I'm a Super Cop

"Scorpions have a lot to offer?" Lu Weiwei looks at Zhao Guozhi suspiciously.

Maybe it's because of the short police time. In Lu Weiwei's impression, she has never heard of a character named "scorpion".

But Lao Wang is different. Lao Wang is an old comrade.

What's more, Zhao Guozhi, a senior policeman, must know more.

Zhao Guozhi coughed two times and said: "I should be impressed with this scorpion."

"When I was a little police officer, I met this guy named" scorpion "when I was working with Qin Bureau."

"Only at that time, Scorpion was just a young man of my age, and I was no longer a teenager."

"Zhao Ju, what is the origin of the scorpion you are talking about?" Gu Chen can see that Zhao Guozhi can go there in person.

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

Zhao Guozhi took yuan Shasha's tea and said, "to talk about this scorpion, I have to go back to the time when I was a policeman."

"At that time, there was 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."

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

"Jiangnan academy?" Hearing Zhao Guozhi's words, Gu Chen was puzzled and said, "I know that place, but it's a scenic spot. How can people live in it?"

"That's now." Although Gu Chen knew Jiangnan academy, he didn't know the situation before Jiangnan academy, so he quickly explained:

"what was the concept of scenic spot in our time? Jiangnan Academy was an ancient building in Jiangnan City at that time. "

"And it's close to the citizens' Park, so it's like living in a fairyland to be able to live there."

"The master 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 lived in the upper room of the Academy."

"So Jiangnan academy can be rented out?" Wang police officer if thoughtful, is also tut tut said strangely: "this is not thought about."

Lu Weiwei also nodded silently and continued to ask, "but what does this have to do with scorpions?"

"Don't worry, listen to me slowly." See Lu Weiwei eager to know the scorpion's situation, Zhao Guozhi did not immediately say, but to tell.

"I remember that was 20 years ago, when a murder happened in Jiangnan academy, and the person who was killed was Hu Haixia."

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

For this era, many police officers have not experienced it, let alone understood it.

Especially when Zhao Guozhi was just a new police officer.

Zhao Guozhi nodded silently and continued: "at that time, I remember that Jiangnan Academy had just been restored and was in the deep of the park. It was a beautiful Jiangnan courtyard."

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

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

"Her head was almost cut off, and there were many wounds in her chest, and these wounds were not fatal, just small stab wounds, such as traces of torture."

"So cruel?" Hearing that Zhao Guozhi said, Lu Weiwei suddenly frowned slightly. She felt that the murderer's means were too cruel.

Zhao Guozhi sipped a cup of tea and sighed: "when I was working with the Qin Bureau, I saw such a tragic body for the first time. I almost didn't vomit it out."

"And I remember clearly that we noticed at that time that Hu Haixia's wrist was tied with some kind of plastic telephone line."

"And on the headboard, and on the wall above it, there are still bloodstains."

"The murderer cruelly cut off one of her arteries, and the bed was soaked with blood, but beside her, there was the clothes she wore that night, which had not been turned over, and the magazine at the foot of the bed had not been moved."

After hearing Zhao Guozhi's speech at the scene and restoring the original scene of the crime, Gu Chen also put forward his own opinion according to the only clues:

"if so, 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, also agreed and said: "at that time, the results of our investigation were the same."

"We thought at that time that the murderer didn't take anything from the room, and Hu Haixia lived alone, so it was difficult to determine whether she had lost anything.""But her purse is lying on the dining table outside, and her keys are still there."

After a pause, Zhao Guozhi added: "we divided the work of the case investigation at that time."

"Our current Qin Bureau was the person in charge of the whole case at that time. I was just his deputy. I was responsible for recording the scene, recording the scene in writing, describing the location of the evidence, and collecting the evidence."

"And I remember that I was assigned to draw a scale map of the whole house."

"Then, the peer who is specially responsible for the inquiry will carry out the work of questioning, visiting and verifying the license plate of the relevant personnel."

"Because the conditions of Jiangnan police station were limited at that time, Qin Bureau called the provincial crime laboratory, and then immediately withdrew from the house, so as not to destroy any evidence."

"After that, I worked with the people from the Crime Laboratory of the provincial department, and what I did was the same as when I was preparing the written records of the scene, mainly describing all the circumstances of the scene."

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

"Because there are some bloodstains that haven't been washed off, and these bloodstains are very light, because it's obvious that the killer tried to wash them off, but it didn't succeed."

"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 tap."

"Of course, it's an incomplete mark, but we don't want to take fingerprints at the scene, we want to take the tap back to the crime lab."

"What about coming back? Have the fingerprints been extracted? " Gu Chen asked.

Zhao Guozhi nodded silently: "yes, later we got a fingerprint from the tap."

"So far, everything has been going well, so we all left the scene."

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

"In addition to the fact that the murderer was not found at that time, we all felt the pressure during that time."

"So it is." Police officer Wang understood Zhao Guozhi's difficulties and echoed: "the lethality of newspapers in those days was also very huge."

"The murder cases that can be reported should have a high degree of attention. I also remember hearing the elders talk about it in those years, but I don't know what happened later."

"This matter is very sensitive. The deceased was an educator or a local celebrity, so there is a lot of pressure to investigate." Zhao Guozhi said.

Lu Weiwei then asked, "what was your investigation direction at that time? Start with acquaintances? "

"Yes, starting with acquaintances." Zhao Guozhi did not deny Lu Weiwei's view, but also agreed with her: "our investigators at that time focused on an acquaintance of Hu Haixia."

"Because at that time, that is, before the crime, he once 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 the progress was very slow."

"At that time, many police officers thought that Hu Haixia's acquaintance was the murderer."

"But unfortunately, the fingerprint we found at the scene didn't 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 at that time, we all thought that we could rely on this database to connect with the national database, but in fact, it was not the case."

"Therefore, for many years, this fingerprint has been stored in the system of the provincial department, waiting for the matching fingerprint to appear, but its search scope is limited to the province."

"What a pity." Hearing Zhao Guozhi's speech, Gu Chen also shook his head repeatedly.

It is true that the database was not perfect at that time.

But Gu Chen also wanted to know what was going on, so he continued to ask Zhao Guozhi.

"Zhao Ju, what happened later?"

"Later?" Zhao Guozhi's expression stagnated for a while, and then he said: "later, because there was no matching clue, many years passed, and this became an unsolved case."

"Is there no clue?" Lu Weiwei asked, feeling that this case is really difficult.

After all, every era has its own brand.

Just like on the street in those days, there were very few surveillance cameras.

All kinds of criminal investigation technology is still very backward, so if you want to solve a case quickly, and there is no clue to support it, the case investigation will be very passive.

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

"But later, every once in a while, there will be some clues about this case, and then we will go to inquire about the relevant information.""Later, my partner, the Qin Bureau, who is responsible for the investigation of the whole case, was transferred to the Beijing Institute of administration to study. A lot of work in this case was brought to a standstill."

"I was the only one who was still investigating the case among the people who initially participated in the investigation, but all the clues didn't lead to any results."

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

"Because I'm very familiar with this kind of case, I went back and did what 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 who attended a party before she was killed."

"Some of these people have died and some have moved to other provinces."

"But now DNA technology is very advanced because we always thought that the DNA samples we found at the crime scene were not good enough."

"Because at that time, after the murder, the killer connected the electric blanket on the bed of the victim Hu Haixia."

"At that time, Hu Haixia's body was lying on that bed. At that time, everyone thought that the DNA in Jingye found at the scene had no use value, and it might have been damaged by the electric blanket."

After a pause, Zhao Guozhi said: "but later we found that the actual situation is not so."

"We took this sample back and sent it back to the laboratory, and the provincial laboratory sent it back to the merged DNA database, which is the national DNA database."

"At that time, we were very excited because we found the matching DNA, which came from Haidong City, where Haidong airport is located."

Hearing Zhao Guozhi's words, Gu Chen frowned and asked: "Zhao Bureau, since we have found the matching DNA, does it mean that similar cases have happened 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, Jiping is the same as Hu Haixia."

"But after our investigation, we found that because the stewardess was younger, the killer was not able to subdue her as quickly as Hu Haixia."

"The stewardess resisted, so the knife left a defensive wound on her right hand, but her head was almost cut off."

"Eh!" Hearing Zhao Guozhi's words, Lu Weiwei frowned: "this is too cruel. How abnormal is the murderer?"

"It's all murderers. How normal can you expect murderers to be?" Police officer Wang also joked, then asked: "by the way, Zhao Bureau, what's the matter with this case?"

Zhao Guozhi tried hard to recall, and then said: "this case happened in the hotel next to the airport, and the victim just completed the flight mission that night."

"According to the investigation at that time, she was a temporary substitute for another stewardess to fly that flight, but no one knew that she was staying in the hotel where the accident happened."

"But she didn't show up on her flight the next day. It was only because someone checked her room and found her body there that the incident was broken."

"But in the course of our investigation, we found that the night before the accident, the stewardess had a male flight attendant who was staying in the hotel and saw it from his room window."

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

"But after the case, Hu Haixia's son saw the relevant report in the newspaper, so he made a decisive contact with the police station in Haidong city."

"He told Haidong police at that time that the case looked very similar to his mother's murder in Jiangnan City a few years ago."

"But he didn't make it very clear that he contacted the police officer in Haidong city by telephone. At that time, the police officer was not in charge of the case and was in the off-duty time, so he was negligent. In the end, the matter was not settled."

"That's very kind of you." Gu Chen shook his head and sighed: "if they compare the scene photos of the two cases, they will know that the murderer may be the same person."

"Yes." Lu Weiwei also agreed: "it's obvious that the modus operandi are very similar."

"No way." Zhao Guozhi shook his head and told the truth: "there are always some people who are not so interested in their work. They only care about their own affairs, so they miss this important clue."

"But later 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 swabs from all the people we have interrogated, including the victim's good friends, enemies, and even the women concerned. "

"Because the members of the ad hoc group set up at that time came from the Crime Laboratory of the provincial department, our samples were given priority."

"Within a few days, we got the information we needed."

"Although these two cases have become outstanding cases, when we found the matching records in the database, the investigators of the two cases sat together."

"I checked the fingerprint record again at the crime lab and realized that it was only entered into the automatic fingerprint identification system of the provincial department and never 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 matches 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 repeatedly entered other people's rooms and stolen women's underwear and Wen chest."

"Not only that, he was arrested in other places. Later, he returned to Jiangnan City and began to work in his father's sprinkler system company."

"This company has also provided services for Jiangnan Academy."

"Because four days before the murder, the man named he Xizhou and several other people from the company came to Jiangnan Academy."

"Because it was getting colder and colder, they went to shut down the sprinkler system there to prevent it from freezing."

"The control facilities of this system are located on the ground floor of Hu Haixia's room."

Seeing people staring at him, Zhao Guozhi also told the truth: "at that time, we were very sure that he should be the murderer."

"So there are his fingerprints at the scene, he may have a chance 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."

"It's often said that they saw Hu Haixia lying there naked and fruity, and she didn't shy away from visitors outside."

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

"And we really believe that he Xizhou is the murderer, but we have to compare his DNA with the DNA found at the scene."

Gu Chen nodded silently and asked Zhao Guozhi, "how did you do that? Can we get hexizhou directly? "

"No, no, that's easy." Zhao Guozhi denied this, and said: "we thought about it at that time, but later we decided to extract it secretly."

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

Zhao Guozhi continued to explain with a faint smile: "because at that time, a partner of the investigation team said that he was going to stay in hexizhou and asked me if I would like to join him?"

"At that time, I didn't think much about it, so I agreed to come down, so we sat near his house, waiting to get the DNA of Hexi island."

"So the next night, we dressed up as plain clothes and followed him to an ice rink."

"And now that he's married and has kids, he's on the rink with his kids."

"a few of us are very patient, waiting for him to buy drinks, and when he drinks drinks, he uses a foam cup."

"and as soon as he left the table, our plainclothes, he immediately picked up the foam cups left by him and sent them directly to the crime lab of the provincial hall."

"So that night, we got a match with his DNA."

"So we got a warrant to search his house, and we arrested him while we searched his house."

"And outside his home, he found a car covered with tarpaulin, and the color of the car is orange, which is consistent with the description of the airline flight attendant."

"Oh, my God, we finally found the killer." Lu Weiwei felt a heavy sigh of relief when she heard the speech.

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

"And at that time, the car could no longer start. It was covered with tarpaulin."

"What shocked us most was that we found hundreds of women's underwear, Wen's breasts, and other things in his home. Hundreds of them were hidden under his mattress."

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