Solving the case: Wu Song travels back 97 years and becomes a detective

"Hmm..." Hao Jianlin paused for a few seconds, "The cat scratched and bit, sometimes scratching and sometimes biting."

"..."

If you're going to make up a lie, at least make it believable.

Wu Song was too lazy to pay any attention to Hao Jianlin.

"Let's have the forensic team take photos and collect evidence, then have the forensic doctor issue a wound examination report, draw blood for DNA testing, and look at these shoes—these are all irrefutable evidence!"

……

Secure this entire chain of evidence.

Wu Song, Cao Dahua, and the pre-trial team sat opposite Hao Jianlin and officially began the interrogation.

"To be honest, I think you're pretty boring," Cao Dahua laughed. "Besides wearing gloves, leaving a ton of evidence at the scene, and being caught here, what's the point of you still stubbornly sticking your guns? What? You dare to do it but not admit it?"

"I really didn't do it."

"Do you know why I drew your blood just now? The murderer was scratched by Hao Min, and there was the murderer's blood and skin tissue under Hao Min's fingernails."

"Blood type test?" Hao Jianlin asked tentatively, then immediately added, "Maybe I have the same blood type as the murderer, but that doesn't prove I'm the murderer! There are only a few blood types, you guys are just messing around."

"Test your DNA," Wu Song said. "That is, your genes. Like fingerprints, each person only has one set. If your DNA matches the DNA left at the scene by the murderer, then you are the murderer."

"What A? I'm uneducated. You police can't take advantage of me because I don't know this and try to trick me into taking the blame for the murderer!"

"Believe it or not, as long as the DNA matches, we can convict you even if you don't say a word. You'll be punished for it, you understand."

"You dare to do it but not admit it, you coward. You've been a coward your whole life, and you're still a coward on your deathbed," Cao Dahua said with a sneer. "It's really fucking weird. I don't know how a coward like you dared to kill someone."

"So, I really didn't kill him, you've got it all wrong."

Hao Jianlin remained defiant.

But being stubborn won't help.

Tests revealed that the scabbed marks on Hao Jianlin's arm were caused by someone scratching him.

The test results of the shoe soles can also be matched with the footprints found at the scene.

In addition, the white work gloves were also found during the search of Hao Jianlin's house.

Despite this evidence, Hao Jianlin still refused to admit it.

Nobody's in a hurry. If they're unwilling to admit it, then we'll interrogate them every day until they do.

Besides, the DNA is being compared, and if the DNA matches in the end, it won't matter whether Hao Jianlin admits it or not.

The evidence is overwhelming, and it was premeditated murder; it's enough to warrant the death penalty.

……

8 month 15 number.

The DNA comparison results from the province are in.

Hao Jianlin was the one who was scratched by the deceased and also assaulted her.

Both match up, essentially ruling out the possibility that one person committed the murder and the other committed the assault.

At this point, the evidence is truly irrefutable.

Wu Song and Cao Dahua then interrogated Hao Jianlin again.

"This is the last time we'll interrogate you. If you don't want to confess, we won't force you, and we won't interrogate you again. Take what you want to say to the underworld." Cao Dahua placed the DNA comparison report in front of Hao Jianlin. "You can see with your other eye, right? You can read, right? Do you recognize this line of text and how do you read it?"

"Does this thing really work?"

"Do I need to explain this to you?" Cao Dahua sat back down, chuckled, and pointed a finger at Hao Jianlin. "You, you, just keep hiding your head in the sand! Goodbye!"

Cao Dahua got up and left.

Wu Song, along with the pre-trial personnel and the recorder, quickly got up to leave.

"Wait!" Hao Jianlin glanced at Cao Dahua. "I killed him."

"Are you willing to talk now?"

"Um."

"Then tell me!" Cao Dahua sat back down. "Why did you kill him?"

"I don't have any grudge against him, I just feel uncomfortable. I've lived for over fifty years, and I've been single for over fifty years. I can see my coffin lid in the future. But Jianhui, he has both a son and a daughter, which is fine, but his daughter is too good at studying. She's beautiful and academically excellent. Almost everyone in Yuantou Town is saying that the girl will definitely get into a good university, and Jianhui will enjoy endless blessings in the future. Why should he?"

Hao Jianlin said excitedly.

"I'm practically in my coffin, and he's always been better off than me, but how can he be even better off? I just can't understand it! Everyone says Jianhui can live a good life because of his daughter, so I'll kill his daughter and see what he does then."

That day I heard that his son was sick and needed to be hospitalized, so I knew that his daughter must be home alone. I heard that the police can detect fingerprints during investigations, so I specially wore gloves and waited at his door.

But I waited and waited, and he didn't come. So I walked along that path towards the school and happened to run into his daughter on the deer. I dragged her in and smothered her. But I was afraid you'd guess we had a grudge, so I did *that*, pretending someone had taken a liking to his daughter and did it. After that, I went home and stayed there until you came looking for me…”

"You're a real beast!" Cao Dahua glared angrily at Hao Jianlin. "Look at your statement. If there are no problems, sign and put your fingerprint on it."

Even without obtaining a confession, it was enough to sentence Hao Jianlin.

However, the investigation of this case was not handled perfectly.

With Hao Jianlin's confession and detailed account of the crime, the case can now be definitively concluded, leaving no room for further controversy.

When Wu Song and Cao Dahua returned to the Third Squadron's office and explained Hao Jianlin's motives for the crime, the other members of the Third Squadron looked at each other in bewilderment.

You look at me, I look at you.

Finally, Ma Dazhi said incredulously, "Is this guy crazy? Your relative's daughter is doing well in school, what are you so jealous of? To go so far as to kill someone? There are plenty of people who are better off than you, why don't you just kill them all?"

"That's just how some people are. They're not envious of those far away from them doing well, but if someone close to them is doing well, or even just about to have a good life, then it's like they've killed their own father." Ma Xiaowu clicked his tongue. "To be honest, I know we definitely didn't arrest the wrong person; it was Hao Jianlin who did it. But I thought it was because their two families had some kind of feud—the victim's parents didn't remember, but Hao Jianlin did. I never imagined it would be because of this!"

"Jealousy! It's a terrible thing." Ma Dazhi shook his head. "It's better for me to just live my life honestly. No matter how well you live, I won't be jealous."

"This case, even though only one person died, makes me feel even worse than the previous armored truck robbery." Liu Shutong frowned, shook his head, and finally sighed.
