After committing a thousand perfect crimes, he joined criminal investigation

Chapter 50 Reverse thinking, the murderer reveals himself (please follow up)
  "Li Ruizhen's father?"

Faced with Gao Yi's inquiry, Sun Youmeng thought for a while, then rummaged through the information, and she actually found relevant information:
  "His father is a caterer."

"FOOD?"

Sun Youmeng just answered casually, but the moment Gao Yi heard the word "catering", a light seemed to flash in his mind.

Catering~
  Experience in slaughtering animals.

"That's right." Sun Youmeng nodded and continued: "After you and Wei Qiang left, Team Peng contacted the Yilan County Police, and a document was sent there ten minutes ago."

"This is it."

With that said, Sun Youmeng handed the information to Gao Yi.

"Li Guoqing applied for a catering license in 1999 and ran a [National Day Food Stall] in Nghe An County. He moved away three years later..."

Looking at the information displayed on the file, Gao Yi finally understood why Li Ruizhen had lived in Nghe An County for a period of time.

He must have followed his father into the catering business. After Li Guoqing moved away, there was no record of him doing catering, so he probably didn't continue the business.

It was at that time that Li Ruizhen came to Huai City to work hard.

Thinking of this, Gao Yi immediately asked: "Sister Meng, can you find out where Li Guoqing works now?"

"Yes, but this requires the help of local departments."

Sun Youmeng nodded, but said it would be difficult to find out in a short time.

If the other party has information about paying five insurances and one fund, you can quickly locate the company where the other party works.

But if it is a job such as a chef or a mason, most of them do not have five insurances and one housing fund.

In addition, if you want to lock the other party's IP address through their mobile phone number, you must know the other party's mobile phone number.

But nowadays, most mobile phone numbers do not have real-name systems, so it is impossible to check them.

So if you want to know where Li Guoqing is and what he is doing, you can only visit him at his home.

"You..." Sun Youmeng said, suddenly, she seemed to have thought of something, and looked at Gao Yi in surprise: "Are you suspicious of Li Guoqing?"

Gao Yi has raised a point before - the murderer may not have committed the crime alone.

So, is there really a second murderer when Li Ruizhen is highly suspected but does not meet the characteristics of the murderer?

Combined with the fact that Li Ruizhen lied about not knowing Diao Aiqing...

"I will call the Yilan County police and ask them to cooperate in the investigation of Li Guoqing!"

At this moment, Sun Youmeng picked up the phone and immediately called the Yilan County police.

At this time, Wei Qiang reported back.

"What did Captain Peng say?"

Gao Yi asked.

"Team Peng also thinks Li Ruizhen is very suspicious and asked us to focus on this person."

While talking, Wei Qiang came to Gao Yi, put his arm around Gao Yi's shoulders, and said hey, "You've never been out in the field before, right? Brother Qiang will give you a try this time!"

"Not really."

Looking at Wei Qiang's proud expression, Gao Yi smiled.

It is true that he has never been out in the field, but in order to complete the perfect crime, he once followed a target for half a month.

Of course, there are even more experiences of being followed.

"It doesn't matter, Brother Qiang will give you a long experience this time."

Wei Qiang naturally didn't know what Gao Yi was thinking, so he patted Gao Yi on the shoulder like a big brother.

"In addition, Team Peng will notify the communications team to monitor Li Ruizhen's phone calls."

Since Li Rui is really suspected, the focus of the next investigation will definitely be on the other party.

Therefore, whether it is tracking, monitoring, or investigating his social relationships, etc., it will all be carried out at the same time.

Gao Yi and Wei Qiang were arranged to follow Li Ruizhen.

So, after simple preparations, Gao Yi and the two left the police station and came to a road next to [Jia De's real estate].

Field work, especially tracking target persons, is actually not complicated. As long as they are not discovered by the other party, they can continue to track them.

If the person being followed notices it, just change someone immediately and continue tracking.

After discussing with Wei Qiang, Gao Yi decided to adopt this alternate tracking method.

The two were in contact at any time, and each followed for a period of time to ensure that Li Ruizhen would not notice anything unusual and achieve the purpose of tracking.

The effect is good. Gao Yi and Gao Yi were not discovered until Li Ruizhen returned to his residence that evening.

But at the same time, Gao Yi and Wei Qiang, who had been following for a day, found nothing.

Throughout the whole day, Li Ruizhen was either on the phone at the company or showing clients houses. Even lunch was eaten near the company.

It was so boring that Gao Yi almost fell asleep!

"This guy is really active in his work!"

At eight o'clock in the evening, downstairs in a certain building in Jiefang Community, Wei Qiang couldn't help but muttered as he looked at the lights in room 302.

"What?" Gao Yi glanced at Wei Qiang, with a smile in his eyes: "It's only been one day and you can't hold on anymore?"

"Who told you I couldn't hold on?"

Feeling the "contempt" in Gao Yi's words, Wei Qiang immediately puffed up his chest and explained:

"I just think this guy is so normal."

After a day of tracking, Li Ruizhen was in a normal working-class state.

Nothing unusual can be seen.

"If he is the murderer, I can only say that this guy's psychology is so strong that he is abnormal!"

With that said, Wei Qiang handed Gao Yi a bucket of instant noodles.

"I suddenly thought of a question..." Gao Yi took the instant noodles and suddenly frowned as he was about to take a bite.

"What's the problem?" Wei Qiang turned to look at Gao Yi.

Could it be that Gao Yi made a new discovery?

Just as I was thinking about it, I heard Gao Yi say:
  "What if Li Rui really has no problem?"

After investigating all the way, even Gao Yi felt more and more that Li Rui was really the murderer.

Even when there were discrepancies between Li Ruizhen's characteristics and the murderer's profile, the possibility of Li Ruizhen's father assisting in the crime came to mind.

But what if Li Rui really has no problem?
  This means that Gao Yi's initial investigation direction was wrong.

So let’s go back a bit—

Why did Gao Yi gradually think that Li Rui was really the murderer?

Association!
  It was precisely because he learned about the hometown association that Gao Yi noticed Li Ruizhen.

As the investigation deepened, Gao Yi began to believe that Li Ruizhen was Diao Aiqing's "writer friend", and found sperm spots in Li Ruizhen's residence, which further strengthened Gao Yi's idea.

So how did Gao Yi notice the hometown association?

"..."

Gao Yi's eyes gradually darkened, his brows wrinkled slightly, and he didn't know what he was thinking.

Jingle bell bell~
  I don't know how long it took, but Gao Yi was awakened by the ringing of his cell phone.

"It's Sun Youmeng."

On the side, Wei Qiang took out his mobile phone, looked at the number, said something to Gao Yi, and then answered the call:
  "It's me, Wei Qiang."

"Ok.

it is good.

I see. "

After a few conversations, Wei Qiang hung up the phone.

Seeing this, Gao Yi immediately asked: "Is there anything new?"

"Yes." Wei Qiang nodded: "According to reports from colleagues who investigated Li Guoqing, Li Guoqing and his wife have been working in Guancheng Garment Factory in recent years. Later, colleagues contacted the garment factory and confirmed that they had no absence records in the past half month."

In other words, Li Guoqing has not been to Huai City in recent years.

"Li Guoqing's line is broken."

Wei Qiang said, rubbing his sore head.

Now that Li Guoqing's line is broken, how can Li Ruizhen still investigate?

However, just when Wei Qiang had a headache, Gao Yi suddenly cast a serious look:

"Brother Qiang, I seem to know who the murderer is."
