Solved: The Detective Returns

"The murderer tied the deceased to a wooden cross and pierced the limbs of the deceased with four steel nails, while a video camera was placed about a meter opposite the deceased. "

Ma Guozhen said: "Then the killer used a long knife to easily cut the throat of the deceased, and he left a broken glass wine bottle on the ground. "

"The preliminary inference is that this wine bottle was broken by the murderer himself, and there are two possibilities for his motive for breaking the wine bottle, the first is to use the wine bottles that other people have drunk to confuse the eyes of our police detectives. "

"The other is that the bottle that he drank was broken, in order to leave a clue about his saliva, so as to provoke the police. "

"From the analysis of the current situation, the murderer's style of crime is fierce, the killing method is simple and neat, and the place of the murder is on the roof of the deceased's work building, which shows that the murderer is very bold, so it is inferred that the second possibility is relatively large. "

And the door lock on the rooftop at the time of the crime had an ordinary mechanical lock, the murderer did not violently pick the lock, and the murderer also took the initiative to lock the door lock after the crime, which proves that the murderer may have the key to the rooftop gate, or he himself is a master of lockpicking. "

"According to our investigation, the deceased Xu Huacai, who was only 39 years old in Chinese New Year's Eve, was a sales manager of Ping An Real Estate, divorced three years ago, and had a 19-year-old son studying in another province. "

"Xu Huacai has a fiery personality, only in the company, there are five people who have had conflicts with him, and we have investigated these five people separately, and we have not found anything abnormal. "

Ma Guozhen looked around at all the police officers in front of him and said, "The above is all the information we have so far, I want to hear your big guy's opinions and inferences." "

Hearing this, the police officers at the scene immediately discussed in a whisper.

One of the officers raised his hand and said, "From the clean wounds of the deceased's body, it can be inferred that the murderer should be a very powerful katana user." "

"The murderer used a knife drawing and slashing technique called 'Iai', and the knife technique was exquisite, hitting the throat and killing him with one sword. "

"My grandfather used to run a martial arts business, so I am also very familiar with these weapons, and there are not many people in our country who use this kind of katana, and even fewer who are proficient in it. "

The police officer said: "There are only a handful of people in our country who can use such a superb Juhe slashing technique. "

"I think we can start with this and conduct a broad investigation of all the people who are proficient in katana in our Z City. "

The police officer said: "The murderer has such a martial arts skill, his knife skills must be inherited, and it is impossible for him to be unknown, so the difficulty of our investigation will be greatly reduced." "

Hearing this, Ma Guozhen glanced at the police officer with an approving face.

The analysis is fine!

There are talents in my own team!

Although it is just an analysis of the direction of investigation, being able to behave like this in front of Lin Can is already a long face for himself!

Lin Can squinted his eyes and thought for a moment, and then slowly spoke: "You analyzed it very well. "

Hearing this, Ma Guozhen's face on the side showed a hint of joy.

Sure enough!

Even Lin Can personally praised it!

For a long time, the solving of cases in his team has basically relied on Lin Can's reasoning and analysis, Lin Can is nominally assisting in handling the case, but in fact it is their entire criminal police team that assists Lin Can in handling the case!

Now that there are finally police officers shining, Ma Guozhen can't help but feel a little relieved.

"But there was one thing you were negligent. "

Lin Can spoke again.

Hearing this, everyone's eyes were focused on Lin Can.

The joy on Ma Guozhen's face also immediately solidified.

Isn't it!

It's about to roll over so soon??

"Since the murderer dared to leave a fragment of a wine bottle with his own saliva at the scene of the crime, it means that he is definitely not a public figure. "

Lin Can continued to speak: "Otherwise, we will soon be able to compare the identity of the murderer through DNA testing, then his actions are tantamount to suicide." "

Hearing this, the police officers at the scene all nodded thoughtfully.

Lin Can is indeed right, if the murderer is a public figure and deliberately leaves his own evidence at the scene, it is no different from throwing himself into the net, only a fool would do it.

But Professor Lin ...... We don't seem to have determined the saliva content on the glass bottle, which is the murderer's. "

The police officer said a little unconvinced: "Captain Ma also said just now, we just speculate that the saliva on the glass shards is more likely to be the murderer." "

"Well said. "

Lin Can nodded calmly and said, "This is indeed a speculation, but there is one thing I want to ask you, why did the murderer put a camera in front of the deceased?"

"For the sake of video ......, of course

."

The officer said.

"Then why did he record it?".

Lin Can continued to ask.

"For ...... Keep a record of your killing so that you or others can enjoy ......."

The police officer was a little nervous by Lin Can's repeated questions, and a few drops of cold sweat slipped on his forehead.

"The location chosen by the murderer was on the roof of the building where the deceased worked, and every two days on this rooftop, maintenance workers would come up to do inspection work. "

Lin Can looked at the police officer in front of him, "Do you know why the murderer chose to commit the crime on such a conspicuous rooftop?"

"Because ......

".

The officer thought for a while, then shook his head and gave up, "I'm sorry, I don't know. "

"There is only one reason to choose a rooftop that is so conspicuous and that someone will definitely go up to inspect it to commit a crime. "

Lin Can said: "That is, the murderer himself wants the body to be found!".

Hearing this, the police officers at the scene were all stunned.

The inference that Lin Can just gave really surprised them, but combined with the previous findings, this analytical inference is indeed reasonable enough!

"You have to realize that we are now facing an extremely arrogant murderer!".

Lin Can's tone was cold, "Suppose you are such an arrogant murderer, choose a location that will definitely be discovered to commit a crime, and record the video of the crime, what will you do next?"

"I'll ...... I will ......".

Under the pressure of Lin Can's powerful aura, the police officer said in a trembling tone: "I will choose to release the video!".
