Diary of a Criminal Investigator
Chapter 632: Key Clues About Zhang Yunxi
The investigation of the case seems to have hit a dead end.
The traffic accident case has made no progress, and the clues left by Song Jinfu have now disappeared.
And Zhao Xiaoguo, who was previously caught, is now retracting his confession.
He even demanded a psychiatric evaluation from a mental hospital.
Qin Yong doesn’t even need to think about it; if the police agree to the evaluation, Zhao Xiaoguo will definitely be diagnosed with mental illness.
Once Zhao Xiaoguo is found to be mentally ill, he might not be held criminally responsible for killing Song Jinfu.
After all, based on the current evidence, there is ample proof that Zhao Xiaoguo was coerced.
A mentally ill person being coerced; Zhao Xiaoguo might not have to bear any responsibility.
But does the case really end like this?
Fifteen years ago, there was the life of Zhang Manyu.
And three years ago, there was Zhang Yunxi, killed by Zhao Xiaoguo.
Adding to that, Song Jinfu and his wife.
Three lives, one person in a vegetative state.
If Qin Yong could let this case end here, he wouldn’t need to wear this police uniform anymore.
As for Zhang Yunxi’s death, Zhao Xiaoguo completely retracted his confession.
He said he remembered it wrong because he is mentally ill.
He doesn’t know anyone named Zhang Yunxi.
"Old Sun, you can go handle your tasks first."
After Sun Jun left, Qin Yong sat back in his chair, meticulously searching through the experiences of recent days.
From the current situation, the purpose of the person who called him back then is now very clear.
Their target was Zhao Guojun.
Qin Yong could even be certain that Zhao Guojun was very likely the murderer of Zhang Manyu back then.
And Song Jinfu was an accomplice at that time.
It’s just that besides Song Jinfu, there might have been someone else who saw Zhao Guojun commit the murder at the crime scene.
And this person is likely the one controlling everything and making the calls to Qin Yong.
Knock, knock, knock!
Just as Qin Yong was contemplating his next steps, there was a knock on the office door.
"Come in."
Qin Yong looked up and saw it was Lu Chuan and Liu Guodong.
"Captain Qin, we have a discovery!"
Lu Chuan and Liu Guodong looked very excited. They had indeed made a significant discovery in the diary.
Oh?
Qin Yong’s interest was piqued, "Tell me quickly."
Lu Chuan spread some photos he was holding on the table.
"While studying Song Jinfu’s diary, we found that when he wrote the entry for November 23rd, the pen marks bled through the paper onto November 24th."
"Then we used an ultraviolet light in the basement to illuminate the November 24th diary entry and found some traces."
"Although we couldn’t decipher all of them, some information was recognizable."
This time, Lu Chuan and his team managed to decipher about thirty characters.
Although they were scattered and incomplete, combined with these characters, they could essentially determine what Song Jinfu was writing about.
"Based on the meaning of about thirty characters, we reconstructed the passage and gained an initial understanding."
"The general idea is that when Zhang Manyu was killed, Song Jinfu was at the scene, and the murderer was Zhao Guojun. Song Jinfu helped Zhao Guojun dig a hole and bury Zhang Manyu."
"And apart from Zhao Guojun and Song Jinfu, there was a third witness at the scene, Zhang Manyu’s nine-year-old daughter, Zhang Yunxi."
Hmm?
"Are you saying Zhang Yunxi was at the scene and witnessed Zhao Guojun kill her mother?"
"That’s basically it. Although Zhang Yunxi was young, she should remember."
Lu Chuan and Zhao Guodong’s explanation was clear to Qin Yong.
The situation at the crime scene back then included the murderer Zhao Guojun, accomplice Song Jinfu, and only Zhang Yunxi witnessed the entire process.
This means Zhang Yunxi definitely knew where Zhang Manyu was buried.
So, the person who reported to Qin Yong was likely Zhang Yunxi.
"But Zhang Yunxi died three years ago."
"Yes, Zhang Yunxi was killed by Zhao Xiaoguo three years ago. She couldn’t have tipped us off this year."
"But... could Zhang Yunxi have told the secret to someone she was close to?"
"Someone close? Like Zhang Yunxi’s grandparents?"
"No, no."
Lu Chuan shook his head, "If Zhang Yunxi told this to Zhang Manyu’s parents, they might have reported it to the police back then."
"So, I suspect that the person Zhang Yunxi told the secret to might have been her boyfriend."
"Logically, Zhao Guojun is Zhang Yunxi’s father, and Zhao Guojun killed Zhang Yunxi’s mother."
"For all these years, Zhang Yunxi didn’t report it because the killer was her father."
"But three years ago, Zhang Yunxi died."
"Died at the hands of Zhao Xiaoguo, her half-brother."
"If Zhang Yunxi had a boyfriend... could he have orchestrated all of this to avenge her?" 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞
This assumption...
Damn, it’s actually possible.
"So, what do you mean?"
"I mean, we should investigate Zhang Yunxi’s connections."
"It might help us identify the person behind all this."
Lu Chuan’s speculation, truth be told, had a certain logic, but it seemed a bit far-fetched.
But considering other leads had dried up, pursuing this direction wasn’t impossible.
"Okay, for this matter, your Crime Scene Investigation team will have to put in some extra effort and investigate. The other teams are pursuing the traffic accident case involving Song Jinfu’s wife."
Liu Guodong and Lu Chuan had no objections.
If the action team could make a breakthrough, that would be ideal.
"By the way, during the investigation in the afternoon, Zhang Hui and the team found out that the driver’s daughter has a congenital heart defect, and it will cost 1.8 million to cure it."
"Lu Chuan, I want you to go and talk to that driver."
"The driver is currently stonewalling us, likely because the other party is leveraging his daughter against him."
"If his daughter were out of the woods, I think he’d be more likely to confess."
"Sure, leave it to me."
In terms of interrogation skills, Lu Chuan was average and couldn’t compare to Zhang Hui’s team.
But when it came to throwing money around, not even a hundred Zhang Huis could compete with one Lu Chuan.
The investigation into Zhang Yunxi couldn’t be rushed; Liu Guodong, Old Bai, and Yang Sen had much more experience in this area than Lu Chuan.
So, the four split into two groups: Lu Chuan went to have a chat with the driver.
Liu Guodong led the effort to investigate Zhang Yunxi’s background.
Interrogation room.
As soon as Lu Chuan sat down, the driver across from him spoke up.
"Officer, you don’t need to waste your time on me. I don’t know anything. It was just a traffic accident."
"No one instructed me, and no one gave me money. You can sentence me however you want; I’ll accept it."
After saying this, the driver hung his head and refused to say anything more.
