The DNA similarity between the suspect Li Haidong and the deceased reached 99.99%, indicating a mother-son relationship. The technical team's identification results came out the next day. Although everyone was mentally prepared, they were still shocked and speechless by this result.
What kind of hatred or resentment exists between mother and son that could lead to such a human tragedy? This is a question hanging in the minds of all members of the task force, but they all have a tacit understanding and no one has asked a word.
Great sadness and speechless. Whatever you ask or say is redundant.
The weather seemed to have turned cooler all of a sudden, and everyone suddenly felt a little chillier in the air.
"Is Li Haidong Wang An or Wang Kang? We don't know yet, so we will call him Li Haidong for the time being." In the conference room, Li Zhudao was reporting on the investigation.
Attending the meeting today were not only Captain Ma, but also top leaders of the Municipal Bureau and several deputy directors. The Baitu copy was inherently bad in nature and had a very bad impact. In addition, Captain Ma suddenly reported to the city bureau the mother-child relationship between the suspect and the deceased. This made Director Liu Jinsong, who was giving orders behind the scenes, unable to sit still any longer. This criminal case not only trampled on the bottom line of the law, but also trampled on the bottom line of moral ethics and public order and good customs. Director Liu immediately issued a hush-hush order and strictly ordered that confidentiality should not be compromised. Anyone who leaked the information would be questioned. The overwhelming public opinion from all sides has made him overwhelmed, and the pressure from provincial and municipal leaders has overwhelmed him. Before the case is truly solved, once such impactful negative news is leaked, it will only add fuel to the fire of public opinion. , adding insult to injury. Whether it was due to work needs or the complexity and severity of the case, he felt it was necessary to take command from the front and listen to the work reports of front-line case handlers.
After Li Zhudao reported the previous work and the doubtful points of the case one by one, he began to describe the difficulties in the current investigation of the case: "At present, we still have too few clues and evidence. The suspect Li Haidong and the deceased are mother and son. , but we currently have no direct evidence to prove that the deceased is Wang Fang, and apart from the photo on the ID card, there is no other strong evidence to prove that Li Haidong is one of the Wang brothers."
"What do you mean?" asked Zhang Xiao and Deputy Director Zhang, who were in charge of criminal investigation.
"The face and fingers of the deceased were destroyed, and all documents related to identity information were also destroyed. No fingerprint information could be extracted from Room 1304. In other words, we cannot prove the identity of the deceased based only on her body. The technical team did not extract any hair clues from Building 17 of Harmony Community. We tried to prove that the deceased was the owner of Building 17 of Harmony Community through DNA comparison and verification, but it was not possible. And between the brothers Li Haidong and Wang During the period, except for the exact same ID photo, there is no other strong evidence to prove that Li Haidong is one of the Wang brothers, and there is no other clues and evidence that allow us to distinguish whether he is Wang An or Wang Kang." Li Zhudao said.
"This... Li Haidong can really erase all traces?" Deputy Director Zhang's tone was full of doubt. Everything we walk through will leave traces, and no matter what kind of contact humans have made, they will definitely leave trace evidence. This is pretty much the cornerstone of modern criminal forensic science. Deputy Director Zhang's subtext is that he thinks the investigators made any omissions during the investigation process. After all, even computer machines make mistakes sometimes, let alone people.
Deputy Director Zhang's words made some comrades in the task force look more or less unhappy. Everyone is so busy that they haven't had a good sleep for two days and nights in a row, and they haven't even had time to take a poop. Now they are being criticized for not being careful enough in their work, which would make anyone else feel uncomfortable. Especially Xiao Wang, his nostrils were turned up in the sky after hearing this. Fortunately, he was not of a high level and was sitting in the back row, so no one noticed.
"Technical team, to the team leader, please report the technical identification work to the bureau leader." Ma Hongwen, the detachment leader, had no expression on his face and could not see any emotional changes. He responded directly.
The leader of the technical team is Xiang Juan. Team Leader Xiang had previously been a "pornography appraiser". When he started telling jokes, many middle-aged greasy men in the team had to hide their faces and run away.
"According to the clues we have previously learned, Li Haidong made a deposit at the Jiqipo Branch of the Agricultural Bank of China a few hours before the incident, that is, on the afternoon of the 20th. The bank video also confirmed that it was Li Haidong himself who made the deposit at that time, which means that Li Haidong himself There was nothing abnormal in the hours before the incident. In other words, Li Haidong should not have cleaned Building 17 before the incident, such as erasing fingerprints."
"However, we conducted three carpet checks in Building 17, including before and after the crime scene, and we did not find any fingerprint marks. And Li Haidong did not do any cleaning in Building 17, because we were in Building 17 A large number of fingerprints were extracted from the counterfeiting equipment and fake certificates. Leaders, please listen clearly. What I am talking about here are finger prints, not fingerprints."
Xiang Juan's eyes were bloodshot and she looked tired. She raised her voice after speaking. Following her statement, many fingerprints without fingerprints were quickly displayed on the projection screen in the conference room.
"Did Li Haidong smooth his fingerprints, destroy them in other ways, or wear nylon gloves?" Deputy Director Zhang stared at the screen and asked.
"According to various surveillance videos obtained by the information team, Li Haidong never wears any gloves other than a hat and a mask when traveling. Therefore, we also collected data from his car. Unfortunately, we only found finger prints. We finally found I also began to wonder if Li Haidong applied a layer of transparent nail polish on the inside of his fingers, or polished his fingerprints, or even destroyed his fingerprints through some extreme methods, such as burning, scalding, inserting his fingers into sulfuric acid, etc. . In this way, even if he leaves fingerprints in his daily life, he will not leave fingerprints. So I went to the hospital, only to find that Li Haidong was a person without fingerprints at all." Xiang Juan said.
Li Haidong jumped from the 13th floor, but he did not die. He is still lying in the hospital on a ventilator and has not woken up. The doctor said that he might become a vegetative state. Everyone here knows this.
According to relevant legal provisions, if the only criminal suspect dies, the case should be dismissed. Li Haidong is not dead, and the case itself has great influence and many doubts, so Bai Tuwen must file a case for investigation.
"Can you explain it more clearly, what is the situation without fingerprints?" Director Liu finally spoke. After listening to Ma Hongwen's report before, he could certainly smell that this case was by no means a simple murder and corpse dismemberment, and judging from the current situation, the complexity of this case had exceeded his expectations and imagination.
"Actually, it is a very rare disease called 'dermatoglyphism'. People with this disease are born without fingerprints and secrete less hand sweat. Apart from this, they will not have any other physical discomfort or abnormalities. . The doctor said that this disease is generally caused by genetic mutations, which means it is hereditary." Xiang Juan said.
At this time, what was displayed on the projection screen was a certificate issued by Li Haidong's hospital that Li Haidong suffered from dermatoglyphic disease. It was stamped with the official seal of "Yancheng Central Hospital", which was very conspicuous.
"In other words, the goal of confirming that Li Haidong is one of the Wang brothers through fingerprint comparison cannot be achieved? As for the toe prints, they are not entered in the household registration system?" Director Liu asked.
Xiang Juan nodded in agreement, and then elaborated on Director Liu's second question: "This is what I want to say next. After checking, Li Haidong's ID card was changed on April 8, 2011, and is valid for 20 In 2007, the issuing authority was the Yanshan Branch of the Yancheng Public Security Bureau. Since the newly revised "Resident Identity Card Law" had not been officially implemented at that time, whether citizens had to enter their fingerprints or toe prints when applying for or renewing their identity cards was mainly based on a voluntary principle. Therefore, Li Haidong’s identity information was not recorded in the public security household registration system with fingerprints or toe prints, and there was no record of whether he was disabled.”
The newly revised "Resident Identity Card Law" only came into effect on January 1, 2012, which clearly stipulates that citizens must register fingerprint information when applying to receive, replace, or renew their identity cards. There are also detailed regulations for cases where fingerprints cannot be entered: collect fingerprints from fingers with fingerprints and indicate fingers without fingerprints; if there are no fingerprints, such as missing upper limbs, toe prints can be collected; if fingerprints cannot be taken, all fingerprints cannot be taken , disability status can be noted and recorded. Li Haidong's ID card is still valid so far and has not been replaced, so no toe prints or related records have been entered.
Everyone stared at the front and back screenshots of Li Haidong’s identity information on the screen. These information are obtained from screenshots of inquiries in the household registration system, and are not Li Haidong's original identity documents.
Director Liu frowned and asked again: "Where are the ID numbers of the Wang brothers? They can't be compared with Li Haidong's ID numbers?"
Xiang Juan said with a wry smile: "Under normal circumstances, when a citizen's name changes, the household registration system will indicate the previous name in the name column, and the ID number will never change. However, we all underestimated Li Haidong and the deceased, or It’s said to be the ability of Wang’s mother and son.”
At this time, screenshots of the front and back sides of the ID cards of the Wang brothers and Li Haidong popped up on the projection screen. The front and back sides of each ID card were placed up and down, and the three ID cards were placed in a straight line.
"As you can see, Li Haidong's ID card numbers are inconsistent with those of the Wang brothers. The household registration addresses are different, but the dates of birth are the same, and the people in the ID photos also look exactly the same. The issuing authority for the Wang brothers' ID cards is The validity period of the Sanqing Branch of the Yancheng Public Security Bureau is also exactly the same, from April 15, 2011 to April 15, 2021, which is only 7 days different from the validity period of Li Haidong’s ID card. The identity information of the Wang brothers There is also a lack of fingerprint entry. According to the speculation and analysis of Comrade Li Zhudao of the field team, it is very likely that Li Haidong, or the Wang brothers, have two ID cards with completely different ID numbers and names. This is also what the comrades of the information team have been querying. When looking for the identity information of Li Haidong and the Wang brothers, we never discovered the reason why they used their previous names."
