The woman was brutally strangled to death on the bed in the house, the scene was messy, and the woman's clothes were thrown everywhere. After receiving the report, the police quickly arrived at the scene.

During the investigation of the scene, the police found that the woman had traces of being raped, and in addition to this, they found semi-suspicious footprints in the room. Curiously, there were no traces of the deceased's home being turned over, nor did any important items have been lost, which has made the police suspicious.
The target of this murderer, if it is only this woman, then he must be very attached to this woman. Coupled with the fact that the door lock in the deceased's home was not broken, if it was not the woman who took the initiative to open the door for the murderer, it was the other party who entered the house with the key, so the murderer must have been an acquaintance.
After having the initial clues, the police rushed to the place where the woman worked. The victim's name was Huang Bei, a doctor in the laboratory department of the local hospital, and she was born very beautiful, even if she had a high popularity in the hospital. According to the response of the nurses in the hospital, because Huang Bei was married, there were very few male doctors in the hospital who were close to her, except for one named Dr. Li Xinguang.
Li Xinguang's contacts with Huang Bei on weekdays are very close, and even there are some ambiguous meanings in the shadows, and colleagues in the hospital also look at this matter in their eyes, and from time to time they will talk about the gossip of the two people. After learning about this situation, the police were preparing to summon Li Xinguang to come and ask questions, but no one thought that at this juncture, the police on the other end came with news, and Li Xinguang ran away.
After the police received the news, they quickly dispatched police forces to track down Li Xinguang's whereabouts. The police speculated that Li Xinguang was likely to abscond in fear of crime, so most of them would flee to other places through the station, so they arranged manpower at each station separately, and indeed arrested Li Xinguang, who was ready to escape by car.
However, when Li Xinguang was taken back to the police station, he was confronted by the police, but he firmly denied the fact that he killed Huang Bei. According to him, the relationship between himself and Huang Pei is just an ordinary friendship. Huang Bei's personality is too outstanding, it is difficult for ordinary people to get along with her, it just so happens that Li Xinguang is very suitable for her temperament, and the two can only say a few words. As for the reason why I want to run, it is only because I am afraid that the people in the hospital will gossip, and I plan to wait until the matter is cleared up before returning to work.
Since there was no evidence of directness, the police simply collected some information from him and released him.
At this time, the husband of the deceased, Guo Jingtao, received the news of his wife's murder and immediately rushed back to the city. Because of his work, he happened to be on a business trip yesterday, but he didn't expect that he had only left for one night, and his wife had been killed in a house.
When the police asked him what he thought of Li Xinguang, Guo Jingtao did not react much, but said that there was not much contact between him and Li Xinguang, but he believed that Li Xinguang was a person of integrity and would probably not do such a thing.
At the same time, the police investigating in Huang Bei's home have made new discoveries. In the bookcase, they found the account book left by Huang Bei, and in this account book, the name that appeared most often was Li Xinguang, and there was a large amount of capital exchanges between the two, which was obviously not a normal phenomenon.
The police immediately applied for a search warrant and immediately conducted a search of Li Xinguang's home. Soon, they found a box full of cash in Li Xinguang's bedroom. This money was exactly what he got from Huang Bei. As for the matter of money, Li Xinguang did not mention it in the slightest before, which undoubtedly aggravated the suspicion on him again. Could it be that he wanted to put Huang Bei out of his mouth and then take the money she had put in his own place for himself?
Because Li Xinguang was suspected of committing a major crime, the police took him back to the police station. Unexpectedly, after Li Xinguang's wife learned of this incident, she immediately rushed to the police station and arrogantly accused the police handling the case that her husband was wronged. It turned out that he had just gone to ask the neighbors of Huang Bei's house, and learned from the neighbors that on the night of the crime, he had seen a man come to call Huang Bei's door, although the neighbors did not see who it was, but it was definitely not Li Xinguang.
After getting this clue, the police once again found Huang Bei's husband and asked him if there were any suspicious people besides Li Xinguang. Speaking of suspicious people, Guo Jingtao really remembered one. It was a man named Ah Bin, who had a relationship with Huang Bei for a while during his school days, and after he was unilaterally dumped by Huang Bei, he still refused to let go, so he made a vow not to marry for life, and even ran to the scene to make a big fuss on Huang Bei's wedding day.
According to Guo Jingtao, the police quickly found this Ah Bin. For Huang Bei's death, he was very sad, although he hated Huang Bei for ruining his life, but he also loved him deeply, when Huang Bei was alive, he still had a hope, but now, the hope is gone, he also has the idea of finding short-sightedness.
In just a few words, the police can basically rule out Ah Bin's suspicions, and the subsequent footprint identification also confirms the police's speculation. The half-cut footprints left at the scene do not belong to Ah Bin or Li Xinguang. Today, the only two suspects have been ruled out, and the investigation of the case has also reached an impasse.
However, just when the police had no clue, the anti-corruption bureau people suddenly found the bureau and learned about Guo Jingtao's person. It turned out that Guo Jingtao, who was deputy director of the Municipal Science and Technology Commission, had just been anonymously reported some time ago and was suspected of a major corruption and bribery case.
This incident made the Sang team in charge of this case realize that things did not seem to be so simple. Due to the recent high-intensity investigation work, the Sang team has somewhat alienated the wife of the family, just when the Sang team returned home, his wife was not accustomed to his behavior of not being home, simply moved out of his boss to compare with him, and even threatened to be a third party of the family, which made the Sang team blush and have a thick neck. If he hadn't wore a police badge on his head, he really wanted to kill her like this.
As soon as this thought came up, the Sang team suddenly realized that Guo Jingtao would not be unaware of the little incident between Huang Bei and Li Xinguang, but when the police asked him about Li Xinguang, he acted very calmly, which was obviously very abnormal.
Subsequently, the police followed the clues and rushed to the place where Guo Jingtao was on a business trip to investigate, and found that on the day huang Bei was killed, there was also a case of burglary and rape here. As the police further investigated, they found that the victim's husband was a bathing center owner named Li Yan. Coincidentally, between him and Guo Jingtao, it turned out that he was still an old acquaintance. The most important point is that on the day of the crime, Li Yan also went to Guo Jingtao's city for business.
The truth is already very obvious, Guo Jingtao and Li Yan, and their wives do not have a harmonious relationship, the two are old acquaintances, often together to complain about the family. When both parties learned that the other's wife had a tendency to cheat, they colluded, raped and killed the other's wife, and used the reason of the business trip to prove that the other party had no motive for the crime.
In the end, after a meticulous forensic investigation, Guo Jingtao and Li Yan could no longer argue, and in the face of the evidence in the hands of the police, they were left with only one choice. And what awaits them in the back will be the severe punishment of the law.
