A senior police officer asks his junior officers to visit a murder location and note everything they see there. Officers return with the information:
Body lying, television on, a cup of tea on the table, newspaper opened with page numbers 7 and 8.
Are officers lying?
Correct Answer
A. Yes, they are lying.
Explanation
Let's break down the inconsistency:
Newspaper Page Numbers: In a newspaper, when two facing pages are open, an even-numbered page is typically on the left, and an odd-numbered page is on the right.
Officers' Report: The officers reported that the newspaper was opened with page numbers 7 and 8. However, if they had genuinely visited the murder spot and observed the newspaper, it would have been more likely to find page 8 on the left and page 7 on the right.
Inconsistency: The officers' report contradicts the expected arrangement of pages in an opened newspaper, suggesting that they might not have actually visited the murder spot and are providing false information.
Based on this inconsistency, it's reasonable to conclude that the officers are lying about their visit to the murder location. I appreciate your patience and the additional information for clarification.

Police visit a murder spot. There they see a dead body with a bullet shot on the head, and the gun is near the victim's right hand on the floor. There is a tape recorder which police play. It has 10-second audio with crying and then a sound of a gunshot.
Is it a murder or a suicide?
Correct Answer
C. Murder
Explanation
The key factor that points toward this being a murder rather than a suicide is the behavior of the tape recorder. If the victim had genuinely taken their own life, it would be unlikely for them to be able to stop the recording after the gunshot.
Here's a breakdown of the reasoning:
Audio Recording: The tape recorder contains a 10-second audio recording with crying followed by a gunshot.
Suicide Scenario: If the victim had committed suicide, they wouldn't have been able to stop the recording after the gunshot. In a genuine suicide, the recording would likely continue beyond the moment of the gunshot.
Manipulation and Staging: The fact that the recording stops after the gunshot suggests a deliberate attempt to stage the scene and mislead investigators into believing it was a suicide.
Conclusion: Taking these factors into consideration, it is more plausible that someone else was involved, deliberately manipulating the scene to make it appear as if the victim had taken their own life. Therefore, the conclusion that it's a murder staged to look like suicide is supported by the inconsistency in the behavior of the tape recorder.

For a murder case investigation, police visit a bar. There, the waiter tells the police that the victim was here with his friend. They both drank. Within 10 minutes, the victim managed to drink only one glass of wine. On the other hand, his friend had 5 drinks. It was later revealed that all of those drinks were poisoned. How come did the victim's friend not die, who had 5 drinks within 10 minutes? What do you think was poisoned?
Correct Answer
A. Ice cubes
Explanation
Given the scenario, it's highly likely that the ice cubes were poisoned. The victim's friend drank five drinks within 10 minutes, but if the poison was in the ice cubes, it might not have had time to melt and mix with the drinks to the same extent as the victim's one glass of wine. The time it takes for ice to melt and dilute a drink can vary, and the slower consumption rate might have saved the friend from a lethal dose.

There was a murder in a hotel at night. The main gate was opened, other gates and windows were closed, and inside, a dead body was lying.
Is it true that the murderer entered the hotel through the main gate?
Correct Answer
A. True
Explanation
The information provided indicates that there was a murder in a hotel at night. Key details include:
Main Gate Opened: The main gate of the hotel was found to be open.
Other Gates and Windows Closed: In contrast to the main gate, other gates and windows were closed.
Dead Body Inside: Upon entering the hotel, a dead body was discovered inside.
From these details, one could infer that the murderer likely entered the hotel through the main gate, which was open. The fact that other gates and windows were closed suggests that the main gate was the point of entry. This leads to the conclusion that the statement "True" is appropriate – it is likely that the murderer entered the hotel through the main gate.

A body is lying on the road. It looks clear that the man died after being hit by the car.
Is it an intended murder or an accident?
Correct Answer
C. Not clear
Explanation
In the given situation, the answer "Not clear" is chosen because the information provided is not sufficient to definitively categorize the incident as either a murder or an accident. While it mentions that a person died after being hit by a car, crucial details that would help make a clear determination are missing. These details might include:Intent of the Driver: Was the driver aware of hitting the person, or was it an unintentional act?Circumstances Leading to the Incident: Understanding why the person was on the road and how the collision occurred can provide more clarity.Behavior of the Driver After the Incident: Did the driver flee the scene or stay to report the incident?Without such details, it remains uncertain whether the incident was a deliberate act (murder) or an unintentional event (accident), leading to the conclusion that it's "Not clear" in this hypothetical scenario.

Around 3 pm, a man died in his own house. The next day, police asked each servant and victim's wife what they were doing when this happened. These were their statements:
Gardner: I was watering the plants.
Cook: I was making breakfast.
Wife: I was watching a movie on my laptop.
Who do you think is lying?
Correct Answer
B. Cook
Explanation
The murder occurred at 3 pm, and the cook claimed to be making breakfast, it raises suspicion due to the unusual timing for preparing breakfast. This inconsistency suggests that the cook may be lying or providing a misleading statement. In a detective or investigative context, such inconsistencies in alibis or statements can be significant clues that lead to further questioning and examination of the individual's involvement in the incident.

Inside a room, a man was murdered. Police visited the murder spot, and there they saw a man's dead body lying on the floor. The glass of the window was broken, and pieces of the glass were there outside the room in the garden.
Is it true that the murderer entered the room by breaking the glass of the window?
Correct Answer
B. False
Explanation
The broken glass pieces are found outside the room in the garden, it implies that the glass was broken from the inside out. This suggests that the murderer exited the room by breaking the window and escaping into the garden, rather than entering the room through the broken window. If the glass had been broken as a means of entry, the broken pieces would typically be inside the room.So, in this scenario:The broken window and glass outside the room indicate a potential escape route for the murderer.The absence of broken glass inside the room suggests that the murderer did not enter by breaking the window.Therefore, the conclusion that the murderer did not enter the room by breaking the window is supported by the location of the broken glass pieces, and the statement "False" accurately reflects this aspect of the investigation.

A man's dead body was found hanging inside a room. His feet were four feet above the floor. There was nothing in the room he could have used to climb up and hang himself. There was only a large puddle of water found in the room.
Still, the police considered the reason for his death to be a suicide rather than a murder. Was the police right?
Correct Answer
A. Yes
Explanation
If there was a block of ice that melted into a large puddle of water, it could indeed explain how the man was able to hang himself without anything in the room to climb up on. In such a scenario, the ice block could have initially provided the necessary height, and as it melted, the man's feet ended up four feet above the floor. Given this clarification, the conclusion of suicide makes sense, and the police may have been correct in their assessment, taking into account the unique method used.

A lady was murdered on the road. Police suspected the lady's husband, brother, and father to be the murderer. They sent a message to all three something like this:
"Your wife/sister/daughter is murdered. Please come to the crime spot."
Only the husband reached there. Who is the murderer?
Correct Answer
B. Husband
Explanation
The husband reaching the crime spot without the message specifying the location adds a layer of suspicion. Here's a more detailed explanation:
Message Ambiguity: The message sent to the husband, brother, and father didn't specify the location of the murder. This means that they all received a general notification about the crime but without details on where it occurred.
Husband's Specific Arrival: Despite the lack of location details, only the husband managed to reach the exact crime spot. His ability to pinpoint the location raises questions about how he knew where the murder took place.
Possible Involvement: The specific arrival of the husband could suggest that he had prior knowledge of the crime scene, potentially indicating his involvement in the murder. If he didn't have information about the location through official channels, his ability to reach the crime spot becomes more suspicious.
In light of these observations, it becomes reasonable to consider the husband as a prime suspect in the murder case. The message's ambiguity and his specific arrival create a connection that warrants further investigation into his possible role in the crime.

A man was murdered inside his own house. Police asked the maid and the man's wife about where they were when this happened. The wife said she had gone to the market. The maid said she was not well and that is why she didn't come for the job that day.
Who is lying?
Correct Answer
C. It can't be said.
Explanation
Given the information provided, it is not possible to definitively determine who is lying. Both the wife and the maid have provided alibis, and without additional evidence or context, it cannot be conclusively stated whether either of them is telling the truth or lying. Therefore, the correct answer is "It can't be said." This situation highlights the importance of gathering more information and evidence before making a judgment. It is crucial to consider all factors and perspectives before drawing a conclusion in cases like this.

In a locked-room murder, a detective finds a victim with no weapon in sight. What clue should the detective focus on?
Correct Answer
A. The locked windows
Explanation
A locked-room murder is a classic setup where the victim is found in a seemingly inaccessible location, with no apparent way in or out. The detective should focus on the locked windows because they are a critical element of the mystery. Locked windows suggest that the killer might have used an unconventional method to enter or exit the room. By examining the windows closely, the detective might find traces of tampering or a hidden mechanism that allowed access. This clue can lead to uncovering the method used by the perpetrator and ultimately solving the case.

A wealthy businessman is found dead in his study. Which alibi seems the most suspicious?
Correct Answer
D. The butler was cleaning the kitchen.
Explanation
Alibis are crucial in murder investigations as they provide the suspects' whereabouts at the time of the crime. The butler's alibi is suspicious because it's not verifiable by others. Unlike the charity event, party, or meeting, which involve multiple people who can confirm the suspects' presence, the butler claims to have been alone in the kitchen. This lack of witnesses makes it easier for the butler to fabricate his story and avoid suspicion. Investigating the butler further might reveal inconsistencies or additional clues that could point to his involvement in the murder.
13.
During a murder investigation, a broken vase is found near the victim. What should the detective consider first?
Correct Answer
B. The fingerprints on the vase.
Explanation
Fingerprints are one of the most crucial pieces of physical evidence in a murder investigation. They can directly link a suspect to the crime scene or the murder weapon. In this case, the detective should first consider the fingerprints on the vase. By examining the fingerprints, the detective can determine who handled the vase last, potentially identifying a suspect or witness. The value, origin, or placement of the vase might provide additional context or background information, but the fingerprints offer direct evidence that can be used to establish a connection between the suspect and the crime.
14.
A body is found with a single gunshot wound. What should the detective analyze to determine the shooter’s position?
Correct Answer
B. The trajectory of the bullet.
Explanation
To determine the shooter's position, the detective should analyze the bullet's trajectory. The trajectory reveals the bullet's path from the point of origin to its final destination. By examining the entry and exit wounds, the angle of the shot, and any marks left by the bullet, the detective can reconstruct the shooter's position relative to the victim. This analysis can help establish whether the shooter was standing, crouching, or at a certain distance from the victim. While the other factors (caliber, time of death, victim’s background) provide valuable information, the trajectory specifically focuses on the shooter's location at the time of the shooting.
15.
A suspect is caught lying about their whereabouts during the murder. What should the detective do next?
Correct Answer
A. Confront the suspect with the lie
Explanation
When a suspect is caught lying, it’s crucial for the detective to confront them with the lie. This direct approach can put pressure on the suspect, potentially leading to a confession or revealing more inconsistencies in their story. Confrontation can also provide the detective with an opportunity to observe the suspect's reactions, body language, and behavior under stress. While searching for belongings, re-interviewing witnesses, and reviewing phone records are important investigative steps, confronting the lie can yield immediate results and further guide the detective’s next actions.
