"What?" Hong Qifeng was taken aback: "Can you be sure?" ”

"Yes, we couldn't find it in the system, but later because Han Sui left fingerprints when he came to identify the body, when he entered it, he found that it matched the fingerprints on the handle of the knife."

"Okay, I see, if there are any other clues, we will communicate in time."

After hanging up the phone, Liu Haoran excitedly leaned over and asked, "Team Hong, is there really a new clue?" ”

Hong Qifeng nodded while thinking about it, and said, "Hmm." ”

"So what's the next step now?" Liu Haoran asked.

"Call Li Yunbai, let's go to the forensic identification center."

After a while, Liu Haoran called Li Yunbai, and the two of them ran quickly in front of Hong Qifeng.

For young criminal policemen, it is always very positive to follow the captain to investigate the case, which can not only quickly learn practical experience, but also avoid dealing with boring paperwork in the office.

Hong Qifeng came to the garage with two young criminal policemen, and as soon as he took out the key, Liu Haoran rushed to say, "Team Hong, let me drive, right?" ”

When Hong Qifeng heard this, he happily handed him the key, and half-jokingly said: "The public car, if it is broken, you will have to deduct your salary." ”

Li Yunbai also echoed and said: "Team Hong, don't worry, he drives really well, I have been in his car." Besides, if it's really going to be broken, let him work for nothing in the team for two years. ”

Liu Haoran was full of confidence: "Don't worry, I'll drive slowly." ”

Liu Haoran got into the car and ignited the car, started the car, and drove in the direction of the appraisal center.

The forensic identification center is located in a separate compound of the Binhai Armed Police Hospital, not far from the Public Security Bureau, and it takes about 10 minutes to drive there.

As soon as Hong Qifeng got out of the car, he went straight to the office of He Mo, the director of the appraisal center.

He Mo was sorting out the information, and he didn't seem surprised at all when he saw Hong Qifeng coming.

She continued to sort out the information and said, "I was still thinking about when you will definitely come, don't worry, I am sorting out all the evidence collected so far in this case, and I will report to you immediately." ”

Hong Qifeng smiled and said, "No hurry, no hurry. He motioned for the two young men to sit down on the sofa next to the desk first, but they didn't sit down by themselves, and slowly slipped to the table where He Mo had piled up a pile of things.

Before he could get closer, He Mo raised a hand and stopped: "Stop, didn't you say that you are not in a hurry?" What are you going to do with me? He waved the documents in his hand again and said, "There are too many documents here, and I will have to start sorting them out again when I mess up." ”

Hong Qifeng had no choice but to retreat to the sofa and sit down.

Liu Haoran and Li Yunbai, two young criminal policemen, saw such a scene for the first time, and looked at each other suspiciously: Who would have thought that there would be anyone in the entire public security organ who would dare to talk to Team Hong like this? Even the director had to respect him a little when he saw him.

Fortunately, the waiting time was not long, and He Mo had already neatly sorted out the documents, divided them into three parts, and then prepared to take them to the coffee table in front of the sofa in turn.

Seeing this, Liu Haoran and Li Yunbai stood up and were about to go up to help, but they were all stopped by her with a wave of her hand.

The two young men had to freeze their bodies in the air and watch her take it herself.

After everything was put away, she sat down, gently brushed the hair scattered on her forehead behind her ears, took a breath, and began to say: "There are three parts here, one is the scene photos, one part is the corpse characterization report, and the other part is the particulate examination report and trace report that I brought back. The order and position must not be messed up. ”

These words were said to Liu Haoran and Li Yunbai, two young people, who wanted to help stop them just now, and He Mo explained it to them clearly.

"Then tell us more about it." Hong Qifeng motioned for everyone to sit down, and then asked He Mo.

He Mo nodded: "Well, I also mentioned to you on the phone in the morning, judging from the characterization of the deceased's body, the time of death should be 3-5 days ago, and then we compared the weather conditions and the environment of the corpse scene in the past few days, and further judged that the time of death should be about 72 hours." ”

Hong Qifeng nodded, but he didn't interrupt He Mo's words.

"Judging from the groove on the front side of the neck of the deceased, between the thyroid cartilage and the hyoid bone, it goes around the sides of the neck, goes diagonally up along the angle of the mandible, and then rises into the hair, and forms a levitation in the occipital region, which is commonly known as 'the figure of eight'."

He Mo said a bunch of professional terms, which made Liu Haoran and Li Yunbai hear it in a fog.

"A typical self-hanging?" Hong Qifeng asked.

"I can only say that in terms of the shape of the ditch, it is generally judged in this way."

"You mean ······" Hong Qifeng asked. "Is there any doubt in this?"

He Mo nodded slightly, flipped out a photo from the scene photo, and handed it to Hong Qifeng: "This is the rope used by the deceased to hang himself." ”

Hong Qifeng took the photo, and He Mo continued: "The tying method of this rope is quite special, you see here, generally people who hang themselves will choose to put the rope through a fixed object, and then tie a knot to form a circle, and then stretch their necks into it to complete the hanging." ”

He Mo said as he drew a rough shape on the blank paper with a pen.

"This one is different!" Hong Qifeng said firmly.

"Yes," He Mo continued, "the rope used by the deceased to hang himself in this case is to tie one end separately into a slipknot rope sleeve, and the other end is tied to the movable rope of the rope sleeve, which is very unique. ”

"Oh?" Hong Qifeng was puzzled.

"This kind of system is very fatal to people who hang themselves. Because once the slipknot rope is wrapped around an object, such as a person's neck, as long as the gravity pulls slightly, it is almost impossible to break free, because it will only struggle tighter and tighter. ”

"In other words, if you hang yourself with this kind of rope, you will repay your determination to die?" Hong Qifeng asked: "Or is this rope noose not tied by the deceased himself?" ”

"The question you asked belongs to psychology, I'm not good at it."

He Mo refused to answer Hong Qifeng directly, and continued his topic: "I checked, the tie method of this slipknot is a bit like the tying method that fishermen tie when they are fishing. ”

Hong Qifeng nodded, looked at the photo of the rope, and asked, "Are there any other doubts?" ”

"In addition, this kind of rope is not a rope commonly used in ordinary home life, but it is also very similar to the rope used by fishermen on fishing boats, which is light and strong and has a strong load-bearing capacity, and will not be easily broken."

Hearing this, Liu Haoran on the side explained: "This shouldn't be strange, Mrs. Han worked in the fishing tackle factory for Nian Nian Yu earlier, and she has a net rope for fishing boats and is familiar with the rope tying method, it should be normal, right?" ”

He Mo shrugged: "There is also such a possibility." ”

"But her son Han Sui is now also working in the Fishing Tackle Factory, and he is also the deputy director." Li Yunbai expressed his different opinions.

After finishing speaking, both of them looked at Hong Qifeng to see what his opinion was.

But Hong Qifeng didn't seem to hear what they said, he just looked at the rope on the photo, and didn't answer any of them.

He Mo saw that he stopped there for a long time and didn't move, so he couldn't help but pull the photo back from Hong Qifeng's hand and put it back in the photo pile.

He took out the photo of the deceased again and continued to say quickly: "The deceased's cheeks were swollen, cyanosis, petechial bleeding, rose teeth, and urinary incontinence. These are typical features of hanging, and there is nothing particularly suspicious. ”

Speaking of this, He Mo paused, pointed to a place in the photo and said: "This is what I mentioned to you before, there are abrasions on the front of both knees, but they are very slight, and they should not be signs of serious violence." ”

"Under what circumstances would this kind of injury occur?" This time it was Li Yunbai who asked.

He Mo picked his eyelids and glanced at Li Yunbai, and replied: "There are too many cases that can produce this kind of scar, because this mark is very slight, generally rubbing on the table leg, accidentally falling on the floor at home, or holding your knees against a hard object for a little longer will cause this kind of mark." ”

"What about kneeling?" Hong Qifeng asked suddenly.

He Mo was stunned for a moment, then picked up the photo, looked at it again very seriously, and slowly nodded and said, "I don't rule out this possibility." ”

Hong Qifeng bowed his head slightly. Seeing that he had no other questions, He Mo continued: "The characterization of the corpse is probably like this. ”

After saying that, she began to look through the pile of photos again, and finally turned out the photos of the knife and a bunch of materials, and then said: "This is the knife found at the scene, and we found two different fingerprints on it." ”

As he spoke, he took out his pen and drew a circle on the blade and handle of the photo. Pointing to the circle on the body of the knife, he said, "This is where the fingerprints of the deceased appeared, and judging from the arrangement of the fingerprints, it should have caught the back of the knife like this." ”

He Mo said as he gestured with his hand in the direction of grasping. Then he pointed to the circle on the handle of the knife and said, "The fingerprints of the deceased's son have been found here, which are the fingerprints of Han Sui, who came to identify the body that day." ”

"So," Liu Haoran interjected, "Maybe Han Sui stabbed Mrs. Han with a knife, and Mrs. Han grabbed the knife with her hand and snatched the knife?" ”
