The DNA similarity between the suspect Li Haidong and the deceased reached 99.99%, which is a mother-child relationship. The results of the technical team's appraisal came out the next day. Although everyone had been mentally prepared, they were still shocked by this result and were speechless.

What kind of grudge and grudge can cause such a human tragedy between mother and son? This is a question hanging in the minds of all the members of the task force, but no one has asked a single word.

Great compassion is silent. Asking anything, saying anything is superfluous.

The weather seemed to be getting cooler all of a sudden, and everyone suddenly felt a little colder in the air.

"Is Li Haidong Wang An or Wang Kang? We don't know for the time being, so let's call it Li Haidong for the time being. In the conference room, Li Zhudao was reporting on the investigation.

Present at the meeting today were not only the head of the Ma detachment, but also the top leaders of the city bureau and several deputy directors. The nature of the white soil copywriting is already bad and the impact is extremely bad, coupled with the mother-son relationship between the suspect and the deceased that the head of the Ma detachment suddenly reported to the city bureau, which made Director Liu Jinsong, who was giving orders behind the scenes, unable to sit still any longer. This criminal case not only tramples on the bottom line of the law, but also tramples on the bottom line of morality, ethics, public order and good customs. Director Liu issued a gag order as soon as possible, strictly ordering that there should be no mistakes in the secrecy work, and whoever leaked the news would be asked. The overwhelming public opinion has already made him anxious, and the pressure from the provincial and municipal leaders has overwhelmed him, and before the case is really solved, this kind of extremely impactful negative news will only add fuel to the fire and make it worse for public opinion once it is leaked. Whether it was due to work needs or the complexity and severity of the case, he felt that it was necessary to command from the front and listen to the work reports of the front-line case-handling personnel.

After Li Zhudao reported on the previous work and the doubts in the case itself, he began to state 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, except for 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?" Zhang Xiao, who is in charge of criminal investigation, and Deputy Director Zhang asked.

"The face and fingers of the deceased were destroyed, as were all documents related to identity information, and no fingerprints could be extracted from room 1304. That is, proceeding only from the body of the deceased, we cannot prove her identity. The technical team also did not extract any hair clues from Building 17 of Harmony Community, and we wanted to prove that the deceased was the owner of Building 17 of Harmony Community through DNA comparison verification, but we could not achieve it. And between Li Haidong and the Wang brothers, except for the ID card photo is exactly the same, there is no other strong evidence to prove that Li Haidong is one of the Wang brothers, and there is no other clue evidence for us to distinguish whether he is Wang An or Wang Kang. Li Zhudao said.

"This ...... Can Li Haidong really erase all traces? Deputy Director Zhang's tone was full of doubt. Wherever you walk by, you will leave traces, and no matter what kind of contact human beings have made, they will definitely leave traces. This is almost the cornerstone of modern forensic science. The subtext of Deputy Director Zhang is that he believes that there were any omissions in the investigation process of the case-handling personnel. After all, even computer machines sometimes go wrong, let alone people.

Deputy Director Zhang's words made some comrades of the task force more or less unhappy on their faces. Everyone is so busy that their feet don't touch the ground, they haven't slept well for two consecutive days and nights, and they don't even have time to poop, and now they are still questioned about not being meticulous and serious enough, and anyone will feel uncomfortable. Especially Xiao Wang, after hearing this, he looked like his nostrils were facing the sky, but fortunately he was not good enough, sitting in the back row, and no one noticed.

"Technical group, to the team leader, you report to the bureau leader about the technical identification work." The detachment leader Ma Hongwen was expressionless, and he couldn't see any emotional changes, so he directly responded to it.

The head of the technical team is Xiang Juan. Xiang Group Leader had been a "Yellow Critic" before, and when he opened his mouth to tell a joke, many middle-aged greasy men in the team had to hide their faces and run away.

"According to the clues we have before, Li Haidong was still depositing money at the Qipo branch of the Agricultural Bank of China a few hours before the crime, that is, on the afternoon of the 20th, and it was confirmed through the bank video that it was Li Haidong himself who deposited the money at that time, which means that Li Haidong did not have any abnormalities in the hours before the incident. In other words, Li Haidong should not have wiped his fingerprints on Building 17 before the crime. ”

"However, we conducted three carpet checks in Building 17, including before and after the crime scene, and did not find any fingerprints. And Li Haidong did not do any cleaning of Building 17, because we extracted a large number of finger prints from the counterfeiting equipment and fake certificates in Building 17. Leaders, please listen clearly, I am talking about fingerprints, not fingerprints. ”

Xiang Juan's eyes were bloodshot, her face was tired, and she deliberately raised her voice later. With her statement, many fingerprints without fingerprints were soon displayed on the projection screen in the conference room.

"Did Li Haidong smooth out his fingerprints, or destroyed them by other means, or did he wear nylon gloves or something?" Deputy Director Zhang stared at the projection screen and asked.

According to various surveillance videos retrieved by the information group, Li Haidong never wore any gloves except for hats and masks. So, we also collected it in his car, and unfortunately, we only found finger prints. At first, we also wondered if Li Haidong had applied a layer of transparent nail polish to the inside of his fingers, or smoothed out his fingerprints, or even destroyed his fingerprints in some extreme ways, such as burns, scalds, and inserting sulfuric acid into his fingers. In this way, even if he leaves finger prints in his daily life, he will not leave fingerprint prints. So I went to the hospital, but it turned out 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, and is still lying on a ventilator in the hospital and has not woken up. Doctors said there was a risk of turning into a vegetative state. Everyone here knows that.

In accordance with the relevant laws and regulations, where the only criminal suspect is deceased, the case shall be withdrawn. Li Haidong is not dead, and the case itself has a great impact and many suspicious points, so the Baitu case must be filed and investigated.

"Tell me more clearly, what is the situation without fingerprints?" Director Liu finally spoke. Listening to Ma Hongwen's report before, of course, he could also sniff out that this case was by no means a simple murder and dismemberment, and only from the current point of view, the complexity of this case has exceeded his estimate and imagination.

"In fact, it is a very rare disease called 'dermatosis', and people with this disease are born without fingerprints and secrete less sweaty hands. Other than that, there will be no other discomfort or abnormalities in the body. Doctors say the disease is usually caused by a genetic mutation, which means it is hereditary. Xiang Juan said.

At this time, what was displayed on the screen was a certificate issued by Li Haidong's hospital that Li Haidong suffered from dermatosis disease, which was stamped with the official seal of "Yancheng Central Hospital", which was very conspicuous.

In other words, if you want to compare fingerprints, you can't achieve the goal of confirming that Li Haidong is one of the Wang brothers? What about toe lines, which are not entered in the household registration system? Director Liu asked.

Xiang Juan nodded yes, and then explained Liu Ju's second question: "This is also what I want to say next." Li Haidong's ID card, after investigation, was replaced on April 8, 2011, valid for 20 years, and issued by the Yanshan Branch of the Yancheng Public Security Bureau. Since the newly revised Resident Identity Card Law had not yet been formally implemented at that time, whether or not citizens entered fingerprints or toe prints when applying for and renewing their identity cards was mainly voluntary. Therefore, Li Haidong's identity information was not entered into 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, which only came into effect on 1 January 2012, clearly stipulates that citizens must register fingerprint information when applying to receive, renew or replace their identity cards. There are also detailed regulations for the situation that fingerprints cannot be entered: collect the fingerprints of fingers with fingerprints, and indicate fingers without fingerprints; All fingerprints that are absent, such as those with missing upper limbs, can be collected for toe prints; Where all fingerprints cannot be taken, the disability status may be noted and recorded. Li Haidong's ID card is still valid so far, and he has not been renewed, so he has not entered his toe prints or explained the relevant records.

Everyone stared at the screenshots of the front and back of Li Haidong's identity information on the screen. These materials are all taken from the screenshots of the household registration system, and are not Li Haidong's original identity documents.

Director Liu frowned, and asked again: "What about the ID number of the Wang brothers, and it can't be compared with Li Haidong's ID number?" ”

Xiang Juan said with a wry smile: "Under normal circumstances, when a citizen's name is changed, the household registration system will indicate the former name in the name column, and the ID number will never change. However, we all underestimated the ability of Li Haidong and the deceased, or rather the mother and son of the Wang family. ”

At this time, screenshots of the front and back of the Wang brothers and Li Haidong's ID cards jumped out on the projection screen, and the front and back of each ID card were placed up and down, and the three ID cards were placed in a straight line.

"You can see that Li Haidong's ID number is inconsistent with the ID number of the Wang brothers, the household registration address is different, but the date of birth is the same, and the people on the ID photo also look exactly the same. The issuing authority of the Wang brothers' ID card is the Sanqing Branch of the Yancheng Public Security Bureau, and its validity period is exactly the same, from April 15, 2011 to April 15, 2021, which is only 7 days before and after the validity period of Li Haidong's ID card. The identity information of the Wang brothers also lacked fingerprints. According to the conjecture and analysis of Comrade Li Zhudao of the field service group, it is very likely that Li Haidong, or the Wang brothers, had two ID cards with completely different ID numbers and names. This is also the reason why the comrades of the information group did not find out that Li Haidong and the Wang brothers had used their names when they inquired about their identity information. ”
