Qianshan Xue, who had a beautiful face, looked at Mr. Lu with serious eyes in dismay, and said helplessly: "Mr. Lu, whether he is still alive or not, we will investigate, can you tell me about the third suspicion you think?"

Hearing this, Mr. Lu's eyes immediately widened, and he said: "The third suspicion, and the biggest suspicion in the whole case, is that I think this criminal is not careful to wipe off his fingerprints every time, but he has no fingerprints at all. ”

These words stunned everyone present.

Elle was stunned, "What are you talking about?" I don't understand. ”

Mr. Lu said: "He has committed hundreds of crimes, covering all over the country, but no police officer has extracted any useful fingerprint information in any case. ”

Ye Xiaolei looked at the contents of the file on the tablet and said: "Yes, no valid fingerprints were extracted, so the police unanimously determined that this criminal's anti-reconnaissance ability is quite strong, and he is challenging the police." ”

When Mr. Lu heard this, he lowered his head slightly, looked at Ye Xiaolei from the frame of his glasses, and said: "There is an old saying in Huaxia, how can you always stand by the river without getting your shoes wet, if he committed the crime four times and did not leave fingerprints, it can also be said that he was cautious, but there were more than 400 cases without leaving fingerprints, isn't it too strange?"

"It's possible that he was wearing gloves. Ellie said.

Mr. Lu said with a bright look in his eyes: "There are no traces of gloves that may be found at any scene, there are no rubber fragments, there are no woven fibers, and even if there are, they are also on clothing, which is almost ironclad evidence, this criminal has no fingerprints." ”

Qianshan Xue was surprised, looked at the file and said: "The recorded information has not extracted any valid fingerprints, if it is really so sure, why not record it?"

Hearing this, Ellie raised her eyebrows and said: "Because that's impossible, because even if someone uses a grinding wheel to grind off their fingerprints, it won't be long before it grows out, and even if it is cut with a knife, it can also be used to restore the fingerprints." ”

Mr. Lu looked at Ai Li with admiration and said, "That's it, back then, experts thought that this suspect was a big truck driver or a salesman who ran business everywhere, but I was very confused about fingerprints, so we went to investigate." ”

"At that time, the fingerprints worn by the workers of the scrub factory were quite bad, so we wondered if this criminal would have lost his fingerprints because of his work, but the results of the investigation were very disappointing. ”

"That's the workers in the scrub factory, and the fingerprints are really worn, but not all the fingerprints are gone, but some of them are missing, and not every finger is like that. ”

Hearing this, Qianshan Xue was surprised: "Is it possible that the skin of his palms has been burned, so there are no fingerprints, only scars?"

Looking at Qianshan Xue, Mr. Lu said: "We have done an investigation, and almost all the men who were in the provincial capital at that time and had burns on their palms were the targets of our investigation, but the result was that their suspicions were ruled out. ”

"What about the other aspects? Are there any doubts that are not recorded in the file?" asked Ellie.

Mr. Lu said: "Except for these three doubts that cannot be recorded, other information is clearly recorded. ”

Hearing this, Shen Qiang got up and said to Mr. Lu with a smile: "Thank you for finding the murderer for us." ”

Mr. Lu was stunned for a moment, and then said in shock: "What did you say? What I said helped you find the murderer?"

Shen Qiang smiled and said: "Yes, but the specific details can't be told to you yet, but the information you provided has already found the direction for us to solve this case." ”

"It should be, it should be!" Mr. Lu's eyes were bright.

After sending the four people away, he stood quietly at the door of the community, his eyes full of anticipation.

In the car, Qianshan Xue, who drove away, was full of suspicion, and said in surprise: "Shen Qiang, have you really found the murderer?"

Hearing this, Ye Xiaolei and Ai Li, who were sitting in the back row, immediately lit up their eyes.

"Shen Qiang, you shouldn't be deliberately teasing us, the three suspicious points recorded by Mr. Lu himself should have been denied by the police, otherwise, they should be recorded in the file. Ellie said.

Ye Xiaolei also said anxiously when she heard this: "That's right, first of all, Mr. Lu suspects that the murderer has accomplices who helped him escape the arrest, this possibility can be basically ruled out, but he may be a cultivator, as for his intuition, saying that the murderer is still alive relies on intuition, and there is no evidence at all, so of course it will not be recorded." ”

Ellie frowned and added: "Then there is only the third possibility, that is, the suspicion that no valid fingerprints have been extracted, but with this alone, you can't find the murderer, so you were just comforting that old gentleman?"

Shen Qiang smiled, glanced at them in the back row from the rearview mirror in the car, and smiled: "I'm a person, I never joke in important places, and don't forget, I'm a doctor." ”

Ai Li and Ye Xiaolei looked at Shen Qiang with a confused expression.

"What does the doctor have to do with this case?" Ellie raised her eyebrows, "At that time, all the men in the provincial city with burns on their palms were investigated, and the youngest of them was even only twelve years old, but nothing was found. ”

Hearing this, Shen Qiang smiled and said: "The problem is here, this is a common-sense loophole, common sense tells us that everyone has fingerprints, unless the scar will be erased, but in fact, in addition to the scar, there is a kind of person in this world who is born without fingerprints." ”

Chirping!

Hearing this, Qian Shanxue parked the car on the side of the road, looked at Shen Qiang in shock, and said, "What did you say?

Shen Qiang smiled, and then said: "Yes, the fingerprints of human fingers and toes are fingerprints, which begin to form when the fetus is 11 weeks pregnant, but if there is some kind of genetic mutation at this time, then the body will never make a signal to form fingerprints." ”

"So it's a disease, and scientists believe it's caused by a lack of keratin 14. This defect causes the body to mark the death of the cells in the outer layer of the skin, and as a result, people with this disease do not have fingerprints, so usually, we refer to this condition as afingerprint, more technically known as Nargli syndrome. ”

Qianshan Yukimei said in shock: "What you said is true?"

Shen Qiang raised his eyebrows and smiled: "Of course it's true, this case happened decades ago, when the news was closed, there are very few people with no fingerprint in the world, and no fingerprints in the vast majority of the time, it does not affect normal life." ”

So it was not until recent years that with the popularization of fingerprint locks in electronic products, the lives of people without fingerprints began to be troubled, and this disease attracted the attention of some medical scientists and scientists. ”

"At that time, there was no record of no fingerprints, and the police records only wrote that no valid fingerprints were extracted at the scene for the sake of rigor, so no one realized that the murderer was a patient with obvious characteristics. ”
