Gao Jianguo took two simulated portraits from Ling Hu Yunfei's hands and put them on the computer table: "Wu Dawei, you search again, is there anyone who matches these two people, search conditions, Ling Hu Yunfei, you say." ”

Wu Dawei moved a bench next to him and motioned for Linghu Yunfei to sit down and speak.

"The man was born between 1953 and 1957; The woman's birth year is 1956-1960, and the rest of the search criteria are based on these two simulated portraits. ”

Wu Dawei's added search criteria are: man, face with the word "country", short hair, wide forehead, leopard eyes, flat nose, wide chin; Woman, melon seed face, long hair, phoenix eyes, high nose bridge, pointed chin.

After all the conditions were set, the search began, and a minute later, 797 and 1117 appeared on the computer screen (a total of 797 men and 1117 women who met the set conditions).

Wu Dawei then pasted the simulated portraits of men and women onto the computer through a scanner, and adjusted the size of the simulated portraits on the computer screen to the size set in the search software.

The second step of the search begins, and after 30 seconds, the words 9 and 15 appear at the bottom of the screen (9 and 15 people are more similar)

Wu Dawei compared the nine and fifteen people with the simulated portraits one by one, causing Hu Yunfei, Xiang Daimo and Lin Di to look intently at the computer screen, and a pair of avatars flashed on the computer screen every few seconds, one of the avatars, that is, the simulated portraits, were always the same, changing the heads of nine people and fifteen people.

Wu Dawei saw the problem from the eyes and expressions of the three people: "Captain Liu, how is the simulation of the simulated portrait?" ”

"The degree of simulation is very high, and when we show the simulated portrait to several important parties for identification, they recognize the person on the simulated portrait at a glance, and these two simulated portraits are no different from the impression in their memory."

Linghu Yunfei also had questions: "Captain Gao, how should this similarity be understood?" ”

"Xiao Wu, you can answer this question."

"Captain Linghu, the situation is like this, this software is completely limited by the conditions given, and the similarity can only be a reference, if there are omissions in the given conditions - especially some important omissions, then, there will be problems with the answers given."

All in all, there is a certain gap between the answer and the real person. There is still a certain distance between the simulated portrait and the real person, and it is normal to omit some important information. The conclusion drawn by such software can only be used as an auxiliary means, and it has the advantage of locking the parties within a certain range. ”

"So be it!" Gao Jianguo slapped the table, "Wu Dawei, you make a copy of the one that is relatively close to the similarity, and then attach the household registration information." When we have time, we'll ponder it slowly. Captain Linghu, let's go to the Second People's Hospital now, tonight, we can find Huo Siwen, this harvest is not small. Gao Jianguo had the meaning of comforting Ling Hu Yunfei.

After several traffic lights, the car stopped in the parking lot in front of the outpatient building of the Second People's Hospital.

At the entrance of the outpatient building, there is an information desk.

Under the guidance of the nurse at the information desk, the four of them walked through the three buildings and got on the elevator in Building 8, the hospital is relatively large, and if you want to know about Huo Siwen's situation, you must go to the personnel department of the hospital.

Unfortunately, the door of the personnel department was closed, and Gao Jianguo led three more people to the dean's office, where there was a leader on duty, Assistant Su.

Assistant Su is relatively young, and he doesn't look to be more than thirty years old.

When Gao Jianguo explained his intentions, Assistant Su said: "I'm sorry, I haven't been transferred here for a long time, I'm just an assistant to the president, and if you want to know the situation of the hospital staff, you have to find the personnel department." So be it! I'll call Director Hao from the Personnel Department, and you can wait a minute. The other person picked up the phone.

About forty minutes later, a woman about fifty years old walked into the duty room, she was Director Hao of the Personnel Department.

After Ling Hu Yunfei explained his intentions, Director Hao stood up: "Huo Siwen did work in the dental department of our hospital, there are two dental hospitals in this city, and there are relatively few people who come to the dental department of our hospital to see a doctor, so the number of visits to the dental department of our hospital has not been able to go up, and later, Huo Siwen resigned from his job here and opened a dental clinic by himself, do you want to know more about him?" ”

"Director Hao, I'm sorry for your trouble." Linghu Yunfei said.

The three of them said goodbye to Assistant Su and went to the inpatient department on the tenth floor with Director Hao.

A female comrade about forty years old received Director Hao and everyone.

This woman's surname is Jiang, her name is Jiang Xiaoyan, she is Huo Siwen's graduate of the same class as Shanghai Medical University, and the two of them were assigned to Shanghai Second People's Hospital together.

Although Huo Siwen resigned, he still had contact with Liang Xiaoyan, who often introduced some patients to Huo Siwen's clinic.

Director Hao brought his comrades to find Liang Xiaoyan, which is the right one. Liang Xiaoyan is very familiar with Huo Siwen's situation. Director Hao said that shortly after Huo Siwen's resignation, his wife also left the hospital.

Liang Xiaoyan wrote Huo Siwen's message on a piece of paper.

It reads as follows:

Home address: No. 307, Unit 1, Lane 13, Wenhui Road, Zhabei District - this is the same information as the information on the household registration file.

Clinic address: No. 287, Bansongyuan Road.

In addition to the information on the paper, Ling Hu Yunfei also wanted to know more about the situation: "Doctor Liang, what will Huo Siwen's wife do after she resigns?" ”

"Since Hosven opened the clinic, the economic conditions have been getting better and better, so Perrin - Perrin is Hosven's wife - she later became a full-time wife."

"Do you know that Hosven passed on to his aunt?"

"I don't know, he never mentioned it, and his classmates only knew his mother's surname."

"You and Hosven studied together, worked together, and now have a close relationship with him, so you should know his personality well."

"As his name suggests, he was an introvert and a man of few words, but he was a very intelligent man, a visionary, a very shrewd man — when he resigned, we didn't understand it, and it turned out that he was right — and now the couple is living a good life."

"What year did Hosven resign?"

This is a very important question, and if Hosven had resigned after July 1986, it is unlikely that he would have had two months of long vacation. Even with such a long vacation, it should be on file.

"Hosven resigned in 1987. I can't remember exactly what time it was. ”

"There's no problem with that, I'll check the original file to find out." Director Hao said.

The understanding of Hosven can only go so far.

When he broke up with Liang Xiaoyan, Linghu Yunfei told Liang Xiaoyan not to investigate his matter with Huo Siwen and his comrades, and Liang Xiaoyan agreed.

After that, the three of them went to the personnel department with Director Hao.

Two minutes later, Director Hao found out all the formalities when Huo Siwen resigned from a large stack of materials.

Director Hao took out a resignation report, which clearly stated the time of resignation: "May 3, 1987. ”

Linghu Yunfei asked Director Hao to check Huo Siwen's attendance from May to July 1986. As a result, Hosven had no record of taking long leave during this period. The attendance record shows that you are coming to work as normal. Director Hao said that because of the particularity of the hospital's work, it can only be taken in shifts, and the time of rotation is not more than two days (except for special circumstances).

After leaving the hospital, Gao Jianguo accompanied the three of them to No. 307, Unit 1, Lane 13, Wenhui Road, Zhabei District. Now that he has come to Shanghai, it is still necessary to meet with Huo Swen and his wife. When she broke up with Liang Xiaoyan, she told everyone that Huo Siwen's clinic would close at 6 p.m.

Hosven's family lives in an old European-style building. The author would like to emphasize two things here: first, among the 9 and 17 people searched by Wu Dawei, there were no Huo Siwen and his wife; Second, the photos of the couple do not match the simulated portraits at all, which can be seen by the eyes.

So, why did Linghu Yunfei go to Huo's house?

Linghu Yunfei has three considerations:

First, Huo Siwen is a dentist, Xiao Lao's prompts made Hu Yunfei dare not forget, and Ling Hu Yunfei, who has always been careful, still has a glimmer of hope. In criminal investigation work, as long as there is a glimmer of hope, we cannot give up easily.

Second, the murderer was an orthopedic surgeon, at least a dentist, and his modus operandi was very sophisticated, which made it necessary for Hu Yunfei to ask Huo Siwen for some technical questions.

Third, seeing is believing, especially when handling cases. It is too hasty and subjective not to meet with Huo Swen and his wife, and directly exclude Huo Swen and his wife from the sight of their comrades.

As Liang Xiaoyan said, Huo Siwen and his wife are indeed living a very nourishing life, which can be seen from one aspect.

When the comrades walked downstairs to Hoswen's house, they were confronted by a man who hurried downstairs, carrying a black leather bag in his hand.

"Who are you looking for?"

This person saw Gao Jianguo looking at the house number.

"May I ask if this is a unit in Lane 13?"

"Not bad. Who are you looking for? As he spoke, the man pressed the car key in his hand, and the lights of the car parked not far away flashed a few times.

"We're looking for Dr. Huo."

"Do you have anything to do with him?" As he spoke, Hosven looked at the four people, he should have seen the uniforms on the four people clearly, "You are-"

"I'm from the Shanghai Municipal Public Security Bureau, and these three are from the Jingxi Municipal Public Security Bureau, and they want to ask you a little bit about the situation. Are you out on business? ”

"I just received a phone call from a patient who was rolling on the couch with an unbearable toothache and was getting ready to go to the clinic. So be it! You come with me to the clinic to see a doctor and investigate. ”
