Chapter eight hundred and seventy-two half fingerprints for the moon
"Hello, Mr. Zhou, we are the Public Security Bureau. Because your son is suspected of a case 17 years ago, the public security organs need to search his own items. This is a search warrant, please cooperate!"
Not long after Jiang Hao left Uncle Zhou's house, Hao Lei and the others took Bai Xiu to the scene and began to enforce the law.
Uncle Zhou was excited when he saw the police coming to the door and acted seriously, and wanted to obstruct the law enforcement.
Seeing this, Wu Qinyi winked at Bao Yun'er and asked her to take the old man aside to do ideological work with her.
Hao Lei, who was good at on-site investigation, took the rest of the team members into the room and began to search for all items related to Zhou Yajun.
"Yan Fang, forensics is your best choice, it depends on you this time."
Hao Lei said with a smile to Yan Fang beside him. The latter nodded slightly, holding the ultraviolet device borrowed from other units in his hand, and walked into the house first.
They first need to identify which items belong to the old man and which items belong to Zhou Yajun.
Since the other party has been away from home for seventeen years, relatively speaking, there are almost no traces of his life.
The main purpose of the police coming this time is to hope to collect his fingerprints.
Fingerprints are mainly composed of sweat, oil, cholesterol, amino acids, and proteins.
Parts of these substances will gradually disappear over time. Use chemical technology to collect fingerprints to accurately confirm fingerprints left within the past one or two to 15 days.
If it takes too long, this method will not work, let alone Zhou Yajun has been away for seventeen years.
But it doesn't mean that all fingerprints will disappear.
Just like the fingerprint on plastic, it will not disappear. As long as it is not wiped by water or cloth, it will not disappear. Even if there is dust, use a small brush to brush away the dust, and the fingerprint will still exist.
At this time, you need to use the ultraviolet light assistance from Yan Fang.
"This one has a fingerprint, I don't know if it's the suspect!"
Yan Fang used the equipment and found a clear fingerprint on a cabinet door, so he immediately used a small brush to clean it up, and then used professional tools to extract the fingerprint.
As the investigation deepened, several fingerprints were discovered one after another.
Some of the fingerprints were not complete, but they did not dislike it. Even if there was only half of them, they also collected them.
The search continued until the evening, and until nothing was missing, Hao Lei and the others stopped the team.
All the collected fingerprints were quickly brought back for systematic comparison.
Time is tight, and everyone doesn’t care about going to and from get off work anymore, and they are waiting in the office for comparison results.
This result may be good news, but it may not be good news.
After all, the police only had one fingerprint of the suspect. They had to be lucky and happened to collect the same fingerprint, which was useful.
As the comparison work progressed, everyone was also very nervous, and they all hoped that the comparison result would be as they wished.
"The result is out, and all the complete fingerprints are not successfully compared."
When Wu Qinyi saw the system's results, she found that the several complete fingerprints collected were not successfully compared.
"What should I do?"
Everyone was a little discouraged for a moment and didn't know what to do.
"What's the hurry? Don't we have some incomplete fingerprints? This incomplete fingerprint computer cannot identify and compare, so we can only rely on manual comparison."
Yan Fang has not given up yet. The complete fingerprint can be quickly analyzed and identified by computers. If it is a broken fingerprint, the system recognition level is not high and it will not be helpful.
Therefore, they can only use ancient methods and manual comparisons, just like puzzles, which are very tests people's eyesight.
When everyone heard that they wanted to compare the incomplete fingerprints in person, they immediately felt that their blood pressure was rising.
"We must come up with a result today. You must know that our time will be less than one day after one day."
Peng Yufei and the others from a group also came to help.
Although they were looking for another clue, the fingerprints they collected were all complete fingerprints and can be compared in batches using computers.
At this time, seeing the second group in trouble, he naturally did not dare to get off work first, but chose to stay together to "share weal and woe".
At 10 o'clock in the evening.
The lights are still on in the expert group's office.
Everyone was lying on the desk, under the desk lamp, comparing the collected fingerprints.
After seeing too much fingerprints, they could even draw them with bare hands.
"Ah~ I was so confused about my eyes. How are you doing? Is there any result?"
"These incomplete fingerprints are irregular and not square, so it's not so easy to compare."
While comparing and communicating, everyone relieved their mental fatigue, but the movements in their hands did not slow down at all. They just stood up and stretched their backs and relaxed their spine.
"I seem to have found it!"
Suddenly, they heard someone say they found it, and immediately turned their heads happily to look at the man who spoke out:
"Yan Fang, is it true?"
Everyone rushed over and surrounded Yan Fang.
"You wait a moment, wait for me to deal with it, so that you should see it more clearly."
After saying that, Yan Fang uploaded the broken fingerprint to the computer, enlarged the complete fingerprint on the murder weapon on the projector, and then dragged the broken fingerprint onto the complete fingerprint.
As the incomplete fingerprints slowly cover until they move to the lower right corner of the entire fingerprint, the fingerprints gradually overlap with patterns.
"It's true, Lao Yan, your eyes are really ignited and golden eyes. You have discovered this so hidden!"
After really finding the fingerprint, everyone's pressure was suddenly reduced by half.
Although there is only half a fingerprint, it is enough to determine that Zhou Yajun is the suspect they are looking for.
Seeing this, Peng Yufei immediately stated: "It seems that this Zhou Yajun is really a suspect. According to the instructions of Team Leader Jiang, our group one will automatically be incorporated into the second group for investigation and will do our best to arrest the suspect Zhou Yajun. ”
"Okay, this time it's our first time to solve the case. I hope everyone will work hard to arrest the suspect within the specified time."
The people who were still tired just now were excited and fighting spirit, and their state was instantly full of blood.
Bai Xiu was sincerely happy for them to see that they were really likely to complete the case under this difficult mode.
After looking at the time, it was almost half past ten, so Bai Xiu said to them:
"Let's just stop here tonight. Everyone is tired. Go back early to rest and you will have the energy to continue pursuing tomorrow."
"Senior sister is right. Everyone should go back and rest. In the next few days, everyone will be cheered up. After all, now, we don't know where he has been hiding!"
