[Xiao Mo is back to update~ Guys! ] 】

Because the area is relatively not so large, it is still more time-saving to inspect, and the colleagues of the criminal technique were busy as soon as they entered the door, and He Ning and Tang Li couldn't help much, so they simply observed the situation inside the house without getting in the way, and saw if there was anything more abnormal.

Lu Kangsheng's residence looks a little messy, there are not many things in the living room, there is only a double fabric sofa, a small coffee table with a simple style, there is a small garbage basket next to the coffee table, but the small garbage basket is on the ground, and some of the garbage and debris in it are scattered, the small coffee table and the fabric sofa are not parallel positions, but form an unnatural angle, at least normal people will never put the sofa and coffee table in that way, It looks like the coffee table has hit the sofa, and if it weren't for the back of the sofa already leaning against the wall, I'm afraid it wouldn't have been placed in such a regular place.

"Is it possible that there was a fight here?" After observing it, Henin asked Tonic Li.

"I can't rule out this possibility, otherwise the downstairs neighbors wouldn't have that kind of feedback." Although Tonic couldn't stand the noise of the old lady downstairs and the character of chewing his tongue, he still didn't doubt the old lady about it, after all, there was no point in lying about this kind of thing, not to mention that he had quietly noticed it when he was in the old lady's house, because it was an old house, the wall was still that old-fashioned stucco wall, and the ceiling was no exception. It's not big, it's roughly round, and it looks like the kind of mark left by the mop rod when it hits the ceiling, so what the old lady said should be true.

"Then let's see if the colleagues of the criminal technology can find anything!" Since He Ning took over this case, she has always been calm, but now, she is a little less calm, no matter from which angle to analyze, Lu Kangsheng is the most likely to be killed, the most in line with the identity of the victim, if you can't find valuable clues from here, then in addition to the clues in this case, He Ning himself will feel a little confused, and don't know how to sort out his own investigation ideas.

Tonic actually had the same idea, but he seemed a little more calm than He Ning, and if he was nervous or worried, he thought about it silently in his heart and would not show it.

After a while, the colleagues of the criminal technology really brought them a good news, a small amount of blood stains were found in the living room, although the surface was wiped with the naked eye at all, but they could not hide the reagents they used, and then, according to the location of the wiped blood stains, they found a small amount of residual blood stains from the cracks in the floor, carefully extracted them with cotton swabs, and prepared to take them back for blood type testing and DNA sample extraction, which was used as important evidence to determine the identity of the injured.

The colleagues of the criminal technology also found that there had indeed been a fight in this house, there were traces of shoe soles being dragged on the ground, and there were also some inconspicuous small marks on the wall.

Soon this speculation was confirmed, they found a broken umbrella handle under the sofa, it looks like it should belong to the kind of long-handled umbrella that is folded, the criminal staff compared the traces on the wall, and determined that the mark was smashed out of this plastic handle, and the force of the smashing out should not be small, so the umbrella handle hit the wall and then broke off and fell behind the sofa.

Being able to hit a long umbrella on the wall and cause the handle to break on the spot is not small at all, and it is conceivable that the scene at that time should definitely not be an ordinary fight.

In addition to this broken umbrella handle, the handle on the bedroom door in Lu Kangsheng's residence was also broken, and the damage was caused by the vigorous pulling that caused the screw used to fix the handle to fall out directly from the door, because only one side was loose, so the damaged doorknob still hung on the door.

According to the series of traces found in Lu Kangsheng's house, the colleagues of criminal technology carried out a rough restoration, because the scene was carefully cleaned, so no more specific trace clues could be found, and this restoration was only a rough judgment, which could not be 100% accurate. They thought that there should have been a fight in the house at that time, one of them should have wanted to force the other person to leave with him, or to expel the other party from his house, the other party insisted on refusing, the two people pulled and fought, one side dragged the other party, and the other party relied on the center of gravity downward to try to stop the other party's move, and the shoes rubbed on the floor in the process of dragging and pulling, and the one who was dragged was very likely to avoid the other party's success. I've been trying to hold on to everything I can hold, so I pulled the doorknob out of the way in the process of struggling.

According to the clues provided by the old lady downstairs, the upstairs suddenly quieted down, and no one has seen Lu Kangsheng since then, and the old lady of the neighborhood has never heard any movement upstairs These details, it can basically be inferred that the grappling that night should be the uninvited guest who came to take Lu Kangsheng away, but Lu Kangsheng insisted on refusing, and the final result was obvious, Lu Kangsheng was still taken away. Combined with the traces on the wall, the broken umbrella handle, etc., everyone suspected that Lu Kangsheng was unconscious when he finally followed the other party away, which means that the other party may have succeeded in the attack, and then Lu Kangsheng bled after being attacked and lost consciousness, and after the attacker cleaned the scene, he left with Lu Kangsheng, as for where he went afterward, this is not the few trace evidence at the scene that can provide.

Of course, there is another possibility, that is, Lu Kangsheng was struggling to expel the uninvited guests who came to the door, and the two of them fought, and in the process of fighting, Lu Kangsheng injured each other, so he cleaned up the house and hid out in order to avoid legal prosecution, and he has not been found yet.

In the end, the blood sample taken from the house becomes particularly important.

"Judging from the original distribution of blood stains at the scene, is the person who bleed seriously injured?" He Ning asked.

"It's okay, it's not serious, at least it's definitely not a fatal injury, unless the deceased died of poisoning, if it's a traumatic injury, that little bit of blood, horizontal and vertical, can't kill anyone." Although the colleague of criminal technology said that he was not a forensic professional, after all, he had been engaged in this business for some days, and he still had a lot of experience in judging the way the deceased was attacked according to the shape and location of the bloodstains, so he could directly answer He Ning's question, "According to my work experience, the blood stains on the ground should have flowed out after the deceased fell to the ground, so the area is not large, but it is enough to penetrate into the cracks in the floor, and the wound should not be a very shallow epidermal injury." ”

He Ning was silent, she thought about it, on such a night, because the community is relatively old, there is no monitoring equipment installed, let alone closed management, the season at that time is when the sky is relatively cold, if there is another person with a coat covering his face, walking staggeringly, walking out of the building, it is estimated that even if he is seen, he will be regarded as a drunk drunk, which may not cause any suspicion, not to mention that this matter has been half a year long, After such a long time, it will be difficult to find witnesses. Therefore, the top priority at the moment is to take the blood sample and determine whether the injured person is Lu Kangsheng or someone else, so as to determine what kind of development direction will be the next thing.

It is not difficult to extract a blood sample to get a result, what is really more difficult is how to determine whether it is Lu Kangsheng's own bloodstains, after all, Lu Kangsheng is now alive and dead, and ordinary people can't be idle and have nothing to do, save a little blood sample or something in their own home, and keep it for the police to use to determine their identity once something happens, plus Lu Kangsheng is the kind of person who doesn't have any bad records and criminal records. So there is no record related to him in the fingerprint database and DNA database, which makes it a little difficult for He Ning and Tang Li, and they spent a lot of time to understand the situation, Lu Kangsheng has always had the habit of donating blood regularly, but he himself has been missing for more than half a year, when He Ning and Tang Li went to the local blood station to understand the situation, with the assistance of the other party's staff, they learned that Lu Kangsheng's original blood donation had already been put into the hospital's clinical treatment. The only thing that the blood bank can provide is Lu Kangsheng's blood group information.

If Lu Kangsheng is the legendary panda blood, then maybe this matter will be easier to do, but the answer from the blood station is that Lu Kangsheng belongs to type O blood, that is, the blood type with the largest population at present, due to the large number of people with type O blood, aside from DNA information, it is difficult to determine that Lu Kangsheng himself was injured in the house that day just by having the same blood type. In the end, there was no other way, He Ning and Tang Li had to choose to contact Lu Kangsheng's parents through Dapeng, the two old people had been exhausted by the divorce of Lu Kangsheng before, and now when they heard that their son was missing, the police wanted them to provide DNA samples to help find their son's traces, and naturally received another stimulation, but in the end they still came to the Public Security Bureau and cooperated with He Ning and their work, He Ning looked at the two old men who were old and emaciated and still looked haggard, I also feel very bad in my heart.

After a few days of overtime, the DNA comparison results of Lu Kangsheng's parents and the bloodstains in the house came out, and the kinship between them can be determined, and it is very certain that they belong to the mother and son/father and son, so that is to say, the residual bloodstains found in Lu Kangsheng's residence are indeed from Lu Kangsheng himself, and the person who was finally defeated and injured in that fight that day was Lu Kangsheng himself, and Lu Kangsheng has been completely missing since then.

Whether this news is good news or bad news depends on who it is for, for Tang Li and He Ning, this is undoubtedly good news, Ye Maocai, who directly bought Miao Yuan and Lin Rongde's corpses, can be related to Bu Zhiqiang, and Bu Zhiqiang has such a relationship between Bu Zhiqiang and Lu Kangsheng, and now the three of them are missing, Lu Kangsheng is the male deceased who replaced Yin Houlu and was cremated, this possibility is getting bigger and bigger, and the context of the case has been further clarified.

However, this incident is not good news for Lu Kangsheng's parents, just because a girlfriend when he was a student, a good home for his son and daughter-in-law was simply broken up, and his grandson was taken away by his daughter-in-law, and he has never seen each other, which has always been the biggest pain in their hearts for the two old people, and when the public security bureau took DNA samples, they couldn't help but cry to He Ning and Tang Li, and now they have to face the news that their son may have been killed and is no longer alive. This is definitely a bolt from the blue for them, so in the end, whether to tell them frankly as soon as possible, He Ning and Tang Li are very hesitant, after all, even if it is 90% certain, there are still 10% variables, and the bodies of these two old men are obviously unable to withstand such a big blow, in case they hear such news, the two old men can't stand the danger of their lives all of a sudden, and even their lives are whimpering, In the end, Lu Kangsheng was not the unidentified deceased in this case, so the adverse effects of this incident are not only very costly, but also irreversible.

So He Ning reported the matter to the captain Yang Cheng and asked him to help make a decision. Although the statement is not merciful, discipline must be put first in the work, but in the face of this non-principled problem, Yang Cheng also needs to consider this problem from the perspective of human feelings, after careful consideration, he decided to let He Ning and Tang Li notify Dapeng of such a result first, and Lu Kangsheng's parents will keep it secret for the time being, and wait until there is more definite evidence, and then Dapeng will decide whether to infiltrate them euphemistically, or help hide it all the time, after all, Lu Kangsheng was more abnormal before, once entrusted to Da Peng, if something really happened to him, his parents were taken care of by Da Peng, then this matter should be considered by Da Peng.
