Xiao Lou's major is forensic medicine and he is best at toxicological identification. However, he has liked detective mystery novels and played escape room games since he was a child, so he is very familiar with the basic reasoning process.
When the police are dealing with a homicide case, if they can find the scene of the first crime, it will be of great help to the investigation of the case.
Xiao Lou judged that this was not the scene of the first crime, and the reason was actually very simple.
The heart is the blood supply center of the human body. It is like a powerful pump. Its regular beating every minute can send blood to all parts of the body. The fatal injury of the deceased was in the heart, and the position where the knife was inserted was close to the aorta. If the deceased was in
Someone stabbed him to death on the bed. After the aorta was cut, the blood spurted out and splashed onto the pillow, sheets and even the wall.
The surrounding area was clean, with no traces of blood splatter.
Her blood only soaked through the clothes on her chest. Judging from the amount of bleeding, it was about 10%, which was less than half of what a normal person would draw when they went to donate blood. She was obviously killed somewhere else, and when the blood flow was almost gone,
Then he was moved to the bed in the bedroom.
Killing, bleeding, and placing the deceased on a bed covered with rose petals. This murderer is obviously a psychopath!
Xiao Lou turned around and went to the kitchen, searching for other evidence and also wanting to confirm his inference.
There were some stains similar to blood stains on the dirty clothes left by the deceased in the bathroom, but from his professional point of view, they were not blood stains at all, but more like juice. The first thing he thought of was that it was closely related to juice.
kitchen.
Xiao Lou walked into the kitchen, and sure enough he saw a watermelon on the table. The watermelon was cut in half, and half should have been eaten. The remaining half was now rotten and smelly - there were blood-like stains on the hostess's clothes.
, it is watermelon juice.
There was a fruit knife inserted into the watermelon, and Xiao Lou gently pulled it out.
The sharp, slender fruit knife was exactly the same as the fatal injuries he found on the heroine when he examined the body just now.
This fruit knife is the murder weapon used to kill the heroine!
Xiao Lou's heart beat violently.
He began to search the kitchen carefully. If he guessed correctly, this was the real scene of the first crime!
The kitchen should have been cleaned and there were no obvious blood stains.
He squatted down and went to the corner to check the floor drain, and found some hair on the edge of the floor drain - short black hair about 3cm long, obviously belonging to a man. There were also a few drops of blood on the wall behind the water pipe that had not been cleaned up.
The discovery of the first crime scene and the murder weapon instantly increased the clue collection rate to 70%.
Xiao Lou turned over the trash can as usual. There were a lot of vegetable leaves, fruit peels, egg shells, and quick-frozen meat packaging bags in the kitchen trash can. It can be inferred that the heroine should have cooked a meal at home before she died.
And it was for more than two people. Vegetarian dishes plus meat, at least five dishes. She couldn't eat so much by herself.
Apart from this, no refrigerator or cabinets were found.
Xiao Lou turned around and went out. There was a large bouquet of roses on the dining table facing the kitchen. The glass vase in which the roses were placed was very delicate. The water inside was still very clear. The roses were blooming well, but some of the flowers had been picked off. It was possible that
That's where the rose petals in the bedroom come from.
Xiao Lou also turned over the trash can in the restaurant and placed it upside down on the ground. Apart from some peels, there was also a greeting card, a heart-shaped card commonly used in flower shops, with vigorous and powerful handwriting on it.
It read: "Happy birthday, my husband will always love you."
The clue collection rate has increased to 75%, and the roses and greeting cards are obviously helpful to the reasoning of the case.
Xiao Lou walked into the study room opposite the dining table.
There are many medical books on the bookcase occupying one wall, including several monographs on cardiac surgery.
Next to the bookcase is a very common desk with a desk lamp on it. There are three drawers on the right side of the desk, and a small cabinet with a door on the left. Xiao Lou opened the drawer and found his passport in the first drawer and medical practitioner qualification certificate, belonging to the male owner of the family. He finally learned the information about the male owner - Zhao Sen, born on October 26, 1988, Han nationality, is a surgeon.
In other drawers, there are lists of property fees, bank receipts and medical papers, which are not very helpful to the case.
Xiao Lou closed the drawer and opened the cabinet door in the lower left corner.
A black safe was found in the cabinet, with a combination lock and four rows of digital code disks. From top to bottom, they were 123,456,789,*0#. He had seen many such safes. After pressing the correct digital code, he pressed # Just press the key to unlock.
Numeric code...
The numbers involved in this case are currently only the birthdays of the male and female owners.
The best friend gave the heroine perfume and said happy birthday; in the greeting card from the restaurant, her husband gave her roses and also said happy birthday. Multiple clues mentioned "birthday", this date is definitely not simple.
The male host's birthday can be found on the doctor's qualification certificate, which is October 26, 1988. Xiao Lou remembers the hostess's birthday very clearly. On the greeting card written by his best friend, the final date of signature is: July 17.
The password box of the safe is four digits. He entered 1026, and it was prompted that the password was incorrect. Xiao Lou then entered the hostess's birthday, 0717, and pressed the # key.
A crisp sound of "pop" broke the tranquility of the murder scene, and the safe was indeed opened.
——The clue collection rate suddenly jumped to 90%!
At this time, there are 18 minutes left in the countdown.
The interior of the safe has an upper and lower structure. There is a folder on the upper floor. Xiao Lou took it out and quickly flipped through it, extracting key information at a glance.
There are two insurance contracts. In the first one, the insured's name is Zou Xiaomei and the beneficiary's name is Zhao Sen. The relationship between the two is husband and wife. The second one is the opposite, the insured is Zhao Sen and the beneficiary is Zou Xiaomei.
The couple bought commercial insurance for each other, including medical critical illness insurance and personal accident insurance. The annual payment amount is more than 10,000 yuan. If the insured person is hospitalized due to serious illness such as tumors, cardiovascular diseases, etc., the annual premium is less than 500,000 yuan. Hospitalization expenses can be fully reimbursed; if the insured dies unexpectedly, the beneficiary can directly receive compensation of up to 2 million yuan from the insurance company.
When Xiao Lou saw this insurance contract, he was frightened for a moment.
He also bought commercial medical insurance for his parents. It is normal for relatives to buy insurance for each other. However, cases of killing people to defraud insurance are not uncommon. He once saw the news that a son killed his mother just to defraud the insurance money. It was so heartbreaking. !
In this case, the relationship between husband and wife has broken down. Once Zou Xiaomei dies in an accident, Zhao Sen will receive up to 2 million yuan in compensation!
Xiao Lou felt a chill down his spine, put down the insurance contract and continued to dig through the safe on the lower floor.
There are several photo albums on the lower floor.
There are many photos of Zhao Sen in the photo album, from elementary school to junior high school, high school, and college graduation, recording his complete growth trajectory. He was probably congenital myopia and wore glasses when he was very young. From the photo album, this person
On the surface, Zhao Sen is a very gentle and easy-to-get-together person - because he is smiling in every photo.
In addition to personal photo albums, there are also several wedding photo albums. The couple seemed very loving when they first got married. The man hugged his wife in a very gentlemanly manner, while the woman leaned against his arms like a little bird, smiling.
sweet.
Scroll further...
Xiao Lou saw the photos of the wedding scene.
There is a group photo of four people. In addition to the groom and the bride, there are also the best man and the bridesmaid.
This group photo was obviously taken from the side, and none of the four people looked at the camera lens. In the photo, the bridegroom and the bride looked at each other and smiled, the bridesmaid looked at the best man affectionately, and the best man not far away stood.
The crowd held up goblets and toasted people, but their eyes were fixed on the bride.
Xiao Lou immediately cheered up.
——The fourth person related to the case appears!
This best man also appears in Zhao Sen's personal photo album. In Zhao Sen's graduation photo, there is a photo of two people holding their shoulders. They should be close friends. Zhao Sen will ask him to be the best man when he gets married.
Logically speaking, a friend's wife should not be bullied, and a man would generally avoid the wife of a good buddy, but the best man's direct gaze, as if staring at prey, is obviously not the attitude he should have towards his brother's wife.
Xiao Lou continued to look through the safe and found a document bag in a secret location on the bottom floor.
When he opened the document bag, he found a contract, which was an investigation agreement secretly signed by Zhao Sen and a private detective. The content of the investigation was the relationship between his cousin He Yongqiang, his wife Zou Xiaomei, and his wife's best friend Liu Yun. When Xiao Lou pulled out the contract
, and a large stack of photos also fell out.
He picked up the photos, and they were all snapshots of the three people going shopping and eating together. In some photos, Liu Yun and He Yongqiang were holding hands and acting intimately. In other photos, it was Zou Xiaomei and He Yongqiang holding hands and hugging - He Yongqiang.
The scumbag is clearly in two different situations. While he is in love with the young and beautiful Liu Yun, he is also seducing his cousin-in-law!
The last few photos are very large in scale, with Zou Xiaomei wearing thin silk pajamas and making out with He Yongqiang in the bedroom...
These photos at home were taken from a bird's-eye view, with time stamps in the upper right corner. Obviously, Zhao Sen had installed surveillance cameras at home at this time to monitor his wife's movements at any time. These photos are from
Screenshots from surveillance.
Xiao Lou: “…………”
What a bloody drama!
The one who cheated was not the male host Zhao Sen, but the hostess Zou Xiaomei who died on the bed!
If he had not opened the safe in the study, he might have misjudged that the male protagonist was cheating on his best friend, so the female protagonist angrily tore up the marriage certificate. Now it seems that it was the female protagonist who was cheating on her, and the person she cheated on was her husband's cousin.
My best friend’s boyfriend…
This reversal came unexpectedly.
Xiao Lou put down the photo in shock and quickly adjusted his mood. He looked at the prompt in the floating box. The clue collection rate was fixed at 90%, and the safe was a big clue accounting for 15%. From the clues in the safe, he knew
The names of everyone involved in this case - the deceased Zou Xiaomei, her husband Zhao Sen, her lover He Yongqiang, and her best friend Liu Yun.
There is a complicated relationship between these four people. He Yongqiang is Zhao Sen's cousin and Liu Yun's boyfriend. Zou Xiaomei cheated on him with He Yongqiang, which is equivalent to cuckolding her husband Zhao Sen and her best friend Liu Yun at the same time.
As victims, Zhao Sen and Liu Yun both had reasons to kill her. But who the specific murderer is needs further confirmation.
The clue collection rate is 90%, except for the last key clue that has not been found.
Xiao Lou turned around and came to the living room and searched carefully, but found nothing.
When he rummaged through the last children's room, he found a mobile phone and power bank next to the pillow in the children's room. The mobile phone had a pink case and should have belonged to the deceased Zou Xiaomei.
Such a crucial clue is actually in the farthest children's room, which most people would not search for first!
Xiao Lou's eyes lit up and he immediately picked up his phone.
He pressed the power button, and a line prompting "Please enter your password" popped up on the screen, and a numeric password disk appeared.
Xiao Lou subconsciously entered the heroine's birthday "0717". However, a warning popped up on the screen: "Password verification error. The phone will be automatically locked after 5 errors. The remaining times are 4."
He then entered the birthday of the male owner, 1026, and the prompt was: "Password verification is incorrect. The phone will be automatically locked after five errors. The remaining times are 3."
Not a birthday password? What is that?
The countdown in the floating box shows 15 minutes left.
Xiao Lou frowned and fell into deep thought.
He has searched all the bedrooms, bathrooms, study rooms, children's rooms, kitchens, and dining rooms. The heroine's birthday is July 17th, and the hero's birthday is October 26th. Other than that, there is nothing related to numbers.
clues.
If it were in reality, the deceased's mobile phone password could be set at will. If the police couldn't solve it, they would ask professional technicians to crack it. But now, he was alone in the secret room and found the mobile phone, but couldn't solve the password. He couldn't be blind.
Guess?
Xiao Lou picked up the phone and thought for a while, then turned and returned to the bedroom.
When the phone locks the screen and a prompt "Please enter your password" pops up, most people may be confused about what the password is and waste time looking around for password clues.
But Xiao Lou had searched the entire room as quickly as possible just now, and he was very confident that there was nothing he missed.
Since the password of the mobile phone is not the birthday, there are no other clues related to numbers in the whole house. Therefore, the prompt "Please enter the password" that pops up on the mobile phone may also be a "distraction".
——Who said you can only enter a password to unlock your phone?
Xiao Lou took the phone back to the master bedroom, walked to the rose bed, raised the deceased's right hand, and placed her right thumb on the fingerprint button of the phone.
The pink mobile phone and power bank left at home naturally belong to the hostess.
The hostess was lying on the bed. Although it was a corpse, her fingers were still there.
Wouldn't it be more convenient to unlock it with her fingerprint?
