Six members of a family were killed in this case.
Deceased: male, 44 years old, Zhang wangguo, contractor.
Dead: female, 42 years old, Lin Xiufang, a housewife, helped to cook at the construction site.
Deceased: male, Zhang Yang, 20 years old, dropped out of school, was unemployed and had a father son relationship with Zhang wangguo.
The deceased: female, Zhang Hong, 22 years old, graduated from high school and was at home. Later, she checked in a supermarket and had a father daughter relationship with Zhang wangguo.
The dead, male, 65 years old, Zhang Youlin, is Zhang wangguo's father, a farmer.
The deceased, female, 63 years old, Miao Hua, is Zhang wangguo's mother, a farmer.
All the dead were killed with one knife. There were signs of fighting at the scene. Only Zhang Hong died in his own bed, as if he had been stabbed in the heart while sleeping, but his head was missing. There were more than 30 knives on Zhang wangguo's body, which was caused by excessive blood loss. Lin Xiufang collapsed at the entrance of the door. The two old people were stabbed in the heart in the sofa of the living room.
Zhang Yang was in his room. According to the picture, he was stabbed in the back while playing games with a headset. Only his wound was stabbed in the back. The others were stabbed in the chest and died in the heart.
"Jinnan, we investigated Zhang wangguo's interpersonal relationship for several days, and found that the project money he took over now had run away from the developer, and he didn't get the money. There were workers begging for it, but they didn't give it. There were about 100 of them. It took some time to investigate. I investigated them, and no one proved where they went that night. But on weekdays, Zhang wangguo is a good man and a righteous man. Even if he doesn't receive money, Zhang wangguo is selling their buildings and his car. How can he compensate them? These people have no reason to kill him at this time, so now some of the cases have no clue. "
"The murderer should have been an acquaintance. The murderer made a surprise attack and they didn't react. So from the wound, some of them were unprepared. However, the murderer was well prepared. He knew the work and rest of the Zhangjia people very well and chose to do the crime when they were all at home. According to the scene and these pictures, the murderer was young and bulky, He has a lot of strength. Judging from the wound, the murderer should be left-handed. He didn't search the scene, nor did he lose any important cash or valuables. The person who came here is a vendetta. He should have a deep hatred with Zhang. " Qi Jinnan also felt that the case was very complicated. The murderer didn't do it immediately, and the target was very strong.
The deceased's interpersonal relationship is complex, and it will take some time to investigate. She frowned, looked up at Ye Yufeng and said, "don't just stare at Zhang wangguo's interpersonal relationship investigation. Zhang Hong's interpersonal relationship should be investigated. Zhang Yang, Lin Xiufang and Zhang Jia's two elders should also be investigated. Those who have had worries and disputes should understand."
"It's understandable that you suspect that the murderer has a grudge against Zhang Hong, but the second elder of Zhang family has also investigated. They are so old. Who can they provoke? They are saying that two old people stay in the elderly activity center on weekdays, and the old lady dances in the square at night..." Ye Yufeng is really one of the first two big now. This case is very sensational. The superior leaders attach great importance to it and order him to solve it as soon as possible.
"Everything is possible. Not only the two old people are investigated, but no one can be left behind." Looking at Ye Yufeng's listless appearance, Qi Jinnan knows that these days he has been depressed for a long time after knowing that Lin Haiyan is the sixth master. This is also the case that makes him have no time to be sad.
"All right! Then I'll take someone with me. If you don't feel well, don't be stiff. If you have a sofa, take a rest. " Ye Yufeng comforted her, then turned to investigate.
After ye Yufeng left, Qi Jinnan put out the photos and all the reports one by one, displayed the information of the case one by one on the whiteboard, wrote the questions above and some of his own thoughts and conjectures to the other side, and then stood there quietly analyzing.
The murderer's crime route should have entered directly from the front door. He first rang the doorbell. Lin Xiufang opened the door and was stabbed in the center by him. Then he turned around and walked to the two old people on the sofa who were watching TV. His action route could be seen from the dripping blood.
After killing the two old men, Zhang wangguo came out of his bedroom and confronted the murderer. After fighting downstairs for a while, Zhang wangguo lost his mobility due to excessive blood loss. After being stabbed in the heart by the murderer, he went upstairs and killed Zhang Yang playing the game.
The murderer finally entered Zhang Hong's bedroom and stabbed the sleeping Zhang Hong into his heart. But why did the murderer finally take Zhang Hong's head away!
Is the target of the murderer Zhang Hong, or is it just to confuse the sight of the police? The murderer is cruel and seems to be violent. But judging from the scene of the crime, all this has been calculated for a long time. The murderer is very patient. He should have observed for a long time in the dark and confirmed the action track of all the zhangjias, And life after work and rest to choose the most appropriate time to enter Zhangjia, and one by one killed.
After all, there are six people in this family. If Zhang wangguo and Zhang Yang unite, the murderer may not succeed. What's more, there is Zhang Youlin, an old man. Although he is old, he has been farming for a long time, and his physical fitness is OK. In addition, there is Lin Xiufang, a woman, who can stimulate some potential when he is in danger of life, So the killer must have taken these into consideration before he chose.
By the way, how can he choose the most appropriate time? Zhang Jia lives in a house with a loft on the sixth floor. How can he observe the murderer! It must be.
Qi Jinnan thought of this and called Ye Yufeng in a hurry. Although she guessed this, she should have taken it long ago with the murderer's cautious temperament.
After contacting Ye Yufeng, Qi Jinnan drove to the scene of Zhang's accident. Half an hour later, he came to the spring light garden where Zhang lives. Entering a unit, he went to the sixth floor. These are two types of apartments, about 90 square meters, with the same area of attic above, it is a small duplex. The decoration of Zhang Jia is very exquisite, and he is also a rich family. But recently, Zhang wangguo's project lost some money, which leads to some tension in life.
As soon as Qi Jinnan arrived, ye Yufeng rushed over and ordered people to open the door before asking Qi Jinnan, "what's the matter? Have you found anything?"
"There are some discoveries, but they should be useless. I'm afraid the murderer has already taken them away." Qi Jinnan is helpless, calm but angry. No matter how much hatred there is, why do you want to kill the whole family.
