City: The Strongest Detective!

Wang Dalu's family.

At this time, Hao Shuai was following the evidence experts to conduct a evidence search on Wang Dalu's home.

First, look for blood marks, which are traces left by blood.

Once the blood has fallen to the ground, it cannot be scrubbed off unless it is removed with a chemical agent.

Several colleagues each held a bottle of luminous ammonia, sprayed it everywhere, and then irradiated it with purple light.

The so-called luminous ammonia, also called luminol. It is a strong acid, which has a certain irritating effect on the eyes, skin and respiratory tract. During the examination of blood stains, luminous ammonia reacts with heme in the blood, showing blue-green fluorescence. The sensitivity of luminol can reach 1 in 1 million, i.e. 1 drop of blood mixed with 999999 drop of water can also be tested.

"Look, there's a bloodstained ...... in this seat

."

Zhang Yihan was the first to find the traces, at the bottom of the sofa in the hall, found a blue-green trace of about 0.5 square meters, and also used a magnifying glass to find a small black blood clot. Later, it was found that there were impact marks on the corner of the sofa, and there was a trace of blood clotting remaining.

Forensics, bagging, sealing, and waiting to go back for DNA comparison to see if it is the deceased Zhang Quan.

After finding this, nothing useful was found in the room.

Subsequently, everyone came to the underground garage of the community and found Wang Dalu's private car, a Mercedes-Benz, and sure enough, they found blood stains.

Then the evidence is collected, bagged, and sealed.

Subsequently, everyone made another major discovery in the car.

On the seat of the car, after careful search with a magnifying glass, a cotton and linen fiber was found, which was most likely the remains of the rope that bound the deceased in the first place. In this way, things can be brought back to the police station for material comparison, as long as the ingredients can be compared, it can become a strong evidence to support Wang Dalu's murder.

"By the way, check this dash cam and see if there is a record. "

"It shouldn't be possible, did the murderer still drive the dash cam when he committed the crime?"

After checking the dash cam, sure enough, it was blank during that time, and the recorder was broken.

After the evidence was collected, the group went to the police station to do a test and comparison, and it took less than an hour to find that the cotton and linen fibers on the car matched 100% of the fibers that remained on the body of the deceased when he died.

And the blood DNA is exactly the same as the DNA of the deceased Zhang Quan.

At this moment, the first scene was confirmed that it was at Wang Dalu's house.

And the murderer is also about to come out.

......

When the two pieces of evidence of blood stains and fibers were placed in front of Wang Dalu, Wang Dalu was dumbfounded and muttered to himself: "Impossible, how is it possible? There must be something wrong, how can there be these things in my car?!".

Bang!!

Team Zhang slammed the table and glared at Wang Dalu angrily: "Hmph, this is all conclusive, what else can you deny?"

Suddenly, Wang Dalu shouted: "No, Zhang Quan was not killed by me, but committed suicide, I was wronged, Zhang Quan must have wanted to drag me into the water with death!"

Team Zhang sneered: "Hmph, you still dare to quibble, these evidences show that it was indeed you who killed!".

Wang Dalu hurriedly shouted: "Wronged, really wronged!".

......

At this time, in the interrogation room on the other side, Dong Li, the wife of the deceased, was crying in front of the interrogators.

"I know that all this was Zhang Quan's deliberate suicide and framed us, and he will not let us go if he dies...... His cowardly waste has always been a piece of waste, he can't do anything, he gets angry with me if he doesn't do it well, he drinks alcohol, and beats me with a whip...... I couldn't stand it anymore and wanted to divorce him, but he wouldn't ......

."

"Wang Dalu is very good, a hundred times, a thousand times, ten thousand times better than Zhang Quan's waste, so I got along with Wang Dalu, but Zhang Quan still knew about it, I originally thought that Zhang Quan's would agree to my divorce, but I still didn't agree to ......

."

Dong Li cried all of a sudden, and talked a lot about the past like pouring beans.

The interrogation expert felt that the opportunity could not be missed, so he deliberately guided Dong Li, hoping to come up with some clues.

Dong Li was guided like this, and really said a lot of valuable things.

"I really want to kill him sometimes, it's a hundred times, I really can't live this day, I sometimes think about killing myself...... This waste has no ability at all, his so-called dealer, if it weren't for Wang Dalu's help, he would have lost everything a long time ago, every time he asked Wang Dalu to buy goods, he refused to give money, Wang Dalu because I felt that I owed Zhang Quan, so I didn't ask for debt...... This kind of person is better ...... dead."

"I can die, after all, I don't want to live for a long time, but Wang Dalu still has a wife and son at home, he is wronged, he can't die...... And I seduced him in the first place, and he also kept a distance from me, it was I who was sorry for him, sorry for his wife and son......".

Dong Li said and spoke, feeling a little mentally broken, and the will to die was born, which made the interrogation expert have to stop the interrogation.

......

......

The meeting of the facts of the case was held again.

Everyone, re-report the information in their hands so far.

Zhang Guoan finally summarized the report: "Judging from the current situation, the evidence points to Wang Dalu as a murderer, first, evidence was found in his car, and second, he did not have an alibi. Third, there is a motive for committing the crime...... However, judging from the interrogation, Wang Dalu has been shouting that he has been wronged, and he really doesn't want the murderer, unless he is an old fritter...... Let's start the discussion, let's talk freely and see if there is anything that is missing. "

The young Qin Li took the lead in raising his hand: "I think the deceased should have been killed by Wang Dalu, and Dong Li's statement is just confusing our sight and covering our eyes." "

Zhang Yihan: "I think the possibility of suicide cannot be ruled out, Dong Li's words feel very true, not like lying, this Zhang Quan is likely to use suicide to drag Wang Dalu and Dong Li into the water and take revenge." "

Wu Jianguo: "We can't ignore the phone booth ...... that provided clues."

One by one, they spoke enthusiastically, saying the conjectures in their hearts, handling cases requires imagination, and it is more difficult to investigate cases if they are too rigid, perhaps a flash point is the key to solving the case.

In the midst of this heated discussion, the captain Zhang Guoan suddenly found Hao Shuai sitting there with a frown, and he had not spoken.

Zhang Guoan: "Hao Shuai, what is your opinion? "

Hao Shuai thought for a while: "I don't feel right, I feel that there is a place that I haven't taken into account ......."

Zhang Guoan: "What place?".

Hao Shuai suddenly said: "Captain, I want to personally interrogate Wang Dalu and verify what I think." "
