I'm not a super cop

Chapter 399 Gradually Prominent
A burst of hurried footsteps came to his ears, Zhang Lei came down the stairs with a DSLR in his hand, saw Xiao Ran staring at the washstand in a daze, and couldn't help asking: "What are you looking at?"

"Is it taken here?" Xiao Ran pointed to the toiletries on the storage board.

"I don't know, I've been upstairs all the time." Zhang Lei was taken aback when he heard the words, walked over and raised his camera to 'click' to take a few photos, and asked doubtfully, "Is there any problem?"

"It should be a cup missing." Xiao Ran frowned and said.

"How do you know that it was a cup that was put here before? ——Maybe it was hairspray or something. I just threw it away after I ran out of it recently."

Zhang Lei looked at the circle of water stains and didn't think much about it. After all, everyone's current general view on this case is still seeking revenge or sex for money because of conflicts. It is a bit outrageous to say that the murderer has always lived in Dong Haonan's house.

After all, if the murderer has been living in Dong Haonan's house, coming and going in and out on weekdays, the people around him should have some impressions even if they have a bad relationship with Dong Haonan's house.

Xiao Ran nodded, and didn't jump to judgment. He said that he didn't finish watching the scene, and he rushed to draw a conclusion through a storage board, which was a bit arbitrary.

"What's going on upstairs?" Xiao Ran asked casually.

Zhang Lei organized his language and said: "The third floor is only half a floor. There is a small machine for processing, and a few old tables and chairs. It is messy. There are two bedrooms on the second floor, one is a guest bedroom, and no one lives there. The other room has a computer and some packages that have not been delivered in time after packaging. It should be a workshop for online order acceptance. There are not many things in the living room. There is an old sofa and some handicraft products piled up. "

"I'll go up and have a look." Xiao Ran pointed upstairs.

"Okay, then I'm going out." Zhang Lei nodded slightly, and quickly walked out of the stairwell with the camera in his hand.

Xiao Ran went up to the third floor first.

It is said to be the third floor, but in fact it should be the second and a half floors. There is a small processing machine here, with hacksaws, hammers, chisels and other tools beside it, which are scattered in the thick processing debris.

It is not difficult to see that Dong Haonan and his wife are not only disgusting outside, but also very dirty at home. Even though there is such a thick pile of sawdust on the ground, they are unwilling to spend some time cleaning it.

Xiao Ran kicked the sawdust on the ground, exposing the concrete floor below, and found nothing new.

After walking around the third floor twice, Xiao Ran went down to the second floor. In the room facing the stairs, the team leader Shao Yong and He Xiaoli were looking at something on the computer screen in the room.

Xiao Ran walked over and stood at the door to watch. It turned out that he was looking at the usage traces on the computer.

Guo Ran and the others next to them were scanning the packages that hadn't been sent out one by one with an ultraviolet lamp. Once they found palm prints or fingerprints on the packages, they put them in the evidence bag and prepared to take them back to the technology center for extraction.

"The usage records are all in the browser and the PC version of Weichat, but there is a VPN file installed on the computer, and there were traces of using it over the wall yesterday. As for whether the account logged in on Weichat is the murderer's, this needs to be confirmed. Take the computer back and hand it over to a network investigator." The technician sitting in front of the computer said to Shao Yong and He Xiaoli.

Upon hearing this, Xiao Ran immediately asked, "Has the murderer used this computer?"

He Xiaoli said uncertainly: "There are obvious cleaning marks on the desktop and keyboard. I don't know if Dong Haonan's family wiped it, or the murderer used the computer before and after committing the crime, and then cleaned it up."

Xiao Ran leaned over to take a closer look at the mechanical keyboard, and it was indeed cleaned, but the few keys with illegible writing on it showed that this keyboard had been used for a long time.

But from all the signs upstairs and downstairs, it can be seen that Dong Haonan's family is very ruined. They don't clean up the housework, but they clean this keyboard. Is it possible?

Moreover, the writing on several keys on this keyboard has been worn away. After using it for so long, given the laziness of Dong Haonan's family, this keyboard should be very messy.

But now the keyboard has been rinsed very clean, and the dust and debris in the gaps under the keys have also been cleaned up. This is obviously not done by Dong Haonan and his wife, it is most likely done by the murderer.

If the murderer used the computer while committing the crime, even if he is afraid of leaving fingerprints on the keyboard, just wipe the surface of the keyboard.

In such a stressful time, is it necessary to spend a lot of effort to clean a keyboard?

——Unless, like the missing cup downstairs, the murderer had used this computer for a long time, leaving too many traces of his life around this keyboard.

Xiao Ran thought of the mechanical keyboard in his residence.

Sometimes when I eat in front of the keyboard, all kinds of soup will splash into the keys, and the hair that usually falls out can’t come out even if I drill into the keyboard. It must be cleaned from time to time to keep it clean.

So in this keyboard, are there traces of life such as the murderer's hair before? ——If so, did the murderer stay at Dong Haonan's house temporarily, or did the husband and wife hire helpers?

Xiao Ran looked again at the pile of packages that were put into the evidence belt. If the murderer had worked in Dong Haonan's house, there might be fingerprints of the murderer on the package.

"What are you thinking, so devoted? What do the people outside say?" Shao Yong pushed Xiao Ran's shoulder.

"Oh, I'm looking to see if there is anything left in the keyboard."

Xiao Ran snapped back to his senses, and quickly said: "The people outside...the people outside have a very bad opinion of Dong Haonan's family. The couple themselves are a bit rascals, and they dote on their children very much. They often break out conflicts with others because of children's problems. "

After briefly talking about the evaluation of Dong Haonan's family by the people outside, He Xiaoli folded her arms and shook her head, saying: "This family is too bad at ordinary times."

"The high probability is that it is because of the child, or the conflicts between the couple in their daily lives. The small probability is that the murderer committed suicide because of sex and money. After being beaten, he killed with passion."

Shao Yong said, and then looked at the keyboard that was put away by the technicians along with the mainframe, "It may also be a hired killer. After the murder, he used the computer to climb over the wall to complete the transaction."

"Killer?" He Xiaoli sneered and said, "Old Shao, have you watched too many police and gangster movies recently? What kind of killer is so brain-twitching? He has a life to make money but not a life to spend!"

"Hey, what kind of gangster movie am I watching? We work every day, and if we record it, it's a gangster movie, and it must be more exciting than TV dramas!"

Shao Yong grinned, and then said seriously: "But it's not impossible. Dong Haonan's family has offended so many people. If someone wants to hire someone to kill them, it just so happens that someone doesn't want to live. If he takes the job, he can still help his family." People leave a lot of money. We have encountered it before."

"Too."

He Xiaoli nodded, and then complained helplessly: "But you said, can't Dong Haonan's family live a good life? If we have to do this and offend so many people, we can list a few pages of major suspects now!"

"This matter...Xiao Ran, there is a saying on the Internet that you can't die if you don't do it, right?" Shao Yong asked.

Xiao Ran pursed his lips and smiled, "Yes, testing on the verge of death..."
