I am a super cop

Chapter 1262 The murder of Jiangnan Academy

"What is the background of the scorpion?" Lu Weiwei looked at Zhao Guozhi suspiciously.

It may be because of the short police time, in Lu Weiwei's impression, 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 about it.

Zhao Guozhi coughed twice, and said involuntarily, "I should have an impression of this scorpion."

"At the beginning, when I was a young police officer, I met this guy named 'Xiong' when I worked with Bureau Qin."

"It's just that the scorpion at that time was just a young man of my age, and now I'm no longer a teenager."

"Zhao Ju, what is the relationship between the 'scorpion' you mentioned?" Gu Chen could tell that Zhao Guozhi could go there himself.

It can be seen that this so-called "scorpion" character has special significance to Zhao Guozhi.

Zhao Guozhi took the tea that Yuan Shasha had made, and then said eloquently: "If we want to talk about this scorpion, we have to go back in time to when I first joined the police force."

"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 Engineering University."

"And she is also famous for organizing folk culture festivals in Jiangnan City every summer, and she is also well-known in the academic circles. She lived in the ancient Jiangnan Academy at that time."

"Jiangnan Academy?" Hearing Zhao Guozhi's remarks, Gu Chen was a little puzzled and said, "I know that place, but it's a scenic spot, why would people live there?"

"That's now." Seeing that although Gu Chen knew Jiangnan Academy, he didn't know the situation before Jiangnan Academy, so he quickly explained:
"In our time, how could there be any concept of a scenic spot? Jiangnan Academy, in the ancient Jiangnan City at that time, it was an ancient building."

"Besides, it is close to the Civic Park, so being able to live there can be said to be living a fairy-like life."

"And 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 was renting in the upper room of this academy."

"It turns out that Jiangnan Academy can be rented out?" Police Officer Wang said thoughtfully, "I never thought about it."

Lu Weiwei also nodded silently, and continued to ask: "But what does this have to do with the scorpion?"

"Don't worry, listen to me slowly." Seeing that Lu Weiwei was eager to know the situation of the scorpion, Zhao Guozhi didn't say it right away, but eloquently.

"I remember that it was 20 years ago. At that time, there was a murder case in Jiangnan Academy, and the person who was killed was Hu Haixia."

"Hu Haixia was killed?" Hearing Zhao Guozhi's words, many old and new police officers looked at each other in blank dismay.

For this era, many police officers have never experienced it, let alone understand it.

Especially when Zhao Guozhi was just a new police officer.

Zhao Guozhi nodded silently, and continued: "At that time, I remembered that Jiangnan Academy had just been restored, and it was located in the depths of the park. It was a beautiful Jiangnan courtyard."

"The reason why Hu Haixia rented the house here is probably because she thinks that being able to tell others that she lives in Jiangnan Academy is a very glorious thing."

"And when we investigated this case, we found Hu Haixia lying naked on the bed."

"And her head was almost cut off, and there were many wounds on her chest, and these wounds were not fatal injuries, just some small stab wounds, like marks left by torture."

"So cruel?" Hearing Zhao Guozhi's words, Lu Weiwei frowned, feeling that the murderer's methods were too cruel.

Zhao Guozhi took a sip of tea, sighed faintly and said, "I worked with Bureau Qin back then, and it was the first time I saw such a tragic corpse, and it almost made me spit it out."

"And I still clearly remember that we also noticed that Hu Haixia's wrist was tied with some kind of plastic telephone wire."

"And on the headboard of the bed, and on the wall above it, there were blood stains."

"The murderer brutally severed one of her arteries, and the bed was soaked in blood, but next to her, the clothes she wore that night were left untouched, and the magazines at the foot of the bed were untouched."

Hearing Zhao Guozhi's on-the-spot remarks and restoring the original crime scene, Gu Chen also put forward his own opinion based on the only clues:

"If this is the case, does it mean that Hu Haixia didn't struggle at that time, but the murderer completely controlled her and tied her up, but Hu Haixia couldn't resist at all?"

"That's right." Zhao Guozhi nodded slightly, and agreed, "The result of our investigation was also the same."

"We believed at the time that the murderer hadn't taken 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 outside on the dining table and her keys were still there."

After a pause, Zhao Guozhi said again: "We divided up the investigation of the case at that time."

"Our current Bureau Qin was in charge of the entire case back then. I was only his deputy, responsible for on-site records, making written records of the scene, describing the location of each evidence, and collecting evidence."

"And I remember at the time, I was assigned to draw a scale drawing for the entire house."

"Then the counterparts who are responsible for the interrogation will carry out the work of interrogating, visiting and verifying the license plate of the relevant personnel."

"Because the conditions of the Jiangnan City Police Department were limited at that time, the Qin Bureau called the Provincial Department's crime detection laboratory, and then immediately evacuated the house to avoid destroying any evidence."

"After that, I worked with people from the Ministry's crime laboratory, and the work I did was the same as I do now when I prepare the written records of the scene, mainly describing all the circumstances at the scene."

"And when we searched the house, we found the place where the murderer washed the blood after the murder, that is, a ceramic washbasin in the bathroom next to the bedroom of the victim Hu Haixia."

"Because there were some unwashed bloodstains in there, which were very faint, because it was clear that the killer had tried to wash them off, but hadn't been able to."

"And these clues were also recorded by me one by one, and we also found that there may be a fingerprint on the cold water faucet."

"Of course it's an incomplete blot, but we don't want to take fingerprints on the spot and take the tap back to the crime lab."

"Then come back? Has the fingerprint been taken?" Gu Chen asked.

Zhao Guozhi nodded silently: "Yes, we did extract a fingerprint on this faucet later."

"Up to that point, the investigation had been going well and we all left the scene."

"But then everyone in our department was harassed by the media because of the "Jiangnan Academy Murder" headline in the newspaper."

"In addition, the murderer was not found for a long time, so at that time, each of us felt a lot of pressure."

"That's right." Officer Wang understood Zhao Guozhi's difficulties, and echoed, "The lethality of newspapers back then was also very huge."

"A murder case that can be reported should have a high degree of attention. I also remember that I heard it from the elders, but I don't know what happened afterwards."

"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: "Then what was the direction of your investigation at that time? Did you start with acquaintances?"

"That's right, start with acquaintances." Zhao Guozhi did not deny Lu Weiwei's opinion, but also agreed with it:
"Our investigators at the time focused on an acquaintance of Hu Haixia."

"Because at that time, that is, before the incident, he had 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 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 that 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 and connect with the national database, but in fact it was not the case."

"So, for many years, this fingerprint has been stored in the Ministry's system, waiting for a matching fingerprint to appear, but the scope of its search is limited to the province."

"It's a pity." Hearing Zhao Guozhi's words, Gu Chen shook his head again and again.

It is true that the database was not perfect back then.

But Gu Chen also wanted to know the progress behind, so he continued to question Zhao Guozhi.

"Zhao Ju, what happened next?"

"Later?" Zhao Guozhi's expression froze for a moment, and then he said again: "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 really difficult.

After all, every era has its imprint.

Just like on the streets back then, there were very few surveillance cameras.

The technical level of various criminal investigations is still very backward. Therefore, if you want to solve the case quickly and have no clues to support it, the investigation of the case will appear very passive.

Zhao Guozhi shook his head and sighed: "I was also very young at that time, and I really wanted to solve the case quickly. At that time, I could also feel the pressure from Bureau Qin."

"But then, every once in a while, there will be some clues about this case, and then we will check the relevant information."

"Later, my partner, Bureau Qin, who was in charge of the investigation of the entire case, was transferred to study at the Beijing School of Administration. A lot of work on this case came to a standstill."

"I'm the only police officer who is still investigating this case among those originally involved in the investigation, but none of the leads have led to anything."

"But a few years later, I remember it was a spring, the case investigation team of the Municipal Bureau called and asked me to investigate this case with them again."

"Because I'm very familiar with this kind of case, I went back and did the work that they had done."

"That is to visit the friends of the victim Hu Haixia, the people who were with her on the night of the murder, and the people at a party she attended before she was killed."

"Some of these people have passed away, and some have moved to other provinces."

"But the DNA technology is so advanced now because we used to think that the DNA samples we found at crime scenes weren't good enough."

"Because at that time, after the murder, the murderer switched 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 that the DNA in the semen found at the scene was useless, and it was probably destroyed by the electric blanket."

After a pause, Zhao Guozhi continued, "But we found out later that this is not the case."

"We took the sample back and sent it back to the lab, and the ministry's lab, at that time, sent it to the combined DNA database, which is the national DNA database."

"At that time, we were extremely excited because we found a matching DNA, and this DNA came from Haidong City, where Haidong Airport is located."

Hearing what Zhao Guozhi said, Gu Chen frowned, and hurriedly asked: "Ju Zhao, since we found a matching DNA, does it mean that a similar case happened in Haidong City?"

"You're right." Zhao Guozhi flicked his fingers, and said in a positive tone: "At that time in Haidong City, a flight attendant was killed."

"The way she was killed was almost the same as that of Hu Haixia."

"However, after our investigation, we found that because the flight attendant was relatively young, the murderer was not able to subdue her as quickly as Hu Haixia."

"The flight attendant resisted, so in her right hand, the knife left a defensive wound, but her head was almost severed as well."

"Huh!" Hearing Zhao Guozhi's words, Lu Weiwei frowned slightly: "This is too cruel, how perverted is this murderer?"

"They're all murderers, how normal can you expect the murderer to be?" Police Officer Wang also joked, and then asked: "By the way, Director Zhao, what's going on with this case?"

Zhao Guozhi tried his best to think about it, and then said: "This case happened in a hotel next to the airport, and the victim had just completed his air 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 that flight, but no one knew that she was staying in the hotel where the accident occurred."

"But she didn't show up on her flight the next day, and it was finally revealed because someone checked the room where she was staying and found her body there."

"However, during our investigation, we found that the night before the accident, a male flight attendant who lived in the hotel saw the flight attendant from the window of his room."

"In the parking lot, there was a man who was walking towards his orange car with an airline suitcase, and he thought that man was also a flight attendant."

"But after this case happened, Hu Haixia's son read the relevant reports in the newspaper, so he decisively contacted the police station in Haidong City."

"He told the police in Haidong City that this case looked very similar to the murder case of his mother that happened in Jiangnan City a few years ago."

"But because he contacted the policeman in Haidong City on the phone, he didn't make it clear, and the policeman was not in charge of the case at the time, and he was off duty, so he was negligent, and in the end this matter will not be resolved. It's over."

"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. "

"That's right." 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 don't care about their work. They only care about their own affairs, so they missed this important clue."

"But then they didn't get in touch with Hu Haixia's son, and we finally found a matching record in the database."

"We knew then that it 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 have interviewed, including the victim's good friends, enemies, and even the women involved. "

"Because the task force established at that time had members from the Ministry's crime laboratory, our samples were given priority."

"Then within a few days, we had the information we needed."

"While both cases were unsolved, when we found matching records in the database, investigators from both cases sat together."

"I looked at the fingerprint record again at the crime lab and realized it had only been entered into the Ministry's Automated Fingerprint Identification System and had never been sent to the national database."

"So I immediately submitted this fingerprint to the head of the laboratory, and then we found a matching record in the fingerprint database."

"The fingerprint taken 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, in Jiangbei City, has entered other people's rooms many times and stole women's underwear and breasts."

"Not only that, but he was also arrested in other places, and then he returned to Jiangnan City and started working in the sprinkler system company where his father worked."

"And this company also happened to have provided services for 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 at the time, they went to turn off the sprinkler system there to prevent it from freezing."

"And the control facility of this system is located underground in Hu Haixia's room."

Seeing everyone staring at him intently, Zhao Guozhi also said truthfully: "At that time we were very sure that he should be the murderer."

"So there are his fingerprints on the scene, he has the chance to enter the scene, and he may have seen 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 that she doesn't shy away from tourists outside."

Seeing that everyone was ashamed of Hu Haixia's "openness", Zhao Guozhi said again: "Let me tell you this. From my understanding, this Hu Haixia is not afraid of her body being exposed."

"And we are really sure 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 just call He Xizhou to extract it?"

"No, no, that's easy to scare the snake." Zhao Guozhi denied this statement, and said:

"We also thought about it at the time, but then everyone decided to extract it secretly."

"Secret extraction?" Lu Weiwei didn't quite understand.

Zhao Guozhi smiled lightly, and continued to explain: "Because at that time, a partner of the investigation team said that he was going to stay in He Xizhou, and asked if I wanted to come together?"

"I didn't think much about it at the time, so I agreed, so we sat near his house and waited to get He Xizhou's DNA."

"So the next night, we disguised ourselves as plainclothes and followed him to a skating rink."

"And he's married now and has a kid, and he's in the rink with his kid."

"A few of us were very patient and waited for him to buy drinks, and when he drank the drinks, he used a foam cup."

"As soon as he left the table, we plainclothes immediately picked up the Styrofoam cup he had left behind and sent it directly to the Ministry's 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 we arrested him as we searched his home."

"And outside his house, a car covered with tarpaulin was found, and the color of the body was orange-yellow, which matched the description of the airline flight attendant."

"Oh my god, we finally found the murderer." Lu Weiwei also heaved a sigh of relief when she heard that.

Zhao Guozhi nodded silently: "Yes, we have spent several years for this day."

"And the car couldn't start at that time, and it was covered with a tarpaulin."

"And what shocked us the most was that we found hundreds of women's panties, bras, and that sort of thing in his home, hundreds of them, all hidden under his mattress."

"We didn't know at the time, how did he hide it from his wife?"
