Tangjia Residence is located on the top floor of a villa area in a prime location in the city center...

The Tang family has strong financial strength and a prosperous population. Since three generations live together, when they commissioned the Wang family to build a house, they specially built this four-story villa. The location is independent and quiet, with the mountain on the back...

The scene of the murder was the study on the third floor of the Tang family's residence. Mr. Tang died in the room at that time...

Accompanied by plainclothes agents, Zhou Zixun and Chen Yuhan came to the door of the study.

"President!" Tang Duoqian was the first to come: "You are finally here! The real culprit must be severely punished..."

Mr. Zhou is here! Everyone in the Tang family stood up and said politely: "This distinguished guest is here. It's really disappointing to welcome him from afar!"

There have been murders...

Zhou Zixun looked displeased: "You people from the Tang family are still in the mood to engage in such vain politeness?"

That's... what Mr. Zhou taught you!

According to the descriptions of other people in the Tang family...

At that time, we heard the old man suddenly yelling downstairs, so we quickly came up to check...

"The door is locked from behind. No matter how we call the old man, there is no response!"

Later, in desperation...

Tang Duoqian responded: "A few of us immediately opened the door together, but the murderer had already broken the window and escaped..."

Just let the murderer run away?

Zhou Zixun frowned: "Then you didn't chase him? Could it be that...you didn't see the murderer?"

President, don't get excited...

Tang Duoqian said carefully: "When we hit the door, we heard the sound of the window glass breaking. So we opened the door, and the broken glass was still bouncing on the ground. At that moment, we immediately went to the window to check, but... outside

No one was seen at all!”

impossible...

Zhou Zixun reasoned based on common sense: "No matter how big this study is, it is nothing more than the master bedroom of an ordinary person. The moment you open the door and run to the window, it only takes two seconds..."

This is the third floor!

Zhou Zixun emphasized quickly: "Let's not talk about the surrounding area of ​​this villa, which is independent and quiet. Within 500 meters, there is not even a place to cover the body..."

Two seconds?

Zhou Zixun didn't believe it: "The prisoner can jump from the third floor in two seconds and disappear?"

Yes! Tang Duoqian confirmed: "We were at the window and we really didn't see anyone!"

Are you kidding me?

Zhou Zixun asked: "The third floor here is about twelve meters high. Assume that an adult weighs 50kg, g=10, and has an initial velocity when jumping down, but the initial velocity is unknown. Find the time from jumping to the ground. Do you know

How many seconds does it take?”

President... Tang Duoqian looked embarrassed: "You know, I'm not very good at studying!"

Is your study just not very good? Then let me tell you...

Zhou Zixun answered accurately: "It takes about 2.4 seconds for the murderer to fall to the ground, and what about you? It took about two seconds, but you didn't see anything at the window?"

Zhou Zixun's statement is not without basis, and it is impossible for a grandmaster to change the laws of physics...

Since the glass was still bouncing when he broke into the door, it means that the murderer happened to break the window and escape, landed on the ground in two seconds, and disappeared 500 meters away? Even Chen Yuhan couldn't help but be surprised...

How is the scene? Zhou Zixun looked at the plainclothes detectives: "Have you checked the scene?"

"The Tang family members hurriedly called the police afterwards. Only when the district officers arrived did we know that a murder had occurred in the Tang family..."

These plainclothes agents were the informants who stayed around last night: "We informed you immediately, and in accordance with your instructions, we immediately sealed off the place and guarded the door, not letting anyone in, including us. Own!"

That means...the site hasn't been surveyed yet?

Zhou Zixun's face turned slightly green: "Arrange the investigators to investigate the scene first... and see if we can find any clues!"

"I'll do the autopsy..."

Chen Yuhan took over the forensic gloves and inspected Mr. Tang's body...

The deceased was wearing reading glasses. He was most likely looking at something important before he was killed!

People usually start to stiffen from 30 minutes to 2 hours after death. It is speculated that the time of death is still within half an hour...

There were no obvious wounds on his body... It seems that the murderer did not use a murder weapon!

After careful inspection, Chen Yuhan found that the body of the deceased was tight and there were reddish marks on the acupuncture points under the shoulders. It was suspected that he had been stabbed with finger force or a sharp object. Judging from the shape, it was more like being stabbed with a sword finger (that is, the index finger and middle finger) merge)...

The temples on both sides collapsed, and Chen Yuhan stroked the scars...

It's not like it was hit by a heavy object, nor does it look like a scar caused by a fist...

Chen Yuhan guessed: "At that time, the murderer should have hit the deceased with his fingers from the front. When the deceased was bowing and protecting his shoulders with his hands, the murderer slapped his temples directly with both hands..."

The whole process should be very fast! Judging from the strength...

Chen Yuhan was convinced: "This was committed by a master. His strength should be at the middle stage of internal strength. But it's very strange..."

What happened? Zhou Zixun was confused!

because...

What surprised Chen Yuhan was: "A killer with middle-level internal strength, facing an old boy like Mr. Tang, could simply raise his hand to kill him! But the killer used two moves... and when he hit Mr. Tang with his finger power, He should have screamed out in pain subconsciously! The screams heard by the rest of the Tang family were caused by this!"

He can obviously win with one move and then leave quietly! Why should he cause the deceased to scream? Isn't he afraid of being witnessed by others?

Is this strange? Zhou Zixun speculated: "Could it be that the murderer suddenly had the intention to kill? Or maybe he didn't think so much under the circumstances?"

It shouldn't be possible! Chen Yuhan determined: "This is a senior warrior who knows the acupuncture points very accurately...very professional!"

Next, after a preliminary inspection, the detectives watched and recorded everything!

Chen Yuhan stood up and took off his gloves: "Others will have to wait for forensic autopsy or further testing with instruments."

But if you want to find more clues... I'm afraid it will be difficult!

How was the scene?

No suspicious findings have been found yet...

However! The examiner suddenly shouted: "Sir, can you take a look at this first?"

Zhou Zixun hurried over and followed the place pointed by the examiner... on the desk?

There is a torn and long piece of paper, pressed under the inkstone...

Judging from the paper, it looks like a student's lined math notebook...

However, judging from the paper and the ink on it, it must have been written a long time ago!

This thing...

Zhou Zixun judged: "It seems that Mr. Tang was wearing glasses at that time, using an inkstone as a paperweight, pressing the top of the ruled notebook to read the contents of the paper..."

"After the murderer took the opportunity to commit the crime, he wanted to retrieve this piece of evidence and escape. The knock on the door frightened him, so he didn't pay attention. In his panic, he tore the lined paper! It happened to leave the complete row on the paper.

..”

Judging from the fragments left behind, horizontally it reads...

Ten, one, two, three, four, five, six, seven, eight, ninety, Mojing people

There are a total of fourteen words on it!

What does it mean? Zhou Zixun's eyebrows were deep: "It seems... on the original paper, it sounds like there are fourteen lines written vertically. Here is just the first word at the beginning of each line. Based on these, it is difficult to guess the content.

..”

Thus!

Zhou Zixun's face turned slightly green: "Can we only rely on fingerprint collection at the scene for clues?"

wrong!

Zhou Zixun suddenly reacted: "Even if the killer breaks the window and escapes, it's just a bizarre escape! Then how did he get in?"
Chapter completed!
