God-level Crime-solving Group

Su Yang was about to hang up after explaining, but Jiang Rou hurriedly said at this moment: "Wait for the team leader, there is an important clue, Team Wu's body was detected by Teacher Chen. He and Mr. Li Changkuan are busy examining Mr. Wu's body. I detected some weird things in his fingernails. It's so subtle that it's almost negligible."

"what?"

"There is dirt in the nails, but those dirts contain sulfides. Mr. Wu's nails are not very clean, and they are very long. It should be caused by no one trimming them for a long time. The previous task force also carried out investigations on the dirt in the nails. After testing, Mr. Li Changkuan's autopsy report also mentioned sulfide. I asked Mr. Li why he didn't verify the source of the sulfide. Mr. Li said that the sulfide was caused by Mr. Wu's use of sewage sludge to manage the vegetable garden. ."

"There is a wellhead for a sewer in the backyard of the nursing home. Six months ago, a factory secretly discharged sulfide. After it was reported that the sewer was stopped because of the protests of the elderly, the sewer was abandoned and no longer used. Later, the elderly asked the hospital for many times. Under the request, the nursing home finally invited some people to clean up the sewers half a month ago. At that time, Mr. Wu said that the silt in the sewers was fertile and asked for some to fertilize the small vegetable garden he and several other elderly people opened. ."

The sludge in the sewer is not really a fertilizer, especially for vegetables and the like.But the old people don't know that much. Old Wu may not know enough about science, so he uses silt as fertilizer, and he treats it every day, resulting in the existence of silt with residual sulfide in the nails!

There's nothing wrong with Li Changkuan's explanation. Even if Su Yang didn't figure out how the murderer killed, he probably wouldn't regard the silt that had a reason to exist as an object of suspicion!

But at this moment, the meaning of this clue is completely different!

Jiang Rou even explained his thoughts directly: "Team leader, before you left the city bureau, you told me that you couldn't let go of any details, and you also told me the murderer's possible killing methods. Do you think the murderer would Did you transfer Elder Wu to the sewer to kill him, and then bring back the headless body?"

"There's no need to doubt, there is no second possibility except this. There is no surveillance in the backyard of the nursing home. There is no surveillance on the road from Mr. Wu's room to that part of the road. The murderer is the place where he went!" Su Yang moved towards the sewer. Walking away from the well, he said with great certainty.

Jiang Rou's face showed a look of anticipation: "Is it possible that the other end is still in the sewer? Maybe the murderer is playing a mind game with us?"

"That's impossible. If the murderer is only playing mind games, there is absolutely no need to kill Wu Qi. There are two types of murders, one has a reason to kill, and the other is just an excuse for impromptu murder! The case is now getting closer and closer to the second It's possible, Jiang Rou saves the sulfide, and if it's in the sewers in the killing place, then their traces will be revealed soon!"

"Okay, I'm at the wellhead of the sewer now! You'd better bring your tools to the nursing home. The murderer can keep Mr. Wu's room without traces, but he certainly can't go in the complicated sewer. No trace!"

Su Yang held the phone and stared at the manhole cover of the sewer!

Chapter 39 Vertical Fold!

Although the sewers have been cleaned, because of the closed environment, there are still all kinds of flavors left in it.

Fortunately, the poisonous things in it have been cleaned up, otherwise even Su Yang wouldn't be able to come down casually at this moment.

Walking in the sewer, because half a month has passed, and there is no more water inflow, the sewer has begun to dry up gradually.

Su Yang didn't walk for long when he saw a small piece of blood in the sewer.

Looking at the bloodstain, Su Yang didn't know whether to be surprised or to sigh.

Murder is here!

That kind old man who moved the whole country was beheaded in such a dark place.

Going a little further, footprints have begun to appear on the ground.

It is a pity that these footprints cannot be calculated, because they are different in size, it is estimated that they were left by the workers who cleaned the sewers at that time.As the soil dries, the footprints look exactly like the model made.

Going forward, more and more bloodstains appeared, one piece here, one piece there.

It's just that on the ground, apart from blood, nothing else was found.

Su Yang put the flashlight deeper, he was thinking that even if the murderer stunned Mr. Wu when he dragged Mr. Wu out of the window, why did Mr. Wu's corpse still keep enough in such a dirty environment. clean?

This is still unreasonable, but it is certain that the sewers must be the place to kill people.

Su Yang could only continue what he was doing until he stopped in front of a pile of ashes.

Looking at the pile of ashes, a smile finally appeared on Su Yang's face, looking at the time at [-]:[-] in the morning.

It was no more than three hours before dawn, but it just so happened that it was Sunday again.

Those who go to school are on vacation on this day, and a large number of people who go to work are also on vacation.

That is to say, in another three or four hours, the streets of the entire Beijing will have the most crowded mornings in a week.After the morning is over, the afternoon and evening will also be the most crowded during the week.

If the murderer really wants to make a big move as he guessed, then the time he chooses will definitely start at [-]:[-] in the morning.However, Su Yang could not be sure which time period he would choose.

Silently squatted in front of the pile of ashes, motionless, until another person appeared in the sewer.

Jiang Rou and Chen Jing came over together. Su Yang's team did not have the latter, but Chen Jing didn't mind giving a helping hand at this time.

After they arrived, Su Yang pointed to the pile of ashes and said, "It burned so thoroughly that I can't be sure what it is, but I can tell by looking at the burning ashes, it should be something like rubber or oiled paper."

Chen Jing is an old Jianghu, so she pinched a ball to identify it, but Jiang Rou was the first to answer: "Rubber gloves, oiled paper cloth, and foot covers as well."

"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. But the crime tools burned to this extent, which means that the murderer stayed here for a long time. For a while. Su Yang, you shouldn't move around here, right? It's very likely that there will be clues left by the murderer in this area."

The corner of Su Yang's mouth curved: "I haven't even moved my feet since I discovered this place. I'm afraid that the traces will be destroyed."

Chen Jing gave a thumbs up: "If you can be so cautious, if you don't eat the job of criminal investigation, it will really be a waste of talent."

Su Yang just responded with a smile, followed Chen Jing and Jiang Rou to open the toolbox and put on gloves and foot covers, and began to inspect the surroundings of Ashes.

It didn't take long for Jiang Rou to pick up a small lump of mud with tweezers, then illuminated it with a light and said with a bright smile, "Look what I found?"

With the help of the light, a hair mixed in the mud was particularly obvious.

Although that hair has been falling out here for a long time, it takes a long time for the hair to rot. At this moment, it can be seen that the hair color is very healthy.

Chen Jing approached the hair, looked at it and sneered: "Tsk tsk, how can such healthy hair be Mr. Wu's?"

"It can't be his, but it could also be the worker who cleans the sewer. It can even be on the edge of the ashes, so it still needs to be identified. In this way, Aunt Chen, take your hair away first and use the fastest time. After identifying the DNA of this hair, Jiang Rou and I continue to search here. This is the crime scene, and there must be more clues. "

Chen Jing nodded and left immediately with the hair, Jiang Rou and Su Yang continued to search.

But Jiang Rou seemed to have a purpose around Ashes, but Su Yang kept looking around.

Jiang Rou was so puzzled that she finally couldn't help but ask, "Team leader, what are you looking at?"

"I'm wondering where the murderer cut off Old Wu's head. It should be not far from the ashes. But is there any large bloodstain around it? It shouldn't be. Moreover, Old Wu's body is so clean that it can't even be seen. The clothes were not dirty, maybe it was because of the burnt oil paper wrapping. But there was sulfide sludge in his hands. Could the sludge really be caused by serving those vegetables?" Su Yang replied. .
