Chapter 11 Temporary Workers
Ninety-nine percent of the time, when the police solve a case, they cannot do as Sherlock Holmes did, who could deduce a host of possibilities from tiny details at a glance.
Those are all artistic processing of TV dramas and novels, to make people look cool and awesome.
In reality, the police have three tricks when investigating a case.
A dragnet-style investigation, a widespread manhunt to arrest people, and long and intense interrogations.
Later, with the advancement of technology, DNA technology, information networking and overwhelming surveillance, the efficiency of investigating cases has been greatly improved.
But now, in 1997, these three tools are still the most practical and reliable.
But the biggest problem with this crime-solving process is that it is extremely time-consuming and labor-intensive.
Zhou Yi remembered that the files of the 316 case clearly recorded that the police conducted a comprehensive investigation into Du Xiaolin's interpersonal relationships without any clues.
But the result is obvious, those who may have motives have sufficient alibis.
The person's alibi is insufficient and he has no obvious motive for committing the crime.
In the absence of key evidence such as fingerprints, footprints, and murder weapons, it is impossible to interrogate everyone.
Therefore, after checking interpersonal relationships to no avail, the police could only shift their focus of investigation to roving robberies.
Later, the case gradually reached a dead end.
Of course Zhou Yi couldn't make the same mistake again. Now he had to hurry and catch the murderer before he could recover from the shock and get rid of all the evidence.
Otherwise, given the murderer's meticulousness and caution, it might be difficult to deal with the case over time.
Wu Yongcheng discovered that the boy in front of him really had a sophisticated temperament that was not in line with his age.
His apprentice Chen Yan is two years older than Zhou Yi, but compared with Zhou Yi, he feels like a chick.
"Then what is your investigative direction?" Wu Yongcheng asked.
Zhou Yi scratched his head and said with a simple smile, "Captain Wu, I have a small request."
"Require?"
"I want to join the Criminal Investigation Division of the Municipal Bureau."
Zhou Yi's words surprised Chen Yan, but Wu Yongcheng seemed to have guessed his thoughts a long time ago.
"Why? Aren't we policemen serving the people no matter what position we are in?" Wu Yongcheng said calmly.
"Yes, that being said, if I could be a detective, I could save more lives."
Zhou Yi was not joking, because he had already formed a plan in his mind, but the first step to implement this plan was to join the Criminal Investigation Detachment of the Municipal Bureau.
"Snap." Wu Yongcheng took out the wrinkled cigarette box from his pocket again, took out a Daqianmen cigarette from it, and lit it with a lighter.
Then he exhaled a puff of smoke and said calmly, "I can give you a chance. If you can solve this case within 24 hours, I'll make an exception and temporarily transfer you here."
"temporary?"
"Nonsense, do you think I'm the director? I'm just a deputy captain. How can I cover up everything with one hand?"
Zhou Yi chuckled and said, "Captain Wu, do you mean that the director can cover up everything?"
"Hey, kid, you're threatening me. Just tell me whether you want to make this deal or not. If not, get out of here."
"Damn! A gentleman's word is his bond."
Chen Yan, who was standing by, chimed in, "It's hard to catch up with him."
Wu Yongcheng glared at Chen Yan, then said, "At the end of next month, the Criminal Investigation Detachment will hold an internal interview to select high-quality talents from various branches and grassroots organizations as a reserve to join the detachment. If you can be this temporary worker, you will have a much greater advantage in becoming a regular employee."
Zhou Yi immediately smiled. "Thank you, Captain Wu."
"Can you speak now?"
In fact, Wu Yongcheng already had a liking for talent in his heart, but he didn't expect that this guy would be so proactive.
It really proves the saying that opportunities come to those who are prepared.
Zhou Yi nodded: "Captain Wu, I have a suspicion that the murderer might be a woman."
Wu Yongcheng was stunned: "Woman? Did you see the murderer's appearance?"
Unexpectedly, Zhou Yi shook his head: "It was too dark, and the person was wrapped very tightly, so I didn't see any obvious gender characteristics."
"Then why do you suspect the murderer is a woman?"
Zhou Yi raised a finger. "First, although I can't see the features clearly, judging by the height and weight, it's either a short male or a female."
"Weight?" Wu Yongcheng was stunned. "How do you know the other person's weight?"
"From the feeling of the kick I gave him, I can basically tell that his weight is no more than 110 kilograms."
Chen Yan asked in surprise, "You can even sense this?"
Zhou Yi nodded: "It's about right."
Chen Yan turned around with a shocked expression and asked Wu Yongcheng, "Master, can you do this?"
"Ahem, this is actually not that difficult."
Wu Yongcheng looked at the calm expression on Zhou Yi's face and felt that he did not seem to be lying.
Is this something a young policeman who just started working at a police station can do?
Zhou Yi extended another finger.
"Secondly, when Forensic Doctor Xu was treating my wound, he said that the wound on my head wasn't as serious as I had imagined. It wasn't deep."
Chen Yan asked in confusion: "What does this mean?"
"This shows the killer wasn't very strong. If it was a strong, adult male, I'd have been killed by that brick."
Wu Yongcheng said, "These are just your subjective feelings. They're not without reference value, but I'm afraid they're not enough to determine the direction of the next investigation."
"I know, so I have another clue."
Last night in the hospital, after Zhou Yi paid the fee and picked up the medicine, he happened to overhear a brief conversation between two nurses when he went to deliver the medicine to the emergency nurses' desk.
——What’s wrong with this Du guy? Why did he get the medicine wrong again?
—Huh? Wrong again?
——If she doesn't want to do this anymore, just leave. What's the point of keeping her around to cause trouble for us?
——That’s right. Two months ago, we all had our bonuses deducted because of the wrong medicine. I was so angry.
——Luckily I checked it, otherwise something serious would have happened.
——I’ll report this matter to the head nurse tomorrow. It’s really unlucky to work with her.
It was just a few short words. At that time, Zhou Yi's mind was on his grandfather, so he didn't pay much attention to it.
Thinking about it afterwards, the person with the surname Du they were talking about was most likely Du Xiaolin.
After hearing Zhou Yi's words, Wu Yongcheng asked, "You mean... Du Xiaolin's relationships with her colleagues aren't good?"
Zhou Yi's real purpose was to avoid taking a detour, because the files of the 316 case recorded that the initial investigation direction was to focus on the two directions of love killing and revenge killing. Du Xiaolin's relationships with many opposite sexes were basically investigated thoroughly, but nothing was found.
So Zhou Yi wanted to bypass this conventional direction, but he couldn't say it directly.
Of course, this does not mean that the previous direction was necessarily wrong. Perhaps it was just that no useful clues were found.
"I think there are several clues here. First, Du Xiaolin's relationships with her colleagues were definitely not good, but having her bonus deducted due to being implicated is unlikely to be a motive for murder. So the more crucial factor should be Du Xiaolin's change."
"change?"
"Well, judging by what they said, Du Xiaolin's negative work attitude definitely isn't always the same. After all, she doesn't look like she's new to the job. If she'd always been so irresponsible, her colleagues wouldn't react so strongly."
"So I think the key is when did Du Xiaolin start to change, and why."
Zhou Yi said with a sharp gaze, "My intuition tells me that this must be the key to solving the case!"
