Criminal Investigation: Forbidden Rose

Xia Yi stared at the adoption file of "Zhang Shengnan" dumbfounded: "Damn it, so before the dumb case was exposed, she had planned ahead by pretending to be a victim and tricking other kidnapped children into trusting her!"

Shao Lin pondered for a moment, then nodded: "No wonder Xu Yunfei said that this 'Zhang Shengnan' kept telling her that life at sea might not be so bad. She probably did this to keep these kidnapped children safe. If I'm not mistaken, this 'Zhang Shengnan' has a high status in the human trafficking route. Her childlike appearance is very easy to deceive other people's trust, which can be said to be unique."

"It's impossible for an 11-year-old girl to be able to do such a thing?!" Xia Yi yelled, "How old is this girl? What kind of magic medicine did she take, why didn't she grow up? Go How great is it to shoot an advertisement for that skin care product? Why do you have to do this kind of blood-licking thing?!"

"Team leader, team leader," Yan Jingjing leaned over, "I was watching a show that day, and the special guest was also a younger brother, who looked only 10 years old, but was actually 31 years old, called Hai——hai, what kind of syndrome? "

Shao Lin continued: "Highlanders syndrome is very rare, but it does happen. However, in medicine, it is not yet a clear disease."

"That's right, that's right!" Yan Jingjing's eyes lit up, "It's so cool, I finally have a case to blow up at the next class reunion—" Before I could finish speaking, Xia Yi hit the head: "First Catch people and blow them!"

When it comes to arresting people, a group of people are full of worries.

According to people from the orphanage, on the day He Lianyun took the child away, the original plan was to take the little girl to buy a skirt, and then take her to eat KFC that she had been talking about for a long time.After all, in the orphanage, being able to eat KFC once is something worth showing off.This incident was later confirmed by the police—according to the consumption records on He Lianyun's mobile phone, he did indeed have consumption records at a certain KFC in the West District the night before the accident.

According to the payment time, Shao Lin adjusted the surveillance at the entrance of the restaurant, and indeed captured the scene of He Lianyun taking the little girl out. "Zhang Shengnan" has already changed into the princess dress that He Lianyun bought for her newly, and walked out hand in hand with everyone, looking very intimate, without the slightest sign of affection.The two walked towards the parking space and quickly left the camera, probably to pick up the car.

This was the last time the police saw "Zhang Shengnan".

On the day of He Lianyun's accident, Yan'an City issued a notice to search for "Zhang Shengnan", and found nothing. What's even more strange is that even He Lianyun's community camera did not capture the image of the little girl, and the security guards guarding the door did not. no memory.

As a result, the police not only did not have Zhang Shengnan's real identity, but also did not specify when she left He Lianyun's community.

This thing is very strange.Shao Lin thought about it, assuming that "Zhang Shengnan" entered the community in He Lianyun's car, how did she get out?He Lianyun lives in a high-end residential area, there are only two gates in total, and she was not photographed.Moreover, there are cameras and infrared alarm nets on the iron fences, so there is no possibility of digging out from other places.

Perhaps, she has an accomplice?Did he drive away with "Zhang Shengnan", or did the little girl hide in the other party's house until a few days after the case, before leaving secretly?If there is an accomplice, it will be even more difficult to check. The little girl only needs to wear a mask and hold hands with an adult-who would doubt such a pair of parents and children?

Or maybe, Zhang Shengnan left very early and never came back with He Lianyun at all?

But Shao Lin didn't have any evidence.

The police even checked, after He Lianyun's car returned to the community, all the license plates that left the community, even taxis and rides, but found nothing.The "little girl" who had previously pretended to be Zhang Shengnan disappeared from the police's field of vision in such a confusing way.

Three days later, Interpol also issued a wanted list for the woman.

Not only was the criminal investigation deadlocked, but the forensic team was also extremely busy.According to the bones, it is not difficult to judge that the body found in He Lianyun's mansion was a man in his 50s.After DNA testing, it was consistent with the hair DNA found in He Lianyun's office, and there seemed to be no problem with the source of the corpse.

But the forensic team still needs to determine whether this is suicide or homicide, and whether the deceased was burned alive, or whether the fire just covered up a corpse dumping scene——

However, due to the severe burns on the corpse, some of the exposed bones were also very fragile and would break if touched. As for the carbonized epidermis, under a microscope, Yu Min could not analyze whether there was any "life reaction".

Due to the presence of the combustion accelerant, the flame ignited much faster than a natural fire, and the contents of the deceased's skull expanded and exploded rapidly when heated, resulting in a fracture of the skull. It is also impossible to judge whether there is a "goose claw" change in the corners of the eyes of the deceased. is still alive.

If a person is burned alive, before he dies, his trachea and even his lungs will be scalded by the scorching gas. At the same time, if he does not control his breathing, he will swallow a large amount of soot and charcoal.However, when the forensic doctor took out the blackened digestive tract section and put it under the microscope, he found almost no signs of life, and the internal trachea section showed no signs of heat-induced respiratory syndrome.

"The body was burned too badly," said Yu Min, who lost his usual indifferent self-confidence when making the report, and even felt a little embarrassed. "We thought that the deceased had died when the fire burned, but the cause of death is still open to question. We couldn't Any deadly poison was detected in the body, but a small amount of sleeping pills was found—though we cannot actually determine the concentration of the poison, because many chemical bonds are broken down and changed at that high temperature, which greatly affects the accuracy of the measurement results."

"But there is one thing. The skin burns on the upper body of the corpse are far more serious than the lower body of the corpse. In other words, the spontaneous combustion agent is likely to be sprinkled on this person irregularly, mainly on the upper body." Yu Min paused , "Combined with our belief that the body was dead when it was burned, combining these two clues, we believe that homicide is more likely."

"I also agree with the homicide." Shao Lin proposed, "A few hours before He Lianyun died, he was still revising a letter with suicidal tendencies, but he did not send it——Based on what I know about Mr. He, even if he committed suicide, he must have committed suicide. I will write my suicide note clearly, and I will not store it in the draft box without sending it.”

How does a little girl deal with a grown man?

Only medicine.

He Lianyun's family did have sleeping pills.

But why did "Zhang Shengnan" suddenly become murderous?If she wanted to leave, she could have found an opportunity to "disappear" so as to avoid the possibility of revealing her identity.Her body is her unique advantage, there is absolutely no need for it to be known to everyone like it is now.

In other words, her act of arson must have a deeper purpose.

According to the letters that He Lianyun kept in the draft box, he obviously knew some information.However, what kind of information did He Lianyun have that forced "Zhang Shengnan" to leave in such an extreme way?

When he walked out of the meeting room, Shao Lin still hadn't figured out the case in his mind.In his peripheral vision, it seemed that someone waved his hand at him.Shao Lin turned his head and found that Yu Min was holding a document in his hand, and he winked at himself.

Shao Lin understood, and quickly got up and walked over.Yu Min pushed open a small room where she was making a phone call, her face seemed a little heavy: "I have the result of what you asked me to investigate, sorry for the delay, these days are really busy."

Wang Yangchun and He Lianyun were involved in successive crimes, and Shao Lin himself forgot that he had secretly asked Yu Min one thing before—the notes that the puppies kept barking after sniffing them.

"The writing that you suspect is blood," Yu Min frowned slightly. "The reason why the color is bright red is because it was mixed with bright red dye, but the luminol reaction is very strong, which proves that the ink does contain blood."

Shao Lin had no expression on his face, but his heart clicked, quietly waiting for Yu Min's next words.

"I tried to extract the biological information, but I really didn't expect that DNA was extracted from the blood. Recently, the case has been sequenced several times, so I simply submitted it together." Yu Min handed over a report.

Just as Shao Lin was about to take over, Yu Min pulled back the report and stared at the other party seriously: "I hope you will be prepared."

Shao Lin only felt that his heart was sinking even more, but he still pretended to be relaxed and smiled, saying that there was nothing unacceptable about it.

"I didn't find any 100% match for this DNA in the database." Yu Min turned her head and looked outside the door, and then lowered her voice after making sure no one was walking this way, and handed over the report, "However, the person with the highest matching degree It's you."

"What do you mean?" Shao Lin narrowed his eyes slightly, "Could it be my blood? It's not a 100% match because the DNA has been damaged after being placed on paper for a long time?"

Yu Min shook his head silently, opened the identification report - 50% match - there was Y under the chromosome microscope, this blood was most likely from his biological father.

Shao Lin only felt a "boom" in his ear and froze in place.After a while, he forced a stiff smile: "I don't know much about this, but I would like to ask Director Yu, how long can blood DNA be preserved?"

Yu Min frowned slightly: "What do you mean? You mean, how long will it take to degrade?"

Shao Lin only felt his chest "thumping" and nodded, "For example, if there is a tube of blood that has been released for more than ten years, nearly twenty years, can you still come up with DNA?"

"Almost 20 years?" Yu Min raised his eyebrows, "It must be processed, and stored under laboratory conditions, there is no problem." He raised his head and pointed to the document, "But you put it in ink, ten years and twenty years , Absolutely impossible. Even if it is written on a card, I am afraid it will be gone in 20-2 years. No matter how stable the DNA is, it will slowly degrade when exposed to air. Therefore, I am also very surprised that the DNA can be extracted from it this time. It seems If you encounter such clues in the future, try to try as much as possible.”

Shao Lin's mind turned very fast: "You mean, the blood in this ink, this blood was added recently?"

Yu Min nodded.

Shao Lin's Adam's apple moved, but he didn't speak again.

Could it be that Lin Yun was really still alive? !

"Shao Lin, I don't know why you asked me to test this." Yu Min looked at him seriously, a trace of worry flashed in his eyes, "Now I am willing to help you keep it a secret, but if in the future, this matter becomes a potential clue , I will submit it without hesitation, I hope you can understand."

Shao Lin thanked repeatedly stiffly, saying it was natural.

Yu Min nodded expressionlessly, said "You can do it yourself", and was about to turn around and push the door, but at this moment, she bumped into Xia Yi who was walking this way.Enthusiastic policeman Xiao Xia had big bags and small bags in his hand, led them to buy drinks for everyone, and just came back from the reception room to get takeout.

Someone in Xia narrowed his eyes suspiciously, and turned his unfriendly eyes on Yu Min's face: "Hey, in broad daylight, you two are lonely and widowed, why are you whispering together?"

"..." Shao Lin gave him a pale smile, "I wanted to ask Director Yu about something before..."

Xia Yi's face changed, and his expression instantly turned into an eager and loyal big dog, and quickly stuffed a cup of his favorite Rox Bear American No Sugar in Shao Lin's hand: "Baby, it's getting hot today too Why are your hands still so cold? Drink something warm."

At the same time, he glanced at Yu Min strangely: "What are you looking at? Do you want it? I want to tell my brother earlier next time, and I will order it for you too—"

Yu Min lowered her eyes, impatient as if avoiding some pathogen, without turning her head: "Excuse me."

Shao Lin: "..."
