Chapter 298 Another Blind Spot in Surveillance

Cen Lian squatted down next to Wu Qiushan, looking at a small section of the wall with cement and bricks that was vaguely exposed after a piece of wall peeled off halfway in the corner.

There was a faint blue fluorescence on it.

Luminol reaction, from the perspective of experimental difficulty alone, is just basic operation for trace examiners, but being able to spray the reagent in the right place is the most difficult part.

Cen Lian knew that Wu Qiushan was suspecting that there might be something in Yu Huafeng's car at the time, or some human fragments.

"Do you think this trace has been processed?" Cen Lian observed the traces of blood on the wall, "Are there any around?"

"It doesn't look like it has been deliberately cleaned," Wu Qiushan pointed to the faint color on the edge of the wall that had not completely peeled off, "It should have been washed away by rainwater naturally. I'm looking for the source of the blood."

Cen Lian resigned himself to taking the reagent bottle and began to search with Wu Qiushan. The splashing of blood must comply with the laws of physics. Judging from the bloodstains on the wall, it seems more like it was accidentally thrown up.

Wu Qiushan stood at the corner of the wall, gestured a light swing, and searched along the corner of the wall, finally landing on an inconspicuous corner on the cement floor.

Soon, dripping blood appeared.

"Look at this track, it seems that there is a body or something that was moved in the process of moving, and a little blood was thrown out because of the small movement." After reading it, Cen Lian touched his chin, chose the opposite direction from Wu Qiushan, and found a parking space closest to the corner of the backyard.

The traces left by the ruts here are relatively dense, and people should park here frequently.

He stood behind the parking space, probably at the position of the trunk, gestured an approximate center line, and then sprayed luminol reagent near the center line.

Soon, a faint blue fluorescence appeared.

Wu Qiushan was also very close to Cen Lian's position at this time. He looked up and gestured roughly, and confirmed, "It was to carry the person out of the trunk. The problem is that Yu Huafeng will stay here for a few hours, and there is nothing to do to pull the body out."

Although no more experiments have been conducted for the time being, Cen Lian and Wu Qiushan can basically confirm that the body being carried is a body.

"It may not be Yu Huafeng who moved it," Cen Lian reminded Wu Qiushan, "Zhao Yitong might have been silenced because of this."

Wu Qiushan frowned. He had thought about it, but it was just a guess and could not be confirmed.

There was no surveillance in the backyard, and even if there was, it must have been destroyed.

"It is difficult to extract DNA from the blood now. Let's wait and see if Yuan Chenxi can find anything," Wu Qiushan tried for a while and then gave up helplessly. "It is hard to say whether Zhao Yitong discovered something by accident or has been waiting here hoping to find something."

Cen Lian was not surprised. Before they came, they basically guessed that there might not be much discovery.

Tang Hua, who had been running around upstairs, suddenly poked his head out of the window of a guest room on the third floor and shouted to Cen Lian and Wu Qiushan, "Brother Cen, Brother Yue, you two come up, there seems to be something wrong here."

The two had just finished their work, so after packing up their things a little, they followed Tang Hua's voice to the third floor.

This is another three-story building next to the lobby. From the first floor to the third floor, all are guest rooms. Tang Hua was just in the northernmost guest room on the third floor. From the window, he could see one-third of the backyard. The parking space where Cen Lian and Wu Qiushan were located was right in the view of the window of this guest room.

"What's going on?" Cen Lian moved quickly and appeared at the window in less than five minutes.

"Look at this position," Tang Hua pointed to the corner of the window, where a little blood could be vaguely seen. "When I just leaned out to see you, I saw something wrong here."

Wu Qiushan's eyes lit up when he approached, "The blood here is relatively complete, and there is a good chance of extracting DNA. You two get out of the way and let me try."

Cen Lian and Tang Hua consciously got out of the way.

"I checked. This guest room was vacant on the day Yu Huafeng checked in," Tang Hua looked at the vacated room, "so the police didn't come to check at the time. I just wanted to see if I could see you from the window of this room. I didn't expect to get something."

Cen Lian was a little confused about whether the blood was from Yu Huafeng or Zhao Yitong.

Theoretically, Yu Huafeng might have found this vacant guest room to observe after his car made a noise, and Zhao Yitong might have specifically monitored the car parked in the backyard in this guest room that was not easy to be discovered.

But he soon tilted the balance in his heart towards Zhao Yitong, because Yu Huafeng stayed in this B&B for too short a time, and he probably didn't know that the window of this room could also see one-third of the backyard.

So the question is, why did he monitor here?

Cen Lian found that this question went around and around and came back to the starting point, that is, what is Zhao Yitong's purpose in opening a B&B here.

"The extraction is done, I'm going back to do DNA now, are you going to go together or do you plan to continue the examination here?" Wu Qiushan turned to look at them after the operation.

"I'll go back with you, there's nothing to find in other places for the time being," Cen Lian now wants to quickly figure out where this Zhao Yitong came from, "Yuan Chenxi should be asking, and I guess there will be results soon."

Wu Qiushan looked at Cen Lian's expression and guessed what he was thinking.

"This bloodstain may have been left here by Zhao Yitong, but it may not be his own. We will know after we go back to test it. He may have found something." Wu Qiushan packed up the survey box and urged Cen Lian and Tang Hua to go downstairs to meet Qu Zihan.

Qu Zihan, who had been busy with the computer in the lobby for half a day, saw them coming out and said, "I didn't get much here, but it can be considered a kind of gain. This computer was moved after the accident, and the case is very messy."

"Case?" Cen Lian didn't expect that the problem was the case.

"The graphics card, hard drive, memory stick, etc. were all taken away. It may be a thief or not, but there are fingerprints on the case. It shouldn't be difficult to find." Qu Zihan pointed to the case cover that she carefully placed aside, "I didn't touch the place with fingerprints."

So Wu Qiushan extracted fingerprints inside and outside the computer host.

"It seems that I underestimated the workload today," Wu Qiushan looked at the fingerprints, "Let's go back quickly and try to match the results as soon as possible."

Tang Hua had already gone out to drive. Seeing that they were still talking, he honked the horn, and the few people packed up and got in the car together.

Half an hour later, the four of them appeared at the Yizhou Municipal Bureau together.

Yuan Chenxi was waiting for them at the door, and the first thing he said when he met them was, "Captain, Zhao Yitong really has a story!"
