Chapter 164 Where did the blood sample go?
Da Zhao raised his camera and kept clicking to take pictures. No need to explain at this time, everyone guessed that it was a cake.

"It didn't even digest?"

Zhou Ning shook his head, and looked at Zhu Xingxing who raised the question.

"Cream cakes are usually fully digested in 4-6 hours. There was a black substance in the esophagus just now. I think it is the process of gastric contraction, and part of the stomach contents were squeezed out. The cake that the deceased ate that night should be far more than this amount. "

Liu Yongxin was on the side, nodding constantly.

"Let's take a sample. Stomach contents, esophagus residues, and blood in the heart. In this digestive state, the deceased died about an hour after eating."

Zhou Ning nodded, his face serious.

"It seems that Dong Chengwen is lying. He went out at eleven o'clock, not to buy wontons. The cakes they ate around ten o'clock can't be hungry an hour later."

This judgment is naturally recognized by everyone. After eating an eight-inch cake at ten o'clock, you will be hungry at eleven o'clock?

This excuse is really clumsy, but why did Dong Chengwen say that?

What is he trying to hide?
Liu Yongxin waved his hand. Sun Gaotie had already taken all kinds of samples and sent them directly for inspection.

On Zhou Ning's side, the dissection of Dong Xiaomi had been completed. He stepped aside and raised his chin at Zhu Xingxing.

"Come and try to suture. The deceased in the fire case cannot simply suture with a single thread. They need to find soft tissue and suture with a single needle."

Zhu Xingxing nodded vigorously. This trust made Zhu Xingxing a little excited. He rubbed his gloves, started to find the needle holder and sewing needles, and sewed up the corpse one by one.

Da Zhao turned off the video equipment, and then he breathed a sigh of relief.

"I can't see such a young dead person. I will find someone to send the body back, and then send Fang Hua's body."

After saying that, he turned around to make arrangements, and after a while Fang Hua's body was brought by cart, and Dong Xiaomi's body was also taken away. Judging from the appearance alone, Fang Hua's burn marks were more serious.

Zhou Ning changed his gloves and called He Shancun.

"I said what's wrong with you?"

"I know you're busy, so I'll ask you something. After Fang Hua was admitted to the hospital for rescue and blood samples, whether they were kept or handed over? I remember that you would keep some of the blood samples when you encountered such a case."

"Let me ask in a moment."

He Shancun asked the head nurse, and then said to Zhou Ning:
"When the blood was collected, people from the Jingkou branch asked for a blood sample. As for where it was sent, we don't know. What do you want to know?"

"A cake box was found at the deceased's home. After analyzing the remaining substances, it was found that there was an ingredient of diazepam injection on it. So I would like to ask whether the deceased took blood samples at that time. After all, if the person was not asleep, he would not be unable to Dodge, but honestly be burned on the bed."

He Shancun was stunned, this analysis made him a little stuck, and then there was the sound of metal clips rummaging through the phone.

"Wait a minute. Dr. Chen admitted Fang Hua that night. I remember he wrote about this in his medical record. I'll check the medical record and give you a message later."

He Shancun hung up the phone. It seemed that Dr. Chen had discovered something, but he didn't know if there were any records in it.

Zhou Ning glanced at the corpse on the dissection table. The cause of Fang Hua's death was issued by the hospital. Extensive skin burns caused failure of various organs.

Zhou Ning took a deep breath and began to dissect Fang Hua's corpse. This time, the speed was very fast. The dead man's dura mater shrank, there was a thermal hematoma between the inner plate of the skull and the dura mater, respiratory mucous membrane edema, partial airway obstruction, and twelve in the stomach. Soot is visible in the intestine.

The deceased's fingernails, hair, vaginal contents, and slices of various organs were all sent for examination.

After Zhou Ning finished his concluding speech, Zhu Xingxing also finished stitching. His hands and feet are quite dexterous, and he can attack the deceased in the fire case, which is very awesome.

Da Zhao has turned off the video equipment, and Zhou Ning gave Zhu Xingxing a thumbs up.

"The performance is very good. When the autopsy is performed in the future, you can do it with me."

Zhu Xingxing was extremely excited, and tried hard to control the expression on his face. The little tiger teeth showed for a while, and then hid them for a while, and Da Zhao coughed twice.

"I said, it's already noon, shall we go to the cafeteria? Or call back?"

Sun Gaotie retched, and looked at Da Zhao resentfully.

"Brother Li, you are too much. I just recovered a little bit. Can you stop thinking about what to eat in the dissection room?"

Da Zhao waved his hand.

"Stop protesting and just go through it a few times. Since everyone agrees, I'll send you and Zhu Xingxing to cook meals for the cafeteria. The autopsy report should come out as soon as possible. I'll go to the laboratory.

Captain Xu is impatient. If he knows the autopsy is over, he will jump over immediately, opening his mouth to ask for the results of the autopsy, and the results of the autopsy. Why are you winking at me to avoid labor? "

Sun Gaotie stared at Da Zhao and kept winking at him.

But Da Zhao was immersed in his emotions and didn't pay attention to Sun Gaotie's movements. After he finished speaking, he found that Zhou Ning and the others subconsciously took a step back.

"Why? Looking at me with this expression, what's on me?"

A snap sound interrupted Da Zhao's voice.

"Hey, who is looking for Team S Xu Hehe, you came in time!"

Xu Dayuan gave Da Zhao a blank look, and looked at the dissecting table that had been cleaned.

"Your boy is in need of a beating, no big or small, you wait for me to report you, Zhou Xiaozhou, your autopsy is over? Have the test results come out?"

In a word, Sun Gaotie and Zhu Xingxing both bowed their heads and laughed, not to mention that Da Zhao learned really well just now.

Liu Yongxin gave Xu Dayuan a blank look. Since he was not in Qidong, Liu Yongxin had enough confidence. Before Xu Dayuan urged himself, he didn't think it was a big deal. He didn't want to urge his apprentice like this, but he quit.

Lifting his chin, he asked Xu Dayuan:
"Don't come in and ask for something, I know you're in a hurry, but if you want the horse to run, you have to let the horse graze, right? First go upstairs, Xiao Sun and Xiao Zhu go to the cafeteria to fetch food, we all eat in the laboratory, Just to talk about the autopsy, Da Zhao will go to the laboratory to urge the results."

Xu Dayuan rubbed his nose and showed a smiling face.

"to make!"

Talking about several people going upstairs, Zhou Ning quickly sorted out the autopsy reports, and then came to the laboratory. Da Zhao chased after him, and actually got a few reports in his hand.

"So fast?"

Big Zhao grinned.

"Sister Cui personally conducted the poison test. Besides, we have a direction, so naturally it will be done faster, isn't it?"

Holding the report, Zhou Ning quickly entered the laboratory, and turned to the last page. Zhou Ning's movements froze slightly. Seeing this, Xu Dayuan hurried over.

"Tell me quickly, what's the situation? Don't make me rush, okay?"

Zhou Ning raised his head slightly, handed the report to Liu Yongxin, and then said:

"Fang Hua found cake residues in the crevices of her fingernails, and also found diazepam in it, but the content was extremely small. Her stomach was empty. After all, it was kept in liquid after many days of rescue. This cannot be detected. .

As for the cake in Dong Xiaomi's stomach, diazepam was detected, and the content of diazepam in the heart blood was extremely high, 70 μg/ml.

Even for an adult, this amount will cause poisoning and drowsiness, coma in mild cases, and cardiac arrest in severe cases. Therefore, even if Dong Xiaomi did not die of suffocation due to fire, he would have died of drug poisoning. "

Xu Dayuan frowned, before he could say anything, Zhou Ning's cell phone rang, He Shancun called, and Zhou Ning quickly connected.

"I found Fang Hua's medical records, which recorded her rescue process. When she was delivered, she had bradycardia, lying, tremors, and vomiting. At that time, the rescue was based on the symptoms. Although the lying and tremors were relieved quickly, the heartbeat The slowness was corrected after 24 hours.

If, according to what you said, Fang Hua had taken a large dose of diazepam before being burned, then this symptom would be correct. Thanks to the fact that he vomited in the ambulance at that time, the remaining amount of vomiting in the stomach was almost the same, otherwise it might be possible. Unable to make it to the hospital.

In addition, I have found the signatory for the blood sample you mentioned. This person is Zhang Pengfei, a forensic doctor in the forensic office of the Jingkou Sub-bureau. You don't need a phone number, do you? "

Zhou Ning glanced at Xu Dayuan, seeing Xu Dayuan shaking his head and taking out his cell phone, he said:

"No, thank you!"

After he finished speaking and hung up the phone, Xu Dayuan had already dialed his cell phone, but no one answered after it rang for a minute, this person also stepped up and dialed the number again, this time he got connected right away.

"Captain Xu, we just asked the central hospital. When the deceased Fang Hua was being rescued, Zhang Pengfei, the forensic doctor of your branch, went over to ask for a blood sample of the deceased. I asked the laboratory department of the city bureau. There is no record of your submission. I want to know Where did the blood sample go?"
