Sancao City Police Station.

Qiao Chuan always felt that something was wrong when he first looked at the call logs, so he looked through the two most commonly used chat tools, and then he knew where something was wrong just now.

Judging from the call logs, the last call time was at half past three in the afternoon of the previous day, and there has been no call record since then, and from the two chat tools, the latest chat record is half past ten in the evening.

In this chat record at half past ten, the basic information of the person who chatted with the deceased Li Li is a woman, and the name of the remarks is Liu Yan, looking at the previous chat records, Li Li and Liu Yan have a close relationship, and there is a person in the chat records of the two people, but judging from the chat records between them, it is not possible to see who this person is, because in the expression of the chat records, this person has a title, "he".

Compared with the person who chatted with Li Li, Qiao Chuan was more interested in this "him", Qiao Chuan looked through all the contacts on his mobile phone and chat tools, Qiao Chuan had a strange intuition, this "he" was not among all the contacts.

No, in today's world where communication and the Internet are so developed, since the deceased often mentions this "he" to others, it will not not appear in the contacts in his hand, unless someone deliberately deletes all the information of this "him", is it the deceased Li Li who deleted it?

There is indeed such a possibility, after all, it can be found in the chat records between Li Li and Chen Yan that they have always called "him" between them, instead of calling him by his name, which shows that Li Li is still very strict in guarding this person's secret.

Or Qiao Chuan found that these problems in the mobile phone are just a habit of Li Li, you must know that some people's habit is to delete some more ambiguous and important information to prevent others from discovering anything.

But there is still a possibility, and Qiao Chuan even feels that this possibility is even greater than the previous one.

That is, this "he" was afraid that people would find out his true identity, so he deleted all the information of "him" in the deceased Li Li's mobile phone.

It seems that this person still has a certain sense of anti-reconnaissance, if this is really the case, then this "he" is likely to be the murderer.

This "he" still has a certain sense of anti-reconnaissance.

A thought suddenly flashed into Qiao Chuan's brain.

No, no, this is not logical, what is not logical?

Why didn't the murderer just throw away the phone at that time?

If "he" is the murderer, wouldn't it be better to destroy this phone?

In this way, isn't the connection between "him" and Li Li more difficult to investigate? Qiao Chuan suddenly felt that this case should not be so simple.

But in any case, the person who chatted with Li Li at half past ten this night was also the person closest to the time of Li Li's death, and was an important person.

In addition, Qiao Chuan also found a problem.

Just when he wanted to find the contact information of relatives in the deceased Li Li's mobile phone, he did not find that there were similar relatives' contact information in the mobile phone address book.

Even if there are no words such as "Dad" and "Mom" in the address book, he feels that Li Li's family may have a big problem.

This phone, hehe, do you think you can delete the call logs?

Qiao Chuan picked up his phone and asked the technical department to take the phone and arranged for them to check the call history of the phone after 3 p.m. on April 19.

After the technical department took the mobile phone away, Qiao Chuan looked at the time, it was already five o'clock in the afternoon, and it was so fast today, and no useful clues had been found, and several police stations had not replied to useful information about the deceased, just as Qiao Chuan was about to use some method to contact that important person, his phone rang.

It was Chen Ru who called, still in a cold tone, Chen Ru's age was three years younger than Qiao Chuan, and he was also Qiao Chuan's subordinate, but Chen Ru did not call Qiao Chuan "Qiao Team", but called him by his name, although some colleagues reminded Chen Ru, but she didn't care, after calling for a long time, no one talked about it.

"Qiao Chuan, the appraisal here is over, have you contacted her family?"

After getting Qiao Chuan's negative answer, Chen Ru said coldly:

"Come here, then."

In the past, the statutory identification center was a place that Qiao Chuan hated to go, when Qiao Chuan first became a criminal policeman, Sancao City was still Sancao County, and the statutory identification center at that time could not even be called a standard identification center, especially in the summer, there was not even air conditioning, and the forensic doctor would rather dissect in the hospital or in the funeral home, rather than pull the body to the statutory identification center of his unit.

In other seasons, it becomes cold, excessively quiet, and the smell of corpses due to poor air circulation, but since moving to this new office building, the legal identification center has also changed a lot, with a top-down ventilation system and a bright environment, but what has not changed is the coldness of the corpses in order to maintain the freshness.

Qiao Chuan walked into the autopsy center and looked at the person next to the dissecting table, this person carefully stitched the corpse on the dissecting table, stitch by stitch, as if he was stitching up a patient's wound on the operating table in the hospital.

Qiao Chuan had also seen several autopsies done by Chen Ru, and each time she always stitched them very carefully, especially when she touched a female corpse. She said that although they are dead, they still want to be as beautiful as they were when they were alive.

Qiao Chuan quietly watched Chen Ru finish sewing the corpse, and when Chen Ru took off his work clothes, he picked up the record book of Chen Ru's assistant and studied it in detail.

"Basically the same as the situation seen at the scene at the time, according to the digestion time of the food and the condition of the corpse spots, the approximate time of death was from 9 o'clock to 11 o'clock last night, except for the scar on the neck, there were no other external injuries or internal injuries on the body, the deceased had a fractured hyoid bone, and was strangled by a rope with a diameter of about 5 mm before his death, no fibrous residue was found on the neck, and the strangulation marks were smooth, which should be rubber, metal and other ropes with a smooth appearance, which were basically found at the scene that day, and there were some other finds."

Qiao Chuan pinched his chin, looked at the record book, and nodded slightly.

"A small amount of cortical fibers were found in the left fingernail of the deceased, which was tested as artificial leather, which should be that the deceased grabbed the murderer's clothes in the process of struggling, and soil was found in the nail of the deceased's right index finger, which was basically consistent with the soil composition at the scene after testing." This conclusion is what Qiao Chuan cares about the most, because the word "Feng" that is missing a horizontal line on the scene makes Qiao Chuan never let go.

"The deceased's lower body was old and ruptured, and semen was found in the deceased's body, which was ...... before the deceased's death"

When she said this, Chen Ru's voice trembled a little, and the following paragraphs basically popped out word by word. This is not the first time in Qiao Chuan's impression, Qiao Chuan thought, maybe it was because of Chen Ru, who is also a woman, hated the murderer.

"In this way, it may be a case of the murderer raping first and then killing." Qiao Chuan said.

Chen Ru rubbed his temples, "Well, the deceased's lower body is closed, ruling out the possibility of raping the corpse after death, and there is another thing worth noting." ”

"Oh?"

"Look here." Chen Ru pointed to the neck of the deceased, "The strangulation marks on the left side of the neck are deeper than the strangulation marks on the right side, which means that the strength of the murderer's left arm is greater, which shows that under normal circumstances, the murderer is likely to be left-handed." ”

Qiao Chuan looked at the corpse, Chen Ru's dissection of the deceased's trachea just now drew a line in the middle of this neck, and it was obvious that the strangulation marks on the left side were deeper than the strangulation marks on the right side, Qiao Chuan leaned down and looked at the back of the deceased's neck, there were no strangulation marks behind it, so it was determined that the murderer strangled the person to death in a normal way.

"There is no doubt about it, I am also afraid that the murderer's right arm will be wound counterclockwise with a rope, and then cause the left and right hands to be reversed, that way is indeed easier to exert force, but a white spot was found on the waist of the deceased, which should be the murderer when he strangled the deceased Li Li with his knees against her, the kind of strangulation method you suspect does not need to be so troublesome."

Qiao Chuan smiled awkwardly, indeed he suspected that it might be that kind of strangulation, after all, there are not as many right-handed people as in detective novels.

However, there is one detail that Qiao Chuan thinks is very strange, according to Chen Ru's autopsy report, Li Li's posture before death should not be in a state of lying down, and the state of lying down will not make Li Li's back appear white spots, but if it is not the way of death lying down, the appearance of the word "Feng" on the ground seems unreasonable.
