Seeing this, Zhou Ning was stunned.

He guessed that these two people must have a story, but he never expected that there were so many unknown things in it, especially the son of the deceased Zhang Min'an, who was almost fifty years old, asked his father for money like this, how noble is this?

However, since Zhang Minan has the habit of keeping a diary and is still so guilty about Luo Suqin, will he arrange a follow-up for his death?

Thinking of this, Zhou Ning grabbed his mobile phone and dialed Da Zhao's number.

"Hey, you're done with your second survey?"

"Zhou Xiaozhou, you are more ruthless than Xu Da, he urges and urges, keeps chattering in my ear, I'm annoyed enough, you ...... now"

Zhou Ning knew that if he didn't interrupt this goods, he had ten sentences to wait.

"Since I'm at the scene, let's go find things like cameras, tape recorders, tapes, and mobile hard drives, I think Rusuqin has also woken up, so I can ask Xu Da to ask, I think Zhang Minan must have left something like a will."

Da Zhao was stunned, and Xu Dayuan next to him snatched the phone.

"What's wrong Zhou Xiaozhou, did you find something?"

"Diary, I found Zhang Anmin's diary, and I had a diary sandwiched between his translation manuscripts, which recorded Zhang Min'an's son Zhang Guoqing, the amount of time and time each time he came to them to ask for money, as well as the whole process, including threats and intimidation and even harm to the two."

Xu Dayuan took a breath, paused slightly, and said:

"Don't worry, before we came, I had someone go to collect blood for Zhang Guoqing, and DNA analysis was being done over there, and then we compared, as for his father's affairs here, I also told him, he flew to Piano Island in the afternoon, I asked Xiao Zeng to pick up people, and when it came to the direct trial, there was intentional injury, and the trial was not counted.

As for the hospital, I'll go there in person, okay, I'll ask Da Zhao to find the evidence you said, hang up first! ”

Zhou Ning hung up the phone, and the person also breathed a sigh of relief.

Although the countdown to the cause of death is still jumping, everything that can be done now is done, and the rest depends on the comparison results, according to Xu Dayuan, go to collect blood early in the morning and send it for testing, then the analysis of this DNA will come soon.

Just thinking about it, Xiao Sun walked in with a lunch box.

"Forensic Doctor Zhou, I brought you a meal, I don't know what you have to doom."

"Thank you, I'm not jealous."

After eating, Zhou Ning went out directly to the laboratory department.

As soon as I arrived at the door, I saw the door of the laboratory open, and a small chubby woman in a white dress looked up and down at Zhou Ning.

"Hello Sister Cui, I'm Zhou Ning."

"I remember, you have something to do with me?"

Simply asking, but the process of greeting is omitted.

"2.21 The DNA information of the deceased's son will be sent over in a while, and I have to trouble Sister Cui to help compare it with the deceased."

Cui Lili nodded and held up her phone.

"Add me QQ, and I'll send the file later, and the comparison result will be very fast."

"Okay, that's troublesome Sister Cui."

After saying that, Zhou Ning didn't delay, and quickly turned back, Cui Lili looked at Zhou Ning's back with interest in the back, and said to a female laboratory technician behind her:

"This new forensic doctor Zhou is not only handsome, but also has good work ability, and he won't be idle, I said you don't have any ideas?"

The female laboratory technician drank water and kept shaking her head.

"I said section chief, you are just busy with testing, you don't care about the gossip in the technical department at all, this week forensic doctor is not an ordinary person, people are hand-picked in the city, it seems that there is a project, and it is highly valued.

Yesterday, so many people from Qindao University came over, and one of the female teachers was no worse than those stars, and they left with a smile, and at first glance it was a lot of relationship, and I still had self-knowledge. ”

Cui Lili was stunned, as if she remembered something.

"Come to think of it, Director Pang seems to have said before that the red-clothed serial killer was investigated by him, not to mention that he has two brushes, and he is not a master who eats with his face."

......

Two hours later.

Cui Lili took a stack of reports, walked to the 302 office, and as soon as she came in, she saw Zhou Ning standing in front of the whiteboard, with a diagram of the relationship between names drawn on the whiteboard, as well as all the known conditions, this seriousness was eye-catching.

"The results of the DNA comparison of the deceased's son by Forensic Zhou came out, the two are father and son, and the rest of the comparisons are all bloodstains found at the scene, as well as the DNA extracted from the toothbrush and razor, all of which belong to the deceased himself."

Zhou Ning hurriedly took the report and looked through it.

"Thank you, Sister Cui, this report is so timely, thank you for your hard work."

Sister Cui waved her hand, and a rare smile appeared on her face.

"The mouth is really sweet, if you need to test it, just say, this 2.21 eucalyptus is really not easy, it is estimated that the city bureau will put a lot of pressure on Captain Xu, if we need to work overtime, you say in advance, I will make arrangements."

Zhou Ning nodded at Cui Lili, this kindness moved him, after all, there are not many people who are really willing to help in this technical department for two days, most of them are waiting and watching, as for Director Pang, it is also because he has the name of acting director, otherwise he will naturally hide far away.

"After a while, Da Zhao and they will come back from the second survey, and it is estimated that there will be some sampling, this is not in a hurry, just make it tomorrow."

Cui Lili nodded and walked towards the door.

At the moment when the door opened, Da Zhao rushed in with a box and almost hit Sister Cui, although Da Zhao's weight gain rate was fast, his reaction was quite sensitive, and he quickly turned to the side, and the box was also thrown on the ground.

"I'm scared to death, but I can't touch our eldest sister Cui."

Cui Lili glanced at Da Zhao's hand, and the wrist seemed to be twisted.

"Mao Mao is stunned, are your hands okay?"

Da Zhao's signature grinning, raised his wrist and shook it in front of Cui Lili.

"Thank you Sister Cui for your concern, I'm fine, look at the rough skin and thick meat."

Xu Dayuan kicked him in the back.

"Don't get in the way, quickly find out what needs to be inspected, why do you want people to work overtime with you?"

Da Zhao pursed his lips and did not dare to resist.

"Give it to me, I'll just go back and arrange an inspection."

Xu Dayuan was stunned, and quickly stopped talking, Da Zhao was enthusiastic, carrying the box and leaving with Sister Cui, Xu Dayuan walked to Zhou Ning at this time, Zhou Ning looked Xu Dayuan up and down, and saw that he was empty-handed, and his heart was also stunned.

"Didn't find it?"

Xu Dayuan was just about to speak, only then did he find that Da Zhao had gone out.

"Found it, in Da Zhao's place, I haven't seen it yet."

"Recording? Video? ”

As he was talking, Da Zhao ran back, looked at the two of them, and took out a bag from the survey box, which was a box and held it high.

"You can't imagine that I found a box on the shelf, which was sealed with paper, with the words Zhang Min'an written on it, and then a date, and this is the photo I took."

The bag was placed on the table, and Da Zhao opened the camera and found a photograph with a signature in a dashing font and a date dated June 27, 2010 next to it.

"I opened it at the time, and it was a video camera, a brand new camera, and the purchase receipts were all there, as well as the video with the sales staff in the mall, as if to learn how to use this thing."

"The camera and the surface of the box, have fingerprints been extracted?"

Da Zhao nodded.

"Seven or eight fingerprints were found, and Zhang Minan's fingerprints were found on Xu Da's police pass, and they were completely consistent."

Zhou Ning didn't speak, Da Zhao took out the camera, Sun Gaotie had already intimately found the data cable, connected it to the computer, and then found the two videos inside and opened them one by one.

The date on the first video is May 21, 2010 at 14:22.

A saleswoman carefully introduced to Zhang Minan how to use the camera, how to adjust the focus, how to frame the camera, Zhang Guoan asked if I wanted to record myself, how far and how high I needed to go, and the two demonstrated.

The saleswoman asked casually.

"Uncle, did you buy this camera to travel and record your family?"

Zhang Minan shook his head, raised his head and said to the saleswoman with a smile.

"I want to make a will."

The saleswoman was obviously stunned, and then didn't ask anything else, and became familiar with Zhang Minan again, and the video ended immediately.

Without Xu Dayuan's instructions, Da Zhao had already clicked on another video.

The background is an office, the camera shakes slightly, Zhang Minan walked into the picture, sat on a chair, kept kicking the chair to adjust the distance, an old man walked to his side and stood up, and then said a word in the direction of the camera.

"How about this distance, can you fit me into the picture?"
