The morning light gradually deepened. Being in the middle of a murder case, she experienced the strongest evil in the world, the fiercest anger. How could she keep her heart from falling into the abyss?

A murder case teaches you the most terrible evil thoughts. How could you use kindness and optimism to understand the world?

She closed her eyes, took a deep breath, clenched her fist and opened it again

. She didn't have a dagger in her hand at that time, and there was no life passing away in front of her.

There was only a sudden slap on her shoulder. Wow, Brother Yue was really strong. These tough guys were used to slapping each other. They were all strong and sturdy. Of course, they had to slap their backs and shoulders very hard to have a stimulating effect.

She was made of flesh.

Rubbing her shoulders, she followed Brother Yue to the sofa inside that the murderer had not touched and rested for a while.

Fang Zhenyue told her that her face was still a little pale, and he was not in a hurry to ask her what she found. He stood quietly beside the sofa, watching the colleagues from the forensic department investigate while waiting for her emotions to recover and her body temperature to rise.

Jiayi seemed to be observing the work of her colleagues from the forensic department, but her mind was trying to recall everything she saw in the mind flow image just now.

[Drawing of the murderer]

When the murderer stood next to the hostess, it can be seen that he was shorter than the hostess. So after Sir Xu gave the height of the hostess, she could use this to judge the height of the murderer.

The murderer was wearing a raincoat, shoe covers on her shoes, and rubber gloves on her hands. These things must have been put in her pocket when she left. If the things had been burned by her, is it possible that there were still bloodstains and clues left in the pocket of the clothes the murderer wore that day - the pocket that had contained the raincoat and other things?

This is a direction to find evidence, but it can only be done after the murderer is found.

So how to find the murderer?

Judging from the reactions of the victims, no one in this family knows the woman.

Could it be someone the male owner knows? The mistress turned from love to hate and came to the cheating man's house to kill the original wife and her family?

Then we have to start with the only surviving male owner.

But now everyone doesn't know that the murderer is a woman. Only she knows the murderer's gender because she has seen the heart flow image.

Judging from the current situation, the whole family has been killed, and only the male owner is alive... Jiayi pursed her lips. Even if she asked the detectives to investigate the male owner, it is estimated that the detectives will definitely pretend that the male owner is the murderer.

So now we have to start thinking of a way to use the forensic department and Mr. Xu to say that "the murderer is a woman."

How to do it?

The footprints and palm prints of the forensic department, even if the murderer is wearing gloves and shoe covers, the fingerprints and sole prints cannot be seen, but the size can be judged.

In addition, Mr. Xu, the medical examiner, may be able to infer the force of the murderer's slashing and stabbing through the wounds on the body of the deceased, and then judge that this is the strength of a woman. In addition,

Mr. Xu can judge the approximate height of the murderer from the angle of the murderer's chopping and stabbing. Mr. Xu has used this method to judge the height of the murderer in other cases before, such as the height of the murderer Lu Weiye in the "Kneeling Corpse Case" was very accurate.

Then the detectives can judge based on this height. Unless there are special circumstances, the murderer is either a woman of average height or a man shorter than other men - as long as the male owner of this house is not a short man, at least the detectives can preliminarily judge that the direct murderer is not the male owner.

After thinking for a while, Jiayi rubbed her forehead and narrowed her eyes slightly.

"Gary went to buy coffee. You should drink some hot coffee and sugar to warm your stomach before you start working." His voice was deep. Thinking back to the look she saw when he came in just now, he was still a little worried.

When she was recruited into the team before, she didn't see that she was the kind of workaholic who would risk her life for work.

"I'm much better, Brother Yue." Jiayi stood up and took another sip of the hot water he had just handed over before saying, "What do you think, Brother Yue?"

Fang Zhenyue carefully examined her face and confirmed that she seemed to have almost recovered. Then he said, "No money was lost at home, and there were no signs of the murderer rummaging through the drawers."

"Yes." Jiayi nodded and immediately realized that because she saw the flow image, she directly confirmed the murderer's clear purpose of killing people. She only thought about how to catch the murderer, but forgot the normal logical order of investigating the case.

These days, because of their trust in her, the detectives of Group B followed her pace in everything, but ignored the options that should have been carefully ruled out.

Deduction is a method she must use based on the flow image. But the inductive method of case investigation is a practical skill that she must constantly strengthen and must not neglect to learn.

She took out her notebook and her face instantly became serious. She carefully recorded Brother Yue's thoughts and used this to draw wavy lines under the notes. Then she responded:

"Basically, the motive of burglary is ruled out."

Fang Zhenyue suddenly looked high-spirited, and the corners of her lips raised slightly.

The female sergeant returned to her battlefield with the enthusiasm that she seemed to never need.

...

Jiayi communicated with Brother Da Guangming and Diane from the Forensic Department and confirmed the size of the shoe cover mark left by the murderer after stepping on the bloodstain.

"Probably size 36, this size is considered small even for women. Unless the murderer stepped on another pair of shoes that were not in line with the feet to kill, the possibility of it being a man is very low." Diane stared at the bloody footprints for a while, turned to Jiayi and said:

"Looking at the force of the footprints, it is consistent with the marks left when walking with normal shoes and shoe covers. Look at the toes, soles and heels, there should be a pair of ordinary sports shoes inside the shoe covers."

"The palm print is also small." Ajie just collected half of the bloody handprint left when the murderer pushed open the glass door of the kitchen. After restoring it in his brain, he compared it with his own palm and found that it was much smaller than his hand.

Sir Xu had already done a rough examination of the four bodies. When taking the bodies away, Jiayi came to ask Sir Xu a few questions.

Based on the locations of the wounds on the four bodies and the angles observed with the naked eye, Xu Junhao made a judgment, "Based on the current clues, the height of the deceased is approximately between 156cm and 162cm, and should not be taller. Moreover, I initially inferred that the deceased was shorter than the hostess. The hostess is a little shorter when standing than when lying down, so her standing height is probably around 165cm, and the murderer is most likely 159cm tall."

"Sir Xu is amazing." Jiayi saw the murderer, but Sir Xu did not. Yet, he was able to estimate the height difference between the murderer and the deceased so accurately. He is a true professional!

"It's just basic knowledge." Xu Sir unconsciously wanted to touch his hair again. He put his hands on his head and remembered that he was still wearing gloves. He quickly dropped his hands. How could he open his screen again? He couldn't get carried away in the workplace.

He cleared his throat, regained his serious state, and asked Jiayi seriously:

"Any other questions?"

"No, for now. Sir, please give me the autopsy report as soon as possible!" Jiayi nodded politely.

"Sure." Xu Junhao nodded in return, turned around and called his assistants and uniformed police to carry the body back to the office.

Jiayi gathered several accurate scientific clues and said to Fang Zhenyue and the detectives from Team B:

"The murderer is most likely a woman who is about 159cm tall, not very tall."

"Brother Sanfu, take Jiaming to talk to the old man and ask him if there were any women of this height who visited the time of death that Mr. Xu just preliminarily estimated was 'between 17:00 and 20:00 yesterday'. If so, what was the reason for her visit, how was she dressed, what did she look like, and whether the old man could cooperate with the police to draw a portrait of the murderer." Jiayi turned her head and glanced at the detectives from Team B, and in the blink of an eye, she arranged the detectives clearly:

"Uncle Jiu, take Shaowei to visit the residents and renovation workers upstairs and downstairs to see if there are any female people who meet this height, and then ask them if they have seen people with facial features similar to the murderer during the time of the victims' death."

As soon as the state recovered, the work began to move forward.

Fang Zhenyue stood in the house with his arms folded, looking at the scene and thinking, while paying attention to Jiayi from time to time.

Watching her arrange the work with great force, there was a comfortable pleasure in his heart.

That kind of rhythm of the big knife and axe forward is really comfortable.

Fang Zhenyue and Jiayi followed the colleagues of the Forensic Department to conduct another on-site investigation, and guessed the murderer's movement, movements, and behavior sequence at the time of the crime based on the clues at the scene, and deduced the murderer's thoughts.

"Based on Mr. Xu's rough inspection and the results of our on-site investigation, we can basically confirm..." Diane used white chalk to write '1' outside the outline of the Filipino maid's body drawn by Ajie, and wrote '2' outside the outline of the mistress's body. As she wrote, she continued:

"The Filipino maid was killed as soon as the door was opened. There was no struggle, and everything happened very quickly. Doesn't it mean that the murderer had almost no hesitation in killing people?" "

The murderer came here for the purpose of killing people. The motive for killing was not generated at the scene, but had existed long ago." Jiayi immediately judged:

"There was a grudge long ago.

"But who among them did the murderer have a grudge against? He killed the maid without hesitation, and then killed the mistress immediately..."

Diane looked up and exchanged glances with Jiayi for a few moments, then looked towards the stroller and the kitchen, then walked towards the stroller, wrote the number '3' on the ground next to the stroller, and continued:

"There was a small amount of the maid's B-type blood on the mistress's clothes, and the bloodstain analysis also verified our speculation. The third victim can be judged by the same logic, and it is undoubtedly the baby.

"It's impossible that the baby also has a grudge against the murderer."

"The motive for the murder..." Jiayi frowned. If the murderer was really the mistress of the male owner, then perhaps it would make sense.

If the love rival's original wife was to be killed, the original wife's son would naturally not be spared, and the original wife's mother would definitely not be spared either.

It happened that Gary came back with two big bags of coffee. He had calculated the amount of coffee before leaving, but when he stood at the door of the crime scene, he found that the colleagues from the forensic department who were supposed to wait for coffee had already left, and even Uncle Jiu and four others from Group B had disappeared.

He looked up and met Jiayi's eyes, then raised the bag in his hand, motioning everyone to take a break and come out to drink some coffee to replenish their blood.

But before he could speak, Yi Jiayi took the lead and said:

"Brother Gary, go back to the police station and check the file of the male owner to see if he has a criminal record. By the way, before going back to the police station, go to the property management to get the information about the male owner's work unit and other information. Oh, and collect statements from the property management staff to understand the relationship between the couple and whether there is any gossip or something like that."

Gary held up the coffee, looking confused.

How come I suddenly received 10,000 tasks?
