Evidence hunting forensic 4 unsolved case code

Everyone in the office of the unsolved case team was opening the windows, watching the grand scene of Luo Jianan chasing Ou Jian to fill the parking lot, and hearing Lin Dong's footsteps, they hurriedly returned to their places.It is necessary to combine work and rest, but during working hours, it is better not to scold the leader for nothing.

Lin Dong went into the room and saw the smiles on the faces of all the people in the group, and he simply shared what happened in the parking lot with everyone, and tears came out of He Lan's laughter.Rarely, Yang Kelin also showed a little smile, but his smile was not on the photo of Cao Yuan sent by Ou Jian to the liar, but on Lin Dong's "do not save him".

Before the laughter in the room died down, Lin Dong urged his life again: "What is Erfa chasing after?"

Tang Zhexue still had a smile on his lips: "I checked the individual business registration information of that noodle restaurant. Meng Jinsheng is the owner, and the person who signed the bill is Gao Ping, his wife. There is no real-name registration under Meng Jinsheng's name. I can't get in touch with the phone number for the time being, but Gao Ping got in touch, but they are divorced and haven't been in touch for several years."

"Meng Jinsheng is the second round?"

"No, he's almost fifty, and his age doesn't match."

"What about the second round? Does Gao Ping recognize him?"

"It is said that it may be Meng Jinsheng's nephew. His real name is Li Pengfa. He has been helping in their shop before, but then he went to Zhuhai to work, and he has not contacted him for more than ten years."

"Look for Meng Jinsheng first, he should have Li Pengfa's contact information."

"I asked Gao Ping to help me find out, and she said to send the news as soon as possible." Tang Zhexue reached out and took Lin Dong's cup, went to the water dispenser to fill it up, and put it on the desk, "What did Deng Mei's husband ask?" gone?"

After taking a sip of water to moisten his throat, Lin Dong relayed the inquiry to everyone.Tang Zhexue frowned after hearing this, and raised the same doubts as Lin Dong before: "Deng Mei can have children, why did she lie to her husband?"

He Lan tilted her head and thought for a while, then said, "She may be afraid that she will be arrested one day and bring disaster to the children."

"Well, what Lan Lan said makes sense." Tang Zhexue agreed, "It's women who understand women."

Lin Dong didn't comment, put down the water glass, and opened the original file.No matter how many times I look at the photos, those photos are still shocking: Among the three adult victims, the father and the eldest son were lying on the dining table. The autopsy records showed that there were no defensive injuries, which means that they were hacked without any defense at all; The son died on the threshold, with his head facing outwards and his feet facing inwards, indicating that he was chased before his death; bloodstains stretched from the main room to the bedroom on the east side, where Deng Mei's eight-month-old child was strangled in a deep sleep .

He looked at those photos over and over again, looking for unknown clues in them.Suddenly he noticed something, and stretched out his hand to the side: "Er Ji, give me the magnifying glass."

Tang Zhexue immediately opened the drawer and took out the magnifying glass, and threw it to the other party. At the same time, he stood up from his seat, walked around behind Lin Dong, and looked at the scene under the mirror—it was a bloodstain, and a spot that was neither dripping nor dripping. It was not a bloodstain that fell, nor was it splashed. The bloodstain was in a straight line with fuzzy edges, and the size was neither long nor short.Then Lin Dong turned back a few pages, turned to the photo of the murder weapon, stared at it for a few seconds, grabbed the handset of the landline and called Du Haiwei down.

Du Haiwei came here in response, looked at the bloodstain under the magnifying glass, and turned to look at Lin Dong: "You asked me to come to discuss how this bloodstain was formed?"

Lin Dong nodded in confirmation, and at the same time offered suggestions for reducing the difficulty: "I think the bloodstain here comes from the murder weapon, like someone put a machete on the ground, and the blood flowed down and seeped into the floor tiles."

Du Haiwei took a closer look with the magnifying glass and shook his head: "No, look, there are still some small splash-shaped blood droplets around here, it doesn't seem to be put down, but—"

He raised his arm and let go.

Next to him, Tang Zhexue caught the magnifying glass that fell from his hand and said dissatisfiedly, "Duke, we only have one magnifying glass left after falling, you can really destroy it."

"I know you can catch it, and you have good reflexes." Du Haiwei smiled gently, and Tang Zhexue couldn't help but turn to Lin Dong: "I'm going to do an experiment to see where the machete comes from." Falling from such a height can form exactly the same blood trail as in the photo."

As soon as he heard that the experiment was going to be done, Yue Lin was eager to move, wishing he could lift his ass and go with Du Haiwei.Lin Dong glanced at his ass that looked like it had grown nails, and said along the way: "Let Yue Lin help you."

"Yes! Team Lin!" Yue Lin jumped up, and dragged Yangkelin out from behind the three computer screens, "Let's go, Yangzi, let's go and learn together."

In the process of being dragged out of the office, Yang Kelin showed reluctance.

—

The experiment was carried out in the physical evidence room, where there is a special empty field for criminal technicians to use their imagination and verify the formation of certain traces and phenomena at the crime scene.There is also a small warehouse next to it, which houses various "murder weapons" of different textures, sizes and shapes.When Yue Lin saw Du Haiwei coming out of the warehouse with a machete imposingly, he somehow felt like watching Hong Kong movies when he was a child.

"Well, Mumu, come here."

Du Haiwei called Yue Lin to stand on the tarp and asked him to dip the machete into the artificial blood that Feng Ye brought.Yue Lin was taken aback by his address, thinking that Luo Jianan also called me Mumu before, why did they all follow Teacher Qi?

The size of the knife is almost the same as at the time of the crime, and the viscosity of artificial blood is close to that of human blood. As long as the movements are in place, the marks formed can highly fit the scene.Under Du Haiwei's signal, Yue Lin started throwing knives, squatting, standing, jumping, and running.Yang Kelin watched from the side, and felt that he was about to throw it away on his stomach.

After tossing around, Du Haiwei compared the remaining "bloodstains" with those at the scene of the crime in turn, and then chose the one thrown standing up, replaced it with a waterproof cloth, asked Yue Lin to bend his legs and lower his center of gravity, and then five centimeters five Centimeters up the height, and threw it four more times.Next, he compared the traces of these four experiments with the photos, and finally confirmed that the traces formed after the machete fell 85 to [-] centimeters from the ground were the closest to the ones in the photos.

Yue Lin didn't understand why he got the data, and he didn't answer when he asked, but just asked him to take the results back and pass them on to Lin Dong.As soon as I returned to the office and conveyed the results to Lin Dong, I saw the light flashing on Lin Dong's glasses, and patted the thick file on the table——

"There are two murderers in this murder case."

two?Originally, Yang Kelin was not interested in observing monkey-like experiments, but now he thinks it is a bit interesting.

Lin Dong didn't give a damn and explained: "Deng Mei's height is only 1.5 meters, so if the machete fell from her hand, it would not be more than [-] centimeters from the ground in an upright state. It takes a fall of [-] centimeters to form the same trace as in the photo."

"Wow, what's the difference?" Yue Lin compared the original photo with the photo taken by Du Haiwei's experiment, looked left and right, but didn't see much difference.

"It's so different in Du Ke's eyes. If you don't have that skill, don't read it." Yang Kelin took his mobile phone away from Yue Lin with a look of disgust—fingerprints were pinched on the screen. wipe.

"I don't just ask if I don't understand, and learn if I don't know it." Yue Lin flattened his mouth aggrieved.He knew that altitude would affect the form of blood dripping and splashing, but he didn't think that knowledge could be applied in this way.

——Hey, if Du Ke is the leader of forensics, he is far behind.

At this time, Tang Zhexue raised his hand and gestured for height, and said, "Then the murderer must be at least 1.7 meters tall."

Lin Dong opened the autopsy report and pointed to one of the data - among the three adult victims, only the youngest son was taller than 1.7 meters.

"The youngest son died outside the dinner table, so my idea is that both the father and the eldest brother were hacked to death by the younger brother, and then he regretted it, threw the knife, and wanted to surrender, but in the end..." Lin Dong stood up and walked away. Arriving at the back of Tang Zhexue, he raised his hand and gestured, "Deng Mei, who was behind the oriole, slashed on the neck."

After he finished speaking, there was silence in the room.Based on the available evidence, the logic holds, but what about the motivation?If it is said that Deng Mei hates this family and ruined the family, it is still excusable, so why did the younger brother cut off his own father and elder brother?

"Could it be..." Tang Zhexue muttered to himself, and then turned his gaze to Lin Dong, with mixed emotions in his eyes, "Out of jealousy? Jealous that father only bought a wife for his brother, but not himself? Without them, will Deng Mei belong to herself?"

"I think it may be worse than this, wait a minute."

Lin Dong called Qi Ming again and frowned slightly as he spoke.Putting down the phone, he said in a solemn tone: "The DNA test confirmed that the child is not the elder brother's, but the father's... Therefore, Deng Mei was bought back, not to be the eldest brother's wife alone, but to be a bachelor in their family. of……"

He didn't say the next word, but everyone in the room knew what it meant.No wonder Dunmeken pleaded guilty but refused to confess. A woman of her age might never admit to death that she had experienced such unbearable treatment.

"Lan Lan, are you okay?" Lin Dong asked suddenly, and he noticed that He Lan's expression was not right.

He Lan raised his head abruptly, then shook his head hastily.She was the only woman present, and she could understand Deng Mei's hatred, helplessness and grievance better than anyone else.It was her professionalism that allowed her to force herself to remain calm, and she analyzed clearly: "We are both victims, so my brother's behavior was interpreted as fleeing the scene, and the blood on his body, due to the lack of DNA identification technology at the time, could not tell who it was. The investigators intuitively believed that it was his blood, thus ignoring the presence of a second murderer at the scene."

Showing a look of approval, Lin Dong affirmed: "It should be like this, Yingjie, sort out the content, make an outline of the interrogation, call Fu Manjun and the others, and follow me to interrogate Deng Mei in half an hour."

After he finished arranging work, Tang Zhexue signaled to go out for a cigarette.

After lighting a cigarette, Tang Zhexue said worriedly: "Deng Mei is almost sixty, you are not afraid that something will happen to her if you tear her wound like this?"

"Then what to do, kill for life."

As the smoke drifted away, Lin Dong sighed helplessly: "I know this is unfair, but the law is so ruthless, if she had surrendered at that time, she would have been released from prison by now."

"But her life is over."

Over the years of being a police officer, Tang Zhexue has seen many criminals worthy of sympathy, just like the bloody handprint case he and Lin Dong handled at the beginning, every suspect who became a murderer is a victim of the deceased, at least from the perspective of the person involved From the point of view, only "life and death" can solve the problem.It is impossible for the law to cover everything. We can only hope that with the progress of society, the improvement of the legal system and the efforts of law enforcement personnel, such tragedies will be less and less.

"Erji, look." Lin Dong poked him with a curved arm, motioning him to look downstairs.

Through the window, Tang Zhexue saw Ou Jian and Cao Yuan standing in the shadow of the building downstairs. Ou Jian seemed to be trying to explain something, his body language was a little exaggerated, and Cao Yuan seemed to be wiping away. tears.If you think about it, you've become a criminal's dream lover, who won't let you go?

Faintly, he heard Ou Jian say: "Brother beat me up just now, sister, I'm sorry, I—"

Bang!See Cao Yuan slap Ou Jian and push the wall, then turn around and run away crying.

"Hey, this girl has strong hands."

Lin Dong gloated and exhaled smoke.
