The place where the life case occurred was also within the scope of Wang Sunxu's activities. When Lin Qiupu and his party arrived, Peng Sijue was leading people to collect evidence at the scene.
"What's the situation?" Chen Shi said.
Lin Qiupu gave this distracting guy a white look, and said, "Captain Peng, explain the situation!"
Peng Sijue said: "It was the hostess of this house who died. The time of death should be around 12 noon. She was stabbed to death by a knife in the middle of the afternoon nap. Her husband took the child out and found out and reported the case at 4 pm... Half of the drink, and that kind of bottle cap."
Lin Qiupu picked up half of the drink on the coffee table, unscrewed it, and took a look. There was a biscuit box on the lower level of the coffee table, which contained various receipts and ticket stubs, including a list of supermarkets, proving that the family had indeed bought this drink.
In the bedroom, the hostess lay down on the bed in her pajamas, and her death was very similar to Wang Sunxu's methods.
Outside the door, her husband was crying, and many neighbors were comforting.
Lin Qiupu asked her husband to come in for inquiries, and he waved his hands desperately and said, "I dare not come in, I don't dare to come in. When I see my wife, I will..." Then, the husband wiped out some sad tears.
Lin Qiupu went outside to ask questions.
Chen Shi was very interested in the line of footprints that the technical police found on the floor of the living room. It was obviously a woman's barefoot print. Only the first half seemed to be walking to the door with her feet in her arms and walking back.
Chen Shi came to the bedroom and did not look at the corpse, but squatted on the ground to study the pair of plush slippers. One of the slippers was beside the bed, and the other was kicked under the bed.
Chen Shi pondered: "The hostess probably didn't find the slippers, so she went to open the door barefoot, but if a stranger came in, the footprints on her return would not be so neat."
Lin Dongxue lowered her voice and said, "Do you suspect that it was a hitchhike to kill?"
"Lao Peng, do you think Wang Sunxu did this?" Chen Shi asked.
"The technique is relatively close, and there is no deep autopsy yet, so it's not clear."
"Go check the knives in the kitchen."
So the three came to the kitchen and sprayed all the kitchen knives with reagents, but no human blood was found on them.
Chen Shi pointed to the sink: "Here."
There is also no blood in the washbasin.
Then came the toilet. As soon as he opened the toilet, Chen Shi smelled a heavy smell of disinfectant. There was no blood test here, but Peng Sijue judged based on his experience in handling the case that the toilet was cleaned vigorously.
Lin Dongxue frowned: "Would you like to be so gloomy, because it is the husband who reported the crime, so you suspect him?"
"It's not that we are dark. The scene is suspicious." Chen Shi walked to the refrigerator, opened the refrigerator, picked up the row of drinks and checked them one by one. It’s hard to say why the master did it. Why did she unscrew them all and pick out the killer bottle cap to drink, and put it on the coffee table after drinking, as if deliberately summoning Wang Sun Xu to come."
Peng Sijue said: "Let's test who is drinking the drink!"
"Good idea!" Chen Shi praised.
Peng Sijue compared the deceased’s saliva enzyme with the bottle mouth, and found that they did not match. He came outside, and his husband was vividly describing Lin Qiupu’s scene at the time of the incident. Peng Sijue said, “open your mouth.”
"what?"
Lin Qiupu knows, but deliberately said: "Nowadays DNA has to be sampled to facilitate the elimination."
"Oh oh oh, understanding."
After collecting her husband's salivary enzyme, Peng Sijue made a simple identification with a test box. He said: "It is roughly the same, it is almost a person in all likelihood."
Chen Shi said: "The wife was killed, and the husband calmly drank half of the drink and put it on the table, and then reported the crime. This is obviously illogical, and the killing didn't run away!"
"It's so dark! This kind of man." Lin Dongxue said disgustingly.
The three people came to the door, and the husband was still eloquently describing, Lin Dongxue whispered a few words in Lin Qiupu's ear, and the husband noticed something wrong and stopped talking.
Lin Qiupu said, "Your last name?"
"Liu."
"Mr. Liu, I would like to ask you to go back with us to assist in the investigation."
"Assist in the investigation?" The husband raised his voice and looked at the neighbors, "Is there anything I can't ask here? My family has suffered such misfortunes. If you don't catch the murderer and take me back, you think what's wrong if you don't know. It’s so good to talk about it!"
"I hope you cooperate."
"Aren't you suspicious of me? Why are you policemen? You know you are taking the common people off. I told you. At that time, my son and I were walking outside."
Chen Shi said: "You should understand the meaning of the four words'assistance in investigation'.
"I don't know what you are talking about..." The husband was sweating, and suddenly he ran up the stairs with his leg pulled out, and he fell on the stairs with an oops.
The police immediately rushed forward and tormented him.
Chen Shi smiled and said, "What am I talking about."
Lin Qiupu looked at him coldly, "Don't interrupt, in case the suspect is injured, you will be responsible?"
Chen Shi shrugged, "There is nothing wrong with me today, I'm going back, see you tomorrow."
Amidst the neighbors’ discussions, the husband was taken away. The man was weak in character and could not hold back Lin Qiupu’s psychological offensive in the interrogation room. He immediately recruited the truth.
It turned out that he wanted to kill his wife a long time ago, but he couldn't find a suitable method. This time this serial killing happened suddenly, he thought it was a godsend, so he went to the supermarket to buy a bunch of this drink, and he won the prize. .
His wife has the habit of taking a nap. At noon, he took the child out for a walk. When the child was playing in the children’s playground, he ran back and stabbed his wife to death with a prepared knife. With the murder weapon, he continued to play with the child casually, then went home at four o'clock, "found" the murder and reported it to the police.
I thought it would be seamless, but I didn't know that in the face of police investigation and experience, it was full of flaws.
At eight o'clock in the evening, Chen Shi had just arrived home and received a text message from Lin Dongxue: "Hit a ride to kill, and he has been detained."
Hitchhiking to kill is the most unreliable thing. The police have been exposed to similar cases and suddenly a Li ghost pops up. It is easy to gang up. Moreover, the police cannot disclose all the details of serial killings. These details are known to the police and the murderer. But outsiders don’t know.
Chen Shi wanted to say this, but it was too troublesome, so he only replied: "It was a hard day today. Go home early to rest and pay attention to safety on the way."
"Okay, see you tomorrow." In Lin Dongxue's straight reply, Chen Shi could also feel the warmth of his lover.
Tao Yueyue was doing homework at home. Chen Shi was exhausted today and made a bowl of noodles casually. Tao Yueyue came out and asked, "Did the bad guys be caught?"
"No, you remember to go with your classmates when you go home these two days."
"Is the bad guy that person?"
"no."
"Uncle Chen, I'll get you a drink!" Tao Yueyue quietly took out a paper bag from her pocket...
