant. It is said to be a restaurant, and there are only eight tables in total.

It has been a good year since the small restaurant opened here. The taste is moderate and the price is fair, so the business is not bad, but the environment is limited and the owner has no ambitions, so he uses it to support his family without expanding.

On one side of the yellowish wall of the store, there are full of price tags, and an old-fashioned TV is hung in the corner next to it.

"The recent vicious serial killings in this city have attracted public attention. Here, I would like to remind all viewers in front of the TV to learn about the relevant situation through the police platform and not to believe in rumors."

The host in a black suit turned around at this point and looked at the guests beside him: "Today, we are very honored to invite Professor Zhuang Yi, the police consultant for this case, to conduct an interview with the frontline program of the rule of law in Nancheng. Hello, Professor Zhuang , The general public is very concerned about the progress of the current investigation. Can you reveal some information about this case for us?"

Zhuang Yi, who was sitting by the side, adjusted his glasses with a serious expression, "Regarding this case, I believe that everyone has already known the basic situation and the portrait of the criminal suspect through the announcement on the police platform. As far as is known, the suspect It is aimed at women who return at night..."

……

"Currently there is a saying on the Internet that the police are suspicious based on the profiling and analysis of the murderer and sorting out various clues at the crime scene. There may be two suspects who committed the crime together."

"Well, there is such a hypothesis," Zhuang Yi nodded, "but it's just a mental model analysis based on the scene."

"Then can you give us a detailed analysis, if there are really two murderers, their possible roles in the case."

Zhuang Yidao: "The two murderers, one of them is more violent and insane. He is a male, about 25 years old. He used violent means to attack the attacked women. I personally gave him a code name, Night Owl; One is milder, older, and may be coerced. He usually appears after the murder and helps the victim organize his clothes and makeup. I think this collaborator still has some conscience. The code name I gave him is Night Butterfly."

"Here, let me explain to the audience friends that night owl is another name for owl, which is the owl we are familiar with. In fact, owl is a nocturnal carnivore and is also very ferocious. This name is very appropriate. And night butterfly is a butterfly at night. , there is some mystery. The police released the portrait of the male suspect based on the testimony of eyewitnesses, and asked the audience in front of the TV to provide more clues."

……

"Professor Zhuang, how long do you think the police will be able to catch them? Or let me ask another way, do you think the police can find the murderer before the next victim appears?"

Zhuang Yi adjusted his glasses again: "It's hard to say. The police are currently investigating. I can't say the specific time. I can only say that everyone is doing their best. Of course, everyone hopes that there will be no new ones." The victim appears."

"Then the last question, maybe the murderer is watching our program together in front of the TV, so what kind of message will you send to the murderer through our program?"

"The legal net is full of omissions. I hope the criminals in this case can stop killing and bring them to justice as soon as possible."

"I am very grateful to Professor Zhuang for being able to come to our program to record. I wish everyone eat supper every day and don't encounter night owls. You only live once. Please pay attention to safety. Female friends must be very careful at night and avoid going out alone..."

In a small restaurant, a young couple sitting at table number four watched a program on TV, and the boy began to complain: "According to me, there is nothing safe if you don't go out."

The girl picked up the food in front of her with chopsticks: "You are a straight man thinking, just like that women are not allowed to ride along after eight o'clock. Couldn't it be that male criminals can reduce the occurrence of such things if they manage themselves well?" She tilted her head. I glanced at the TV, and the show was still going on, "However, if I didn't come over for dinner and play this, I wouldn't even know it happened. Old men and women only watch TV."

The boy slandered: "Isn't it because you only hold your mobile phone and computer to watch every day? You don't care about current affairs news at all?"

The girl complained: "I didn't see it on Weibo either. In the final analysis, this matter is still too far away from life."

"It's all on the trending searches, but you haven't seen it yet? You're busy chasing stars every day." The boy said this, and the two of them had almost eaten their meals, and called out: "The boss pays the bill."

Alas, the boss pointed it out: "38 yuan, the payment code is posted on the table."

After the young couple went out, the small restaurant became a lot quieter.

The rule of law program finally finished playing, and the familiar ending music began to play. A young man sitting at table No. 2 in the corner of the hotel stood up, took out a few crumpled banknotes from his pocket, and whispered: "Boss, money It's on the table." His voice was so hoarse that it sounded like he was rubbing sandpaper.

The boss was busy checking Ele.me's orders at the counter, and let out an "ah".

He knew this guest. He was a frequent visitor to the small restaurant. He often sat there, ordered fried rice with eggs when he came in, and kept his head down without saying a word.

I don't know if he is sick, but this guest has a bad throat, a hoarse voice, and heavy breathing. He looks like a young man, but he sounds like an old man in his seventies or eighties.

The young man paid the bill, put on his hat, lowered the brim of his hat, and walked out the door with his hands in his pockets.

Walking in from the entrance of the hotel, two assistant policemen in police uniforms almost passed the young man.They came to the counter: "Boss, have you heard about the latest case?"

Since the case was notified, the police stations of each sub-bureau have received orders from the Municipal Bureau for coordinated investigations. All police officers and co-police officers in the area where the incident occurred have been mobilized to carry out a dragnet on restaurants, shops, companies, and neighborhood committees in the area under their jurisdiction. A detailed investigation was carried out, and patrol cars patrolled at night.

"Oh, I heard, I heard, you can be abnormal." The boss hurriedly rubbed his hands and came out, "Have you caught it?"

"Not yet, how can it be so fast, isn't it working overtime every day?" An assistant policeman said, and took out a wanted poster with a portrait of Song Wenhua on it, "You have met a man like this before here. person?"

The boss frowned and looked at the portrait, feeling familiar, but couldn't remember where he saw it.

"No, I haven't seen it." In the end, he still shook his head and replied hypnotically, "Don't worry, I have never seen any perverted murderers here. How else would I do business?"

"Then be careful." Another police officer handed over a poster, "Here, put one on the front of the counter. Just in case someone recognizes you."

"Okay, okay." The boss nodded and pasted the poster in front of the counter with double-sided tape.

The assistant police said: "If you see it later, remember to call the reporting hotline if you have clues, there seems to be a bonus."

"Okay, you have worked hard." The boss sent the two policemen out, turned around, walked to the No. 2 table, picked up the banknotes on it, and muttered in a low voice, "There are still young people who use cash every day these days." .”

In the Nancheng City Bureau at this time, Bureau Gu specially asked people to clean up the empty room next to the director's office as a special office for this case. Various clue boards were pasted on the wall, and all the materials were piled up in a pile. , set aside for easy viewing.In order to investigate this case, it can be said that several elites from the Nancheng Bureau tried their best.

The broadcast effect of the program was very good, and soon, many reporting hotlines were received, but there was not much valuable information among them.

Just after lunch, the reporting hotline in front of Tian Ming rang again, and he immediately picked up the microphone: "Hi, hello, this is the Nancheng Bureau, do you have any information related to the recent case?" Any clues?"

"...Do you suspect that the next door to your group rental is like that murderer? He peeped at you in the shower?" Tian Ming frowned and repeated, "Uh, that... the murderer seems to have no interest in men for the time being."

The other party said a few more words, Tian Ming nodded: "Well, the height of 185 may not match the murderer... But we will contact the colleagues at the nearby police station and go over to have a look. Please leave us your address and contact information? "

"What? You don't need to go there?" Tian Ming wanted to say something, but the phone became disconnected, "Oh, I hung up."

Song Wen glanced at the dejected Tian Ming, and as expected, the call was a false report.The point is that we have received many such calls.

Team Tian angrily opened the record book, and scratched a few strokes on it: "No. 17 reporting hotline, it's not..."

"It's better than the previous ones. I didn't ask you to make a trip, at least you didn't find out that it's completely irrelevant after passing by." Fu Linjiang said, "We can't just sit and wait like this. What else can we do besides these?"

It had been three days since the incident happened, and apart from the occasional calls to report, they hadn't gotten any new clues, and the whole city was as calm as water.For the elite of the Criminal Police Force, it is too passive now.Moreover, with each passing day, they felt that the sword hanging over their heads had dropped by a fraction.

Sitting aside, Lu Siyu carefully checked the site investigation report of the third case. This was the fourth time he had turned it over and over again. He raised his head from the pile of documents and looked at Song Wen.

Song Wen felt that the longer he waited, the more panicked the people in the room became. He sighed and stood up to call the shots: "Where is that Professor Zhuang? Why haven't you seen him recently?"

Tian Ming said: "Professor Zhuang is a very busy person. He has been recording a program recently, but he said that he will come to our side later. If there is any progress or encounter difficulties, you can also contact him."

Zhang Ziqi said: "Well, I heard him say that he didn't want to go on the show to talk about this case, and it was inconvenient to reveal the details of the investigation, so I thought it was true, but after the approval from the leader, he went on the show, and he didn't say much."

Song Wen raised his head and asked again: "Make sure the portrait has been sent down, right?"

Fu Linjiang spread his hands and said: "Yes, the police from all sub-bureaus and police stations are patrolling the streets, and the portraits about this case are distributed to various neighborhood committees and companies, even the small stalls, but so far there is no effective clue. The murderer doesn't always live in a vacuum, has no relatives and friends, can't meet passers-by, and only comes out to commit crimes at night, right?"

Song Wen thought for a while and said, "We only have one eyewitness, and we don't have photos, cameras or other images. Maybe the characteristics are not obvious enough." He is absolutely confident in his painting skills, but due to limited conditions, a good one The profile picture of the suspect does not necessarily help them catch the murderer.

Lu Siyu said softly from the side: "People have no impression of people they meet by chance, and ordinary people have a kind of misleading thinking, thinking that the people they know cannot be criminals."

The murderer may just be in the blind spot of people's observation.

There are some people around us, people are always the last to think of, students with poor grades in the corner of the class, colleagues who are difficult to mention in the office, they are like transparent people, they are by people's side every day, but the key Sometimes, I can't even remember the name.

Fu Linjiang nodded in agreement: "This murderer must be quiet enough to not attract attention."

Zhang Ziqi thought for a while and asked, "Can we conduct fingerprint screening for men of the right age in the entire area?"

Tian Ming rejected it first: "Do you know how many men of the right age live in this urban area? Moreover, the city is so mobile, and our police force may not necessarily produce results after a few months..."

Song Wen thought for a while and suggested: "But we really can't wait like this any longer, why don't we set up bait. Arrange some policewomen to walk around at night and cooperate with the patrol, it's better than just sit and wait."

Tian Ming became interested when he heard this: "Hey, I like this action, just wait and see. But where can we fortify to hit the murderer?"

Song Wen looked at the map of the Nancheng district hanging on the wall: "According to the theory of circles, we know the scope of the murderer's activities. Every time he commits a crime again, he will avoid the place where he once committed the crime. Such a bustling location, we subdivided the map, divided it into arrays, and set up some ambushes. Then let the female policeman walk around with a communicator."

"Will the murderer take the bait?" Fu Linjiang was a little worried.

Song Wendao: "Not necessarily, but there is no better way now. Try to see if it works. In short, strengthening night patrols can make us a little closer to the murderer."
