Another day passed, but Zou Zhaohui said nothing. He only said this about Li Xiaoyan's case.
"Li Xiaoyan's disappearance has nothing to do with me. I don't know where he went. If you have the ability, go find him. If you say that I killed him, then you will go find the evidence. As long as If there is evidence, I will tell you everything. If there is no evidence, this matter has nothing to do with me.”
Evidence!
The key now is evidence.
The police can basically confirm that Li Xiaoyan’s disappearance was carried out by Zhou Zhaohui, but where did he go and was he killed?
Of course, now it seems that there is a high probability that something happened to Li Xiaoyan, but where was the scene of the first crime and how did he kill the other party? How is the body disposed of after killing the other party?
No clue.
“Re-search Zou Zhaohui’s residence!”
Lu Chuan decided to re-search Zou Zhaohui’s residence.
If Zou Zhaohui is indeed the murderer, then the first place where the other party committed the murder was probably the rental house where they were located.
Judging from the surveillance, the last time Li Xiaoyan appeared in the surveillance was the night of the 17th. She never went out after coming back from get off work.
According to Zou Zhaohui’s previous statement, he went back to pick up his things on the night of the 17th, and then took a taxi and left from the underground parking garage.
But the police have already checked all the taxis near the community where Li Xiaoyan and Zou Zhaohui rented that day.
No taxi has ever taken Li Xiaoyan away.
On the morning of the 28th, Li Xiaoyan did not go to work in the beauty salon. The time of his murder was probably after the evening of the 17th.
According to Lu Chuan's request, Wang Zhaokai immediately arranged for the Xianqin criminal police from the Criminal Police Brigade to conduct a detailed search of Zou Zhaohui's residence.
However, what is frustrating is that half a day has passed and there are still no clues.
If Zou Zhaohui's home was the scene of the first crime, no matter what method Zhou Shaohui used to kill Li Xiaoyan, his body would have to be disposed of.
If the other party disposes of Li Xiaoyan's body by dismembering it, there will definitely be some blood stains left in the home.
But the criminal police from the Criminal Police Brigade scanned all the places in the bathroom, kitchen, bedroom, and living room, and found no trace of blood.
They had no choice but to ask Lu Chuan to take action.
"Bureau Lu, we scanned the whole thing with ultraviolet light and found nothing. Did the other party not kill people here? Did we guess wrong?"
High-tech Zone Criminal Police Brigade The two investigating detectives originally had average technical skills, but they had really learned a lot from Lu Chuan and the others in the past year or so.
It can be said that the two investigation detectives and Lao Bai in the high-tech zone criminal police brigade are actually about the same level, and they can take on important responsibilities when they are placed in the criminal investigation detachment.
Lu Chuan was very clear about the level of these two people. Since they did not find any blood stains or anything suspicious, it meant that the room was indeed very clean.
But if Zou Zhaohui killed someone, the most likely location would be in their rental house.
“This room should be the place where he disposes of corpses and kills people. If this doesn’t work, lift up the floor tiles in the bathroom and kitchen one by one. If the other party uses a large amount of water machine to wash it, or adopts other methods If so, it is very likely that the blood stains will be cleaned up, but there will definitely be some residual traces left. Lift up all the cracks to see if there is any possibility of blood stains remaining inside. "
No scene is perfect.
According to Lu Chuan's intuition, the possibility of the other party killing someone in the rental house is very high.
Because the two people had a conflict that night.
Zou Zhaohui was so emotional that he was very likely to kill someone directly and silence him. "Okay, let's start now."
The next two criminal policemen, like workers in the decoration team, took a small hammer to remove all the bathroom floor tiles, as well as the kitchen All the floor tiles were smashed, and some concrete or sand was extracted from the gaps and taken back for experiments.
Just when this side started to act, a very strange clue appeared on the other side of the property.
"Bureau Lu, this is the water consumption list of Zou Zhaohui's home provided by the property management. They had some water problems last month."
The deputy captain of the first squadron has been communicating with the property management company.
Early this morning, the property company called him and reported a strange situation.
“According to past circumstances, Zou Zhaohui’s household uses about 4 tons of water every month, but last month they used 7 tons of water.”
Seven tons of water!
We go out almost twice as much as before.
Lu Chuan suddenly became alert.
Last year, he handled a case.
It was originally a disappearance case, and the wife’s disappearance was reported by her husband.
As a result, there was nothing suspicious about the victim’s husband during the investigation of the case, except that their home’s water consumption was two and a half tons more than usual.
After careful investigation, it was discovered that the victim's husband was the murderer. He killed the victim, dismembered the victim, and then flushed the whole thing into the sewer.
Now, coincidentally, the water consumption of Zou Zhaohui's family has also increased sharply.
“What day?”
“The property management side has no way to determine on which day the water consumption increased sharply, but it should be in the next half month. They don’t have a specific time. The solution is for sure.”
“Let’s go to the interrogation room!”
In the interrogation room, this time, Lu Chuan will interrogate him in person.
"Zou Zhaohui, if you confess now, you can still be considered lenient."
Lu Chuan sat opposite Zou Zhaohui and got straight to the point.
“Do you know what this is?”
Otherwise, what he was holding in his hand was the water consumption list printed by Zou Zhaohui’s property management company last month.
“I can tell you clearly that our site surveyors are now carefully inspecting your home. All the floor tiles in the bathroom and kitchen have been pried open, and there are still silt and broken pieces inside. Block, experiment in progress”
"In just one day at most, the relevant experiments can be completed. If there are any blood stains, you will know once you do the experiment. In addition, there is this water consumption list. Last month, when Li Xiaoyan disappeared, your home's water consumption suddenly increased. Double the usual amount.”
“Can you explain it clearly?”
Water consumption!
Lu Chuan came out. When he took out the water consumption list, Zou Zhaohui's expression changed obviously.
"I..."
Looking at the water usage list in front of him, Zou Zhaohui knew better than anyone what he had done, and his face was ashen!
"Zou Zhaohui, this... is your last chance." (End of this chapter)
