Chapter 291 ECG Tattoo

Zhou Ning called Cui Lili and told about the situation here. Everyone in the conference room was checking the time on the mobile phone. Zhang Chunbo kept calling. He hung up the last call and smiled at Xu Dayuan.

"Xu Bureau, Wang Hongzhan, and the others have already boarded the plane. They have coordinated with the airport. The seat has been adjusted there. It will arrive in three hours and 10 minutes. That is, it will arrive at Qindao Airport at 18:42. It will take one and a half hours from the airport. , you can reach us at 20:12."

Just as Xu Dayuan was about to speak, Zhang Chunbo hurriedly held up his mobile phone and said:

"I have asked Wang Yuan and the others to wait at the airport."

Xu Dayuan nodded. Zhu Xingxing had already connected the printer and printed out the report just now. These people were passing it on for viewing. Zhou Ning was staring at the laptop screen. At this moment, the mailbox flickered. He quickly opened the email and started downloading.

After glancing at the result, Zhou Ning was stunned. Seeing Zhou Ning's reaction, Xu Dayuan came over.

"what happened?"

Zhou Ning clicked to print and handed the report to Xu Dayuan.

"The test of the lock and key has not yet produced results. I just compared Wang Hongzhan's DNA with the DNA left by the murderer. They do not belong to the same person. In addition, I asked Sister Cui to compare Wang Hongzhan's DNA with the second deceased Wang Jiahan. Yes, the two are not related by blood."

Big Zhao's eyes were rounded, and his mouth grew big.

"It's not that Wang Hongzhan and He Dongmei have a very good relationship. Why isn't this child Wang Hongzhan's?"

Zhang Chunbo was also stunned, so he hurried over, snatched the report from Xu Dayuan, and read it carefully. Not to mention blood relationship, Wang Hongzhan and Wang Jiahan's DNA had nothing to do with each other.

From the first case analysis meeting to finding Wang Hongzhan to assist in the investigation, during this process, Zhou Ning and Xu Dayuan had no special knowledge of Wang Hongzhan, but Zhang Chunbo was very moved by the relationship between the two from the beginning of his statement. Such a result was unacceptable to him.

"How is this possible?"

Xu Dayuan didn't say anything else, and looked at Xiaoqu.

"Have you finished dealing with the surveillance in Jiaotuan Village?"

Xia Momo handed the computer in front of her to Xiao Qu, Xiao Qu turned on the projector, and a picture appeared on it.

"Leader, take a look. This is the distribution map of surveillance. We got a total of six surveillance videos, but we screened them. The ones closest to Wang Hongzhan's house are No. [-] and No. [-], which are located at the southeast and northwest intersections respectively. .

If someone drives over, they have to go through both ends of this road, but the road is curved, and they cannot see the front of Wang Hongzhan’s house. In addition, if they pass through the alleys on both sides of Wang Hongzhan’s house, they will pass through No. [-] and No. [-] Baisha Riverbank Surveilled roads.

In this way, no matter walking or driving, anyone who can approach Wang Hongzhan's house can appear on the surveillance, so we think it is enough to check these four surveillances. "

As he said that, he clicked on the two monitors, which were marked with numbers 2011 and 8, and the two monitors on the left and right played the surveillance video after 13:20 on the evening of August 00, [-], respectively, and were accelerated to play.

Zhu Xingxing also brought over the computer, on which No. [-] and No. [-] were playing, and all four videos could be seen on the projector. Xu Dayuan quickly ordered everyone to start watching the surveillance video in groups.

After Xiao Qu and Xia Momo's processing, the picture quality is already very clear. The monitors on No. [-] and No. [-] are relatively dark, and there are several street lights in the distance. Xiao Qu used a laser pointer to point to the position between the two street lights.

"Between two streetlights, this location is where Wang Hongzhan's left and right alleys can come out, just stare here."

Time jumped quickly, and several videos were constantly paused. Whenever someone passed by, Xia Momo performed facial recognition. After searching, it was found that these people were residents of Jiaotuan Village.

1:07 Among the four surveillance cameras, a car came out from surveillance No. [-]. Xiao Qu quickly full-screened the video. Under the flash of street lights, he could see that it was a car, but the license plate was removed, and the driver was wearing a baseball cap and Sunglasses, with a cloth covering his face.

Dressing up like this immediately attracted everyone's attention. Xia Momo took a screenshot, and then performed face recognition, but this person was not wearing a mask, but covered his face with something like a vest, not to mention his face, even his ears were not exposed Come.

On the huge projection, the screenshot of the person's upper body was almost in a full-screen state.

I can tell that there is white writing on the orange baseball cap. It seems that there is a WO on it, but the O at the back is a bit small, and the words below are hard to read.

The person's face should be a white T-shirt, with some dark brown spots on it, in the shape of splatters, obviously bloodstains, this discovery made Zhou Ning get closer again.

In the picture, this person is wearing a T-shirt that may be black, the sunglasses are very dark, and the shape of the eyes cannot be seen, but the hand holding the steering wheel can see that there is a black mark on the ring finger of the right hand, which is not a ring. , I don't know if it's a scar or a tattoo.

Zhou Ning set his eyes on the computer screen, seeing Xia Momo's repeated search failures, Zhou Ning stopped her.

"Don't try it. You can't find such a picture. Look at the ring finger of this person's right hand. Is this position suitable for treatment? I don't know if it's a tattoo or a scar."

Xia Momo quickly zoomed in, then nodded.

"I need half an hour, this is not easy to deal with."

Afterwards, Xia Momo went to the corner with the computer in her arms.

"Xiao Qu reversed several monitors and slowed down a bit. I didn't see when this car appeared just now."

Xiao Qu hurriedly operated. Not long after, at 23:20, a car passed by No. [-] surveillance without turning on the lights. Xiao Qu quickly paused and enlarged the screenshot of the picture.

"No wonder I didn't find this car just now. He didn't turn on the headlights, and drove from the southeast to the north side. From this monitoring angle, he could only see the back of the car, and the same license plate was removed."

Zhou Ning waved at Da Zhao, and Da Zhao leaned over. He knew what Zhou Ning meant, and watched it on the screen for a while, then asked Xiao Qu to slow down the video, then raised his head and said:

"This car is a 2006 Geely King Kong 1.6L manual model. The listed price is more than 6. It should be rear-ended, you can check the same model car that has passed through the insurance."

Da Zhao's words aroused hope in Xu Dayuan, and he quickly waved his hands at Tao Zhenshan and the others. Everyone started to move, calling and going out.

Xu Dayuan pondered for a moment, then walked to the side of Zhou Ning and Xiao Qu.

"Jiao Dazhuang's daughter-in-law said that one day in early August, Jiao Dazhuang went to the deceased's house to help with work. After eight o'clock, he saw a car going to their house. Can you find this car?"

"Don't know the exact date?"

Xu Dayuan dialed a number, and the other party rang seven or eight times before connecting.

"Is Jiao Dazhuang?"

"It's me, who are you?"

"I'm from the Criminal Police Detachment of Qindao City. I'm investigating the murder of He Dongmei. My wife Zhu Xiaohui responded that when you were working for He Dongmei's house, you saw a man driving to He Dongmei's house. Do you remember the exact date?" ?”

Jiao Dazhuang on the other side of the phone was stunned, and then cursed.

"I was talking nonsense, I didn't see anyone."

Xu Dayuan knew that this Jiao Dazhuang definitely didn't want to get burned. After all, if he was from a village, if he saw a man go to Wang Hongzhan's house at night, he would look like a gossip.

"Don't think too much. We just want to investigate He Dongmei's death. I can't tell you the specific details, but I hope you can tell the truth. This will help us a lot in solving the case."

Jiao Dazhuang was silent for a long time before he said:

"Let me take a look at the payment record. I recharged the phone the day before. I'll get back to you later."

After hearing the content, Xiaoqu began to search for Jiao Dazhuang's mobile phone payment information, and quickly found that on August 2011, 8, Jiao Dazhuang recharged his mobile phone with 6 yuan.

At this moment, Jiao Dazhuang's call came back.

"Officer, I just checked. I recharged the money on August 2011, 8. The next day was Sunday. The parents of our children who all studied with Mr. He went to Wang's house together, and helped her put down the tiles before. Afterwards, the rubbish is cleaned out."

"Very good, can I recall, what time did you leave the Wang family? Also, what characteristics did you see about the car and the driver, such as the color of the car? Is the driver male or female? Tall, short, fat, thin?"

"I can't remember the exact time. I only know that it was after eight o'clock when I got home. The car was not white, but very light in color. The driver was not tall and looked very strong. He was about the same as me. It's less than 175, but it looks like [-] to [-] catties. I really didn't look carefully at what it looked like.

But when the man got out of the car, he was carrying a supermarket bag in his hand. I glanced at it and saw that there was milk powder and some snacks. After this point, it was probably food for the children, and it was the first time I saw it. Someone went to see Mr. He. "

Xu Dayuan thanked him and hung up the phone.

Although Jiao Dazhuang didn't say much, he could feel a kind of protection for Teacher He.

At this time, Xiao Qu has already called up the surveillance on the night of August 2011, 8. It is still from four surveillance angles. When searching together, everyone raised their heads and looked at the fast-forward video.

At 8:07, in video No. 93104, a gray car appeared in the field of vision, played at reduced speed several times, and Xiaoqu finally intercepted the license plate number Lu B[-].

Without Xu Dayuan's instructions, Da Zhao had already taken out his police phone and searched, and the information of the vehicle and its owner was quickly displayed.

“鲁B93104，2006款1.6L银灰色吉利金刚，车主叫王红文，1980年3月3日出生。”

Zhou Ning glanced at it. Da Zhao had searched for Wang Hongwen's detailed information at this time. His work unit was the No. [-] Primary School in Hai'an City, and he was a colleague of He Dongmei. kinship?

At this moment, Xia Momo said loudly:

"The picture has been restored. This pattern is a tattoo of an electrocardiogram. Take a look at the picture."
