Yu Na has limited clues about the suspect. Ji Si'an looked at the time and asked another question: "Yu Na, do you think this is your bag?" ”

Yu Na looked carefully at the bag in the photo, and she seemed to be a little hesitant.

Yu Na loves bags, and often takes care of them, especially since this bag is still newly bought, so it shouldn't be so difficult to recognize.

When Ji Si'an guessed that Yu Na didn't know this bag, she said, "This is mine."

"The bag that I had put in this position was worn, and I threw it away because I didn't like it. I bought this later, and I haven't had time to use it yet. ”

Hearing this answer, Ji Si'an was a little discouraged, thinking that they had found an important clue, but the result was still in vain.

Towards the end of the meeting, Yu Na couldn't help but ask, "How is my father?" ”

"He ......" Ji Si'an thought of the old man with gray hair and a stiff body, and didn't know how to answer.

"What's wrong with him?" Yu Na was a little nervous when she saw Ji Si'an's face looking embarrassed.

"He doesn't have anything, it's just that there are a lot of things at home."

Hearing Ji Si'an say this, Yu Na was obviously relieved, that 'family' had nothing to do with her.

"Your father's house was burglarized. Your sister Yu Jia is dead. Ji Si'an still told Yu Na about the matter.

"What?!" Yu Na's face turned pale instantly.

"How did Yu Jia die?" She asked nervously.

Ji Si'an sighed, Yu Na said that she didn't care, but she was a little worried in her heart.

"Yu Jia was robbed and killed."

"How so? What a coincidence......" Yu Na left with a shocked expression on her face.

Ji Si'an looked at Yu Na's back and was silent for a long time, she recalled her eyes just now, and she clearly saw a flash of horror in it. What is Yu Na afraid of?

Ji Si'an told Luo Li about his doubts and what Yu Na said.

Luo Li boldly guessed: "Do you think these two robbers will be the same person?" ”

"The person who killed Yu Jia is skillful, both the choice of the murder weapon and the choice of the target person are quite mature, and it is definitely not the first time to commit a crime. According to Yu Na's description, the people who robbed Pan Fengxia were more flustered when they committed the crime, and their methods were more rusty, and they should not be alone. ”

"We can only hope that there are clues from the police that are beneficial to us." Luo Li said with some dejection.

Within the criminal police team, they are also considering the case that happened at Yu Na's house.

"The chances of a family being stolen and two murders at the same time are too small."

"If you want me to say, either they will be punished for their bad deeds, or they will be deliberately retaliated against for offending someone."

"At present, there is no direct relationship between these cases. The biggest suspect in Pan Fengxia's case is Yu Na, and Yu Jia's murder case has been combined with several previous robbery and murder cases......"

"Alright, don't guess, get to work." The detachment leader interrupted everyone's discussion.

Everyone dispersed in a hurry, and the detachment leader turned around to find that Yuan Mu was the only one left in the room, still in a daze at the computer.

"What are you thinking, girl?" He came behind Yuan Mu.

"Huh?" Yuan Mu came back to his senses and said: "Detachment leader, I compared the video of the scene and the autopsy several times, and found that something was wrong. ”

"What's wrong?" He sat next to Yuan Mu.

"Judging from the autopsy, in the first two robbery and homicide cases, although the murderer also hit the victim on the head from behind, the purpose was generally to rob. In Yu Jia's case, the murderer's purpose was to put her to death, and the robbery seemed to confuse us. ”

"Oh? What is the basis for such a judgment? The detachment leader picked up the autopsy report and looked at it.

"In the first two cases, although the victim was hit hard in the back of the head, he was hit 1 or 2 times, and after the victim fell to the ground, the murderer grabbed the bag and fled. But in Yu Na's case, if you look at this picture of her after being hit in the back of the head, the medical examiner's report says that she was hit at least 5 to 6 times, and from the wounds, the next few blows were caused by her falling to the ground...... In other words, even though she had lost the ability to resist, the murderer still hit her in the back of the head many times until she died. The murderer seems to want her to die more than robbery. ”

"Well, this is indeed suspicious, but it cannot rule out the possibility of the murderer's crime escalating. Anything else? ”

Yuan Mu called up the video: "You look at these two videos, although you can't see the specific appearance of the murderer because of the distance and resolution, you can see the stride and posture of their walking." ”

"The murderer in Yu Jia's case has a larger stride and a faster frequency than in the previous two cases. And this...... You see, the murderer seems to have a gesture of raising his hand. I pondered for a long time and thought it was a hair-pulling action. I'll show you, you don't look like it. ”

Saying that, Yuan Mu found a baseball cap and put it on her head, she turned her body sideways and used her right hand to pinch the hair on her sideburns back as she went. "Do you look like that?"

"Well, it's like that." The detachment leader almost stuck his head in the screen and carefully looked at the image. "This action is a subconscious action, but the video time behind it is too short, so it's hard to be sure that he doesn't have this action."

"I've thought about that too." Yuan Mu took off his hat and continued: "You see, although my hair is short among girls, the hair on my sideburns will still be exposed when I wear a hat, so I have to use my hands often to pin my hair. In other words, as long as he has his previous hair, he will maintain this habit. ”

"You mean he cut his hair?" The detachment leader asked.

"Or the killer in the back is shorter hair." Yuan Mu said his conjecture.

"The two doubts you mentioned are very good, and I will find an image expert to deal with them again and see if I can determine the difference. In addition, when it comes to walking stride and frequency, I arrange for someone to do a field experiment. You've been tired for the past two days, so go back to the dormitory and rest for a while, and I'll call you if there's something. The detachment leader patted Yuan Mu on the shoulder and left.

After the detachment leader left, Yuan Mu was stunned for a while, if his guess was correct, the case would become more complicated...... The last robbery and homicide case has not been solved, and this time there is a parody crime...... It's a headache to think about.

However, more difficult questions are yet to come. Since meeting Ji Si'an, Yu Na realizes that she has become the biggest suspect, and she weighs and confesses the matter to the police.

"Another robbery and murder came out, when did the security of the city god be so bad. Who can believe that robbers are everywhere overnight? The young policeman said with some breathlessness.

"It's kind of like making up a story, but you can't rule it all out. The main thing is that our chain of evidence is incomplete. Because it was too dark, witnesses could not identify the suspect. It is still possible that Yu Na's statement exists. ”

"Re-examine the scene to see if there is any evidence of a third person present. The forensic doctor needs to re-autopsy, so he starts with the wound on Pan Fengxia's body to find a breakthrough. ”

After the detachment leader assigned the work task, he took Li Muzi out, and he wanted to verify the source of the sportswear and sneakers.
