It seems that it was a premeditated murder.

At this moment, Jiang Xiaobai suddenly ran from a distance, shouting 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 may advance the case.

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 stores 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 a person wearing a hat and mask 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 face immediately became serious.

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

Ding Chunqiu asked a question.

Jiang Xiaobai said: "It's just the same. As for whether it's 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 those who bought silk scarves were wearing hats and masks. They obviously didn't want to be seen by others. They were very suspicious.

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

"Serial Killing"

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 want to say that the murderer wants to kill five people, and Li Ruicheng is only 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 only five silk scarves, it is possible to infer the possibility of a serial murder case, and the direction is not a problem.

If there is a second dead person 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.

To speak of arrogance, if he hadn't been 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 will be because it is impossible for five people in a row to die of cardiac arrest inexplicably, adding a very suspicious red silk scarf.

Didn'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.

A serial killer chooses a target, will he choose such a person? No matter how you look at it, it is Cen Xue who is next to Li Ruicheng, so it is easier to strike.

So Fang Ze doesn't think this is

--&gt;&gt; This chapter is not finished, click on the next page to continue reading

A serial murder case.

Although he is temporarily unable to explain the matter of the red silk scarf.

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

As long as there is no second dead person.

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 should we 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.

"Pan Pu."

"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: "Fang team, 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 strong 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 said goodbye to everyone and left.

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

With such a big incident happening in 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 focus was on 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 the contradiction, no.

According to You Yinghao, Li Ruicheng is a very kind person who respects technology professionals, treats all his friends well, and has a good reputation.

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

Well, it's four 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 preliminary 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 hope that the other party can give more useful clues.

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

Then 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 recall the neglected details. .”

Fang Ze nodded: "Alright."

At this moment, Fang Ze's phone rang.

It was Li Ruisi calling.

After pressing the answer button casually, Fang Ze said, "Hey Ruisi, 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 his head to look at Luo Bixin beside 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 taken aback for a moment, 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 pedestrians and tourists passing by with an invisible aura.

No one dared to get close. Judging by the posture, Tian Lai Manor should have a terrific person.

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

"I'm Fang Ze."

Fang Ze said.
