Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Another day passed, and Zou Zhaohui said nothing. This was the only sentence he had to say 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 got rid of him, then you can find evidence. As long as there is evidence, I will tell you everything I know. If there is no evidence, this matter has nothing to do with me."

evidence!

Now the key is evidence.

The police are basically certain that Li Xiaoyan’s disappearance was caused by Zhou Zhaohui, but where did she go and was she killed?
Of course, it seems that Li Xiaoyan is in trouble, but where is the first crime scene? How did he kill her? How did he deal with the body after killing her?

No clue.

"Re-search Zou Zhaohui's residence!"

Lu Chuan decided to search Zou Zhaohui's residence again.

If Zou Zhaohui is indeed the murderer, then the first place he killed people would probably be the rental house where they were staying.

According to the surveillance footage, the last time Li Xiaoyan appeared was on the evening of the 17th, and she never went out again after she came back from get off work.

According to Zou Zhaohui's prior statement, he went back to get something on the evening of the 17th, and then took a taxi out of the underground parking garage.

However, the police have already checked all the taxis near the residential area where Li Xiaoyan and Zou Zhaohui rented a house that day.

No taxi has ever taken Li Xiaoyan away.

On the morning of the 28th, Li Xiaoyan did not go to the beauty salon to work, so he was probably killed after the evening of the 17th.

In accordance with Lu Chuan's request, Wang Zhaokai immediately arranged for the Xianqin detectives from the Criminal Police Brigade to conduct a detailed search of Zou Zhaohui's residence.

However, what is frustrating is that after half a day, there is still no clue.

If Zou Zhaohui's home was the first crime scene, no matter what method Zhou Shaohui used to kill Li Xiaoyan, his body had to be dealt with.

If the other party dismembered Li Xiaoyan's body, there would definitely be some bloodstains left in the house.

However, the detectives from the Criminal Police Brigade searched every place including the bathroom, kitchen, bedroom and living room, and did not find any signs of blood residue.

There was no other way, they could only ask Lu Chuan for help.

"Director Lu, we scanned the entire area with an ultraviolet light and found nothing. Did the other party not kill anyone here? Did we guess wrong?"

The two on-site investigators from the High-tech Zone Criminal Police Brigade originally had a relatively average technical level, but they have learned a lot from following Lu Chuan and his team over the past year.

It can be said that the level of the two on-site investigating detectives and Lao Bai in the High-tech Zone Criminal Police Brigade is actually about the same, and they can all take on important tasks if 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 suspicious objects, it meant that the room was indeed very clean.

But if Zou Zhaohui killed someone, the most likely place was in their rental house.

"This room should be where he disposed of the bodies and killed people. If that 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 to flush, or adopts some other method, it is very likely that the bloodstains will be cleaned up. However, there will definitely be some residual traces left. Lift up all the gaps and see if there is any possibility of bloodstains in the residues inside."

There is no perfect scene.

Based on Lu Chuan's intuition, there is a very high possibility that the other party committed murder in the rental house.

Because the two people had a conflict that night.

Zou Zhaohui was very emotional, and there was a high possibility that he would kill someone to silence them. "Okay, let's get started."

Next, the two detectives, like the workers from the renovation team, took a small hammer and smashed all the bathroom and kitchen floor tiles. They extracted some concrete or sand from the gaps and took them back for experiments.

Just as the action was beginning on this side, a very strange clue appeared on the property side.

"Director Lu, this is the water usage list provided by the property management. There were some problems with their water usage last month."

The deputy captain of the first squadron has been communicating with the property management.

Early this morning, the property company called him and reported a strange situation.

"Based on past experience, Zou Zhaohui's family used about 4 tons of water per month, but last month they used 7 tons of water."

Seven tons of water!
It’s almost twice as much as before.

Lu Chuan suddenly became alert.

He handled a case last year.

It was originally a missing case, and it was the husband who reported the case because the wife was missing.

As a result, during the investigation of the case, the victim's husband did not appear to be at any suspicious location, but their family's water consumption was two and a half tons more than usual.

After careful investigation, it was discovered that the murderer was the victim's husband. He killed the victim, dismembered the victim, and then flushed the whole body into the sewer.

Now, coincidentally, Zou Zhaohui's family's water consumption has also increased sharply.

"When?"

"The property management company can't confirm the exact day when the water usage increased sharply, but it should be in the next month and a half. They can't be sure of the exact time."

"Let's go to the interrogation room!"

In the interrogation room, this time, Lu Chuan personally interrogated the patient.

"Zou Zhaohui, if you confess now, it can be considered as a mitigating circumstance."

Lu Chuan sat opposite Zou Zhaohui and went straight to the point.

"Do you know what this is?"

Otherwise, what he was holding in his hand was the water consumption list printed out by the property management company for Zou Zhaohui's home last month.

"I can tell you clearly that our surveyors are now conducting a thorough inspection in your home. All the floor tiles in the bathroom and kitchen have been pried open, and the mud and debris inside are being tested."

"It will take at most one day for the relevant experiments to be completed. We will know if there is blood inside once the experiment is done. In addition, there is this water consumption list. Last month, when Li Xiaoyan disappeared, your family's water consumption suddenly increased to twice the usual amount."

"Can you explain it clearly?"

Water consumption!
Lu Chuan pointed out that 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 turned pale!
"Zou Zhaohui, this... is your last chance." (End of this chapter)
