After lunch, Wu Feng went directly to the Hancheng Police Station.

If the detective investigation case can be cooperated by official people, it will be much smoother.

The person who received Wu Feng was an old police officer in his fifties, named Jin Donghai, who looked unwilling to cooperate.

"It's been a year since Li Caihui's case, why are you detectives still endless?" Jin Donghai looked tired, and Wu Feng's arrival disturbed his nap.

"Is the case closed?" Wu Feng asked rhetorically in an unkind tone.

Different methods are used to deal with different people, Jin Donghai looks like the kind of mediocre policeman who lives in the police station and waits for retirement, if Wu Feng and Yan Yuese ask him to cooperate, Jin Donghai will put on a high-minded and ignorant look.

This kind of person has to go toe-to-toe with him and suppress him from the momentum, so that he will obediently cooperate.

"The case has not been closed, but our police have already concluded that Li Caihui was killed by him, but the murderer has not been found yet." Jin Donghai saw that Wu Feng's tone was not good, but his attitude was better.

A person like Jin Donghai has been in the police station for a long time, and he has already cultivated his eight-sided exquisite skills, and he will figure out the opponent's strength according to the opponent's attitude.

If the other party whispers, then there must be no background and relationship, and you don't have to be polite when you speak, you can handle it casually.

If the other party is very strong, it means that the other party has capital to rely on, and you have to deal with it well.

"Since the case is not closed, let's take out the detailed file of the case, and I will make a copy." Wu Feng said unceremoniously.

There is also case file information on the APP of the Detective Association, Wu Feng has read it many times, and he found that the information in it is not complete, and it may only be a part of the information uploaded.

Moreover, in the past year, the police should have obtained more clues, so Wu Feng's first stop was to go to the Hancheng Police Station to consult the detailed files.

"Don't be so troublesome, I have made a backup of the case file in a USB flash drive, just give it to you directly."

The more unkind the other party is, the better Kim Donghae's attitude becomes, and in the past year, dozens of waves of detectives have come to the detectives who received Li Caihui's bizarre death, and two photocopiers in the police station have been broken. Later, with experience, the police department directly made an electronic version of it, saving waste of time to copy.

"Then you're welcome." Wu Feng took the USB flash drive.

An hour later, Wu Feng arrived at the scene of Li Caihui's case.

Li Caihui's house is a large flat of nearly 300 square meters, the living room can be used as a basketball court, and there are floor-to-ceiling windows on three sides, and the scenery outside the window is unobstructed.

The life of a rich person is good, and the bathroom of this house is larger than Wu Feng's bedroom.

Wu Feng took out a pink notebook from his backpack, plugged it into a USB flash drive, and checked the photos of the crime scene, the notebook belonged to Tang Xiaowu, and was temporarily requisitioned by Wu Feng before leaving.

Originally, Wu Feng planned to take Tang Xiaowu and Zhang Dali out to practice, but Tang Xiaowu's foot injury was not healed, he was limping, Zhang Dali was still in the period of stress trauma after the killing, and the two had to stay in the Black Thorn Detective Agency.

In the photo, Li Caihui's hands are tied in front of her, a men's belt is tied around her neck, hanging from a clothes pole on the balcony, Li Caihui's feet are more than half a meter high from the ground, and there is nothing to step on under her feet.

Wu Feng found the clothes pole on the balcony according to the photo.

Judging by the situation at the scene, this was a typical homicide.

There are several reasons for this:

The deceased's hands were tied.

There was nothing to step on under the deceased, and the possibility of suicide could be preliminarily ruled out.

Wu Feng checked the hand crank of the clothes pole and found that it was an old-fashioned manual clothes pole, not an electric one.

This further excludes the possibility of suicide.

When Li Caihui couldn't hang herself, she went to shake the hand crank of the clothes pole by herself.

The autopsy report showed that the deceased had sleeping pills in his body and showed no signs of resistance before his death.

Wu Feng initially had a guess, and a picture was formed in his mind: after the murderer gave Li Caihui sleeping pills, he took advantage of Li Caihui's coma, tied Li Caihui's hands, put a men's belt around his neck, and hung it on the clothes pole on the balcony.

If this speculation is true, Lee Sung-dong and Han Jae-sung, who appeared at the scene of the crime, are both suspected of committing major crimes.

Obviously, Han Jae-sung, who appeared last and stayed in the room for 45 minutes, is more suspicious.

Because if Lee Chae-hui was killed by Lee Sung-dong, then Han Jae-sung probably wouldn't be alone in the room with a corpse for 45 minutes, unless he has a special fetish for corpses.

However, there is still a suspicion in the photo: the deceased had his hands tied in front of him.

It stands to reason that Li Caihui has already fallen into a coma because of taking sleeping pills, so there is no need to tie her hands anymore, which is a bit of a snake.

Wu Feng looked at the cable tie that tied Li Caihui's hands in the photo, and the cable tie seemed to say, "Do you see it?" This is a homicide, not a suicide. ”

Could it be that the dose of sleeping pills is not large enough, and the murderer is afraid that Li Caihui will wake up halfway, so he will do more.

This is only a suspicion, and more evidence is needed to confirm it.

Wu Feng continued to look at the photo, in which Li Caihui was wearing pajamas at home, her forearm was exposed, and there was a tattoo on her right forearm, which extended from the inside of her upper arm, looking like a snake.

It is normal for female artists to get tattoos, but it is rare to use snakes as tattoo patterns.

But this does not seem to have anything to do with the case.

Suddenly, Wu Feng discovered a detail: the curtains behind the clothes pole on the balcony were open, and one window was open.

Why are the curtains open? Isn't the murderer afraid of being seen by the people on the opposite floor when he kills?

And there is also a window open, the night of Li Caihui's murder was Christmas Eve, and the temperature at night has reached below freezing.

Why did you open the windows at that time?

Wu Feng looked up the police record of Li Caihui's case in the file, and it was Li Caihui's assistant who called the police, and on the morning of the second day after Christmas, Li Caihui had an advertising endorsement activity, and the assistant saw that Li Caihui had not shown up for a long time, and he couldn't get through on the phone, so he found Li Caihui's house and found Li Caihui's body hanging on the balcony.

From the analysis of the content on the photo, Li Caihui has a high possibility of homicide, and although the possibility of suicide is extremely small, it cannot be completely ruled out.

The reason why it is said that the possibility of suicide is extremely small is because Wu Feng can't find a way for Li Caihui to commit suicide for the time being, and it is impossible for her to hang herself on the clothes pole and then shake the handle of the clothes pole to lift herself up.

Unless Li Caihui was stepping on a half-meter-high ice cube under her feet at that time, which is a common technique used by Conan.

Ice cubes on the feet and skates that kill people are Conan's favorites.

However, judging from the photos, there were no traces of melted ice on the ground below the body at that time.

Next, Wu Feng looked at a few more photos, which showed that there were many men's clothes in one of Li Caihui's rooms.

In her own room, there are all kinds of women's clothing, most of which are uniforms, student uniforms, nurse uniforms, maid uniforms, professional clothes, camouflage uniforms......

This is most likely the hobby of Han Jae-sung, the prince of Tongtian Group.

But this hobby is too wide, and basically every profession is not missed.
