Chapter 290 A Male DNA
The follow-up autopsy, Zhou Ning quickly ended, compared with Bai Hua's autopsy report, Zhou Ning nodded in approval.

"Forensic doctor Bai did the dissection very carefully, very powerful."

"Don't brag, I'm not as fast as you, or I've handled fewer criminal cases. It takes me a day to complete a death, and there are many shortcomings in the details. Now we have to wait for the test results?"

Zhou Ning nodded.

"The rest of the work is waiting for the test results to come out. By the way, Lao Yang, I forgot to ask you before, have you found the lock on the gate of Wang Hongzhan's house?"

Yang Xuetong patted his head, stepped forward and said:
"I forgot to report. I found two locks and a bunch of keys. I tried it. There were two corresponding keys. Because I couldn't tell which one belonged to the courtyard gate, I gave Xiaobai both locks and keys. Checked together.

A note was pasted on it, let Sister Cui observe it with an electron microscope to see if there is any trace of grease or metal debris left on the key and inside the lock cylinder, as long as the material is different from the two keys , it can be concluded that the key has been allocated, or a key that has been allocated after use. "

Zhou Ning nodded, and had already torn off the disposable surgical gown, hat and mask on his body.

"Let's go, Director Xu is impatient, he urged, maybe some of the test results have been obtained by now, you two have brought all the investigation equipment, I don't know if the safe is opened."

Everyone nodded, the body had been transported away, and they returned to the criminal police team in the front yard together.

As soon as he entered the office, he saw a group of people gathered together. Hearing the sound of the door opening, Xu Dayuan looked up and saw Zhou Ning, and quickly smiled and waved his hands.

"I was just about to call you guys, but you came back unexpectedly. It's really timely. Look at the safe just opened. This thing is an antique, and it's still a bit difficult. We didn't dare to cut it from the back."

The criminal police moved out of the way, Zhou Ning brought Da Zhao and Lao Yang closer, and sure enough the safe was opened, and there was a small door inside, a kid was fiddled with the master key, and with a click, the small door also opened up.

The man raised his head, wiped his sweat with his sleeve, and could feel his nervousness.

Xu Dayuan patted the man on the shoulder and waved towards Zhang Chunbo.

"What are you doing in a daze, give the money quickly, you make people work for nothing, I don't know how many people are you looking for?"

The boy who opened the lock quickly waved his hand, tore off his gloves, and held up the sign on his chest.

"Don't mind the leader, you don't need to pay. We are the lockpicking company designated by 110. We should help you with this."

Zhang Chunbo put his arms around the man's neck and took him away with a smile.

Da Zhao and Yang Xuetong put on their gloves, one illuminated the safe, and the other began to check the inside of the safe. In fact, there is not much space inside, and the upper and lower floors are empty at this time.

Da Zhao squatted down slightly, his eyes were at the same level as the partition in the middle. This angle allowed him to see the traces on the upper part of the partition more clearly, and he held up the camera and clicked.

Xu Dayuan watched anxiously from the side, and he also followed Da Zhao's movements with his waist in, and squatted down.

"You're talking, what did you see?"

Before Da Zhao could speak, Yang Xuetong blocked Xu Dayuan with his hands first.

"Xu Bureau, don't worry, the inside is empty, and now we can only analyze the traces of dust left on it."

Liu Yongxin pursed his lips tightly, trying to hold back his laughter. The people in Zhou Ning's group improved their abilities and temper very quickly. When Xuetong Yang first came, it was a 180-degree change from what it is now.

When Xu Dayuan heard what Yang Xuetong said, he didn't ask any more questions. He took two steps back, sat on the chair, tried to control his emotions, and didn't look in Da Zhao's direction. Such a glance happened to see Zhang Chunbo, who was standing beside Yang Xuetong with a smile Xu Dayuan coughed.

"Zhang Chunbo, are you a trace inspector? Did Wang Hongzhan find someone? When did you arrange to bring him back? Did you send someone to pick him up at the airport?"

A series of life-threatening questions made Zhang Chunbo raise his hands.

"I was wrong, I'm going to confirm now, the person has been found, but the return flight has not been confirmed, after all, the price of the nearby flight is very expensive"

Xu Dayuan made a sharp eye, Zhang Chunbo quickly shut up, and then quickly walked out of the meeting room with his mobile phone in hand.

Zhou Ning raised his forehead. He knew that Xu Dayuan was really in a hurry. After all, the safe was empty, which undoubtedly made the detection more difficult. If the test did not come back, Cui Lili could not urge him to ask Shenzhen City to send Wang Hongzhan back. Sampling and analysis is just asking for help, and he can't say much, so he can only do it in a hurry.

But it's useless to comfort me at the moment, it's better to hurry up and find clues.

Zhou Ning walked to Da Zhao's side, Da Zhao stood up and quickly waved to Xiao Qu.

"Give me the data cable, and the photo will be sent to you. Zoom in for me to take a look. I can't see clearly below."

Xiao Qu moved quickly, the data cable was connected, and the photo was uploaded to the computer. The picture on the display screen was enlarged. Zhou Ning stared at the photo and squinted his eyes.

There are some dust-free traces left on the partition, but these traces are a bit strange, there are six dust-free locations arranged vertically, but there are two horizontally thinner dust on them, how is this caused?
The size and shape of these six vertical traces are likely to be gold bars. Could it be that there are several rows on them horizontally?
At this moment, Xiao Qu has already processed the photos to maximize the contrast. Those traces are already very obvious, similar to the imprints in the shape of fences, and you can clearly feel the shape and approximate quantity of the items placed here.

However, in the gap between the partitions, Da Zhao found a white spot. He turned his head quickly, held a strong flashlight, approached the gap between the partitions, and picked it with tweezers for a long time, and a slender roll of paper was picked out. .

Da Zhao was a little nervous, and did not dare to tear it violently. He wiped the reserved sample outside first, and then used two tweezers to coordinately unfold the paper roll. Receipt-sized paper.

There is a paragraph written on it in small letters with a brush brush. Some parts of the handwriting are blurred, but the content is still very easy to understand.

Due to policy reasons, the spirit of the XX document is now being implemented and the property confiscated during the Wang Zhankui movement is returned. Among them, a total of 978 large yellow croakers (20 standard gold) were cast during the Republic of China. The land is now state-owned and will not be returned. The house has been demolished, which is equivalent to cash compensation. , hereby explain.

Nov. 1981, 12

Seeing the above content, everyone was shocked, Xiao Qu glanced at the picture and said:
"According to the dust distribution in the picture, the area occupied by a large yellow croaker is 13.33*1.66. I compared it, and it is indeed the same size as a gold standard large yellow croaker with a purity of 978 circulating in Shanghai during the Republic of China.

这样的一根978标金大黄鱼，重量在531克，按照去年八月金价380元/克来计算，531*380*20=4035600.00元。”

Da Zhao held up his mobile phone, searched for a while, saw a piece of news about the auction house, raised it towards Xu Dayuan, pointed to the content on it and said:
"You calculated it based on the price of pure gold. Look at this information. On March 2012, 3, at the Pumen Auction, someone auctioned five small yellow croaker gold bars.

The weight of one is 317.5 grams, and the auction proceeds are 75 yuan. This is based on the auction of collectibles. If the average price per gram is equivalent to 472 yuan per gram, according to this calculation, the price of these 20 gold bars is over 500 million yuan. "

Everyone was surprised, Xu Dayuan stared at the paper, took a closer look, and found that the signature was also stamped with the official seal of the Haining County Government at that time, surrounded by the name of the county government, a huge national emblem in the middle, and a cutout mark on the top.

It looks like it was torn from a piece of paper, and it should be in duplicate. After all, there are traces of a square seal on the torn position, but it is impossible to tell what is on it. There is half a fingerprint of red ink pad on the other side, and there There is a half signature, which seems to be part of Wang Zhankui's three characters.

Da Zhao sighed and said with some regret.

"It's a pity that there are no fingerprints left on the partition, and the only scrape mark can be seen from wearing latex gloves. I have sampled and tested it later, but I don't think it is so easy to sell these gold bars .”

Zhou Ning nodded.

"Twenty gold bars, this amount is not usually large, and if it is sold as gold, the purity is 978, the price is uneconomical, and the recovery of gold requires identity registration, and it cannot be sold at one time, unless it is sold privately at a low price."

Xu Dayuan stretched out his index finger and nodded towards Zhou Ning, which obviously reminded Xu Dayuan of this point.

"The deceased was found the next day. The murderer would never have sold so many gold bars in the local area. It would be much easier to leave Qindao or even Ludong area. This can be investigated. I will ask various places later if there are any large gold bars." Gold purchases, and even information to the police.”

Zhou Ning glanced at the time, it was already past three o'clock in the afternoon, at this moment, Zhu Xingxing looked at the laptop and raised his hand.

"Boss, the Laboratory Department has sent a report."

Zhou Ning walked over quickly and looked at the computer. Zhu Xingxing had already clicked download. She was connecting to the printer. Zhou Ning could only look at the test results.

The report contains a lot of content. The blood stains on the gloves they sent for inspection, the blood stains on the partitions and the wooden strips, etc. are all the blood stains of the deceased He Dongmei. A male DNA was found on the inner finger of the glove and the dagger guard. It is in the database. No matches were found.

Xu Dayuan leaned over, unable to squeeze in front of the computer, he could only ask:
"Did Director Zhou find anything in the inspection?"

Zhou Ning nodded and briefly read the comparison results.

"At present, according to the test results, there is only one murderer. Later, the counterparts in Shenzhen City will send Wang Hongzhan's DNA for comparison."

Xu Dayuan looked back and found Zhang Chunbo. Zhang Chunbo shuddered, and quickly dialed a number. After all, it had been four or five hours since Wang Hongzhan was found there. After the blood test, the DNA results were almost ready. After asking, Zhou Ning quickly Holding up the mobile phone, he gave Zhang Chunbo an email address.

After hanging up the phone, Zhang Chunchang let out a sigh of relief.

"The result will be out soon, and it will be sent in 10 minutes."
