"There are 49 long stick-like whipping marks all over the body. It is very likely that it was some kind of ritual, punishment, execution, etc." After working with detectives like Jiayi for a long time, Xu Junhao instinctively used reasoning.
He woke up and hurriedly reorganized his words, only narrating without reasoning:
"There are blood stains on the clothes on the shoulders, skin fragments of the deceased, wood chips, etc.... They have been handed over to colleagues in the issuance department for testing."
Xu Junhao remembered that among the series of actions that Jiayi did on the beach, there was an action of rubbing the wooden stick on the shoulders of the deceased. Obviously, Jiayi has relied on her understanding of behavioral science to infer that the murderer used her own clean cane to hit people and then wiped the cane head clean.
This is probably also the behavioral manifestation of what Yi Jiayi said, "The murderer is an arrogant person."
Thinking of this, Xu Junhao turned his head and nodded to Jiayi.
In the busy autopsy, Sir Xu only showed his intention to Yi Sha this time.
"After a thorough inspection, we found that the victim's wounds not only had incisions pointing inward, but also outward cuts."
Xu Junhao pointed to the fatal wound of the victim with his finger:
"That is to say, the murder weapon used by the murderer is not a single-edged knife, but a special weapon with blades on both sides similar to a sword.
"And, according to the autopsy of the wound, this murder weapon is very long, at least longer than half the length of the victim's neck. About 16cm or more.
"At the same time, the murder weapon is very thin, probably less than 2cm.
"As for thickness, it is thinner than an ordinary kitchen knife, less than 2mm."
Xu Junhao finished speaking, and asked a colleague to kneel on one knee. Then he took out a wooden stick that matched the shape of the long wounds on the victim's body and pretended to hit him, saying:
"If the murderer is the same height as me, then the scars on his back should be further back. If I adjust my position, the angle at which I swing the wooden stick will change, and the severity of the scars and the location of the blow will change.
"Combined with other scars on the deceased's body, the murderer must be shorter than me.
"We also found several junior sisters of different heights to do the experiment, and finally determined the murderer's height to be between 157cm and 164cm. "
Agents Wagner and others, as well as Xu Sir's assistant, were busy taking notes while nodding their heads.
Jiayi thought about it and realized that the murderer was indeed short and stocky. She only knew this information through mind flow imaging, but the forensic officer was able to make such an accurate judgment in the dark and unknown world based solely on what he had learned. This was truly admirable.
Not only did she nod her head, she also exclaimed in praise: "Xu Sir is amazing!"
Xu Junhao paused, turned his head to face Jiayi, his sword-like eyebrows raised high outside the mask: "Is your judgment the same?"
"I can't be as professional and accurate as Xu Sir. "Jiayi said sincerely.
In Xu Junhao's view, Yi Jiayi was a genius recognized by many superiors, but at this moment she expressed her recognition and respect to him so humbly, which immediately made him overjoyed.
With his eyes slightly bent, he introduced in more detail:
"Mr. Chen from the Forensic Department and I have done a murder weapon screening together. We used tea knives, double-edged knives purchased on the market, etc., and tested them on pork, and confirmed that none of them met the requirements.
"The murder weapon that killed the victim was very strange, and it might not be something that is used in daily life.
"It is very likely a homemade murder weapon."
"The murderer not only did not kill the victim in a fit of passion, but also premeditated murder with very thorough preparation." Sanfu raised his head and judged.
"It is likely related to the industry the murderer is engaged in. "Uncle Jiu began to think whether there were killers or gang members who had used similar weapons.
"I have asked people to inquire about medical and fishery related fields to see if there were any professional instruments that matched the shape profile of the murder weapon." Xu Junhao said to the detectives.
"Thank you for your hard work, Sir Xu." Wagner said.
"It's my job."
Jiayi pursed her lips and listened to everyone's communication and discussion, pursing her lips in silence.
The long sword inserted in the crutch was too special. Unless this dragon-headed cane was found, it would be impossible to think that the murderer had such a weapon out of thin air. Even if she knew the murder weapon information, she had to keep silent for the time being.
"Taking into account the decompression of the corpse, the state of the corpse's urination, the environment in which the body was dumped and other factors, the deceased died 3 to 5 days ago.
"The deceased's fingers are stiff, indicating that he seemed to be holding something before he died."
Xu Junhao pinched the deceased's wrist again and showed them the position of his left thumb and index finger:
"The rigor mortis has gradually been resolved, but when the body was first discovered, it was still clearly visible.
"Look! The marks on the fingertips of the index finger and thumb are still there, indicating that he had been pinching hard when he died, causing the bruises." "
Where is the thing?" Liu Jiaming asked anxiously.
"..." Xu Junhao shook his head, "I have already dispatched personnel to search the coast where the body was dumped, looking for something that fits the shape of the marks. But the thing is too small, I'm afraid we will return empty-handed."
"Maybe it's useless information. Maybe he just grabbed something to bear the pain." Gary comforted.
"The identity of the deceased has been confirmed. "Xu Shaowei, who had just received the fax, walked into the forensic autopsy room, handed the document in his hand to Yi Jiayi, and said:
"The deceased's name is Wang Xinqiu, and everyone calls him Xinzai.
"He is a famous gangster in Yau Ma Tei. He plays cards, gambles on horses, and parades in the streets all day long. He has nothing to do. Every day he follows some street brothers to make a living, works as a broker, a lackey, and occasionally works as a rickshaw driver to help attract customers and watch the store. He does everything to make money and runs around everywhere.
"According to the time of death inferred by Sir Xu, on the day of his death he first went to participate in the village's Dajiao activities, helped with chores, and earned some extra money.
"After that, he went to play cards again, lost some money, and then went to drink tea, and stayed there until the evening. What he did after 18:00 has not yet been found out."
"Brother Jiaming, Brother Gary, use some informants to check the social relations of the deceased Wang Qiuxin, what he did around December 2, who were the witnesses, who he had quarrels with, who he had financial dealings with, and other unusual relationships." Jiayi made a note in the notebook and raised her head to give instructions.
"OK, madam." Liu Jiaming and Gary responded in unison, and then turned around and left one by one.
Seeing that the detectives treated this young female inspector with such respect and obedience, the brothers in the forensic department could not help but look Yi Jiayi up and down again.
Over the past six months, this young female agent has undergone tremendous changes, like a chubby insect that has escaped from a cocoon and transformed into a butterfly that can fly on the wind.
Jiayi gave the order and did not notice the other people's eyes looking at her.
She was still worried about the bruises on the fingers of the deceased that Xu Junhao had just mentioned. She took a deep breath, held the notebook and pen, and walked towards the body that had been dissected and sewn back together. Her eyes passed over his arm and fell on the two fingers.
The next moment, she was pulled into the flow image again.
The environment where the deceased was in seemed to be a huge factory. The light shone from in front of the deceased. Although it was very bright, it could not illuminate his hands tied behind his back.
Jiayi had to watch the flow image from the beginning to the end, and then watched it repeatedly. It was not until the third time that she vaguely made some guesses based on the degree to which the sleeve of the deceased's left arm was tightened.
A small round mark, could it be the cufflink of the shirt he was wearing when he died?
Jiayi took a deep breath and pulled her mind out of the flow image. She turned around and saw the forensic officer discussing the identity of the deceased with other detectives, trying to extract some useful information from the autopsy results of the corpse.
Only Xu Shaowei stood beside her from beginning to end, ignoring the discussion of others. He just looked at her from time to time, and then looked at the fingers of the corpse that she had been staring at, guessing what she was thinking. Jiayi
said hello to Xu Junhao and others, and then took Xu Shaowei out of the autopsy room and went straight to the Forensic Office.
When she mentioned her guess to Senior Chemist Chen Guangyao, he immediately took out the shirt that the deceased was wearing when he died, which the forensic officer sent over.
The laboratory technicians have already tested the bloodstains and sawdust on the shirt and confirmed that the bloodstains and dandruff on the deceased belonged to the deceased. The sawdust was consistent with the sawdust extracted from the deceased's mouth. It was initially determined that it fell from the stick-like object used to beat the deceased.
After turning out the deceased's shirt, Chen Guangyao picked up the left sleeve mentioned by Jiayi and found that there was indeed a small button there.
After Diane scanned the shape and size of the button, she immediately faxed it to the forensic officer, asking him to judge whether the button was consistent with the bruise on the deceased's finger.
Chen Guangyao carefully cut off the button and took it to the laboratory table for microscope observation and extraction of tiny physical evidence.
There was nothing on the button except the blood, skin flakes and dust of the deceased. He pondered for a while before taking the thin blade handed to him by junior laboratory technician Ajie and gently peeling off the plastic button.
However, he found that the button was not solid inside. It was like a small round container with many transparent small particles like rock sugar hidden in the hollow.
Chen Guangyao looked up in astonishment and briefly exchanged his surprise with Jiayi. He then arranged for the chemical group's evidence inspection room to test the particles extracted from the button.
In a short while, the chemist gave the conclusion:
"It is a new drug that invaded our country at the beginning of this year, solid methamphetamine, which is called 'happy ice', 'power pill', 'diamond', 'crackling' and 'toothpick' by drug dealers, commonly known as 'ice'."
Chen Guangyao frowned, and his face gradually became solemn after he handed over the report.
He turned his head and explained to Jiayi and Xu Shaowei in a deep voice:
"This is methamphetamine hydrochloride that was accidentally produced by Japanese drug dealers in the mid-1970s when they replaced sulfuric acid with hydrochloric acid for solid processing. It first appeared in Hong Kong at the beginning of this year. Although it has just entered the market, it has a great trend of replacing 'Hong Kong stone' (heroin).
"The police first discovered this thing at the beginning of the year during a crackdown in Causeway Bay. Although some people say that this thing has spread to the whole of Hong Kong through underground sales, it has not been caught in Yau Ma Tei so far... Although the content in this button is small, it is also the first case in Yau Ma Tei.
"O Ji has urgently set up several special task forces at the beginning of the year to eliminate all underground distribution gangs of this product, but has not reported even one successful mission."
"..." Jiayi listened to Chen Guangyao's words, her expression became more and more solemn, her lips gradually formed a straight line, and there was no trace of tenderness between her eyebrows.
"I understand, Brother Da Guangming! Thank you for your hard work." Jiayi nodded, turned around and said to Xu Shaowei:
"Call Sir Xu immediately to test whether there are any "ice" residues in the body of the deceased Wang Xinqiu!
"Call all the detectives who are still in the Forensic Department to return to the office! "
After saying that, she left Xu Shaowei behind and turned around to walk away from the Forensic Science Department. She was like a gust of wind, and she hurried away.
In the early 1990s, ice invaded Hong Kong, Fujian, and Guangdong. It is far more brutal than any serial killer!
The horn of this anti-drug war has just sounded, the situation is critical, and the police need to fight a good battle.
