I'm a street kid, but my wife, a policewoman, won't divorce her

Chapter 735 Two tears!
Traces are a very important subject in criminal investigation.

Even though it's just a common thing to do in solving crimes.

However, in the eyes of a true trace expert, there is much more than just bloodstains, footprints, fingerprints, movement of objects, etc.

A true trace expert is someone who can connect all the traces to the psychology of the person who created them.

Qin Fei's words "he looked back" were exactly what Chen Xiao had deduced based on those traces.

It's just a sentence that he turned back, but it's not the real point.

Chen Xiao pointed at the murderer's last footprints at the crime scene and said, "Look at this circle of traces. Can you tell anything?"

"He looked back, and more than once. There is a high probability that he stayed in this place for a long time." Qin Fei expressed his opinion.

Chen Xiao nodded, but before he could say anything, Qin Fei had already thought of a situation that had occurred before:
"Could it be that he picked up the alarm text message sent by Ye Jun's mobile phone at this time?"

Chen Xiao glanced at him and said with a smile: "Recall the traces around Ye Jun carefully."

After his reminder, Qin Fei, who was not good at observing traces, found the point in his memory in the fastest time.

"It's you again. I thought I looked very carefully just now, but I didn't remember the deep meaning of each footprint."

Chen Xiao didn't dwell on these things, and after standing up, he said:

"There are footprints of him pacing back and forth beside Ye Jun. These may be left by him when he called the police."

"As for what we are seeing now, it is what he left behind in his final moments. He turned back, and he did so more than once or twice."

"The main thing is, look at these two little dots, what do you think caused them?"

Chen Xiao pointed to two irregular dots left on the wall not far from the footprints.

Seeing these two dots, Qin Fei's eyes subconsciously lit up, but soon he became confused again, and even couldn't help muttering:
"No way, this is impossible?"

Looking at Qin Fei mumbling to himself with a look of horror on his face, Chen Xiao asked calmly:
"Who did you think of?"

"I, I thought of... Ye Changhuai! These two dots should be the result of uncontrollable tears falling into his hands and hitting the wall."

Qin Fei expressed his thoughts.

Chen Xiao gave a thumbs up: "It could very well be him, but it could also be someone else."

"From what we've seen of Ye Jun, maybe his academic performance isn't that good, but he's a very smart person."

"And now I can see from the traces at the scene that the person who killed him was reluctant to leave at the end, and most likely cried about it. So, the first thing that comes to mind is naturally Ye Jun's family."

"He only has two real relatives, one is his father and the other is his mother. But his mother is a mentally ill woman, and the footprints at the scene can also be seen as a man's footprints."

"So, if we choose one of the two, Ye Changhuai is more reasonable."

"But why do I say it's not limited to Ye Changhuai? Because we don't know enough about Ye Jun's other relationship, which is about his studies."

Qin Fei suddenly realized and nodded repeatedly:
"Indeed, we need to connect him to any relationship with the deceased! In addition to his family, there is also his school!" "Well, this case is now very clear. It is the assassination of Professor Yuan Keyu by foreign forces. But their choice of assassination is to create enough difficulty in criminal investigation."

"Such assassinations will make people think that this is a homicide at first, rather than involving other acts, thus better concealing their true intentions."

"Foreign forces are treated as a knife by Ye Jun, who can be discarded after use. The person holding the knife may come from Ye Jun's circle of connections..."

Chen Xiao said, then stared at Ye Jun intently and said:
"The people who killed him mistakenly thought that by killing him, all the secrets would be protected. Unfortunately, he left the most fatal flaw when he killed Ye Jun."

Qin Fei thought for a moment and said, "I will call my colleagues stationed in Xiaozhuang South Town right away and ask them to find Ye Changhuai immediately and find out his whereabouts tonight. If he is not in Xiaozhuang South Town, then it could be him!"

Chen Xiao didn't say anything, but nodded to agree with Qin Fei's approach.

Soon, Qin Fei made a phone call.

But when Qin Fei took out his phone, Chen Xiao suddenly stopped him:
"Wait, I'll go back."

"You're going back?"

"Yes, more information about Ye Jun's circle of friends should be delivered at the moment. I have also examined Ye Jun's body, and I have memorized everything I saw at the scene, so there is no point for me to stay in Zhushan City."

"Instead of staying here, why not wait for them halfway!"

"How?"

"Although Zhushan and Xiaozhuangnan Town are not far apart, it still takes time to get there. Ye Jun is Ye Changhuai's son. As the police, since we know about his death, we have an obligation to inform him!"

Qin Fei quickly said, "I understand. The fastest way from Xiaozhuangnan Town to Zhushan City is to take the highway. If you don't see him at the highway intersection, it means he is definitely not in Xiaozhuangnan Town."

"Even if he said at the end that he came from another route, what father would deliberately take another route to Zhushan City when he learned of his son's death?"

Chen Xiao nodded: "I will leave now, and then I will call Ye Changhuai at the highway exit to confirm where he is first, and then use the time to determine whether he is really in Xiaozhuangnan Town."

"In addition, whether I have met Ye Changhuai or not, I will leave Zhushan and rush back to Xiaozhuangnan Town within a reasonable time. Going back to Xiaozhuangnan Town is also an extremely important matter."

Qin Fei was a little puzzled: "Why? What if there is no one suspicious in those relationship data?"

"Information is only one part of the story. Another more important point is that the other person might not come to Zhushan City right away. Ye Changhuai and Luo Mei are a loving couple. If a man learns of the death of his only son, he may not necessarily tell his wife right away."

"Especially since his wife is mentally ill and loves Ye Jun very much! So, what we need to do is to get a clear grasp of their whereabouts!"

After saying this, Chen Xiao sighed deeply:

"If someone else committed the crime, then we can only continue to investigate slowly, and we can no longer take advantage of the situation!"

After leaving these words, Chen Xiao did not stay at the crime scene any longer.

After taking the key from Qin Fei's hand, he immediately ran straight to the highway exit!
