1 minute to solve the case

Chapter 44
The Mystery of Bullet Scars
Late at night, the patrolling police found a car parked in the middle of the road, so they went up to check and found that there was only one dead man in the car. The man was shot in the left chest, and he was still holding a gun tightly in his right hand. .

According to the investigation, the deceased was a triad figure.There are two bullet holes on the front windshield of the car. The bullet hole on the right was shot by the murderer from outside the car; the bullet hole on the left was shot by the deceased from inside the car.

According to the police's estimation, this is a vendetta caused by the contradiction between the underworld.Sure enough, a few days later, the police arrested a member of another underworld organization. He himself admitted that he shot and killed the man, but he said this to the police handling the case:
"I was acting in self-defense! I was walking down the road and he shot me from the car, so I had to fight back, so I shot him."

Do you believe what he said?

can not believe.The reason is that the bullet marks fired by the deceased stopped at the glass bullet marks fired by the man behind, and the bullets fired by the deceased also fell in front of the car.

invisible weapon
The general manager of a computer company who was taking a nap in the lounge on the second floor was killed by the murderer who sneaked into the room, and his throat was cut by something sharp.

When the murderer was about to escape, he was caught by security.

To the surprise of the police, no murder weapon could be found on the murderer, and nothing similar to a knife could be found in the lounge.

Someone speculated that the murder weapon might have been thrown downstairs by the murderer.But after investigation, it was learned that several female employees had been sitting under the window, and they also confirmed that the window had been closed.

So, what weapon did the murderer use to commit the crime?Where is the murder weapon?

The murder weapon was shards of glass.

After the murderer cut the general manager's throat, he wiped off the blood and sank the glass shards into the goldfish bowl.Transparent glass is not easy to be found in water.

Incredible tire tracks
At about 11:[-] p.m. on Saturday night, a confidential document was stolen from a security room on the outskirts of City Z.The criminal went there by car, and there were very clear tire marks in the yard at the scene. The investigators used plaster to remove the tire marks.

The car was found after further investigation.It has been verified that the tires of this car are exactly the same as the tire marks on the scene.So I found the owner of the car to investigate.

"Nothing. I've been at home talking to friends on Saturday night and the car has been parked in a paid car park nearby."

The owner of the car has a very reliable alibi.

The public security personnel called the administrator of the parking lot, and the administrator confirmed that the car had been parked in the parking lot all night.He also said: "Although I didn't go out of the house all night, I sat in front of the window and carefully watched every car that came in and out. His car looks very unique, so I can guarantee that the car has never been parked." field."

So, how did this car with an alibi leave its wheel marks at the scene of the crime?
The real stealer also parked his car in the paid parking lot. He swapped the wheels of his own car with the wheel of the car suspected by the public security officers, and then drove to the yard of the secret room to commit crimes, deliberately leaving tire marks on other people's cars. In order to confuse the police officers.You know, it doesn't take much time for a skilled driver to change 4 wheels.

weirdo from hawaii
Zhizhi stood at the immigration gate of the international airport, his eyes were as big as copper bells.

According to intelligence, Maugham, who is engaged in international drug trafficking activities in Hawaii, is about to enter the country.

Maugham is very good at makeup. When he was in Hawaii, he had a big beard, and even acquaintances couldn't recognize him like that.

Zhizhi took Maugham's photo and prepared to arrest him.

There were quite a lot of people entering the country, but Maugham was not found.

In the end, Zhizhi discovered that there were 3 people who were particularly suspicious.

One of them had a piece of tape on his chin, a Japanese mustache, and sunglasses; another wore a floral Hawaiian shirt;

Akechi tilted his head, thought for a while, then approached one of them with a smile.

"Maugham, I've been waiting for you here for a long time..."

Excuse me, which one is Maugham?
Maugham is the sharp-eyed gentleman. Because the sun in Hawaii is very strong, Maugham is very tanned, but his shaved chin has not been exposed to the sun, so it is whiter.Maugham didn't notice this, and Zhizhi saw it through at a glance.

missing bullet

At a beach in a health resort, a man wearing swimming trunks was shot to death on the beach.There were two bullets in his sun-tanned abdomen.Died about six or seven hours before discovery.

According to the wound, both bullets should remain in the body, but the forensic doctor did not find the bullet after autopsy.

So, where did the two bullets go?

Two bullets dissolved in the dead man's body, and it was a warhead made of hard rock salt.This bullet will dissolve over time in the human body.

Did he fall to his death?

"When my uncle was painting the exterior wall, he accidentally fell off the ladder and died." A's nephew B told the police.

"I think my uncle must have stood on a high place and wanted to move the ladder to the side, but he accidentally fell down." B pointed to the very obvious traces of the ladder feet on the ground.

"No! This is not true." The policeman who had carefully inspected the scene said.

Can you tell why?

The position of the corpse was between the traces at the foot of the ladder and the wall. According to common sense, if it fell from the ladder, it should not be in this position, but outside the ladder.

characteristic criminal
The Agricultural Bank in the town was robbed at night.A masked robber broke into the house, tied the officer on duty to a post, gagged him, then used a key to open the vault and took all the cash.

In front of the vault, there are still the robber's footprints and half a candle.This is because it was too dark to turn the dial of the vault, so the robber lit a candle.

A few days later, the police found two suspects. Officer A didn’t ask them any questions, but invited them to dinner unexpectedly. But after eating a few mouthfuls, he suddenly pointed to one of the left-handed men and said: : "You are the robber who robbed the bank!"

Why did he make such a judgment?
The robber put the candle on the right side to unlock the vault door, so he must be left-handed.

boat that can't row

During World War II, Major Felfe and two of his soldiers encountered such a problem in Africa.

They were eager to cross a river more than ten meters wide, but the river was very gentle. There were many ferocious crocodiles in the river, and they could not swim across it. There was no bridge on the river.The only way is to use a small boat on the shore, but the boat has no oars, and the crocodile will bite off the hand if you paddle with your hands. There are piles of stones on the river beach nearby, and there are no sticks or the like. Don't dare to break a branch with a gun, that will attract the pursuers.

At last, however, Felfe and his men quickly crossed the creek by boat.What method did they use?

The stones on the river bank were loaded on the boat, and the three of them threw them back hard.When the stone is thrown hard, the foot will produce a reaction force, and the boat will slowly move forward.

Of course, this can only be done when the water flow is moderate.

If it is a torrent, not only will it be impossible to reach the opposite bank, but it will even be washed downstream by the torrent.

who first discovered the cannonball

In the weedy mountain forest, a small unit of our army is ambushing.Suddenly a shell hits...

After the battle, several recruits started talking.

A said: "I heard the sound of the shells flying, so I was the first to find the shells."

B raised an objection and said: "No! I discovered it first. I saw the shells fall on the rocks and explode with my own eyes."

C said not to be outdone: "I should be the first to find out. I saw the light flashing from the muzzle of the enemy's cannon."

May I ask who was the first to discover the shell among the three new fighters A, B, C, and others?

C, who saw the smoke from the muzzle, was the first, followed by B, and A, who heard the sound, was the last to find it.

Because the speed of light is as high as 30 kilometers per second, it can be seen almost at the same time as the gun is fired; it takes a little time for the shell to hit the target; when the sound is heard, the shell has already hit the past.

where does the water come from

In the scorching desert, an off-road vehicle was driving rapidly.In the car were several members of Garrison's death squad and a German general they captured.The German general knew a lot of military secrets, and Garrison and the others were eager to cross the desert and send him back to their intelligence department.

Due to the extremely hot weather, there was no drinking water in the car. The German general was injured. Coupled with the long-distance bumps, he passed out and murmured: "Water...water..."

"If we don't find any more water, he probably won't live long," Garrison said.

Several team members licked their chapped lips and said in unison: "Water? Where is there still water! There hasn't been a single drop of water since yesterday."

Garrison was also stumped. He pondered for a moment, then suddenly said: "No, we still have water! Of course it can't be said to be delicious, but it's still water." He stopped the car and fed some water to the German officer.

But there is not a drop of water in the desert.

Since the off-road vehicle can run in the desert, it means that there must be water in the water tank.Of course, the water in the water tank will not be very tasty, there is a lot of scale, and the taste is also bad, but it can save the life of the German general after all.

Wonderful Landing

Johnson and his two friends were tortured after being captured by pirates.After the pirates were drunk, for fun, they chained their hands to a small boat, and then pushed the boat into the sea.

They drifted for several days. Thanks to good luck, they finally drifted into a bay. However, because their hands were chained to the boat, it was inconvenient to move. Not deep, but there is a rapid current nearby that could easily throw the boat out to sea again.They tried their best and finally landed on land safely. May I ask, how did they land?You know, boats can't walk on land.

Managed to capsize the boat and the man went under the boat.

After the boat turns over, there will be air below, which can be used for people to breathe for a short time, and then several people work together to carry the boat to the island.

Notepad to solve the case

Little D is a well-known loafer. In order to pay off his gambling debts, he actually wanted to kill his aunt for money.

My aunt lives alone, and Xiao D called her in advance: "Auntie, I will visit you tonight, okay?"

"I'll be home after 8 o'clock tonight, but don't try to cheat me of money again." Aunt knew that when Xiao D came, he must be borrowing money or asking for money.

At around 8 o'clock in the evening, Xiao D brought a box of cakes to see his aunt.

"Hey, this is the first time that little D is so generous!" The aunt let down her vigilance, and she was poisoned to death just after taking a bite of the cake. It turned out that little D had coated the cake with potassium cyanide.

Little D swept away his aunt's money and was about to leave the scene in a hurry, when he suddenly found a line written in pencil on the notepad next to the phone: At 8:[-] p.m., nephew Little D made an appointment to visit.

Little D immediately tore off the paper, burned it, threw it into the toilet, flushed it with water, and then fled the scene.

The next day, Little D was arrested as soon as he woke up.The clue to solve the case is the notebook.How did you solve the case?
The words on the notepad were written in pencil, so there must be marks on the next page, and it is easy to know what was written on the torn page.

If it wasn't for Little D's case, no one else would tear up that piece of paper.

suicide or homicide
Policeman M is a big man, 186cm tall.

In a room with no tables and chairs and only a large cabinet, a man died suddenly. The height of the deceased was about 155 centimeters.

According to the forensic autopsy, the deceased drank strong poison, and the poison bottle was placed on the top of the cabinet.Policeman M stood on tiptoe, reached out and took the bottle down.

The bottle was indeed filled with that kind of potent poison, the bottle cap was opened, and there was only a small amount of liquid medicine left in it.

"This is by no means a suicide, but a homicide." Police officer M said confidently.

How did he deduce it?

Police M, who is 186 centimeters tall, had to stand on tiptoe to reach for the poison. The deceased, who was 155 centimeters tall, could not get it.Moreover, as long as he takes a little bit of this poison, he will die immediately. It is impossible for him to put the poison back after taking the poison, and there is nothing in the room to prop up.So the deceased was definitely not a suicide.

dark green sunglasses

C's car collided with B's car. B claimed that he was blind in his left eye due to the collision, and asked C to compensate him another 1 yuan. C was a little suspicious, so he asked police officer A to verify whether B's left eye was really blind, so police officer A asked B to get in his car.

Officer A held dark green sunglasses and broke the left lens while checking the engine.

"Although this pair of glasses is broken, you can still wear them. You can't see in your left eye. You should protect your right eye. The reflection on the road is so strong that it hurts your eyes." Police officer A said to B kindly.

On the way, there was some problem with the brakes of the car, and the road was a series of detours. Both of them were a little nervous.

"Help see if there are any traffic signs!" Officer A shouted.

"Yes! It's a stop sign with a black exclamation point on a red background!"

Officer A stopped the car immediately, smiled and said to B: "Mr. B, there is nothing wrong with your left eye. You want to blackmail us for 1 yuan, right?"

Police officer A has a purpose in asking B to wear sunglasses.Looking at red things through the dark green lens, the red will turn black, so it is impossible to distinguish the black logo on the red background, but B can actually see the logo, which shows that he is not blind in his left eye.

The Mystery of "Bottle Fruit"

After General A retired, because he had nothing to do, he often made some "bottle ships" for his subordinates to show that he cherished his time in the navy.The bottle boat is to stuff many parts of the sailboat through the thin bottle neck, and then assemble it in the bottle. This is a job that requires patience and time. Reynolds, General A's orderly, often stood by and watched him make a "bottle boat". One day, Reynolds suddenly said: "General, I will give you a gift in autumn." The general jokingly said, "Is that so? Why don't you give it to me now?" "No, it will take a long time to make this gift." "Is it as troublesome as a bottle ship?" The general wondered. "No, it doesn't bother you at all." Renault smiled slyly.

One day in October, Reynaud gave the gift to the general. "This is the 'bottle of fruit' I want to give you." The general couldn't close his mouth in surprise: Why is there a big, red and delicious apple in the thin glass bottle?And it looks like it was just taken off.

This apple is by no means fake. The question is how did Reynolds bottle it?

When the small apples just came out, they were covered with a bottle. Later, the apples grew up slowly in the bottle, and when they were ripe, they were picked and became "bottle fruit".

It's an inexpensive gift, but it takes months to grow.

smart scientist
In Greece 2500 years ago, there was a scientist named Thales, who was very good at mathematics, astronomy, philosophy and literature.

One day, King Amasis of Greece said to him: "Mr. Thales, I heard that you know everything, so please measure the height of the Great Pyramid of Egypt."

Pyramids are tombs built after the death of the kings of ancient Egypt, and the tallest pyramid is the tomb of King Khufu of ancient Egypt.

Measuring the Great Pyramid was a difficult problem under the conditions of the time.It is difficult to climb to the top of the pyramid, and besides, it is difficult to measure its height with a rope.This stumped Talles.But when he thought about it carefully, he finally came up with a way.

Tales came to the Great Pyramid and set up a stick in the sand.The sun's rays made the stick leave a shadow, and when the stick was as long as its shadow, Thales measured the height of the Great Pyramid.

Can you guess how Tales used to measure the height of the tower?
When the length of the stick and its shadow are equal, the height of the Great Pyramid must be the same as the length of its shadow. At this time, as long as the length of the shadow of the tower is measured, the height of the tower can be known.

flying weapon

One night, the manager who was working overtime in the office on the sixth floor was stabbed to death from behind by some sharp weapon.

The murder weapon was taken back by the murderer, but not left at the scene. The door was locked from the inside, and only the window behind the deceased was open.

In fact, the murderer killed the manager through the open window from the opposite building.

But the distance between the two buildings is 25 meters, even with a spear, it is impossible to kill people through the window.

So what kind of murder weapon did the murderer use, and how did he recover the murder weapon after killing someone?

The murder weapon used by the murderer was a bow and arrow.

He tied a long rope to the end of his bow and arrow and killed his victim through a window.After the arrow hits the victim's back, the rope is used to pull the arrow back.

driver robbery
One night, in a small town in Switzerland, a young woman went to the police station to report a crime.She said to the watchman:
"I was walking alone on the road, and a car came from behind. I leaned to the left of the road, and the car passed by on my right. At the moment it approached me, a hand suddenly stretched out from the car, and put my The purse was stolen. I hope you catch the robber as soon as possible."

"How many people are in the car?"

"Only the driver."

"Do you remember the license plate number?"

"I chased a few steps forward and saw that the license plate number was 9238."

The police immediately searched for a car with this number, but it happened that there were two cars with this number, one from country A and the other from country B.

Which car was the robber driving?

(Reminder: The traffic rules in country A stipulate that pedestrians and cars pass on the left side, while country B is on the right side.)
It was the driver from country B who robbed the girl.

The driver's seat of a country that stipulates right-hand traffic is on the left side of the car, while the driver's seat of a country that stipulates left-hand traffic should be on the right side of the car.Since there was only one robber, he robbed things while driving, and he snatched the bag from the right side of the girl, so the driver's seat must be on the left.
