"Scorpion has a great background?" Lu Weiwei looked at Zhao Guozhi with a puzzled look.
Perhaps because of her short time as a police officer, in Lu Weiwei's memory, she has never heard of a person named "Scorpion".
But Lao Wang is different. Lao Wang is an old comrade.
What's more, a veteran policeman like Zhao Guozhi must know more.
Zhao Guozhi coughed twice and couldn't help but said: "I should have an impression of this scorpion."
"Back when I was a young police officer, when I was working on cases with Bureau Qin, I once met this guy named 'Scorpion'."
"It's just that at that time, Scorpion was just a young man of the same age as me, and in the blink of an eye, I was no longer a teenager."
"Bureau Zhao, what does this 'scorpion' you are talking about have to do with you?" Gu Chen could tell that Zhao Guozhi could make a trip in person.
It can be seen that this so-called "scorpion" character has special significance to Zhao Guozhi.
Zhao Guozhi took the tea made by Yuan Shasha and then said: "To talk about this scorpion, we have to go back to when I first joined the police."
"At that time, we had an important folk culture festival in Jiangnan City, and the organizer was Hu Caixia, who was the director of the Academic Affairs Office of Jiangnan University of Technology."
"And she was also famous for organizing the folk culture festival in Jiangnan City every summer. She was also well-known in the academic world. She lived in the ancient Jiangnan Academy at the time."
"Jiangnan Academy?" After hearing Zhao Guozhi's words, Gu Chen was a little confused and said, "I know that place, but that place is a scenic spot, how can people live in it?"
"That's now." Seeing that although Gu Chen knew about Jiangnan Academy, he didn't know the previous situation of Jiangnan Academy, he quickly explained:
"In our time, how could we have the concept of a scenic spot? Jiangnan Academy, in the ancient Jiangnan City at that time, was just an ancient building."
“It’s also close to the Civic Park, so living there can be said to be a life like a fairy.”
"The owner of this academy was once a celebrity in Jiangnan City. Later, after his death, he donated the academy as a cultural relic to the Park Management Office."
"At that time, Hu Haixia rented the upper room of this academy."
"So it turns out that Jiangnan Academy can still be rented out?" Officer Wang thought thoughtfully and said in surprise: "I never thought about it."
Lu Weiwei also nodded silently and continued to ask: "But what does this have to do with scorpions?"
"Don't worry, listen to me and tell me slowly." Seeing that Lu Weiwei was eager to know the situation of Scorpion, Zhao Guozhi did not tell him immediately, but spoke slowly.
"I remember it was 20 years ago. At that time, a murder occurred in Jiangnan Academy, and the person who was killed was Hu Haixia."
"Hu Haixia was killed?" After hearing Zhao Guozhi's words, many old and new police officers looked at each other.
For this era, many police officers have never experienced it, let alone understand it.
Especially since Zhao Guozhi was just a newly recruited police officer back then.
Zhao Guozhi nodded silently and continued: "At that time, I remember that Jiangnan Academy had just been restored and it was located deep in the park. It was a beautiful Jiangnan courtyard."
"The reason why Hu Haixia rented the house here is probably because she felt that it was a very glorious thing to be able to tell others that she lived in Jiangnan Academy."
"And when we investigated this case, we found Hu Haixia lying naked on the bed."
"Her head was almost cut off, and there were many wounds on her chest. These wounds were not fatal, but were just small stab wounds, like marks left by torture."
"So cruel?" After hearing what Zhao Guozhi said, Lu Weiwei frowned slightly, feeling that the murderer's method of committing the crime was too cruel.
Zhao Guozhi took a sip of tea and sighed quietly: "Back then, when I was working with Bureau Qin on a case, it was the first time I saw such a tragic corpse. I almost vomited."
"And I still clearly remember that at that time we also noticed that Hu Haixia's wrists were tied with some kind of plastic telephone wire."
"And there were still blood stains on the headboard and the wall above it."
"The murderer brutally severed one of her arteries. The bed was soaked with blood, but next to her were the clothes she wore that night. They had not been turned over, and the magazines at the foot of the bed had not been moved."
After hearing Zhao Guozhi's remarks at the scene and restoring the original crime scene, Gu Chen put forward his own opinion based on the only clues:
"If this is the case, does it mean that Hu Haixia did not struggle at the time, but the murderer completely controlled her and tied her up, but Hu Haixia was unable to resist at all?"
"That's right." Zhao Guozhi nodded slightly and agreed, "The results of our investigation at that time were also the same."
"We believed at the time that the murderer did not take anything from the room, and Hu Haixia lived alone, so it was difficult to determine whether she had lost anything."
"But her purse was lying on the dining table outside and her keys were still there."
After a pause, Zhao Guozhi added: "We divided the work on the case investigation at that time."
"Our current Bureau Qin was the person in charge of the entire case back then. I was just his deputy, responsible for recording the scene, making written records of the scene, describing the location of each evidence, and collecting the evidence."
"And I still remember at the time, I was assigned to draw a scale drawing of the entire house."
"Then the colleagues responsible for interrogation will conduct interrogations of relevant personnel, visit and verify vehicle license plates, etc."
"Because the conditions of the Jiangnan City Police Station were limited at the time, Bureau Qin called the provincial crime detection laboratory and immediately evacuated the house to avoid destroying any evidence."
"After that, I worked with people from the provincial crime laboratory, and the work I did was the same as when I prepare written records of the scene now, which was mainly to describe all the situations at the scene."

pot."
"Because there were some unwashed bloodstains there, and the bloodstains were very light because it was clear that the murderer had tried hard to wash them off, but had not succeeded."
"I also recorded these clues one by one, and at that time we also found that there might be a fingerprint on the cold water faucet."
"Of course it's an incomplete print, but we don't want to take fingerprints at the scene and take the tap back to the crime lab."
"What about coming back? Have your fingerprints been taken?" Gu Chen asked.
Zhao Guozhi nodded silently: "Yes, we later found a fingerprint on this faucet."
"Up to that point, all the investigation work was progressing smoothly, so we all left the scene."
"But later, because the headline news of "Murder at Jiangnan Academy" appeared in the newspaper, everyone in our department was harassed by the media."
"In addition, the murderer was not found for a long time, so during that period, each of us felt extremely stressed."
"That's right." Officer Wang understood Zhao Guozhi's difficulties and echoed, "The lethality of news newspapers back then was also very huge."
"A murder case that can be reported should attract a lot of attention. I also remember that I heard it from my elders, but I don't know what happened next."
"This matter is very sensitive, and the deceased was an educator and a local celebrity, so the investigation was very stressful," Zhao Guozhi said.
Lu Weiwei asked again: "What was the direction of your investigation at that time? Did you start with acquaintances?"
"Yes, we just start with acquaintances." Zhao Guozhi did not deny Lu Weiwei's view, but also agreed very much:
"Our investigators at the time focused their attention on an acquaintance of Hu Haixia."
"Because at that time, that is, before the incident, he visited the victim Hu Haixia and then went to the capital."
"At that time, our case investigation was restricted by some criminal investigation techniques, and progress was very slow."
"Many of our police officers at that time believed that Hu Haixia's acquaintance was the murderer."
"But unfortunately, the fingerprint we found at the scene did not match his."
"Later, we had no choice but to send the fingerprint sample to the fingerprint identification system of the provincial department for comparison."
"But we all thought at the time that we could rely on this database to be connected to the national database, but in fact this was not the case."
"Therefore, this fingerprint has been stored in the provincial department's system for many years, waiting for a matching fingerprint to appear, but the search scope is limited to the province."
"What a pity." After hearing Zhao Guozhi's words, Gu Chen shook his head repeatedly.
It is indeed a fact that the database back then was imperfect.
But Gu Chen also wanted to know the further progress, so he continued to question Zhao Guozhi.
"Director Zhao, what happened next?"
"Then?" Zhao Guozhi's expression paused for a moment, and then he added: "Later, because there were no matching clues, many years passed, and this became an unsolved case."
"Is there no clue at all?" Lu Weiwei asked, feeling that this case was indeed difficult.
After all, every era has its mark.
Just like back then, there were very few surveillance cameras on the streets.
The level of various criminal investigation technologies is still very backward. Therefore, if you want to solve the case quickly and there are no clues to support it, the investigation of the case will be very passive.
Zhao Guozhi shook his head and sighed: "I was very young at that time and wanted to solve the case quickly. I could also feel the pressure of Bureau Qin at that time."
"But then, every once in a while, some clues about this case will appear, and then we will look for relevant information."
"Later, my partner, Bureau Qin, who was responsible for the investigation of the entire case, was transferred to the Beijing Administration College to study. As a result, a lot of work on this case came to a standstill."
"Among the people who were initially involved in the investigation of this case, I am the only police officer who is still investigating the case, but all the clues have not led to any results."
"But a few years later, I remember one spring, the case investigation team of the city bureau called me and asked me to investigate this case again with them."
"Because I was very familiar with this kind of case, I went back and redid the work they had already done."
"That is, visiting the friends of the victim Hu Haixia, the people who were with her on the night of the murder, and the people who attended a party she attended before she was murdered."
"Some of these people have passed away, and some have moved to other provinces."
"But DNA technology is very advanced now, because in the past we always thought that the DNA samples we found at crime scenes were not good enough."
"Because at that time, after committing the murder, the murderer turned on the electric blanket on the victim Hu Haixia's bed."
"At that time, Hu Haixia's body was lying on that bed. Everyone believed at the time that the DNA in the sperm found at the scene had no use value and that it had probably been destroyed by the electric blanket."
After a pause, Zhao Guozhi added: "But later we discovered that this was not the actual situation."
"We took the sample back and sent it to the laboratory again, and the provincial laboratory then sent it to the merged DNA database, which is the national DNA database."
"At that time, we were extremely excited because we found matching DNA, and this DNA came from Haidong City, where Haidong Airport is located."
Hearing Zhao Guozhi's words, Gu Chen frowned and quickly asked: "Bureau Zhao, since the matching DNA has been found, does it mean that a similar case has occurred in Haidong City?"
"You're right." Zhao Guozhi shook his finger and said in a positive tone: "At that time, a stewardess was killed in Haidong City."
"And the way he was killed was almost the same as Hu Haixia."
"But after our investigation, we found that because the stewardess was relatively young, the murderer was not able to subdue her as quickly as he subdued Hu Haixia."
"The flight attendant resisted, so the knife left a defensive wound on her right hand, but her head was almost cut off."
"Eh!" After hearing Zhao Guozhi's words, Lu Weiwei couldn't help frowning: "This is too cruel. How perverted is this murderer?"
"You have become a murderer, how normal can you expect the murderer to be?" Officer Wang also joked, and then asked: "By the way, Director Zhao, what is going on with this case?"
Zhao Guozhi tried his best to think back and then said: "This case happened in a hotel next to the airport. The victim had just completed his flight duty that night."
"According to the investigation at the time, it was found that she was a temporary substitute for another flight attendant to fly on that flight, but no one knew that she was staying at the hotel where the accident occurred."
"But she didn't show up for her flight the next day, and the story was eventually revealed when someone checked the room she was staying in and found her body there."
"But during our investigation, we found that the night before the accident, a male flight attendant who was staying in that hotel saw the flight attendant from the window of his room."
"In the parking lot, there was a man walking towards his orange car carrying a special airline suitcase. He thought the man was also a flight attendant."
"But after this case occurred, Hu Haixia's son saw relevant reports in the newspaper, so he decisively contacted the police station in Haidong City."
"He told the Haidong City police at the time that this case looked very similar to the murder case of his mother that had occurred in Jiangnan City a few years earlier."
"But because he contacted the police officer in Haidong City on the phone and did not explain it clearly, and the police officer was not in charge of the case at the time and was off duty, so he was negligent, and in the end the matter was not resolved.
That’s it.”
"That's such a pity." Gu Chen shook his head and sighed: "If the Haidong City Police compare the scene photos of the two cases, then they will know that the murderer may be the same person.
"
"Yes." Lu Weiwei also agreed: "It's obvious, the modus operandi is very similar."
"No way." Zhao Guozhi shook his head and said truthfully: "There are always some people who are not that attentive to work. They only care about their own affairs, so they missed this important clue."
"But then they stopped contacting Hu Haixia's son, and we finally found the matching record in the database."
"We knew at that time that this was the same guy who killed two women in almost the same way."
So since then, we have taken oral swab samples from everyone we interviewed, including the victim's close friends, enemies, and even the women involved."
"Because the task force established at that time had members from the provincial crime laboratory, our samples were processed with priority."
"And within a few days, we had the information we needed."
"Although both cases became cold cases, when we found matching records in the database, investigators from both cases sat together."
"I checked the fingerprint record again at the crime laboratory and realized that the record had only been entered into the provincial department's automatic fingerprint identification system and had never been sent to the national database."
"So I immediately submitted the fingerprint to the person in charge of the laboratory, and then we found a matching record in the fingerprint database."
"The fingerprint extracted at the scene matched the fingerprint left by a man named He Xizhou when he was arrested in Jiangbei City a few years ago."
"This man named He Xizhou has entered other people's rooms many times and stolen women's underwear and bras in Jiangbei City."
"Not only that, he was also arrested in other places. Later, he returned to Jiangnan City and started working at the sprinkler system company where his father worked."
"And this company also happens to have provided services to Jiangnan Academy."
"Because four days before the murder, this man named He Xizhou and several other people from the company came to Jiangnan Academy."
"Because it was getting colder, they turned off the sprinkler system there to prevent it from freezing."
"The control facilities of this system are located underground in Hu Haixia's room."
When he saw everyone staring at him intently, Zhao Guozhi also said truthfully: "We were sure at that time that he should be the murderer."
"So there are his fingerprints at the scene, and he may have the opportunity to enter the scene, and he may have met Hu Haixia."
"Because Hu Haixia has no curtains on her bedroom window, and there is a parking lot opposite Jiangnan Academy."
"People often say that they saw Hu Haixia lying there naked, and she did not shy away from tourists outside."
Seeing that everyone was ashamed of Hu Haixia's "openness", Zhao Guozhi added: "Let me tell you this, from my understanding, this Hu Haixia is not afraid of her body being exposed."
"And we are really convinced that He Xizhou is the murderer, but we still have to compare his DNA with the DNA found at the scene."
Gu Chen nodded silently and asked Zhao Guozhi: "Then how did you do it? Did you directly find He Xizhou to extract it?"
"No, no, that would be easy to scare off the enemy." Zhao Guozhi denied this statement and said:
"We thought about it at the time, but then we all put it together and decided to extract it secretly."
"Secret extraction?" Lu Weiwei was a little confused.
Zhao Guozhi smiled faintly and continued to explain: "Because at that time, a partner in the investigation team said that he was going to stay in He Xizhou and asked me if I wanted to join him?"
"I agreed without thinking much at the time, so we sat near his house and waited to obtain He Xizhou's DNA."
"So the next night, we disguised ourselves in civilian clothes and followed him to an ice rink."
"And now he's married and has kids, and he's in the rink with his kids."
"A few of us were very patient and waited for him to buy drinks, but he used a foam cup when drinking the drinks."
"As soon as he left the table, we plainclothes men immediately picked up the Styrofoam cup he left behind and sent it directly to the provincial crime laboratory."
"So that night, we got a record that matched his DNA."
"As a result, a search warrant was obtained to search his home, and while we were searching his home, we arrested him."
"And outside his home, we found a car covered with tarpaulin, and the color of the car was exactly orange, which matched the description of the airline flight attendant."
"Oh my God, I finally found the murderer." Lu Weiwei breathed a heavy sigh of relief when she heard this.
Zhao Guozhi nodded silently: "Yes, we have spent several years preparing for this day."
"And the car could no longer start at that time. It was covered with tarpaulin."
"What shocked us the most was that we found hundreds of women's underwear, bras, and other such things in his home, hundreds of items, all hidden under his mattress."
"We didn't know at the time, how did he hide this from his wife?"
