It appears that the murder was premeditated.

At this moment, Jiang Xiaobai suddenly ran from a distance, and shouted as he ran: "Fang team! There is a major discovery!"

Chapter 96 Serial Killing? [fourth more]

Everyone looked at Jiang Xiaobai who was running.

At this juncture, any discovery could move the case forward.

Jiang Xiaobai didn't seem to stop along the way, panting, holding a red silk scarf on his white gloved right hand.

It was the one that fell on the dead man at the scene.

Fang Ze glanced at the silk scarf on Jiang Xiaobai's hand, and said, "Tell me what you found."

After taking a few breaths, Jiang Xiaobai said, "I visited all the shops in Tianlai Manor, and there is a place that sells this kind of silk scarves. They are exactly the same, and the brand is also the same."

"And the boss said that there was a person wearing a hat and mask who asked him to buy five pieces a day ago."

As soon as these words came out, everyone's hearts tightened.

Especially for a criminal policeman like Ding Chunqiu who has been handling cases for many years, his complexion immediately turned serious.

"Are you sure this silk scarf came from that... store?"

Ding Chunqiu asked a question.

Jiang Xiaobai said: "It's just exactly the same. As for whether it is one of the five, I can't be sure, but the possibility is very high."

Ding Chunqiu nodded, this should not be a coincidence.

Especially people who buy silk scarves are wearing hats and masks, obviously don't want to be seen by others, very suspicious.

Luo Bixin and Ding Chunqiu looked at each other, a bold idea almost blurted out at the same time.

"Serial Killer"

Ding Chunqiu turned his head and continued to ask: "Male and female?"

Jiang Xiaobai: "Male, the voice is about thirty years old."

Everyone subconsciously looked at Fang Ze, waiting for his deduction.

Fang Ze glanced at everyone and said, "You think it's a serial killing."

Luo Bixin said: "The same silk scarf should not be a coincidence, it is very in line with the crime habits of serial murderers."

Ding Chunqiu on the side also nodded in agreement.

Hearing this, Fang Ze touched his forehead and said, "You mean to say that the murderer is going to kill five people, and Li Ruicheng is just the first one?"

"This is looking forward to continuing to die."

Ding Chunqiu said: "Fang team, there is indeed such a possibility."

Fang Ze glanced at him and said, "Then what do you want to do to check the whereabouts of the silk scarf, or check the people on the surveillance camera."

Ding Chunqiu thought for a while, and said: "I think we can suspend the investigation of Li Ruicheng's death first, the murderer may not know the deceased."

"Random Killing"

"Ok."

Ding Chunqiu nodded.

"How about concentrated sulfuric acid"

Ding Chunqiu said: "Perhaps it is to cover up clues, such as fingerprints."

Fang Ze was silent.

It is indeed a very bold idea. With just five silk scarves, the possibility of a serial murder case can be deduced, and the direction is not a problem.

If there is a second deceased and a second silk scarf, then this possibility can basically be confirmed.

But Fang Ze didn't agree in his heart.

The first is the murderer's method of killing, which can be said to be flawless.

Speaking of arrogance, if he wasn't here, it would be impossible to find out the real cause of death of the deceased.

The purpose of the murderer is to cover up the truth.

Then, if it is a serial murder case, this kind of cover-up becomes because it is impossible for five people in a row to die of cardiac arrest inexplicably, adding a very suspicious red silk scarf.

Doesn't this tell the police clearly: I killed it? What's the point? The second is the identity of the deceased.

According to Li Ruisi, his elder brother has practiced swimming, fighting, fencing and other sports since he was a child, and it is difficult for ordinary people to get close.

If a serial killer chooses a target, would he choose such a person? No matter how you look at it, it's Cen Xue who is next to Li Ruicheng, so it's easier to kill.

So Fang Ze didn't think it was

A serial murder case.

Although he can't explain the red silk scarf for the time being.

After expressing their own judgment, Ding Chunqiu and others thought about it and felt that it was indeed very reasonable, so they stopped insisting.

Just don't make a second death.

On the other side, Li Ruisi breathed a sigh of relief.

He was really afraid that the police would suspend the investigation of this case.

"Fang team, what to do next"

Ding Chunqiu asked.

Fang Ze said without hesitation: "Check the fingerprints and other traces on the silk scarf, as long as it is left by someone, don't let it go, including "OK."

Ding Chunqiu nodded.

Since it was left by the murderer, if we can find clues, maybe we can directly determine the identity of the murderer.

"Pump."

"Squad."

Pan Pu stepped forward.

Fang Ze said: "Go and find Li Ruicheng's personal doctor, and have a routine questioning."

"it is good."

Pan Pu nodded, and then left quickly.

Ding Chunqiu said: "Team Fang, Li Ruicheng's personal doctor is You Yinghao, a doctor of medicine who returned from studying abroad, he was recruited by Li Ruicheng from a first-class hospital with a high salary."

"We have investigated in detail and he has a very good alibi."

Fang Ze said: "I'm not doubting him, I'm just asking about other things."

"The murderer can achieve cardiac arrest without any trace of the deceased. He should not be an unknown person. The possibility of self-taught is very low."

"At the very least, you must have a good academic background and rich professional experience. You may be a doctor or a chemical expert. Let's ask first."

Ding Chunqiu nodded to express his understanding.

At this time, Li Ruisi's phone rang.

After glancing at the caller ID, Li Ruisi's expression changed, and he bid farewell to everyone and left.

Fang Ze and the others didn't pay much attention.

Such a big event happened to the Li family, it is estimated that Li Ruisi's phone calls will be blown up in the near future

Two o'clock in the afternoon: 2:.

Fang Ze met Li Ruicheng's personal doctor You Yinghao.

I didn't ask many questions, the key point was whether Li Ruicheng had contact with other high-end doctors or experts.

The answer is yes, but they are all casual acquaintances or business cooperation.

As for contradictions, no.

According to You Yinghao, Li Ruicheng is a very kind person, he respects technology professionals, he is also good to his friends, and has a good reputation.

So those people will not do anything outrageous towards Li Ruicheng.

It's four o'clock in the afternoon. 4.

Fang Ze and Luo Bixin sat on a bench by the side of the road, discussing the details of the case.

The initial investigation has reached this point, and there is not much to gain, so now there is only one direction left: to start with Cen Xue.

It's not suspicion, but the expectation that the other party can give more useful clues.

Li Ruicheng must have seen someone within 24 hours before his death.

So who is this person?

After chatting for a while, Luo Bixin said: "Cen Xue has been hit too hard, and she is still recovering. If she doesn't wait for her to speak slowly, her thinking will be clearer, and she may be able to remember the details she overlooked. .”

Fang Ze nodded: "Alright."

At this moment, Fang Ze's phone rang.

It was Li Ruisi calling.

Pressing the answer button casually, Fang Ze said, "Hey Rui Si, what's the matter?"

There was silence on the phone for a while, and said, "Old Fang, my father wants to see you."

"Ok"

Chapter 97 Can break [fifth update]

After hanging up the phone, Fang Ze turned to look at Luo Bixin next to him, with doubts on his face.

"What's wrong"

Luo Bixin asked.

Fang Ze shook his head: "I don't know, Li Ruisi said his father wanted to see me."

"Li Ruisi's Father"

Luo Bixin was stunned, and guessed: "You are both Li Ruisi's friend and the captain of the criminal police. The Li family has such a big incident, so you probably came to urge you to solve the case."

Hearing this, Fang Ze nodded and said, "Maybe."

"The other party is the father of the deceased, and also Li Ruisi's father. There is no reason not to see him. Go and see."

"Ok."

The two got up and walked towards Li Ruisi's residence.

Ten minutes later.

Originally, only Li Ruisi and Su Yao lived in the small building by the lake, but now it is full of bodyguards in black! Several luxury cars are parked by the side of the road, oppressing the passing pedestrians and tourists with their invisible momentum.

No one dared to approach, judging by the posture, Tian Lai Manor should have a great person coming.

As soon as Fang Ze and Luo Bixin approached, someone stopped them.

"I'm Fang Ze."

Fang Ze opened his mouth.
