Xia Dong took two mouthfuls of rice, looked up and was about to say something to Ye Fan, when he saw a flower in front of him, there was no Ye Fan in the position, and he only moved a bite of the boxed lunch.

Hua Ming and Xiao Fang were also taken aback when they spoke, blinked their eyes, and were a little frightened: "Ye, Ye...... What is this?" I really didn't have the courage to call her by her name or Ye Xuemei in front of my seniors, so I could only pass by vaguely.

After Xia Dongzheng was stunned for a while, he quickly took two mouthfuls very calmly and said, "It's okay, Ye Fan should have thought of the breakthrough point of the case." After saying that, he also got up and walked out of the office, and only ate a few bites of the boxed lunch on the desk.

Xiao Fang patted the shoulder of Hua Ming, who was still with his mouth open, and said with a smile: "It's good to get used to it, everyone who does criminal investigation is like this, so ah, when you have free time to eat, you have to eat quickly, and you can't tell when you come to the case." ”

Xia Dong closed his mouth and asked the question that he had been holding in his heart since Fang Cai: "Brother Fang, Ye, Ye Fan, she is also the forensic doctor in the team, you all call her a consultant?" Also, what case did she think of? The deceased who died in the car accident just now?

Ah, he's really full of questions right now.

"Hey, a few months ago, the serial decapitation murder case that caused a sensation across the country, do you know?" As soon as Ye Fan was mentioned, Xiao Fang was excited, and directly pulled a chair to sit next to him, and several other forensic colleagues who stayed to work overtime also temporarily put down their work and surrounded them.

Hua Ming nodded inexplicably, that case was so sensational, how could he not know that Dean Yue also used one of the deceased, Cai Qianqian, as a case to give a lecture to several graduate students who were preparing to engage in criminal investigation and forensics, but wasn't he talking about Ye Fan, why did he suddenly mention the case a few months ago.

Suddenly, a light bulb on his head lit up, Hua Ming fell from the chair in shock, sat on the ground, his eyes widened, and his lips trembled for a long time before he found his voice: "Consultant Ye! The mysterious Consultant Ye in the serial decapitation murder case is Ye Fan?"

The stimulation this time was much greater than seeing Ye Fan's true face just now, and he couldn't even scream out of the groove.

It's not that he forgot that there is such a person as Consultant Ye, but he doesn't dare to associate Consultant Ye Fan with Consultant Ye of the serial decapitation murder case.

Ye Fan, is that Ye Consultant?

oh，no！

"yes. Xiao Fang and several forensic classmates grinned, revealing a mouthful of big white teeth.

Hua Ming rolled his eyes, fell back, and fainted gorgeously.

Later, someone asked him how he felt about his first day of internship in the Criminal Investigation Brigade, and he also grinned and shouted: Exciting!

Completely unaware that his small vest frightened poor Hua Ming, Ye Fan didn't care about eating, and rushed into the office of the technical department, which was also brightly lit overtime.

"Consultant Ye?" A technical police officer was standing in front of a large rectangular table with a broken porcelain plate, looked up and saw Ye Fan rushing in, without her questioning, he pointed to a room and said, "Team Leader Qian is inside." ”

"Thank you. Ye Fan bowed his head and walked over quickly, looking inside through the glass on the door, Qian Qian was operating a machine to do inspection work.

Even if he was in a hurry, Ye Fan didn't knock on the door immediately, but stood patiently at the door and waited, while his brain was spinning, thinking about a point of inspiration that had just been touched.

Qian Qian's inspection work quickly came to a paragraph, and Ye Fan knocked on the door rhythmically.

Hearing the knock on the door, Qian Qian frowned, feeling unhappy that he was disturbed, took off the equipment, walked over with a calm face and opened the door in two steps, and saw that it was Ye Fan standing outside, his calm face instantly became gentle and amiable, and he said in surprise: "Ye Fan, why are you?"

"Qian Qian, are you done?"

"Is there a new discovery in the murder case?" Qian Qian nodded and asked quickly, his first reaction was the same as Xia Dong's.

Ye Fan nodded and asked, "Didn't you take some sand and gravel from the glass window slot at the scene of the crime that day?"

There is not much physical evidence collected at the scene of the murder and murder, especially in the bathroom, and the examination that should be done is basically done.

"It's just ordinary gravel and dust. Qian Qian said, took Ye Fan to his office, took out a report and handed it to her, although it looked like ordinary sand, but in line with the principle of not letting go of the slightest prudence, the technical team still did the test and analyzed the ingredients.

Ye Fan looked at the component analysis on the report, and didn't fully understand it, after all, there was a specialization in the art industry, but she could still understand the later conclusions.

"There are traces of humus in the gravel dust?" Ye Fan's brows moved, and he was already fifty percent sure of the guess in his heart.

Qian Qianyi nodded, although this report was not made by him, but he had seen that the main component of sand and gravel dust was silica, which was stained with extremely trace amounts of humus, and the apartment building was a green belt, which was normal.

At this time, Xia Dong happened to come in, and when he saw the two of them looking at a report, he asked, "Is it the murder case that found something suspicious?"

Ye Fan handed him the report and said, "I think, I know how the murderer entered the deceased's bathroom. ”

"How did you get in? It has something to do with these gravel dusters?" Xia Dong and Qian Qian immediately asked, how the murderer climbed into a sealed bathroom through the outer wall was a mystery that the police had been unable to solve.

Ye Fan nodded: "If my inference is correct, the murderer directly pushed open the window and entered the bathroom." Before Xia Dong and Qian Qian frowned and wanted to wonder, they added: "Because the windows were not locked at that time." ”

"How is this possible, you also said before, it is winter, and the temperature has dropped sharply around New Year's Day, if the bathroom window is open, the howling cold wind can freeze people into popsicles, how can Li Lanke not close the window, and if the sliding window is closed tightly, it will lock it by itself. Qian Qian shook his head and retorted.

Xia Dong looked at the report, thinking that Ye Fan had just run out while eating, and when she made an autopsy report for the deceased in the car accident before, her thoughtful expression ......

Gravel, sand on the large intestine of the deceased in a car accident? Xiao Fang and Hua Ming talk about the difficulty of opening and closing office windows?

"I see. Xia Dong looked at Ye Fan with sparkling eyes, shook the report in his hand and said, "It is really possible that the window at the scene of the crime was not locked, because it was stuck by the sand and gravel in the window slot. ”

Qian Qian's head turned, and his eyes opened slightly: "You mean, the murderer stuck the edge of the window groove with mud in advance, and the window looked tightly closed, but in fact it was just closed, and there was still space between the glass window and the window frame, so it was not locked at all?"
