Although the sewers had been cleaned, there were still various smells inside because of the enclosed environment.
Fortunately, the poisonous things inside had been cleaned up. Otherwise, even Su Yang would not be able to come down so easily.
As they walked in the sewers, because half a month had passed and there was no more water flowing in, the sewers had gradually dried up.
Su Yang did not walk for long before he saw a small bloodstain in the sewer.
Looking at the bloodstains, Su Yang did not know if he should be surprised or sigh.
This was the place to kill!
The kind old man who had moved the entire country was beheaded in such a dark place.
As they walked forward, footprints began to appear on the ground.
Unfortunately, he could not make any deductions from these footprints because they were of different sizes. They were probably left behind by the workers who cleaned the sewers at that time. As the soil gradually dried up, the footprints looked like a model.
As he continued to walk forward, more and more blood stains appeared.
However, there was nothing on the ground other than blood.
Su Yang shone the flashlight deeper into the cave. He was thinking, even if the murderer had knocked Old Wu out when he was dragged out of the window, how could Old Wu's body still be clean enough in such a dirty environment?
This still didn't make sense, but it was certain that the sewers were the place to kill people.
Su Yang could only continue with his actions until he stopped in front of a pile of ashes.
Looking at the pile of ashes, Su Yang finally smiled. He looked at the time and it was 4:21 in the morning.
It was less than three hours until dawn, and it was Sunday.
School was on holiday, and a large number of people at work were on holiday.
In other words, in another three or four hours, the streets of the entire capital city would have the largest number of people in the morning. After the morning, the afternoon and evening would also be the busiest for the week.
If the murderer was really going to make a big scene as he had guessed, then the time he chose would definitely start at eight o'clock in the morning. However, Su Yang could not be sure which time he would choose.
He silently squatted in front of the pile of ashes and did not move until someone appeared in the sewer again.
Jiang Rou and Chen Jing came over together. Su Yang's team did not have the latter, but Chen Jing did not mind lending a helping hand at this time.
After they arrived, Su Yang pointed at the pile of ashes and said,""The burning was too thorough. I can't be sure what it is, but judging from the appearance of the ashes after burning, it should be something like rubber or oil paper.”
Chen Jing was an experienced person, so she picked up a ball to identify it, but the first to answer was still Jiang Rou."Rubberized gloves, oil-paper cloth, and if I'm not mistaken, there are also foot gloves.”
"Then this is the crime scene. I saw a lot of blood in the sewers just now. This should be the place where the crime tools were destroyed. However, the fact that the tools of the crime had been burned to such an extent meant that the murderer had been here for a long time. Su Yang, you haven't been moving around here, have you? It was highly possible that there would be traces left behind by the murderer in this location.”
Su Yang's lips curled up."I haven't even moved my feet since I found this place. I'm afraid that I'll destroy the traces."”
Chen Jing gave him a thumbs up."To be able to be so cautious, it would be a waste of talent if you don't work as a criminal investigator.”
Su Yang only responded with a smile. He followed Chen Jing and Jiang Rou to open the toolbox and put on gloves and gloves. They began to examine Ember's surroundings.
Not long after, Jiang Rou used a pair of tweezers to pick up a small lump of mud. Then, under the light, she smiled brightly and said,""Look what I found!"
With the help of the light, a strand of hair mixed in the soil was particularly obvious.
Although that strand of hair had been here for a long time, it took a long time for hair to decay. At this moment, one could vaguely see that the hair color was very healthy.
Chen Jing moved closer to the hair and sneered as she looked at it,"Tsk tsk, such healthy hair can't be Old Wu's, right?”
"It's impossible for it to be a person, but it's also possible that it's a worker who cleaned the sewers. Even if it was beside the ashes, it would be fine, so it still needed to be appraised. How about this, Auntie Chen, take the hair away and identify the DNA of this hair as soon as possible. Jiang Rou and I will continue to look for it here. This was the crime scene, so there must be more clues.”
Chen Jing nodded and immediately left with the strand of hair. Jiang Rou and Su Yang continued their search.
However, Jiang Rou seemed to have a purpose for surrounding Ember. On the other hand, Su Yang kept looking around.
Jiang Rou was very puzzled. Finally, she couldn't help but ask,"Leader, what are you looking at?"
"I'm trying to figure out where the murderer cut off Old Wu's head. It should be not far from Ashes. But there shouldn't be any large bloodstains around. Moreover, Old Wu's corpse was so clean that even his clothes were not dirty. It was probably because he was wrapped in this burnt oil paper. However, there was slime in his hands. Could it really be caused by the vegetables?”Su Yang replied.
"It's basically left in every piece of Old Wu's. I think it's really possible.”Jiang Rou smiled bitterly.
"What if one of the fingers is filled with mud from the sewers? He was wrapped up, but how did he stay? Even if he couldn't clean his other fingers, his thumb should be easy to clean, right? Could it be that his finger pierced through the oil paper and left some clues for us?”
As a detective, the most important thing to do was to dare to assume and speculate.
When Jiang Rou heard his words, she was slightly stunned. However, Su Yang had already gotten up and continued to search along the sewers.
Finally, he found the place where the large blood stains were. He was almost lying on the mud to search.
However, perhaps Old Wu had finally shown his spirit, or perhaps his hard work paid off. When Su Yang saw a mural on the ground, a smile that he had never seen before appeared on his face.
"(vertical fold), what symbol is this? Wait, there seemed to be a head above the fold, and there was also a vertical line behind it. This was a mountain!”
After Su Yang understood, he hurriedly said to Jiang Rou,""I'll go out and give Zhang Xing a call. Old Wu knows the murderer. If everything goes smoothly, we can at least lock onto one of the murderers!”
Jiang Rou watched as Su Yang ran out in a flurry. Once he was out, Su Yang picked up his phone and called Zhang Xing."Captain Zhang, immediately conduct a spot check on the people in the nursing home and the students from Grade 12 Class 2 who participated in the Youth Day event on May 4th. Keep an eye on anyone whose name has the word 'Shan' in it!”
