Da Zhao nodded.

"It is confirmed that the deceased is Tan Ran, this is part of the inspection report, and some have not been completed."

Zhou Ning took the report and read it carefully.

The bloodstains found at the scene all belonged to Tan Ran, blood footprints, blood fingerprints, splattered blood droplets, and pools of blood, these results came out, as for the other DNA at the first scene, only Xing Xiaoli's was collected, it seems that the murderer hopes that the police will lead their suspicions to Xing Xiaoli.

However, after looking through it, the test reports of handsaws, kitchen knives and wires did not come out, which made Zhou Ning a little surprised.

"Sister Cui didn't say why she didn't finish the test?"

"Having said that, although there are traces of the deceased's blood on these physical evidence, the ingredients of 84 disinfectant have been found on several things, and they are all in the gaps, Sister Cui said, maybe these things were sprayed with 84 disinfectant before they were used.

She wanted to try it and see if she could extract DNA fragments, after all, although most people know that 84 can destroy DNA after watching criminal investigation dramas, Sister Cui said that what is just oxidative damage of free radicals, although it is not recoverable, it can extract the fragments inside. ”

Zhou Ning nodded.

"If you just spray, there will be residue in the gaps, even if you soak in the disinfectant, if there is grease to block the liquid, you can find residues inside.

Of course, as Sister Cui said, even if it is destroyed, some DNA fragments can be obtained, but this requires a lot of collection and extraction, and the workload is very large, and it also requires a little luck, see if Xu Da is so lucky. ”

"What do you want me to say?"

With the voice, Xu Dayuan pushed the door in, his eyes were a little bloodshot, but his mental state was good, and it seemed that he had made a discovery.

Da Zhao smiled.

"How dare we talk about you behind our backs, Sister Cui said to look at our luck, I want to extract it a few more times to see if we can find something else, after all, these things have been sprayed with disinfectant before use, so it's not to remove the remnants of it."

Xu Da stayed away, after all, these people were so serious, and he was still moved.

"I'll call Section Chief Cui in a while and thank her."

"You're blushing? I don't know the real thing at all. ”

Seeing Xu Dayuan's glaring, Zhou Ning hurriedly said:

"Surveillance delivered?"

Xu Dayuan snorted twice at Da Zhao, and then looked at Zhou Ning.

"I got the video last night, and I sent it to Xiaoqu, the monitoring is very unclear, and a few people from the technical department have been busy with Xiaoqu all night, let's go and see together."

The three of them went upstairs together.

In the laboratory, there was a miasma, Xia Momo was wearing a mask and coughing constantly, Da Zhao hurriedly went in and opened the window, and kicked the two people from the technical department and Xiao Zeng twice.

"Why are your hearts so big, Teacher Xia is here, you can't rest with a few big smoking guns, you want to smoke out, it's like alchemy in this room, don't come to the laboratory in the future."

One output, Zhou Ning and Xu Dayuan didn't stop it, Zhou Ning was really dissatisfied, the first priority of the laboratory was to test the application of the software, and the second was to assist Zhou Ning and them in the investigation of the eucalyptus, none of them were people in the bureau, helping was polite, and they couldn't come over to be the same as the uncle.

Xu Dayuan coughed and looked at Xiao Zeng, who was embarrassed to die and jumped over directly.

"Boss, you're here, the surveillance on September 6th, 7th, and 8th has been repaired here, and we are looking for people frame by frame."

Da Zhao grinned, leaned over, and bumped Xiao Zeng on the shoulder.

"Shaohu gets your head, and you are looking for it frame by frame, Xiaoqu's family has experience, this software can screen personnel on surveillance video, and then analyze all personnel, and finally need to manually compare time and characters."

Xiao Zeng scratched his head, and Xu Dayuan pushed him away.

"On Tan Ran's mobile phone, the last call record was at 12:34 on September 7, which is the package introduction of the mobile company, which we have inquired about, and also found the call recording, and it is determined that it was answered by me.

So the focus of the investigation is on the 7th and 8th, did you find out who went out with a suitcase? Also, what time did she leave on September 6th? ”

At this question, Xiao Zeng was a little stuck, and looked at Xiao Qu like asking for help.

"I just found it, I have taken a screenshot and saved it, Tan Ran left on the afternoon of September 6, and he carried a small suitcase."

As he spoke, Xiaoqu had found a screenshot video and clicked to play it.

Above, the marked time is 15:41, Tan Ran pulled a red suitcase, came out of the unit door, wore a red baseball cap, and talked on the phone as he walked.

Xiaoqu then opened more than a dozen pictures on another display screen, which are all screenshots of surveillance screenshots, and almost everyone in them has a suitcase.

"These are all the people who came out with suitcases from September 7 to September 8."

Several people gathered around the screen, and Xu Dayuan looked at it again, frowning.

"Don't have a gray suitcase of the same style?"

Zhou Ning stared at the screen, the suitcases carried by these people were not small, but if they put a 29-inch suitcase inside, it seemed impossible.

"Is there Xing Xiaoli in this?"

Without Xiaoqu to identify, Xu Dayuan had already pointed to a person and said:

"This is Xing Xiaoli, he walked away with two suitcases."

Zhou Ning took a closer look, although the picture was not clear, but he could still feel Xing Xiaoli's thinness, indeed this height, if he wanted to be a pair skating male athlete, he was a little physically weak, and it was also a little difficult for him to transport the corpse.

"Building 4 of Enbo Community, can you see it from this surveillance?"

"As far as you can see, the easternmost side is the wall, so you can go directly out of the community, and the unit doors are on the north side, so you can't throw the box out of the window, there's a person stuffed inside."

After saying this, Xu Dayuan was also stunned, and then took out his mobile phone and found a satellite picture of the street, the easternmost side of Building 4 is adjacent to a small road, adjacent to a hotel, the hotel is quite high, and a narrow passage is formed here, and both sides of this narrow road can be out.

"It seems that it is a good way to transport it out from the window, and I don't know if there is monitoring behind the hotel."

After speaking, he looked back at Xiao Zeng, and Xiao Zeng nodded quickly.

"I'll go now."

Xu Dayuan thought about it and waved his hand.

"Let's go over, Zhou Xiaozhou, you take people to investigate the first scene for the second time, and we will take people to check the surrounding area, whether there is monitoring to get this location, and check the vehicles entering and exiting the road at both ends, after all, the best way to transport the body is to transfer the vehicle."

Half an hour later.

Zhou Ning and the others have come to Building No. 4 of Enbo Community, just now the car has been around the path outside, and sure enough, the east wall is close to the edge of Building No. 4, and the south side is not a wall, it is an iron fence, and the window is five or six meters away from this fence.

A few people went upstairs, and at the door of 202, a policeman stood here, and when he saw Zhou Ning and them coming up, he quickly nodded his head.

"Forensic Doctor Zhou, you're here!"

Zhou Ning smiled and nodded.

"Yesterday, Wang Ying didn't come back to live, right?"

"The leader said that everyone was asked to live in a temporary room in the gymnasium, and they were not allowed to leave."

This answer is quite satisfactory, after all, throwing the box out of the window can't be done in Xing Xiaoli's room, only from the window of the bathroom on the east side, of course, it can also be 301, 401, 501, except for 101 without the east window, these can be done.

However, if these floors are dropped, it is easier to attract the attention of others.

Thinking that the feet did not stop, several people had already entered 201 directly.

"Da Zhao checked the bathroom, Yang Xuetong went to check the two bedrooms, pay attention to the bloodstains and fingerprints, forget the shoe prints on the ground, mainly to see if there are any traces of the suitcase pulling."

Yang Xuetong carried things to the master bedroom, Da Zhao opened the door of the bathroom, which is exactly the opposite of the 202 pattern, the window is not big, and the width of the fully opened is 65 cm.

Da Zhao approached, and after measuring, he pressed the screen down, and then with a click, the screen rolled up.

As the screen rolled up, a burst of dust flew, Da Zhao poked his head out of the window, and the two dirty wiping marks outside the window were very obvious, and it was black that he couldn't see what it was, Zhou Ning handed him a wet cotton swab, Da Zhao wiped it, and then threw it into the reagent bottle, which instantly turned pink.

"Bloodstains!"

"Well, it's bloodstains, let's take a sample!"

This discovery, for Da Zhao, was like a cardiotonic agent, he excitedly took a sample, and then leaned out, observed left and right, and on the outside of the window, he found a fingerprint, but this fingerprint is not a finger, Da Zhao collected it and held it up to Zhou Ning to see.

"It's difficult to compare, I can't see that there are no traces left by the fingertips."

Sure enough, in the middle of the fingerprints of the two thread gloves, there was a round fingertip mark, apparently in the process of transporting the box out, the thread gloves were broken, and the murderer did not pay attention to leave this mark.

"It can be compared, and if there are no special features, there is a high probability that there are similar lines in this location, and it cannot be used as the main evidence."

Da Zhao sighed, he has always had a good attitude, and Zhou Ning's words couldn't hit him.

"Don't worry about it, it's good if we find clues, this is progress."

Zhou Ning nodded, and Yang Xuetong walked over.

"Team leader, in these two rooms, there is a lot of fingerprint information, I have already collected it, but except for the fluorescent reaction on the handle of the door lock that entered the door, no blood stains were found anywhere else."

Zhou Ning nodded again.

"The murderer can accurately know everyone's work and rest time, enter and exit this unit at will, and even has the keys to 201 and 202, right-handed, has a certain anti-reconnaissance ability, has strength, and is an adult male."

Da Zhao said on the side:

"At that time, when they called Wang Ligang and they understood the situation, he answered the phone and opened the door with his right hand, this is a subconscious action, and it cannot be deliberately changed, according to your image, he is also the object of suspicion?"
