The person who called the lock-picking company opened the door and walked into Hu Yujie's residence, and the orderly arrangement in the dusty room made everyone's eyes shine, and even gave birth to a breathtaking emotion from the bottom of their hearts.

If Jia Wei is here, he will definitely sigh again. ”

Hearing Xiao Hua's words, Rong Liang continued: "I can guess what he will say?"

"How?"

"If any big man can marry such a daughter-in-law, hey, isn't his life the same as the emperor?"

Rong Liang even learned Jia Wei's tone vividly, which immediately amused everyone.

Since he didn't see blood stains in the room, he had been thinking about how to break through Lin Jia, who had a heroic psychological defense, and then remembered that Ling Zhan was the police who said that the security office of the University of Science and Technology had reported to him, so he asked: "Team Ling, did Hu Yujie commit suicide by cutting her wrists in the school library?"

"Yes. Since the school library is busier on weekends, the four administrators are divided into two groups and take turns on duty. ”

"Why didn't the other administrator discover Hu Yujie's anomaly in time?"

"I heard from the school security department that the other administrator went out to buy food. And the two said that they would go back to Hu Yujie when she came back. After not wanting to rush back to the library, he found that Hu Yujie had already ....... Speaking of this, Ling Zhan suddenly stopped.

"Did Team Ling also think of something?"

"Yes. Wait a minute. ”

As he spoke, Ling Zhan took out his mobile phone and immediately dialed the criminal police team members who were guarding Hu Yujie in a coma in the hospital.

"Ling Ju, is there something wrong?"

"Have you paid attention to which part of Hu Yujie's hand she hurt? In addition, ask the doctor, is the blood vessel cut by Hu Yujie an arterial vessel or a venous vessel?"

"It is a venous vessel on the right wrist, 10 centimeters from the margin of the lower palm, medially. ”

"Are you sure?"

"Yes. Just now, I heard the attending doctor muttering that the location of Hu Yujie's wound was very strange. So I asked in passing. ”

"Also, how many milliliters of blood was transfused into Hu Yujie today?"

"The record on the bedside medical record card is 1800 ml. ”

Hanging up the phone, Ling Zhan immediately called the security office of the University of Science and Technology again.

"Do you know whether Hu Yujie usually uses her left hand or right hand to hold things?"

"Left hand. Hu Yujie is a member of the school's badminton team and also has the title of golden left-hander. ”

"Thanks, can you tell us the phone number of the other administrator?"

"Yes, I'll send it to you right away. ”

Soon, after the number was sent, Ling Zhan dialed the administrator who was on duty at the same time as Hu Yujie.

"Hello, I'm Ling Zhan from the Serious Crime Team of the Municipal Bureau, and I have a question I want to ask you about. ”

"Speak, please. ”

"Did you tell Hu Yujie how long it would take when you went out to buy food?"

"Nope. The other party paused and explained, "Needless to say. Because everyone is used to buying food at the fast food restaurant diagonally opposite the school entrance, the round trip is usually between 20 and 25 minutes. ”

"And how long did it take you this time?"

"Although I didn't pay attention to my watch at the time, there was no delay in between, it should have been a little over 20 minutes. ”

"Got it, thank you. ”

Putting down the phone, Ling Zhan said to Lin Jia: "Since the normal pressure difference of a person is generally 40 mm Hg, theoretically speaking, the time to die from cutting a wrist vein is about 1.5 times that of cutting an artery." When the blood loss reaches 1/4 of the total blood volume of the human body, if it cannot be rescued in time, it will be life-threatening. When the blood loss reaches half of the total blood volume, it is almost impossible to rescue if it is detected a little later.

According to the weight of Hu Yujie shown in the database, her weight is 51 kg, and the total blood volume should be 7~8%, that is, between 3750 ml and 4000 ml.

Under normal circumstances, the maximum time to cut an artery in the wrist is about 15 minutes. According to this calculation, it takes about 22 minutes to cut the vein.

As far as Hu Yujie is concerned, according to the amount of blood transfused, her blood loss should not exceed 1,700 milliliters, and it will not take more than 20 minutes. In other words, Hu Yujie's real intention in cutting her wrists may not be to commit suicide. ”

"Team Ling's analysis is good. Hu Yujie chose to commit suicide by cutting her wrists in just 25 minutes when her colleague went out to buy food, and she cut the wrist vein, according to the calculation of her blood loss, and it was not the first time after her colleague left, her intention is indeed questionable. ”

After such an analysis, Lin Jia naturally admired Ling Zhan's breadth of knowledge. Similarly, Ling Zhan also admired Lin Jia's extremely keen professionalism.

At this time, Xiao Hua walked over with a men's pajama in his left hand and a men's shirt in his right hand and said to the two, "Forest Bureau, Team Ling, look." This was found in the closet in Hu Yujie's bedroom. Both the pajamas and shirts have obvious signs of being washed not long ago, and you can even smell detergent on them. ”

As he spoke, he handed Lin Jia the pajamas in his left hand and the shirt in his right hand to Ling Zhan. Because the two didn't understand what Xiao Hua wanted to say for a while, they didn't speak.

"It's just that this men's pajamas look like they've never been worn. Xiao Hua pointed to the collar of the pajamas in Lin Jia's hand and continued: "Lin Bureau take a closer look, if it is worn clothes, no matter what kind of detergent is used and what method is used, it is impossible to wash such traces, especially the collar part. ”

Indeed, after Lin Jia took it in his hand and observed it repeatedly for a while, he said with great certainty: "You are right, although this pajama has been washed, it is almost certain that it has never been worn." ”

Immediately, Xiao Hua said to Ling Zhan: "According to the size of the shirt, it is the height of the hero. It's just that this shirt seems to have not been worn in a long time. ”

Ling Zhan looked at the shirt in his hand for a while, and asked Xiao Hua with some confusion, "How did you see it?"

Xiao Hua smiled slightly: "If you want to keep the shirt you wear often without any wrinkles like this one, you must be ironed often." The forest bureau knows that clothes that are often ironed are easy to distinguish. In particular, the collar and cuffs should be relatively smooth. ”

Ling Zhan glanced at Xiao Hua when he heard this, and said with some guilt in his eyes: "Take it back and hand it over to the technical department to see if you can detect anything from it." ”

"Also, Team Ling, there is a pair of men's slippers in the shoe cabinet on the porch, which looks like they have just been worn. ”

"That's not right. ”

"How?"

According to Yue Xiangqi of the criminal police team, they blocked the entrance of the community and were in a hurry to leave. Since Hu Yujie was on duty in the school library and did not accompany him back, it means that there must be a medicine spoon on Yinghao. ”

Lin Jia shook his head and said, "Before interrogating Youyinghao, I looked through the items that Captain Yue and they searched for from him, and I didn't see any keys. ”
