1995, Starting as a Criminal Investigation Expert

10 month 25 number.

Today is the third day of the National Games, and as a sub-venue, Nanjiang has finally welcomed its competition events.

Strolling through Nanjiang city, one can easily see the slogan "Develop urban sports and improve the quality of the Chinese nation".

Tingyang, No. 82, Houchai Lane, Baizhuang Village.

Tan Guoxiong and his two companions knocked on the door.

A woman opened the door.

It was late October, and the weather was already cool, even though it was broad daylight. She was wearing a pink, lace-trimmed slip dress and had a trendy perm. She asked the group what they were doing.

Tan Guoxiong instinctively averted his gaze, knowing that it was indecent to look at.

After cursing, Xu Qiang decisively followed Li Shu's advice and re-screened the nearly two hundred people who had been investigated last year.

They went to their home to collect their fingerprints.

This required the assistance of technical personnel, so Li Shu, Tan Guoxiong, and others went out together to collect fingerprints.

One person from the main brigade and one person from the local branch office were assigned to each group of three.

My colleague from the first team, Sun Lifei, showed his identification first.

Upon seeing the witness documents, the woman, who had been acting nonchalantly, instantly stood up straight and a smile spread across her face.

Sun Lifei frowned slightly and asked if Zheng Cheng was there.

During the investigation last year, many people reported that Zheng Cheng and Huang Youjun were friends for many years and had a good relationship.

"My brother Zheng is here, he's here."

The woman quickly moved aside and turned to shout a few times into the house.

The three went inside and waited for almost a minute before someone came out from the inner room.

He had a square face, a trendy side-parted hairstyle, and was buttoning his shirt as he walked, greeting everyone with a smile before asking, "Officer, what's up? Is there something you need?"

Sun Lifei clutched his bag and explained the situation, but his gaze remained fixed on the woman.

The woman huddled up next to Zheng Cheng, her gaze somewhat evasive.

Zheng Cheng was taken aback and asked curiously, "Officer, didn't we investigate last year? I really did go to Yuehai; I even showed you my train ticket."

The reason Zheng Cheng was ruled out during last year's investigation was because he went south to Yuehai to purchase goods during the time period of the incident.

There was no opportunity to commit the crime.

Sun Lifei didn't explain, saying, "Don't worry about that. I'm here today to have you cooperate in collecting your fingerprints."

Zheng Cheng was stunned for a moment.

Sun Lifei said in a deep voice, "What, you're unwilling?"

Zheng Cheng quickly shook his head and said, "I'm willing, I'm willing. Anyway, it has nothing to do with me, so what am I afraid of?"

Then he asked how to pick them.

Tan Guoxiong took the ink and stepped forward, demonstrating it to Zheng Cheng and pointing out the key points of the collection.

Zheng Cheng did as instructed and succeeded in one go.

"That's settled then. Don't wander off lately, I might need to look for you again." Sun Lifei said, his gaze sweeping over the woman before finally looking away.

Before they had taken two steps outside, Tingyang's colleague turned around and saw the door was closed. He whispered, "Old Sun, that woman is a prostitute, isn't she?"

Upon witnessing the case, the reaction was entirely instinctive.

And throughout the whole process, he was evasive and dodging, clearly having something to hide.

Sun Lifei nodded. Dressed so flamboyantly in broad daylight, one could imagine what he was up to.

However, information gathered last year indicated that Zheng Cheng was single and unmarried.

It's normal to hire a prostitute then.

The main problem is that I still have to travel to several places, and I'm too lazy to deal with these trivial matters.

Just as he was about to call Tan Guoxiong to get on the motorcycle, Tan Guoxiong stopped in his tracks, holding a magnifying glass in one hand and the fingerprint card he had just collected in the other, looking at it intently.

He was called out, and he looked up abruptly, his expression one of shock.

"Holy shit!"

Upon seeing his reaction, Sun Lifei exclaimed in surprise, his scalp tingling instantly, and he said urgently, "Could it be that they've matched up?"

Tan Guoxiong hurriedly said, "No, don't worry, I just feel like it. Let me take another look."

Sun Lifei, a veteran criminal investigator, quickly beckoned Tan Guoxiong to get in the car and go a little further away.

You can see this side from Zheng Cheng's house.

The three of them immediately got into the sidecar, drove for more than ten meters, and stopped against the wall.

Sun Lifei had already deftly pulled out a pistol from his bag, turning his head warily to look back in the direction of Zheng Cheng's house while nervously watching Tan Guoxiong.

Tan Guoxiong took a magnifying glass and examined the fingerprint card closely.

Tingyang's colleague also pulled out a pistol and asked if he wanted to call the team.

"Don't rush."

Sun Lifei shook his head, staring intently at Tan Guoxiong.

Tan Guoxiong was both nervous and excited, staring intently at the fingerprint card and silently counting.

It's not about looking at one fingerprint, but at all fingerprints.

It's not about looking at all the features of a fingerprint, but rather at the most obvious and easily distinguishable features.

Then look at each finger one by one.

There might be exceptions if you match one or two fingers, but if you match several fingers, the probability is extremely low, so you can't be wrong.

This is also learned from Li Shuxue, which is the fastest way to distinguish whether it is the same fingerprint.

Soon, Tan Guoxiong looked up and nodded eagerly.

Yes, the obvious features of both hands match.

"Holy shit!"

Sun Lifei let out another low exclamation and hurriedly asked Tingyang's colleague to make a phone call, first to the branch office, then to the municipal office.

He got out of the car himself and let Tan Guoxiong drive the motorcycle back directly.

Tan Guoxiong hesitated for a moment, then said, "Old Sun, I'll stay. I brought a gun too."

Considering that collecting fingerprints might alert the suspect, the accompanying technicians were also temporarily armed for safety reasons.

"Besides, we just collected fingerprints. Could we have alerted him? If I drive the motorcycle away, what if he runs away? How am I supposed to catch him?" Tan Guoxiong added.

Sun Lifei quickly recalled the collection process.

Zheng Cheng's reaction was not unusual.

But what if it's fake?

Moreover, the fingerprints matched, and Zheng Cheng is the murderer. Now that he's come to collect his fingerprints, he'll definitely be on guard.

Sun Lifei said, "Okay, drive your motorcycle a little further away and wait for us."

Tan Guoxiong nodded and drove the motorcycle onto the road outside.

Tingyang's colleague, Ning Hualin, hurriedly returned after making the call. The two huddled in a corner, peering tentatively at Zheng Cheng's house in the distance.

You can see the main entrance.

Ning Hualin said, "Old Sun, this place is very interconnected. What if he tries to escape through the back door?"

Many houses here have back doors; if you run out through the back door, you won't be seen at all.

Sun Lifeng gripped his pistol, his brow furrowed, and said, "How about this, I'll go around to the back door and guard it."

Ning Hualin quickly stopped him, saying, "Let me go, I know this area well."

He looked around and quickly ran towards the path opposite.

At this time, Zheng Cheng was at home.

In the inner room, Zheng Cheng pulled a box from under the bed, opened it, and found several stacks of cash inside.

He hurriedly stuffed it into his bag.

Beside him, a woman stood trembling, her face deathly pale.

After putting the cash in, Zheng Cheng quickly opened the wardrobe and pulled out a Type 56 assault rifle from the bottom pile of clothes.

This gun is a copy of the AK, with powerful firepower and high reliability.

In earlier years, these items were widely held by civilians, especially militia members, and their loss was a serious problem.

Moreover, the gun's structure is not complicated, and there are many imitations made by civilians.

"Brother Zheng... Brother Zheng, you..." Upon seeing the submachine gun, the woman's legs went weak. She pressed herself against the wall and stammered, "Brother Zheng, you won't... kill me, will you? Don't worry, I won't tell the police anything."

In front of Sun Lifei and the others, Zheng Cheng was all smiles and looked particularly honest.

At this moment, only a cold expression remained on his face.

He silently loaded the magazine, pulled the bolt, and then crept closer.

"My dear, I love you so much, how could I bear to kill you?"

He leaned in close, stuck out his tongue, and licked the woman's face.

The woman closed her eyes, too frightened to move.
