Diary of a Criminal Investigator
Chapter 618: A Case Full of Doubts
"First, focus must be placed on the investigation within Spring Breeze Lane to determine who Song Jinfu was in contact with before his disappearance, whether he received any calls, and if he met with anyone."
"Second, check all the surveillance near Spring Breeze Lane, as well as the cameras near the main road at Bolida Warehouse."
"Find the two cameras with the shortest distance on the main road, assess the passing time, and investigate all vehicles passing through at unusual times one by one."
"At the same time, compare with the vehicles captured by the cameras near Spring Breeze Lane."
This work arrangement by Qin Yong caught everyone’s attention.
This method is excellent.
What can be confirmed now is that the murderer took the deceased Song Jinfu into Bolida Warehouse, undoubtedly by car.
Although the other party was very cautious, covering the tire tracks on the cement road leading from the warehouse to the main road.
However, since the other party used a vehicle, there must be clues left behind.
Such as surveillance footage.
There must be surveillance on the main road connected to the outside of Bolida Warehouse.
As long as we search all vehicles passing through during the time of the crime, the car driven by the murderer must be among them.
And by finding the two closest cameras on the main road, if it’s a vehicle passing through normally, the passing time should be relatively fixed.
But the murderer is different; the murderer took time to commit murder, so the time spent at Bolida Warehouse must have been relatively long.
Therefore, regardless of whether the murderer returned the same way or took a new path, as long as the time interval of vehicles within the surveillance period is long, the scope can be narrowed down.
The time frame in question is from 9 a.m. to 3 p.m. the day before yesterday.
Although the traffic is relatively high on the main road near West Mountain’s Bolida Warehouse, the investigation is still relatively easy.
With the surveillance near Spring Breeze Lane, comparing the same vehicles appearing on both surveillance cameras could likely provide cross-referencing information to directly identify the suspect’s vehicle.
The case analysis meeting soon concluded.
Action Group One and Action Group Two set out in different directions to pursue different leads.
After leaving the meeting room, Lu Chuan also returned to the Crime Scene Investigation office.
Lu Chuan had no questions about Qin Yong’s arrangement.
And from the current perspective of handling the case, Qin Yong’s arrangement is undoubtedly the best solution.
Although this lead to West Mountain’s Bolida Warehouse was discovered on Zhang Manyu.
But there have been no valuable clues from the burial site where Zhang Manyu died 15 years ago.
Therefore, Qin Yong understandably focused all investigative efforts on the murder of Song Jinfu.
After all, in Qin Yong’s view, as long as the reason for Song Jinfu’s murder is found and the suspect apprehended, everything will be solved.
But Lu Chuan didn’t see it that way.
The murderer having killed Song Jinfu is definitely not the goal.
The reason is simple: if the murderer only wanted to kill Song Jinfu, there was no need to make an issue with the remains of Zhang Manyu, who died 15 years ago.
Nor was there any need to tear up and place old newspapers in Zhang Manyu’s clothing pocket one or two years in advance to provide clues for the police.
The murderer could secretly and silently kill Song Jinfu, but if it was just to kill Song Jinfu, there was no need to do these extra things.
Then what is the murderer’s ultimate goal?
Is it to find out the truth of Zhang Manyu’s murder?
But it doesn’t seem so.
Even though Zhang Manyu disappeared and was murdered 15 years ago, the murderer was able to accurately locate where Zhang Manyu was buried, which means the murderer likely knows who killed Zhang Manyu back then.
If the murderer wanted to avenge Zhang Manyu, it wouldn’t have taken so much effort, let alone waiting 15 years.
The murderer could have directly killed the person who harmed Zhang Manyu.
But the murderer didn’t do that; instead, clues about killing Song Jinfu were left on Zhang Manyu.
From Lu Chuan’s perspective, it seems the murderer intentionally guided the police in a certain direction.
But since killing Song Jinfu isn’t the goal, and avenging Zhang Manyu isn’t the goal either, then what exactly does the person want to do?
Why bring the police into it?
Because once a mistake is made, he could easily be captured by the police.
At that point, no matter what the goal is, everything would be for naught.
Old Bai and Yang Sen saw Lu Chuan return with a troubled expression in the Crime Scene Investigation office.
"What’s up? Finished the meeting?"
Lu Chuan nodded: "Captain Qin made quite a detailed plan. If successful, I believe the suspect will be apprehended soon."
Lu Chuan wasn’t exaggerating. Although the other party was meticulous, there are some things that cannot be erased by human interference.
"Brother Bai, I have a question..."
Sitting at his desk and taking a sip of tea, Lu Chuan shared his recent questions with Old Bai and Yang Sen.
"I can’t understand why the murderer did this. Why go through so much trouble?"
Lu Chuan’s confusion wasn’t just about the murderer’s behavior; he was also puzzled about the person’s psychological behavior.
Because from the perspective of criminal psychology, murderers often kill for revenge, money, etc. In short, there must be a reason.
Even if some suspects commit impulsive murders, seemingly without purpose, it’s ultimately to satisfy a perverted psychological need.
But some actions of this suspect are baffling.
Old Bai lit a cigarette, thinking for a moment: "What’s there to be confused about? In my opinion, the main purpose is related to the cases surrounding Zhang Manyu’s murder."
Oh?
"Why do you say that?"
"Think about it. It’s been 15 years since Zhang Manyu was murdered, and the other party has long known the burial site. Why hasn’t it been revealed earlier?"
"It’s simple: either they don’t know who the murderer is, or they didn’t have the ability to bring the murderer to justice."
"As for why the case involved Song Jinfu... Lu, have you noticed that both Song Jinfu and Zhang Manyu worked at Experimental Primary School 15 years ago?"
Ah?
Old Bai’s words struck Lu Chuan’s mind like a flash of lightning.
Indeed, Song Jinfu drove at Experimental Primary School 15 years ago, and Zhang Manyu was a substitute teacher there at the same time.
They both had workexperience at Experimental Primary School. Is this a coincidence?
In ordinary cases, it might be considered a coincidence, but in this murder case, such a coincidence is certainly not a coincidence.
Undoubtedly, Zhang Manyu and Song Jinfu knew each other 15 years ago.
But what kind of entanglements did they have?
Could Song Jinfu have been the one who killed Zhang Manyu back then?
But if that’s the case, some things don’t add up.
So many years have passed since Zhang Manyu’s murder, and who would be avenging her now?
