The technicians at the Criminal University of Baocheng County believed that the ground there was relatively high, resulting in a series of dot-like blanks. However, Li Tianle used precise calculations in his own brain to conclude that there was an object blocking the blood in the blank space.
It's caused by flowing.
In addition, he also came to a very precise conclusion: the dot-like blank areas that were not stained with blood were caused by a string of highly stretchable bracelets.
So, does this bracelet belong to the murderer or the old man who was murdered? Li Tianle believes that it is much more likely to be the murderer. Because if the bracelet belongs to the old man, it makes no sense logically. The murderer was holding a murder weapon at the time and it was impossible to pull it
The old man should be killed as soon as possible to prevent his screams from alarming the neighbors.
In addition to these, Li Tianle also took some food, beef, etc. into the bowl and asked the technician to take it back for testing. This is also a problem that the Baocheng County police did not notice. In their opinion, the old man was killed and not poisoned.
There is no need to test food.
What's more, according to forensic reports, they did not detect any food residue in the stomach of the murdered old man. This means that the beef on the table has not been touched by the old man. Therefore, there is no need to inspect the beef on the table.
But Li Tianle ignored everyone's weird looks and continued to proceed at his own pace. When the funeral parlor's ice room checked the body of the murdered old man, his conclusion about the bracelet was confirmed. Because there was no trace of the bracelet on the fibers of the old man's clothing.
The murderer's fingerprints.
Li Tianle boldly inferred that the murderer was interested in the old man's antique calligraphy and painting. Maybe the two had not reached an agreement on the price or the sale, which made the murderer become malicious and brutally killed the old man and obtained the calligraphy and painting. But when he committed the murder, he
, but met with strong resistance from the old man.
During the fierce fight between the murderer and the old man, the bracelet on the murderer's wrist fell to the ground, but the murderer did not notice it at the time. It was only when he was leaving that he found the bracelet in a pool of blood. So he picked it up and took it away.
In addition, Li Tianle also had speculations about the business card of the sales company. He believed that just when the murderer finished the murder and took out the painting, the dying old man suddenly came back to his senses. He found a business card dropped by the murderer on the ground, so he used his last strength to kick the card away.
He went under the closet to leave clues for the police.
After the murderer took off the calligraphy and painting, he saw a bowl of freshly stewed beef on the table. He was so greedy that he ate a few pieces, and then quickly fled.
As for the murderer not leaving any footprints, fingerprints or saliva, that is because this person is a person who is very knowledgeable about counter-reconnaissance capabilities. Moreover, this person must have had shoe covers on his shoes before entering the room, and even wore them on his hands.
Comes with an anti-fingerprint cover.
It is actually quite understandable for Li Tianle to think so. With the improvement of people's material standards, it has become common for professional service personnel to use shoe covers and gloves when entering the house. And the murderer must have received training in this area. Under normal circumstances,
, his bag has all these tools.
Since his powers and IQ were upgraded to level 15, Li Tianle decided to use his own abilities to solve cases as much as possible. Because he felt that blindly relying on the genius button would be extremely detrimental to his long-term development. At the same time, he also believed in his own IQ.
When solving normal problems, there is no difficulty.
This is the real reason why Li Tianle did not use the genius button this time.
Except for Li Tianle's discovery of the bracelet imprint, the other circumstances are indeed similar to the conclusions reached by the people from Baocheng County Xingda.
When Li Tianle told everyone about his findings and inferences, the policemen at the Criminal Division of Baocheng County were in an uproar. They never expected that Li Tianle could deduce so many things from such tiny details. It was so monstrous.
Everyone looked at Li Tianle as if he were looking at a monster. When Director Liu told everyone that the unattractive young freak in front of them was the legendary detective Li Shi, everyone suddenly realized: Oh! No wonder he behaves so evil. It turns out that
It's Detective Li! The legend is indeed not groundless!
Since Baocheng County is a small county and does not have the qualifications to have a forensic identification center, the victim's body can only be borrowed and placed in a special ice charnel house in the funeral home, waiting for further identification and verification. Therefore, Li Tianle collected at the scene
After receiving the relevant information, they immediately rushed to the ice charnel house to check the body of the elderly victim.
Then he issued a series of instructions one after another. In addition to investigating the line of calligraphy and painting, there was also a team investigating the bracelet. In particular, he was the one who was looking for the owner of the business card at the scene of the accident, Mr. Chai, who actually led the team himself.
Taking that business card, Li Tianle visited Chai, who had returned to Baocheng County, and asked for a business card of the same style.
But Chai told Li Tianle that he seemed to have used this kind of business card before, but could not remember the details. But now, due to the difference in business scope and position, the style of the business card has long been changed. The clues to the business card seem to end here.
It was interrupted, but Li Tianle didn't think so, and he asked Chai to provide a place for printing business cards.
Maybe it was because he was in sales, but Chai was very willing to help. He personally accompanied Li Tianle to the printing company.
When he arrived at the printing club, Chai greeted the people inside in a familiar manner and explained his purpose.
The boss of the printing agency immediately cooperated with Li Tianle to find the archive of the business card in the computer file. Because the owner of the printing agency was a very good business person, and Chai was their regular customer, he left the archive in case of emergency.
This is a good habit developed by the printing agency owner over the years.
In the computer's files, it is easy to find the archive template file of this business card.
But the sharp-eyed Li Tianle immediately discovered the difference. Although the layout of the business card was the same, there was a misspelling of a letter in the foreign language on the address line at the bottom of the back of the business card. This subtle difference was slightly different from the template business card.
After Li Tianle pointed this out, the boss of the printing agency immediately patted his thigh and talked about the reason.
It turns out that the business card at the scene of the crime was printed by the printing company itself, not by the printing factory. Because the quantity Chai requested was relatively large, the printing company was afraid of typographical errors, so they printed a box themselves first.
Mainly to show the samples to Chai.
After the sample was produced, Chai happened to be out of town. He only looked at the fax and felt that it was not good so he did not continue to print it. Instead, he changed it to the same pattern but a different type of business card. This was also what Chai saw when he saw the fax provided by Li Tianle.
After receiving the business card, the impression was somewhat vague.
So how come such business cards, which are nearly printed in a box, end up outside?
The boss of the printing agency clarified everyone’s doubts. It turns out that this box of discarded business cards was placed on the computer table against the wall by someone from the printing agency, and accidentally fell into the gap between the computer desk and the wall. It was not printed until recently
The office repainted the interior walls and moved the computer desk before the wrong box of business cards reappeared.
Because it was well-sealed in plastic at the time, this box of business cards is still as new as ever after many days. The proprietress of the printing agency was reluctant to waste it, so she took it out and placed it in the reception area to make samples for customers.
When the boss of the printing company saw the fire, he "educated" the boss's wife severely. He said: It would be strange if such old-fashioned samples, which have been around for a long time, don't scare customers away.
The boss lady thought so! Don’t all those who do business pay attention to auspiciousness? Sometimes someone says to the boss of the printing company, boss, when will you close the door at night? The boss heard the fire, but he didn’t have anything to say to the customers, so he replied
:I don’t close the door at night, I just close it!
This also proves that the boss is a very "fastidious" person.
However, three business cards had been issued, and there was no going back. It was precisely because the boss of the printing agency was so worried about this that he still remembered the matter and quickly reported the details of these three people.
.
One of them is an academic staff member of the primary school next door, another is a small owner of a clothing store, and the third is a dealer who specializes in buying used items. But among the three, the owner of the printing club is the only one who has this idea.
A dealer who buys old things knows the person but doesn’t know his specific address?
When he heard the news, Li Tianle immediately realized that the third used goods dealer was most likely the murderer he was looking for. However, out of caution, he sent someone to verify the academic affairs clerk and the clothing store owner.
However, he himself asked the boss of the printing company to dictate the image of the second-hand dealer, and he himself drew a rough portrait of the second-hand dealer on the spot.
To the surprise of the printing club boss and the accompanying police officers, Li Tianle quickly drew a picture of a second-hand goods dealer under the dictation of the printing club boss. Moreover, the portrait of the character in the painting was exactly the same as the second-hand goods dealer in the printing club boss's impression.
, very expressive.
Li Tianle immediately printed out hundreds of color portraits of used goods dealers on the computer that printed social photos, and distributed them to the accompanying Baocheng County police officers so that they could quickly find the used goods dealer.
But when the police followed the colorful portrait and found the old-goods dealer's home, they were shocked to find that the family was holding a funeral. The person who died was the old-goods dealer who owned the colorful portrait.
After further investigation, the police officers found out that on the evening of the day the old man was killed, the used goods dealer asked his wife to drive to the hospital for treatment because of physical discomfort. Unexpectedly, a dog suddenly appeared on the road and the used goods dealer suddenly rushed out.
My wife instinctively turned the steering wheel.
Due to the high speed at that time, the car hit a road sign on the side of the road, breaking the road sign in half. The remaining broken road sign, after smashing the front windshield, reached into the cab and cut the passenger
The second-hand dealer in the driving position had most of his head cut off, and the second-hand dealer died suddenly on the spot.
In this way, any hope of interrogating the used goods dealer is dashed.
At this time, the professionals who tested the beef on the table of the murdered old man also came with the news. They detected that the beef stew of the murdered old man contained the ingredient of the tonic Laotushen.
