Because the place where they talked to Yang Chengming before was still more than ten meters away from here, and it was still a bit noisy, even normal young people might not be able to hear their conversation at this distance.

"At the beginning, after the case was decided, I left the special case team. I have been waiting, and the people from the special case team came to me, but I didn't expect to wait for ten years. I thought I would leave this world with regrets! Yang Lao sighed and said.

When we heard Yang Lao's words, we couldn't help but feel a little surprised in our hearts.

Judging from the current situation, Yang Lao seems to really know something.

"Elder Yang, did you suspect that the murderer was someone else ten years ago?" Chen Fei immediately asked.

Elder Yang nodded, and then said, "At the beginning, it wasn't just me who doubted, but your master also had doubts. It's a pity that after I caught the first suspect and had sufficient evidence, I forced us to convict us. ”

"At that time, all the members of the special case team had always been very concerned about this matter and secretly investigated it themselves. It's a pity that nothing was found, and all the evidence pointed to the suspect. ”

"In the end, I left the special case team, your master also left, and everyone else left."

"This case will no longer be cared about, and it may have long been forgotten by everyone."

"But I never forgot it."

When Yang Lao said this, he couldn't help but clench his fists slightly, as if he was very dissatisfied with the verdict at that time.

"Elder Yang, now that the case from ten years ago has been reopened, if you know anything, please tell us, it may become the key to overturning the case." Chen Fei hurriedly said.

"After the verdict was confirmed, I carefully examined the body again, and I did find something. It's a pity that the case was already finalized at that time, and the people above were not allowed to continue the investigation. ”

Yang Lao sighed and said: "The victim ten years ago may have suffered a second violation, but the second time he took safety measures and did not leave the other party's germ cells. ”

"Elder Yang, are you sure?"

When I heard this, I immediately asked.

Hearing this, Old Yang raised his head slightly to look at me and Ouyang Yanyan, and then asked, "You two are new?" ”

"Elder Yang, this is Sun Ming, not a member of the special case team, but a little detective in Haicheng. This is Ouyang Yanyan, a newcomer to the special case team. ”

Chen Fei immediately introduced.

"You are the Sun Ming who has recently been known as the Haicheng Detective?" Yang Lao looked at me with some surprise.

"I'm just a detective in a detective agency, not a detective, it's just a title given by others." I smiled a little awkwardly.

In front of a senior, he didn't dare to be called a detective.

Hearing this, Yang Lao only nodded slightly, did not say anything, and then continued: "After repeated examinations, I found some silicone oil in the victim's body. ”

"I see."

I nodded, and it was indeed surmising that there might have been two aggressors.

If there is only one aggressor, why not take security measures and leave evidence for the police if there is only one aggressor?

"What is silicone oil?"

Ouyang Yanyan asked with some curiosity.

"You'll find out for yourself."

I replied casually, without explanation.

"Elder Yang, have you found any other clues?" I asked again.

"The other party's method of killing is very high, killing with one knife, if it is not a frequent offender, then it may be a butcher, and he knows the structure of the human body very well." Yang Lao said again.

I listened to Elder Yang's words and fell into deep thought.

"There are no other clues other than these clues, and after ten years, it is difficult to find other clues."

"I know of the same case that happened recently, but it was said to be a suicide case."

"But the appearance of this case also makes me more sure that the murderer must have someone else ten years ago, but it's a pity that I'm old, so I can only hand it over to you young people to solve the case."

After Yang Lao finished speaking, he stopped talking.

We didn't ask anything more and left the nursing home.

"Sun Ming, have you found anything?"

After leaving the nursing home, Chen Fei asked me.

I shook my head helplessly, there are too few clues I can grasp at present, and ten years have passed, even if the murderer is found, it is difficult to find evidence.

"I want to go to Li Aihua's house again."

I thought about it for a moment and said suddenly.

I always feel that something is not quite right with Li Aihua, and it seems that only in them can it be possible to find more clues.

Li Aihua suddenly skipped work on the night the victim was killed, but when he came back, he was very drunk, and he was the first person to discover the scene of the murder, which is also extremely suspicious.

If it's just a coincidence, it's too much of a coincidence.

If it is not a coincidence, then there must be something in it, an unknown secret.

The key breakthrough may also be on Li Aihua's body.

"Go to Li Aihua's house again?"

Chen Fei was slightly stunned, then shook his head and said, "Sun Ming, forget it!" It's not too early today, I'll talk about it tomorrow, I'll send you back first! ”

When I heard Chen Fei's words, I looked up at the sky, only to find that the sun had already set, and the sky was already a little dark.

"Okay!"

I nodded, and I had to continue tomorrow.

When I got home, I started sorting out all the information I had learned today.

These clues may seem intermittent, but they all seem to be related.

"According to these clues, Li Aihua's suspicion is indeed the biggest, and the breakthrough may also be on him."

"What about Zhao Zhengyu's ex-girlfriend?"

I suddenly thought of Zhao Zhengyu's ex-girlfriend, who also seemed to have a motive for committing the crime.

Although it was Zhao Zhengyu's girlfriend at the beginning, let her go to the appointment, it does not mean that she can accept that her boyfriend has a relationship with other women.

It is also possible to kill in love, but from the perspective of the modus operandi, it is unlikely.

It is not easy for a woman to use a fruit knife to pierce a person's body, unless she is lucky enough to avoid a bone and go straight through the heart.

"Whether it's possible or not, I have to find Zhao Zhengyu's ex-girlfriend and ask about it."

I thought about it, then took out my mobile phone and called Chen Fei.

"Sun Ming, call me so late and find a new clue?"

As soon as the phone was dialed, Chen Fei's voice came.

"No, I just want you to check someone."

"Who?"

"Zhao Zhengyu's ex-girlfriend."

"We have already checked this, Zhao Zhengyu's ex-girlfriend is called Yang Yingying, she is not in Haicheng at present, she married Qingcheng. I've sent someone to look for it, and I should be able to find it soon. ”

"Do you have anything else?"

"It's gone!"

"That's hanging, I'm tired for a good day's rest, and there will be a tough battle to fight tomorrow!"

"Hmm!"

After I finished speaking, I hung up the phone and looked at the time again, it was already eleven o'clock in the evening.
