When Liu Jiaming was sent by Jiayi to the various gates of the community to call back the two uniformed police officers and Xu Shaowei, Guangming, a forensic scientist, also arrived with Diane, a mid-level chemist, and Ajie, a junior chemist.
All the customers who had eaten in the ice house were taken to the police car to wait for their statements. The uniformed police cordoned off the Xianji Ice House. The media, who had the most sensitive noses, also rushed to the scene and stood outside the cordon to look around, trying to capture some explosive photos, at least to find out what happened in Xianji Ice House -
did someone die? Or was it some other type of vicious incident?
The cordon separated the distance long enough to ensure that the media and citizens could neither see the situation inside the ice house nor hear any noise inside.
The uniformed police officers stood guard at their posts and strictly prohibited all unrelated people from approaching.
Xian Ji Ice House became a peaceful and undisturbed place. Several tables in the front hall were still filled with half-eaten or unopened food, but now it was all cold and the appearance of the food could no longer arouse appetite.
Da Guangming looked around blankly, and even when he stood at the kitchen door and looked inside, he did not find his target.
There was no corpse here, nor any traces of a fight between the murderers. He did not understand where the crime scene that Wagner mentioned on the phone was, with complicated clues and high difficulty in exploration.
Wagner noticed Da Guangming's gaze, but he did not look back at him. He only kept his eyes on Jia Yi's face, waiting for the youngest female sergeant in Hong Kong to give him an answer.
Brother Da Guangming followed W Sir's gaze and looked at Jiayi, raising his eyebrows and looking even more puzzled.
Jiayi felt everyone's gaze and turned to look at the barbecued pork buns on their table that had not been touched.
At the moment when she slammed the table and questioned the suspect, she only thought about not letting her teammates really eat the meat.
The suspect's guilty escape of dropping the plate and resisting arrest with a chopping knife gave her confidence. On the way to catch him, she was fully focused on how to catch him. It was not until Brother Sanfu took the suspect away and turned back that she finally had time to think about how to deal with the next questioning.
Facing everyone's puzzled looks, she took a deep breath, walked to the table, picked up a barbecued pork bun, tore open the dough, pointed at the barbecued pork inside, glanced at Wagner and asked Brother Da Guangming:
"Brother Da Guangming, can you tell what kind of meat this is by looking at the cooked meat?" Brother
Da Guangming walked over to take the barbecued pork bun, looked inside, then looked up and looked at the other agents, then answered hesitantly:
"You can tell that this is not beef, nor chicken, nor duck or pigeon meat."
He handed it to his nose and sniffed it, and then said:
"The sauce is too strong. I can only smell sweetness and oyster sauce. Even if it's mutton, its unique smell is gone... Is it the meat of some small or medium-sized animal?"
After saying this, he met Jiayi's eyes, and a question suddenly emerged in his mind: Why did Jiayi ask this question? Now they are all at the so-called "murder scene", so this meat...
His face sank, even the experienced senior laboratory technician stared with an expression of disbelief at this moment.
Jiayi nodded, showing the meat in the barbecued pork bun to everyone, and then said:
"Even if you don't run an ice cream parlor at home, and even if you are not a senior chef, you can tell that beef has thicker shreds and red meat. If it is not overcooked, most adults can basically tell the difference between pork, mutton, chicken, beef, etc. by looking, smelling and tasting.
"Beef is slightly sour, pork is slightly smelly, mutton is smelly, and chicken is very fishy... and the fatter the meat, the stronger its original pungent smell.
"My family runs an ice cream parlor, and I followed my eldest brother to buy meat and process ingredients a long time ago. Soaking the meat in water to remove the blood can reduce the pungent smell of the meat and change the color of the meat.
"How to remove acid from beef, and what is the difference in taste before and after deacidification.
“How to deodorize each type of meat? Cooking wine, peppercorns, star anise, dried orange peel, etc. can all be used, as well as blanching. But after deodorization, the meat will definitely retain the flavor of the seasoning: it is best to use five-white herbs to deodorize mutton, so that instead of the mutton smell, you will taste white pepper, angelica and other seasonings when you eat it; cooking wine, peppercorns, star anise, bay leaves, ginger, etc. are used for pork; green peppers, ginger, black pepper, etc. may be used for beef… No matter what the chef uses, it will eventually leave traces, and anyone who has been in the kitchen for many years can judge what ingredients were used through these traces, and then may be able to deduce what kind of meat you are eating.
“Although I’m not a chef, I can generally be considered such a person. Over the years, I am very familiar with the color of each type of meat, the thickness of the meat, the softness of the meat, the subtle differences in smell, the thickness of the skin, etc. "
After saying that, she took a deep breath and said with difficulty:
"Brother Da Guangming is right, this is not beef, nor is it chicken, duck or pigeon meat.
"The menu of Xian Ji Barbecued Pork Buns says that it is made of pork, but I learned to make pork barbecued pork buns with my eldest brother, and I know that pork barbecued pork is not like this.
"At first I was just wondering what kind of meat was used, thinking that the new boss was just unscrupulously using bad meat to pass off as good meat and other meat as pork.
"But when I asked him, he ran away in a panic, obviously feeling guilty.
"You can think about it, if it was just a matter of mixing other meats, would you be so scared that you would abandon the store, abandon the plate, and run away with the weapon?"
You know, if a person resists arrest with a weapon, the police can shoot him.
"No." Gary answered truthfully after thinking deeply, "So there must be something big wrong with Xian Ji's new boss. "
Jia Yi nodded.
Xu Shaowei, who was standing next to Jia Yi, suddenly frowned. He keenly understood what Jia Yi had not said, and took a step back unconsciously. His right hand supported his left elbow, and his left hand was clenched into a fist and pressed on his lips.
Xu Shaowei didn't want to look at the barbecued pork buns any longer. He lowered his eyes and sniffed the familiar soap scent between his fingers, suppressing the discomfort that was gradually rising in his stomach.
"Of course, if I just suspected that there was something wrong with the meat in the barbecued pork buns, I might question it, but I probably wouldn't be so severe.
"There is a reason why my attitude is particularly fierce.
"Think back, when we just sat down to order, Inspector Wagner asked about the whereabouts of the original owners of Xian Ji Ice House, Da Jiao Qiang and his wife. At that time, the suspect replied that Da Jiao Qiang was his master and had immigrated with his family. "
Jiayi finished speaking and looked at Wagner for confirmation.
Wagner nodded, but his brows were still furrowed.
Before coming to Team B, Superintendent Wong had mentioned this new female sergeant to him. The police force is not sticking to one method to recruit talents, and there are very sufficient reasons to promote a young female police officer who has made outstanding achievements to be a sergeant.
Superintendent Wong asked him to explore the reason himself.
He was ready to observe the peculiarity of Detective Yi Jiayi carefully, but he didn't expect her "eccentricity" to be revealed so early.
It was only his first day at the Serious Crime Unit, and she gave him a head full of questions and curiosity.
"And then?" Liu Jiaming couldn't help but continue to ask. He was also there at the time and didn't think there was any problem.
Is there something wrong with the answer of the new boss of Xian Ji?
Jiayi turned to Liu Jiaming and wanted to give a smile. The corners of her lips curled up, but she turned it down as if she had her own ideas.
She pursed her lips and suddenly pointed at Xu Shaowei.
Everyone's eyes turned to the new detective of Group B standing outside the crowd.
Xu Shaowei suddenly became the center of everyone's sight. A layer of chicken skin instantly exploded on his body, and his hair stood up.
He was really not a person used to being stared at. After scanning the others with his eyes, he choked awkwardly and looked at Yi Jiayi with a slow heartbeat.
"When Shaowei heard what I said before, he had his own speculation. So he took a step back and held the elbow of his other arm with one hand. This action is similar to wrapping his arms around his chest, and it actually means protecting himself.
"On the other hand, Shaowei pressed his left fist on his lips, which actually reflects his disgust and disgust. Lowering your eyes, pressing your lips with your fists, and holding your nose are actually behaviors to avoid and protect yourself.
"Agent Xu Shaowei, am I right?"
The goose bumps on Xu Shaowei's arms subsided quietly. He lowered his hands awkwardly and put them in his trouser pockets. Then he coughed lightly and nodded:
"That's it."
Brother Daguangming has never watched Jiayi analyze something so completely. His upper body unconsciously leaned forward slightly because of interest. I heard that Jiayi's reasoning is very exciting, and now it seems that it is true.
Jiayi's analysis of Xu Shaowei's body language was correct, but then what?
What does this have to do with the suspect?
Jiayi nodded to Xu Shaowei, turned her head to meet Wagner's eyes which were slightly narrowed due to thinking, and slowly revealed the secret:
"When Xian Ji's new boss answered Inspector Wagner, I habitually observed his reaction.
"His eyes flickered, and when I looked directly at him, he instinctively avoided my sight and did not look at Inspector Wagner.
"At the same time, his shoulders unconsciously shrugged slightly and shrank inward, which is a physical movement caused by nervousness.
"And, after answering Inspector Wagner, he tilted his head and rubbed his ears."
Jiayi rubbed her ears and asked softly:
"Did everyone pay attention to these reactions of this person?"
"..." Liu Jiaming looked bewildered. He had almost forgotten what the new boss of Xianji looked like. He seemed to have a square face and a broad body, big eyes and double eyelids, a fleshy nose and thick lips, and he looked very honest.
When Wagner asked questions, the new boss answered them in a split second.
Did the Eleventh Sister pay attention to so much information?
He frowned and finally understood the gap between himself and Yi Shazhan.
Uncle Nine and others He also chose to remain silent at this moment. Only people like Inspector Wagner knew how to hide his emotions better than Liu Jiaming and did not reveal his confusion.
Jiayi looked around and judged from everyone's silent reaction: No one present noticed what little movements the murderer really made at the time.
In other words, even if what she said was inaccurate or fabricated, no one could find it.
Quietly breathing a sigh of relief, Jiayi continued:
"If the forensic officer Xu Sir was here, he might help me explain this behavior.
“The human ears, noses and other parts have abundant capillaries. When we are under stress, we will instinctively touch these places to regulate hormone levels and relieve stress...
“A few days ago, I discussed criminal psychology and behavior with Inspector Tannen, who was specially hired by the police station from a British university. Among them, there are methods of observing details such as body language and facial expressions that are used during interrogations.
“Because I just talked to expert T recently and read a lot of books on this topic, I am very sure that the new owner of Xian Ji Ice House was very uneasy and nervous when answering W Sir.
“In response to the answer of the former owner of Xian Ji, Da Jiao Qiang, he was lying. "
After these words came out, the police officers who were staring at Jiayi and listening to her analysis were all drawn into her discourse system.
Some of them felt that this knowledge was unfathomable and that Jiayi was amazing; some of them were completely confused and had no ability to refute anything.
The whole audience fell to the ground and gave Jiayi a convinced look.
