At the beginning of the morning, a beautiful day began, and Lin Tingting, a girl full of youthful vitality, began to run and exercise in the morning.
She ran downstairs to a village house, and suddenly a flower pot "banged" next to her, almost hitting a little girl passing by.
Lin Tingting was startled, she looked up and found a blood-stained hand hanging from the outside of the railing, and a few drops of blood dripping down.
Lin Tingting hurriedly called the police, and soon, the police, forensics, and forensic doctors all rushed to the village house.
The village house where the crime occurred was the family of Tan De, a jewelry vendor, and all four members of his family fell in pools of blood.
The male host Tan De, the hostess Mrs. Tan, and their daughter Tan Liling were all stabbed in the chest and have died. On the balcony is their son Tan Weisheng, Tan Weisheng was stabbed in the back and lost too much blood, but he still has a breath.
In fact, downstairs, senior chemist Gao Yanbo found uncoagulated blood dripping down, and he had already judged that there were still people who were not dead.
Tam was sent for first aid, and forensic evidence and police conducted a search for evidence.
The forensic team found a diamond that had fallen to the ground and a torn velvet bag at Tander's home. The police deduced that the killer had killed the man in order to snatch the diamond.
The toilet seat, window side, and water pipes on the exterior wall were covered with shoe prints, and Inspector Liang Xiaorou suspected that the murderer had climbed in from the outside to grab diamonds and commit murder.
Through the investigation of the close social relationship with the Tan family, the police's suspicious eyes fell on Tan Liling's boyfriend Chen Wendi.
Chen Wendi is a wage earner who works in a garage, and he is poor and short-sighted, and Tan De has always disagreed with his daughter dating him.
But Tan Liling was pregnant, and Chen Wendi wanted to secretly take Tan Liling away, but she didn't expect to be discovered by Tan De. In the chaotic quarrel, Tan De hit Chen Wendi with the wrench brought by Chen Wendi, and Tan Liling was also pushed to the corner of the table by her father, hit her stomach and miscarried.
Killing people with a grudge and snatching diamonds, the wrench of one of the murder weapons belongs to Chen Wendi, according to these facts and evidence, it seems logical that Chen Wendi is the murderer.
But as the investigation deepened, the police found out that on the night of the accident at Tan De's house, Chen Wendi and his accomplices went to steal the car. Chen Wendi's theft was handled separately, but it was also his alibi.
At this time, Tan Weisheng, who was seriously injured and unconscious, woke up, he was the only survivor, and Liang Xiaorou immediately rushed to the hospital with his subordinates.
Liang Xiaorou asked about the incident, Tan Weisheng said that he was busy with the company's affairs, and he didn't get home until about four or five o'clock in the morning, and as soon as he entered the door, he was attacked from behind, hit with a wrench, and then stabbed in the back with a knife. He did not see what the murderer looked like because he had his back to him.
Tan Weisheng could not provide useful clues, and the police could only start from the physical evidence. Forensic Gao Yanbo soon discovered an irrationality.
He discovers that the shoe prints left by the killer on the water pipes outside the wall are not right. The shoe print is heavy in the middle and light on all sides, that is, the murderer is "small feet wearing big shoes".
Also, based on the size of the shoe print, the inferred height should be a tall man, but the distance left on the wall shows that he is a short man. This further proves that the murderer was "small feet with big shoes". The murderer had small feet and deliberately wore big shoes, leaving footprints to confuse the police.
The forensic officer found the bloodstained shoes discarded by the killer and confirmed that the shoes belonged to Hide. Sure enough, the murderer deliberately wore Tan De's shoes to confuse the police.
Liang Xiaorou, Gu Zechen, and Gao Yanbo re-enacted the case at the scene of the crime, and soon discovered the suspiciousness of Tan Weisheng's confession.
A poster of supermodel KiKi was posted on the balcony of Tam Weisheng's house, and on the day of the crime, a crazy fan took a picture of the poster. In the photo, you can see someone at Hide's house, and the time is half past six. And Tan Weisheng said that he went home at four or five o'clock, and then was attacked. It stands to reason that the murderer should have fled and should not have remained at the scene. The timing is not right.
According to the real size of the footprints, the inferred height of the murderer and Tan Weisheng's height coincide. The height of the murderer captured in the photo is also consistent with Tan Weisheng's height.
Gao Yanbo found traces of human blood on a knife in the kitchen, and also found the fibers of a towel on a cabinet.
They suspected that Tan Weisheng was the murderer of their family, and deduced the history of Tan Weisheng's crime.
As his injuries improved, the police took him home.
The home was still stained with blood, and Tan Weisheng, who was in a wheelchair, looked very uncomfortable. But in the face of Liang Xiaorou's questioning, he still tried all kinds of quibbles and refused to admit that he was the murderer of his relatives.
You can only let the facts speak.
Gao Yanbo found that the clothes Tan Weisheng was wearing at the time of the crime had some moss on the sleeves, called sheep's tooth moss. And this moss is the moss that grows in indoor fish tanks.
Gao Yanbo walked to the fish tank in the living room, rolled up his sleeves, and put his hand into the sand of the fish tank. After fumbling in the sand, he found a bag of things, which were the missing diamonds.
In front of the evidence, Tan Weisheng could no longer quibble, and finally told the facts of his crime.
Tan Weisheng opened his own IT company, but the company was sluggish and often lost money.
Tan De has always disapproved of his son's career, believing that he will only lose money. Due to a disagreement in philosophy, the two fathers and sons often quarreled.
This time, Tan Weisheng's company fell into an economic crisis again and urgently needed a cash turnover. He knew that his father had a batch of diamonds on hand and wanted to borrow them for emergency relief. But thinking of his father's attitude towards him on weekdays, he knew that his father would definitely not lend it to him.
If you can't borrow it openly, you will steal it secretly. At night, while his family was asleep, Tan Weisheng stole the diamonds in the safe.
But Tan De was awakened by a strange noise and found that Tan Weisheng had stolen diamonds.
Tan De originally had prejudices against his son and felt that he was not a talent. Now that he actually stole something, he was even more angry and trembling.
The grumpy Tander didn't listen to his son's explanation at all, and picked up the phone to call the police.
Tan Weisheng knelt down and begged hard, but he couldn't stop his father. Frightened, he picked up the fruit knife on the table and stabbed his father in the chest.
The mother and sister who were awakened by the sound of the quarrel came out to persuade them to fight, not only did not stop the quarrel, but also witnessed the tragedy of Tan Weisheng's murder of his father.
Tan Weisheng had lost his mind, and he didn't stop doing it, and stabbed his mother in the chest with a knife. Ignoring his sister's pleas, he raised his knife and stabbed his sister again.
The whole family fell in a pool of blood. Looking at the bloody scene, Tan Weisheng regained his senses. After stabilizing his mind, he began to think about how to get rid of his sin.
His family members are dead, and he has to be injured to avoid suspicion. It is better to have the wound in the back and be able to reasonably explain that you have been attacked and cannot see the face of the murderer.
Tam first collected the diamonds and hid them in the sand of the fish tank. It was when he was hiding the diamond that his sleeve was rubbed with moss, but this insignificant detail was discovered by Gao Yanbo.
Then, he put on his father's leather shoes and deliberately left shoe prints on the toilet lid of the toilet, by the window, and on the water pipe on the exterior wall, creating the illusion that someone had climbed in from the outside to grab the diamond and commit murder.
Back in the house, Tam wrapped the handle of the knife in a towel, fixed it between two sets of cabinets, and then hit the tip of the knife with his back, creating the illusion that he was stabbed in the back by the gangsters.
Tan Weisheng wanted to regain some strength and lightly stab himself, but he and his father lost a diamond in the fight, and he didn't notice. When he slammed into the tip of the knife, he stepped on the diamond, his foot slipped, and his back hit the fruit knife hard, and he was extremely badly injured.
He pulled the knife out of the cabinet with all his might, struggled to the kitchen to rinse off the bloodstains, and then while he still had a trace of consciousness, he climbed to the balcony and pushed the flower pot downstairs, hoping that someone would find him and rescue him in time.
Tam Weisheng is cruel, cold-blooded, and inhumane. After killing his relatives, he calmly and carefully arranged the scene, without regret or sadness, only thinking about how he could get rid of his crimes.
Tan Weisheng thought he was so smart that he could play with the police in the palm of his hand, but he didn't expect that he couldn't escape the forensic eyes at all.
He killed three of his closest relatives, faced police questioning, and repeatedly complained about his father's cold-bloodedness. But how innocent are the defenseless mother and sister, and how can they not be cold-blooded and ruthless?
What awaits him is the severe punishment of the law. The home is gone, the career is gone, and the rest of my life will be spent in prison.
On the table is a family portrait of the Tan family. A family of four snuggled together, beaming with happy smiles. But this happiness was destroyed by Tan Weisheng himself.
