It took a long time to finally get them on the right track. As long as you follow this clue, you will soon be able to find the murderer.

The task was completed, and Chen Mengran did not plan to waste any more time and bid farewell to Xue Guozheng.

"Wait a minute. Xue Guozheng stopped Chen Mengran.

"It's all your speculation just now, and there is no actual evidence to support it, how can we police believe it. ”

"As long as you follow this clue, find the suspect, interrogate him, and compare the suspicious hairs at the scene, you will naturally know whether my guess is correct. Chen Mengran said.

saw Xue Guozheng shook his head: "That's not good, our police manpower is limited, and it is impossible to waste police force and time because of your speculation." ”

"And how are you going to believe it?"

"From your speculation just now, it can be seen that your reconnaissance logic is very strong, in this case, can you guess something we know from the scene, and let us open our eyes. In this way, it can also be proved that what you just said is pure thinking and logical speculation, and not just words. ”

"Is this a test for me?"

"I think too much, I just want to see if you really have that strong detection ability. ”

If you are kind enough to help, but others doubt your ability, in a popular phrase, it is a hot face and a cold ass.

Chen Mengran feels this way now, he was kind enough to help them find clues, but in the end, his ability was questioned, which made him a little angry.

If it was just to help these policemen solve the case, Chen Mengran would not have to prove anything and leave directly. It's a pity that it's not them who he really wants to help, but the old man. He wants to find the murderer and free the old man who died in vain.

"Okay, then I'll speculate on something you know. Chen Mengran paced back and forth in the dilapidated rental house with his hands behind his back. Eventually, I walked over to the picture on the table and picked it up.

"If my guess is correct, the man in this photo is the son of the deceased, the woman is the daughter-in-law of the deceased, and the little girl is the granddaughter of the deceased. ”

"I can see that, too. The young policeman said, his tone mocking.

"Then you must not see that the deceased's son has passed away, and the daughter-in-law has run away with another man, leaving the deceased and his granddaughter to depend on each other. ”

The young policeman was startled and blurted out, "How do you know?"

Not only him, but Xue Guozheng and the two forensic doctors were all surprised.

"Seemingly, I guessed right. Chen Mengran said with a smile.

Xue Guozheng didn't deny it, and said, "How did you know this from just one photo?"

Chen Mengran pointed to the man in the photo and said: "You see, in the photo, the man's image is whiter than his wife and daughter, which is the result of rubbing his hands for a long time. There was a lot of rags in the rental house, and the whole house was covered with dust. If the photo is placed on the table, a lot of dust can accumulate in a day, and the deceased will have to look at the photo, so naturally it will be wiped clean. But then again, if the deceased could see his son every day, he naturally did not need to look at the photo, so it can be inferred that the deceased had not seen his son for a long time, and as soon as he missed his son, he would take out the photo and wipe the dust from the photo with his hands, and over time, the image on the photo would naturally be rubbed white. ”

"Even if you haven't seen his son for a long time, it doesn't necessarily mean that he is dead, maybe his son is working elsewhere and won't come back for a long time?" said the short and fat medical examiner.

"There is such a possibility, but Pingjin itself is one of the best big cities, and his son can't afford to go to work elsewhere. Moreover, if he just went out to work, his son would definitely call every once in a while, and the deceased would not have to hold the photo often. ”

"Makes sense. ”

"So, how did you know that the deceased's daughter-in-law left him and his daughter and ran away with someone else?" Xue Guozheng asked.

Chen Mengran pointed to the woman in the photo and said: "Compared with her husband, the woman's image is black, which is due to the dirt accumulated from the falling dust if she has not wiped it for a long time. It shows that the deceased never looked at his daughter-in-law before his death, and even hated her. Looking at his granddaughter again, the image is also a little white, but it is shallower than his son, indicating that the old man often misses his granddaughter, but when he can meet his granddaughter, he does not miss his son as often. Combined with the above, it can be inferred that the deceased's daughter-in-law abandoned them, followed other men, and never returned. ”

"It's a god. Humpty Dumpty forensic doctor gave Chen Mengran a thumbs up.

With so many clues in one photo, this is a contemporary detective.

"I don't believe you're speculating, you must have heard about the deceased from the mouths of bystanders while you were watching. The young cop said.

He doesn't believe that people's inference ability is so strong, those detectives who deduce a lot of information from a tiny detail only exist in zài novels, and the detectives in reality can't be so good.

"If you don't believe it, well, I'll tell you something you don't know. The calluses on the deceased's left hand were thicker than those on his right hand, indicating that he was left-handed. The deceased's footprints are shallow on the left and deep on the right, indicating that there is something wrong with his left foot and he usually walks with a limp. The deceased's teeth were yellow, indicating that he smoked regularly, but the skin between the index and middle fingers of his left hand was not visibly yellowed. The color of the skin changes over time, but the teeth do not. This means that he has been quitting smoking for a while, at least for more than a year. The deceased's quilt was worn out, but it was neatly folded. A person who is so embarrassed in life is so attentive to folding quilts, this is probably a habit. And the reason for this habit is likely that he used to be a soldier. I also found a circular scar on his lower abdomen, which was a gunshot wound, and from the size of the wound it was not like a pistol, but more like a rifle. Judging from the healing process of the scar, the gunshot wound is at least 30 years old. More than thirty years ago, our country fought with Vietnam, and I guess, the old man also participated in that battle. It's just that I don't understand one thing, how can such a person who dedicates his life to the country have such a miserable life in his old age, and the government doesn't care. ”

After speaking, Chen Mengran looked at Xue Guozheng, but saw that the other party was shocked. Not only him, but everyone was shocked.

"If you still don't believe it, you can go to the neighbor of the deceased to check. ”

"No, I believe you. Xue Guozheng took a deep breath to calm the shock in his heart. Then he said to the young policeman beside him: "Send all the free manpower to visit the surrounding lottery stations and find out who bought the lottery ticket for the deceased." ”

"Yes. ”

The young policeman departed.

The murderer accompanied the old man to buy a lottery ticket, so it was easy to find out. I believe that there will be results in these two days.

After getting out of the dilapidated rental house, breathing the air outside, thinking of the scene just now, Chen Mengran wanted to laugh.

The so-called speculation was actually Chen Mengran who knew the answer, and then made it up with the so-called logic. Even so, the ability to pretend to be a ghost frightened everyone.

"My cousin just now, doesn't it look like a detective?"

"Like, but like a joke. The lone wolf scoffed.
