Chapter 30

With the closing of the door and curtains, the room quickly darkened. After everyone's eyes gradually adapted to the darkness, Sun Mingrui picked up the watering can and walked to the bedside to start spraying. After a while, the indoor bed, walls, and bedside There are many traces of blue light on the table and on the ground beside the bed.

Lin Huan stood at the door and asked, "Is this bleach or blood?"

"Blood stains." Sun Mingrui explained, "Our blue light reagent is not affected by bleach. The luminol reaction relies on the iron in hemoglobin to catalyze the decomposition of hydrogen peroxide, turning dioxygen into single oxygen, thereby oxidizing luminol Produces blue light. But chlorine ions in bleach can also catalyze hydrogen peroxide, so in the early years, only by the length and flickering state of blue light and other auxiliary technologies to distinguish between bleach and blood. Now with this blue light reagent, Not only do you no longer need long-exposure photos to fix the scene, but you can also avoid the effects of bleaching agents such as hypochlorous acid on the blood. What you show with blue light reagents is blood stains, and there is no other interference.”

Lin Huan nodded: "With the development of the Internet, good and bad things can be known quickly. Now everyone knows how to wear gloves when committing crimes, and even learned to use disinfectant to clean up the scene."

Sun Mingrui answered: "They are making progress, and we are not idle. What's more, all the technologies that can be found on the Internet are about five years behind. The real front-end technology is only in the hands of our professionals."

Su Xing looked at Sun Mingrui's eloquent and eloquent appearance, and somehow thought of those male peacocks who opened their tails in courtship.He smiled silently, and after Guo Junjie finished taking pictures, he walked around the bed to observe the blue lights.

"I found something!" Sun Mingrui pointed to the blue light on the ground near the door and said, "At least two people!"

Lin Huan: "How did you tell?"

Sun Mingrui: "There are blood stains. Simply put, the blood of the deceased was splashed on the murderer's body instead of the ground, so there is no trace left where the blood stains should be. Captain Yan, come here."

Yan Lan walked up to Sun Mingrui, followed Sun Mingrui's instructions and stood on the left side of the door, while Lin Huan stood on the right side of the door.Sun Mingrui said, "Look at your feet."

Lin Huan looked down and saw blue lights dotted around where he was standing.

Sun Mingrui continued, "Take a step back."

Lin Huan did as he did, and then suddenly realized: "I see! There should be blood here!"

Sun Mingrui analyzed: "Although according to Dui Yan's height and long legs, it is true that he can step on these two marks by himself, but it is impossible for him to make the toes of both feet point inward. These are the marks left by the two toes. And size analysis may be men's leather shoes. It's a pity that there are no complete shoe prints, otherwise I can give a more accurate conclusion."

"Brother Rui, come here." Su Xing stood by the bed and said, "I can barely reach this photo frame with my height, and the height of this bed is lower than sister Huan's knee height, and people who are taller than sister Huan kneel on the bed Instead, it will be shorter, no matter whether the murderer wipes or takes down the photo frame to clean it, he has to stand on the bed. Brother Rui, see if you can extract the footprints of wearing socks."

"Little Su, why are you so powerful!" Lin Huan walked to the bed and gestured, "Those who are shorter than me may not be able to reach that photo frame standing on the bed."

Sun Mingrui scanned the bed carefully with a footprint search light, then shook his head: "The whole bed has been cleaned, the murderer is very cautious, there is no bloody footprint left in the house, I suspect the murderer entered the room wearing shoe covers. Otherwise, according to the amount of bleeding, it is impossible to leave no trace."

"This murderer is really a thief." Lin Huan looked at Su Xing and Sun Mingrui a little discouraged, "So the two experts, is there any evidence to provide?"

"This should be the first scene." Su Xing put his hand in and analyzed, "Judging from the occult blood traces, the murderer smashed the deceased to death on the bed, and then dismembered the body. It probably divided... 11 yuan."

"Can you see that too?" Lin Huan asked in surprise.

Su Xing pointed to the bed and said: "The head counts as one piece. There are blood splatters on the left side about 175 centimeters and [-] centimeters down, and there are more bloodstains on the bed. We just found a left arm without a hand. , the length is just about the same. The two bloodstains on the right side are slightly higher than the left side, presumably they should be cut off from the shoulder joint, elbow joint and wrist joint. Looking down, there are more bloodstains in the middle of the bed, this place It is almost the sacroiliac joint position of a person with a height of about [-]..."

Lin Huan: "What joint?"

"It's the position of the pelvis." Su Xing continued, "Further down is the position of the knee joint. So it means that the murderer cut off the head of the corpse and kept it in the house, and the remaining body part, the right arm, was cut into three sections , the legs were cut into four pieces, plus the torso, left hand and the left arm we just found, a total of 11 yuan."

Yan Lan asked, "Can you guess what tool it is?"

Su Xing: "Judging from the cut surface and throwing blood, it should be holding a chainsaw."

Lin Huan said from the side: "My God! Baby, you are so amazing! You can analyze so much of a single bloodstain!"

"What else do you think?" Yan Lan asked.

Su Xing thought for a while and said: "I think what Liu Qingyuan said just now is very reasonable. The murderer may have left the arm with needles there on purpose. If the murderer really cut the body according to the way I speculated, Then he probably considers it from the two aspects of easy cutting and easy carrying, but the arm we found starts from 1/3 of the arm to the wrist, and there is an elbow joint in the middle, which does not meet the requirements. His habit of cutting other parts of the body is most likely due to his need to leave the mark on the dead man's arm. Of course, this assumes that the cutting method I speculate is correct."

Sun Mingrui nodded and said: "I also think what Xiao Su said is right. These bloodstains are very characteristic. The bloodstains in the house should be analyzed almost. Open the door, I'm about to die of suffocation."

Yan Lan opened the door and window, Sun Mingrui tugged at the survey suit and said, "I'm going out to catch my breath, you guys go ahead, call me if you need anything."

Lin Huan walked to the long table to the east and stood still. Yan Lan asked, "What did you find?"

Lin Huan said, "This kitchen lacks things."

Yan Lan: "Aren't there pots and pans here?"

Su Xing's voice came from behind: "There is no water."

"Yes!" Lin Huan turned around and gave Su Xing a thumbs up, "Little Su baby is awesome today! Boss! I want to empathize with you!"

"Move it, you don't need to notify me." Yan Lan added, "Make it clear before moving it."

Lin Huan pointed to the items on the long table and said: "There is still 1/3 of the cooking oil left. Light soy sauce, dark soy sauce, cooking wine, and mature vinegar all have traces of use, which proves that the owner has the habit of cooking. There is no sink, so where does he wash pots, dishes, and vegetables? There is a self-drilling well in the yard, but there is no tap beside the well, and the ground in the corner of the house is obviously smoother than the one next to it. This is cement Due to the characteristics of the ground, the place that has been soaked in water for a long time will become smooth and shiny. So I guess the owner usually uses a bucket to catch water and put it in the house. So the question is, what about the bucket?"

Yan Lan rushed out and shouted, "Qiao Chen! Go ask Meng Jianguang if he has a bucket in his room!"

"it is good----"

After a while, Qiao Chen walked into the room and said, "There is indeed one. He said it was a large white plastic bucket under the kitchen window. Also, I just confirmed that Meng Jianguang has no time to commit crimes. He lives at a friend’s house, and there are certificates. Also, he doesn’t have disinfectant or chainsaws at home.”

"Has he calmed down?" Yan Lan asked.

Qiao Chen nodded: "It's almost there, should I ask here or take it home?"

"Take it back!" Lin Huan suddenly shouted, "Boss, come quickly!"

"I'm not deaf, please keep your voice down," Yan Lan said as he walked to Lin Huan's side.

From the corner behind the refrigerator, Lin Huan lifted two bottles with straws inserted in front of Yan Lan. Yan Lan immediately took out the evidence bag and asked Lin Huan to put the bottles in.

Yan Lan handed the evidence bag to Qiao Chen and said, "Call Yu Sen and tell him to end his vacation immediately!"

"it is good."

Lin Huan gloated and said, "Lao Yu's once-in-a-decade vacation has come to naught again."

"What's he thinking about vacation at this time?!" Yan Lan complained, and when he was about to turn around, he accidentally glanced at the closet next to him. Observe Su Xing through the mirror on the top.Sure enough, the feeling of being on his back was not because he was at the scene of the crime, but because Su Xing had been watching him silently from behind.It took Yan Lan five seconds to confirm that the narcissistic gene in his body did not "lie about the military situation" inappropriately, so he clearly realized that he had won the lottery.

When he didn't have a case in these few days, he just confirmed that he really had some meaning for Su Xing, not because he sympathized with the death of his parents, nor because he felt sorry for his poor health, but because he really had a good impression of this person.In fact, Yan Lan hadn't figured out how to deal with this problem yet, but now he suddenly found that Su Xing felt the same way about him, which made him feel a little overwhelmed for a moment.The conversation between Qiao Chen and Lin Huan was next to his ears, but Yan Lan didn't listen to a word. He calmed down, and when he looked again, Su Xing had already lowered his head.

Yan Lan turned around and asked, "Su Xing, what are you thinking?"

Su Xing raised his head and looked directly at Yan Lan, his eyes were as calm and peaceful as the sea surface when there was no wind, as if the eyes just now were Yan Lan's illusion.After a while, Su Xing said, "I guess the murderer identified the wrong person."

Yan Lan's agitated heart hung in his chest with no place to rest, so he could only use his instinct to deal with it: "Be more specific."

Su Xing's right hand was pointing unconsciously on his left arm, which seemed to be his habit when he was thinking, and he only heard him say: "Although the means of death has not yet been determined, it is not like taking local materials from the perspective of traces and behavioral logic. The murderer prepared the killing tools, body dissection tools and cleaning tools in advance, and he must have come prepared, which basically ruled out the possibility of passionate murder, so there is a high probability that the murderer knew the deceased. Even the most insane murderer, in the When committing crimes, they would choose an environment as safe and familiar as possible. Ordinary killers are afraid of being discovered, while many perverted killers do not want to be disturbed. Few people are crazy enough to go to other people's homes to kill and dismember their bodies. But now an unidentified deceased was killed and dismembered in Meng Jianguang's house. I think either the murderer knew that the original resident would not appear for a certain period of time, or the murderer thought that the person he killed was the actual occupant of the house Just now I saw that Meng Jianguang was riding a food delivery car. He should be a delivery man. He has a lot of freedom in his working hours. No one can be sure that he will not be at home for a certain period of time. Then only Another possibility is that the murderer thought it was Meng Jianguang who was killed. Of course, there is another extreme situation, the murderer is a lunatic and cannot be deduced according to common sense."

Lin Huan blinked and said, "Baby, come to criminal investigation! Criminal investigation needs you!"

Yan Lan regained his composure after Su Xing opened his mouth to analyze. He slightly raised his hand and said to Lin Huan: "Don't interrupt him, let him continue talking."

Su Xing thought for a while and continued: "The fat brother said just now that it takes a deep hatred to smash the dead like this. At first, I also thought it might be seeking revenge, but later I felt that it was not right, because if it is really revenge killing Will not recognize the wrong person. There is also the method of dismembering the corpse. If a person really hates another person to the extent of dismembering the corpse, then he will not dismember the corpse like this. The most vicious dismembering demons usually kill the victim The murderer’s method of dismembering the dead body, if only to vent his anger, is a bit ‘kind’. I mean from the murderer’s point of view, don’t get me wrong.”

Qiao Chen nodded.

Su Xing went on to say: "Oh yes, there is another possibility that the deceased and the murderer were originally together, but for some reason they had a dispute, so they killed the deceased. But this goes back to the original question, they If something is prepared, it is unlikely to be a murder of passion, so their target is still Meng Jianguang."

Qiao Chen walked up to Su Xing, patted him on the shoulder, and said sadly: "Why are you a forensic doctor! You are still Wang Lao's apprentice! There is no way to dig this corner!"

Yan Lan took Qiao Chen's hand away from Su Xing's shoulder and said, "You should be thankful that he is Wang Lao's apprentice. He used the salary of the criminal department to provide us with ideas for criminal investigation. Is he still using poaching? There are no walls."

"Yes, yes, yes!" Lin Huan echoed, "We still took advantage!"

Su Xing lowered his head and smiled slightly, and said, "Don't be like this, I'm just thinking about it, it would be bad if I mislead you."

"Any investigation direction can't be missed, and we can't get it right just once." Yan Lan stared at Su Xing and said, "But now you have more important things to analyze."

"what?"

"Where will the rest of the body be?"

Su Xing was silent for a moment, then hesitantly said: "I think it's nearby, this time there is no basis, it's pure intuition."

Qiao Chen was a little discouraged, he looked at Yan Lan unrequitedly, and said, "I'll invite the police dog team..."

The reason why Qiao Chen reacted this way is because the police dog team of the Municipal Bureau, from the dog trainers to the police dogs, are all "generational meritorious service". ——Brush your face.

Qiao Chen's father is a veterinarian who runs a small pet hospital in the city.Naturally, these police dogs will not go to private pet hospitals for treatment and examination, but the dog trainers of the police dog team more or less have pets at home.After learning about Old Qiao's occupation, a tacit understanding was reached between them.Once the police dog team is invited for criminal investigation, Lao Qiao's pet hospital will receive the "family" of the dog trainer for free once.

Although everyone will pay in the end, Lao Qiao always offers discounts and free cat and dog food every time.The money became more and more unclear, and finally Qiao Chen gave up, went home and said to his father: "In the future, the things sent out will be accounted for, and my son will reimburse you!"

Old Qiao cheerfully took out an account book from the drawer and said, "I'll keep it all in your memory! I originally thought that it would be deducted from your marriage share in the future, but I don't know how long you will have to wait for your marriage. Now that you have mentioned , why not report now."

Qiao Chen belatedly realized that he had been slapped by his father, but after all the words had been said, he could only grit his teeth and accept the money.As a result, once, the criminal investigators didn't know what happened, and they called the police dog team seven times within a month.The shocking five-digit number on the bill that Old Qiao sent that month made Qiao Chen ready to eat instant noodles for three months. Later, Yan Lan threw him a contract and asked him to use this contract to take Old Qiao away. Coaxed to avoid the tens of thousands of accounts.

After so many years of relationship between Yan Lan and Qiao Chen, he naturally knew Qiao Chen's personality, and he would definitely not take the money if he gave it directly, so Yan Lan asked his cousin to find a high-end pet grooming shop and made a cooperation agreement. All the customers of that beauty shop would be referred to Old Qiao's clinic as long as they needed physical examinations, vaccines, or medical treatment.Every time Lao Qiao receives a customer, in addition to paying Lao Qiao consumables and medical expenses, the beauty shop will also give him 5% of the single consumption of the customer's membership card as a commission. , because rich people spend money on services, and the minimum credit card in that pet grooming shop is six figures.In this way, Old Qiao was making a steady profit without losing money, and Qiao Chen's debts were forgiven with a wave of his hand.Qiao Chen felt sorry all the time, and finally Yan Lan let go and asked Comrade Old Qiao to provide free life-long service for Yan Lingjin's two cats, so that this article was turned over.
