ww.x.om Permit carefully picked up the dominoes with gloved hands, picked up a magnifying glass and observed them carefully: due to their texture, dominoes can often leave very clear fingerprints.
Under the magnifying glass, he found that the fingerprints on the dominoes were very clear. He nodded with satisfaction.
He opened the cabinet and took out his forensic toolbox - it was not brought by him from the old time and space, but made by Lingao himself.
Fingerprints could be extracted with transparent tape in the old time and space, but in this time and space, you have to think a lot differently. You can take out a small bottle of toner and gently brush it on the dominoes with a brush.
Fingerprints appeared clearly on the dominoes. There were three fingerprints worth extracting. He took out a small glass piece wrapped in tissue paper from the tool box. This glass piece was made according to special specifications, similar to that used on a microscope.
Slide. He carefully unpacked the package, making sure that the glass slide was clean and free of dirt, and took out a little glue liquid from a small bottle: the basic raw materials are beeswax and rosin, which can ensure transparency while maintaining viscosity. He used a cotton swab
He spread the glass piece as evenly as possible. Then he used the piece of glass to carefully stick the fingerprints on the domino and stick it on a piece of white cardboard.
In this way, he quickly extracted three fingerprints. Although the fingerprints were all incomplete, they were enough to provide comparison.
There were fingerprints attached to the autopsy report, and he compared them one by one with a magnifying glass. Soon he made a new discovery.
One of the three fingerprints does not belong to the deceased!
This discovery greatly excited Xu Xu. The fingerprints of another person on the domino were probably left by the murderer's accomplice!
Dr. Zhong kept watching and saw Xu Xu's happy expression, knowing that there was a breakthrough in the case. He asked: "How is it? Is there any progress?"
"We may have gotten the suspect's fingerprints." Quan Quan was very excited, "This way we can accurately find the murderer!"
Zhong Lishi looked at the dominoes with interest. He remembered that Zhong Xiaoying would sometimes play Pai Gow alone at night when he had nothing to do. Since he knew how to play, he might be able to see some other tricks. He immediately suggested that Zhong Xiaoying also play Pai Gow.
Called to see this physical evidence.
Permission was absolutely necessary - although he felt it was meaningless, it would not offend Dr. Zhong's face. He immediately called someone to fetch Zhong Xiaoying.
Zhong Xiaoying put on her gloves, looked at the domino carefully, and said to Xu Xu: "This is a gambling tile..."
Isn't it nonsense that Xu Xu was thinking? Zhong Xiaoying could see what he was thinking. She added: "I mean, this is a card used by gamblers."
Xu Xu nodded and asked: "Do you have anything to say about this kind of card? For example, what secret code does it represent?"
Zhong Xiaoying said: "If they use the value of this card as a secret code, I won't know. But -" she took the card, looked at it carefully, and said to Xu: "This card is used by gamblers.
They often forge casino cards to cheat people." She said.
"Look, there's a mark on this card..."
"mark?"
"People in casinos are certainly not fools. In order to prevent others from cheating, they all put some kind of mark on their cards. They look like the same cards, but in fact they are different from each other. But smart gamblers often even
Marks can also be imitated, so actually this method can only protect against beginners..."
After a while, Zhong Xiaoying pointed to a corner of the card and said to Xu Xu: "These gaps are man-made. There must be a casino with the same gap on the card. This person must be a frequent visitor to this casino..."
Xu Xu took out a magnifying glass and looked at it carefully. Sure enough, there were several tiny scratches on the corner of the card. If you don't look carefully, you can't notice it at all.
"It's really yours." Xu Xu praised, "If it weren't for you, we wouldn't have known there was such a trick in it."
"Uncle, you are overly praised." Zhong Xiaoying said modestly, "There are many casinos, and it is of no use just knowing that they are casinos and where they are."
"At least there's one more clue." Xu Xu didn't take it seriously, "I didn't expect you know a lot!"
Zhong Xiaoying smiled bitterly: "My eldest brother is a gambling addict - if not for this, he might not have declined so quickly..." She said with a very lonely look.
After sending Dr. Zhong and his daughter away, Xu thought twice and decided to conduct a comprehensive screening of all migrant fishermen and sailors stranded in Kaohsiung and compare their fingerprints one by one.
He informed Mingqiu and Wei Bachi of his plan. Of course Mingqiu asked him to "act cheaply". As for Wei Bachi, he expressed his "full support" enthusiastically.
"Don't worry, I will fully cooperate with you on this matter." Wei Bachi looked distressed. "What happened in Kaohsiung shows that we did not do our job well and failed to live up to the trust of the Senate.
I'm very sad." He said with a sad expression.
That night, he went to the Customs construction site in person and had a cordial discussion with Dr. Zhong for more than an hour on the construction work of the Customs bell tower and other projects of the Ministry of Science and Technology in Kaohsiung, fully expressing his admiration for Dr. Zhong.
Love, of course, did not forget to praise Zhong Xiaoying for being "wisdom and courageous".
Early the next morning, Quan Quan led a large group of heavily armed soldiers toward the dock. This was the entire base service company.
The pier is the same as the commercial street. It has been completely blocked since the incident, and no one is allowed to enter or exit. Wei Bachi mobilized a large number of North Korean security forces to guard the surroundings and controlled all entrances and exits. Those who have landed must stay in the inn.
Those who have not landed will remain on the ship and are not allowed to move around at will.
"Hurry! The first platoon goes over there! The second platoon blocks the intersection! Hurry!" Following the permission order, the soldiers of the service company quickly controlled the key points of the pier. They surrounded them like iron barrels. They were already frightened.
The people were frightened and at a loss when they saw this scene.
A naturalized citizen climbed onto a pile of cargo, grabbed a metal microphone and shouted at the people on the fishing boat: "Don't panic! Don't panic! We are ordered to investigate the case and will not endanger everyone's personal safety. Please land immediately.
Then we formed 20 teams in order to receive inspection..."
He repeated these words repeatedly, and in accordance with the pre-issued orders, the security forces took big sticks and began to direct the crowd to get ashore and queue up. The people on the dock began to follow his instructions. After a while, 20 long queues gradually formed.
The soldiers followed the permission's instructions and began to search the people on the dock one by one. At the same time, everyone was asked to leave fingerprints of the same finger as the fingerprints obtained.
Suspected people were pulled out from time to time to prepare for further screening. People waiting for the search could not help but feel worried. Although no one dared to speak, the sense of depression in the air reached its peak.
The search lasted all morning, and more than 200 people were searched and evidence collected, and more than a dozen suspects were detained.
Allow someone to interrogate the suspect first, and then compare the fingerprints yourself.
Comparing fingerprints is a boring and low-accuracy task. Before there was an automatic computer fingerprint comparison system, the probability of finding a criminal based on fingerprints was very small - even if the criminal had left a fingerprint record, it would be difficult for fingerprint comparison personnel to do so.
Matching people can be found in a vast array of file cards. Therefore, in the past, fingerprint comparison was mostly used to identify criminals.
Fortunately, the number of people involved in the investigation is limited, and only one fingerprint needs to be compared. Even so, comparing fingerprints is still a very arduous task.
The hard work paid off, and when he compared the 111th person, he found matching fingerprints.
"That's him!" Quan Quan shouted, and he immediately said to the policeman on call: "Arrest No. 111 immediately! Send him to the police station!"
"He has been arrested..." the police said.
"What?"
"He carries a set of Pai Gow dominoes in his carry-on luggage - you have taken care that anyone with Pai Gow dominoes and hollow bamboo tubes such as flutes will be detained for screening."
"That's great." Xu Xu thought that this time he would be worthy of more honors, "Send him immediately!" He remembered something and added, "The other people on his boat will also be arrested together."
"Yes, Chief. What about the other suspects?"
"Send them too." Li Quan decided not to let go of any suspicious clues.
Wei Bachi was discussing the progress of the investigation with Zhong Lishi at the police station when he suddenly heard several shouts from outside. Two policemen tied up one person and pushed him to Nanhai's office.
Wei Bachi asked: "Has the person been found?"
"That's right." Xu Quan was very excited. This breakthrough had been grasped, and the case was solved just around the corner. "There are still about ten suspects, so we have to spend some time to interrogate them all!"
But the one whose fingerprints matched must be a key target. He ordered that the person be sent to the interrogation room immediately to prepare for personal interrogation.
Wei Bachi and Zhong Lishi wanted to participate in the interrogation in order to show that they would do their part. Xu Xu had no choice but to agree.
"I have also learned interrogation techniques and can help you with the interrogation first." Wei Bachi was very enthusiastic.
"Okay. You first ask about his basic personal information and the origin of the dominoes he carries with him."
Li Liang still had a lot of things to deal with, especially the fact that he had to conduct an investigation on the people on the fishing boat where the suspect was on so that he could grasp the person's background information before starting the key interrogation. He knew that Wei Bachi was well-read,
He can be regarded as someone with a bit of food in his stomach.
Wei Bachi asked someone to pour a glass of water for the suspect, and then said to the man in a friendly manner: "Don't be afraid, our Song Dynasty is a legal society, and we will not do anything to you. We have something to ask you, please answer us truthfully
..." Wei Bachi asked briefly about the man's name and occupation. He found out that his name was Li Shun, a native of Fujian. He was a man who worked odd jobs on a fishing boat. When he asked about the origin of the cards in detail, he didn't want Li Shun to ramble on.
He just refused to tell the true origin of the cards, only saying that he used them for fun.
