Chapter 84
In the morning of the next day, He Jiahui returned to Hong Kong Island by boat, then went directly to Kowloon, went to the identification center of the forensic department, and met the beautiful forensic doctor Wen Jiaxi.

Although the investigation of the case has fallen into a bottleneck, He Jiahui is a little troubled.But seeing beautiful women early in the morning is still very refreshing.

Knocking on the door of Doctor Wen's room, a voice of "please come in" came from inside.

"He sir, are you here so early?" Dr. Wen greeted.

"I was afraid of traffic jams, so I took the early boat." He Jiahui continued, "Zheng Jiazhen's preliminary autopsy report should be out, right?"

"It's only been two days, you are in a hurry." Dr. Wen was looking for the autopsy report on the computer while talking.

He Jiahui said: "All the clues I found before have been overturned, and I can't find any new clues for the time being, so I can only use the forensic doctor and the forensic evidence to see if there are any clues.

Doctor Wen nodded and continued: "Zheng Jiazhen's autopsy report is not finished yet, so I can't give you a written report, but I can tell you about the results of the current autopsy, hoping to help you solve the case.

According to the autopsy results, the deceased was indeed suffocated because of compression of the neck.Only one constriction groove was found on the neck of the deceased, and there was a certain degree of exfoliation of the epidermis and subcutaneous bleeding.

The deceased's hands, feet, calves, and forearms had dark purple spots and scattered bleeding points. After the rigor, the toes were still drooping. These all proved that the deceased was hanged.

We found no obvious bruises and wounds on the body of the deceased, and no traces of fighting with others. We also examined her lower body and found that she had not been violated. "

"What about the time of death? Is it still between two in the morning and four in the morning?" He Jiahui asked.

"The time of death is consistent with the judgment when measuring the liver temperature at the scene, which is between [-]:[-] am and [-]:[-] am." Dr. Wen replied.

"Did you find any foreign objects between the dead man's nails? Like dander tissue?" He Jiahui asked again.

Dr. Wen shook his head: "No, only her own skin tissue and her own blood were found in her fingernails, which should be left when she tried to break free when her hands were bound."

Upon hearing this result, He Jiahui sighed lightly. It seems that the forensic doctor can't provide useful information for solving the case.

Dr. Wen continued: "One more thing, we found residues of GHB in the body of the deceased."

"GHB? Y-alkyl butyric acid?" He Jiahui asked immediately.

Dr. Wen nodded in surprise, she did not expect He Jiahui to be able to name the scientific name of this substance.

As a former anti-narcotics policeman, He Jiahui is no stranger to this thing.

Y-alkylbutyric acid is the first category of psychotropic drugs under control, which can have a strong inhibitory effect on the central nervous system, and is often used by criminals to make narcotics and drugs.

He Jiahui breathed a sigh of relief: "I finally found some useful information! It seems that Zheng Jiazhen was sober before she was hanged."

"Why do you have such a judgment?" Dr. Wen asked puzzled.

He Jiahui explained: "There is a drug in the deceased's body, which means that the murderer stunned the deceased and then tied him up. Therefore, the deceased did not resist, nor did he fight with the murderer. The murderer's skin tissue was not found between the nails.

The hands and feet of the deceased obviously showed signs of struggle, which means that the deceased was awake again after being tied up.Therefore, I judge that the deceased should have been awake when he was hanged.If she had been hanged unconscious, there would have been no struggle. "

"I didn't expect Sir He to be so young and have such good insight and reasoning skills!"

The forensic doctor Wen nodded suddenly, and at the same time looked at He Jiahui with a hint of admiration.

……

He Jiahui went to the forensic department again and found the forensic witness Gao An.

After seeing Gao An, He Jiahui handed over the newly found bundle of ropes to Gao An.

"Gao sir, we found this from a suspect. Please analyze whether this bundle of ropes is the same as the one that hanged the deceased."

Gao An looked at the rope, and said, "On the surface, the color, thickness and material are all the same. Whether it is the same rope or not will have to be tested, and it will take about two hours."

"No problem, I can wait." He Jiahui paused, and then asked: "Gao sir, is there any new discovery of the evidence taken from the scene before?"

"I have examined the rope that bound the deceased and the rope that the deceased hanged himself. After comparing the cuts, I can confirm that it is the same rope that has been cut into three sections. One section is used to hang the deceased, and the other two sections are used to bind the hands and feet of the deceased.

On the rope, I only found the blood and skin tissue of the deceased, but not others.No blood reaction was found on the clothes of the deceased.

Tape was used to seal the deceased's mouth, and no fingerprints were found, and no DNA outside of the deceased was found.It seems that the deceased should have worn gloves when committing the crime.The specific report will be given to you tomorrow. "Gao An replied.

The information provided by Gao An is still sparse and ordinary, and there are no new clues.

He Jiahui pondered for a few seconds, and then asked: "Gao sir, I would like to ask, the deceased was hanged in the bathroom, did you take a sample of the floor drain in the bathroom?"

"You judged the murderer's personal information through the hair NDA in the floor drain, right?"

Gao An smiled, and said, "He sir, don't look at me as young, but I am also a professional forensic witness. For such an important place as the floor drain, of course we need to collect samples.

In the floor drain, I did collect hair that did not belong to the deceased, and it was more than one.

However, considering that the location of the crime is a B&B, there are often different guests living there, and it is normal for different people's hair to appear in the bathroom floor drain.

If you can find every guest who lives in that room and take their biological samples, I can do a DNA comparison, but it may not be able to determine the identity of the murderer. "

"Indeed." He Jiahui nodded helplessly, and then continued: "The only clue left is the bundle of ropes I brought."

Two hours later, Gao An completed the inspection of the rope.

"I have tested the rope you brought. It is a polyethylene rope. The material and fiber thickness are exactly the same as the rope used by the murderer. The degree of corrosion of the material is also the same. It can be determined that it comes from the same rope.

But I have compared the cuts on the rope, and it does not match the rope used to bind and hang Zheng Jiazhen. That is to say, although it is the same rope, the murderer did not cut it directly from the rope you brought.I don't know if this information will help you. "Gao An introduced.

"Thank you, this is very useful. Now we have at least one clue, and we have a new direction for investigation. We can locate the suspect from the source of the rope." He Jiahui said.

Gao An continued: "Although I can't give you the complete forensic report yet, I will send part of the report I have completed to your mobile phone this afternoon, hoping to help you catch the murderer as soon as possible."

……

After returning to the Changzhou Island Police Station, He Jiahui immediately interrogated the cameraman Cai Mulin.

"Sir, I've said everything I need to say, what else do you want to ask?" Cai Mulin looked a little impatient knowing that he was about to be sued.

He Jiahui said, "Cai Mulin, if you don't want to be charged with murder again, you'd better cooperate with our investigation honestly."

"Okay, I'll cooperate honestly, what do you want to ask?" Cai Mulin said with some reluctance.

"Where did that rope in your suitcase come from?" He Jiahui asked.

Cai Mulin explained: "The rope is used to hang the wire. When shooting, there will inevitably be some special angles. At this time, the rope is needed.

Sometimes the actors are hoisted up, and sometimes we cameramen are also hoisted up in order to find a better shooting angle.In addition, if you need to temporarily bind and drag something, you will also use the rope.

This kind of rope is not a controlled product. It is durable and corrosion-resistant. It has a wide range of uses and is easy to buy.In addition to professional hardware stores, rock climbing equipment stores and yacht clubs can also buy them. "

"Then where did you buy that rope? When did you buy it?" He Jiahui asked again.

"I bought my rope from a tool store in Sham Shui Po, which specializes in tools related to working at heights. As for the time to buy it."

Cai Mulin frowned and thought for a while: "It must have been a long time, but I can't remember the details. It must have been more than a year! I don't go to places with harsh conditions, and the rope won't suffer too much wear and tear. This rope can be used for several years."

Bought the rope more than a year ago, so long ago that the seller is unlikely to remember who else bought this kind of rope at that time.

But He Jiahui thought about it again, the murderer used the same rope, which means that the murderer had the opportunity to touch this rope.

So He Jiahui asked, "Aside from you, who else can touch this rope?"

Cai Mulin recalled it for a few seconds, and answered: "When shooting, I usually take this rope to the scene and put it together with other tools. The director, actors, assistants, and crew members should all have access to it."

"So, the suspect is still in the commercial crew. But the problem is that each of them has an alibi!"

He Jiahui frowned, and he began to review everyone's alibi, trying to find loopholes in it.

Director Xue Chaohui's alibi was to steal money, and he was able to truthfully describe the process of the theft and take out the stolen money.And only he knew that Brother Qiang locked the money in the drawer that night, and this alibi was reasonable.

But no one witnessed him stealing the money. If he had an accomplice, he could find an accomplice to steal the money, and then kill the deceased himself.So Xue Zhaohui's alibi still had loopholes.

Photographer Cai Mulin's alibi was a tryst with a girl, and this alibi has definite witnesses, and in order to provide this alibi, Cai Mulin violated another law and was sentenced to imprisonment.So this alibi is no problem.

From another point of view, if Cai Mulin is the murderer, there is no need for him to keep the bundle of ropes. The rope is the murder weapon, and throwing it directly into the sea will leave no clues.

The actor Zhang Shaoyu's alibi is to go to a private meeting with his first love, and this alibi also has conclusive witnesses.However, considering that the person who testified had a close relationship with Zhang Shaoyu, the possibility of perjury by the witness in order to help Zhang Shaoyu cannot be ruled out.

And assistant Chen Weiting's alibi is the least problematic.He went to Macau and had no time to commit crimes.

There are not only written records on the entry and exit side of this point, but also videos, which clearly captured Chen Weiting's entry and exit.Unless Chen Weiting has a similar-looking twin brother who pretends to be him and goes to Macau to cheat the immigration office.

Thinking of this, He Jiahui opened his mouth and said: "Jing Bao, you go and check the relatives of the assistant Chen Weiting, and make sure if he has twins."

After a while, Liangbao responded; "I checked, and Chen Weiting does not have twin brothers."

He Jiahui shook his head helplessly: "Xiaohe, let's go to the scene again and do a reenactment of the case to see if any details were missed."

"I'll go too!" Licking dog Taishan once again volunteered, he didn't want He Jiahui and Du Xiaohe to have a chance to be alone.

……

He Jiahui has rich experience in handling cases. He knows that if the case is stuck in a bottleneck and cannot find a breakthrough, a better way is to return to the scene of the crime to see if there are any details that have been missed.It would be best to do a reenactment of the case again, and perhaps find new clues from it.

Returning to the homestay, He Jiahui said: "Let's reenact the case, Xiaohe, assuming you are the victim, Taishan, you are the murderer, you know each other, let's start!"

Tai Shan was very happy to play with Du Xiaohe, walked out, closed the door, knocked on the door again, and said, "Xiaohe, it's me."

Du Xiaohe immediately opened the door from the inside and let Taishan in.

"No! Xiaohe, you did something wrong." He Jiahui stopped abruptly.

"Is there any question?" Du Xiaohe asked.

"You opened the door too fast!" He Jiahui continued; "At two o'clock in the morning, even if most people don't fall asleep, they must have washed up and slept, but at this time you can't be fully dressed, at most you can wear a pajamas.

But when the deceased died, the clothes were neatly dressed, so you can't open the door for me right away, but you should get dressed first, and then open the door for me.How can it take 2 minutes? "

Du Xiaohe said, "I remember that the deceased was wearing a bra, right? Then I need to take off my pajamas, put on a bra, and then put on my coat and pants. Two minutes is not enough, at least four to five minutes."

"That's right, under normal circumstances, women will take off their bras when they sleep, but the deceased was wearing a bra, which means that she needs more time to get dressed."

He Jiahui frowned, and then shook his head self-consciously: "It's still not right! Four or five minutes is still not enough. Do you remember the face of the deceased? She cried before she died, and her eye makeup was all worn out, and the eye makeup left a long mark on her face along with the tears.

This also proves that the deceased was wearing makeup at that time, and it was not light makeup.If it was you, you must take off your makeup before going to bed, right?It is impossible to sleep with heavy makeup on.So before the deceased opened the door, he not only got dressed, but also put on makeup! "

Taishan said, "I fell asleep in the middle of the night, and I still have to get up and put on makeup again. What are you trying to do? It's not necessary!"

"It's your fault that you can't catch up with Du Xiaohe, you straight steel man!" He Jiahui thought to himself, and then he opened his mouth to explain:

"Most young women are unwilling to show others their bare makeup. These days, unless it is a family member, it is difficult for you to see young women without makeup."

Du Xiaohe said, "Although this is the case, light makeup is enough, and heavy makeup is too time-consuming. You must know that it takes a lot of time for girls to put on makeup.

It takes 10 minutes to put on that kind of heavy makeup if it is fast, and more than an hour if it is slow.If she puts on makeup after the murderer knocks on the door, wouldn't the murderer have to wait at the door for a long time? "

"After two o'clock in the morning, I also put on heavy makeup. This is also where I feel puzzled." He Jiahui said, stretched out two fingers, and continued:

"I thought of two possibilities. One is that after the murderer arrived, he really waited for the deceased to put on heavy makeup. The other is that the deceased hadn't removed his makeup at all."

"You must take off your makeup before going to bed, why didn't the deceased take off your makeup?" Du Xiaohe asked.

"Maybe she was waiting for someone, so she didn't take off her makeup. If this is the case, it means that the deceased and the murderer had an agreement in advance." He Jiahui said.

"Meet at two o'clock in the morning?" Taishan grinned, and continued; "You don't need to guess, you know what you're going to do! Could it be love killing?"

But He Jiahui shook his head: "If it's what you think, the deceased doesn't need to wear such neat clothes. It's fine to just wear pajamas, and it's easy to take off. And the result of the forensic examination shows that the deceased was not violated before his death."

This is the first step in the case repeating itself, and there are more and more doubts!
If you can't figure it out, commit it for the time being, and continue to repeat the case.

"Y-alkylbutyric acid was detected in the body of the deceased, which means that the deceased was stunned. Taishan, go and stun Xiaohe." He Jiahui said.

Tai Shan nodded and walked up to Du Xiaohe, who immediately fell down and pretended to be dizzy.

He Jiahui continued: "Then you brought rope and tape, tied Du Xiaohe's hands and feet, and put tape on his mouth. Then you went to the bathroom and hung the rope from the ceiling. Then you hung Xiaohe's neck on the rope... No, it's unreasonable."

Speaking of this, He Jiahui obviously found a new doubt.

"What's unreasonable?" Tai Shan and Du Xiaohe asked in unison.

He Jiahui explained: "Since the murderer was able to stun and tie the deceased, why did he hang the deceased to death? He had to hang the rope on the ceiling of the bathroom, and he had to hang the deceased up. What a waste of time! He obviously has a rope, so he can directly strangle the deceased to death!

Under normal circumstances, people are not directly strangled to death, but hanged to create the illusion of suicide, but in this case, the deceased's hands and feet were tied, clearly telling others that this was homicide.There is no need to pretend to be a suicide scene, so why does the murderer bother to hang people?What is his motive? "

"Maybe the murderer didn't dare to kill directly?" Du Xiaohe asked.

At this moment, He Jiahui's mobile phone suddenly rang a text message. He picked up the mobile phone and saw that it was a message from the forensic expert Gao An. He had already sent part of the forensic report to He Jiahui.

"The report from the forensic evidence, let's stop for a while, I'll take a look at the forensic report." He Jiahui said, and clicked on the forensic report.

"Huh?" In the forensic report, a piece of information caught He Jiahui's attention.

In the next second, He Jiahui said, "I may have already guessed the murderer's method!"
