The autopsy report shows that the cause of Sun Biao's death was mainly that his throat was cut, and the knife in his temple must have been stabbed backwards, and whether Sun Biao was still alive at the time of the stabbing was too short to judge. Other physical indicators were normal, and other mortality factors such as poisoning and sudden illness were ruled out.

The results of the on-site investigation are as follows:

1. Sun Biao was holding a dagger in his hand, which was confirmed to be his own, and the blood occupied by the dagger was identified as Zhang Wanfa's. Judging from the adhesion of the blood stains on the dagger, it should be that the probability of stabbing is relatively large.

2. There are almost no traces of fighting in the room, indicating that the possibility of a sudden attack is relatively high, but Sun Biao's force value is also very high, and there are two possibilities for being killed so easily, one is that the opponent's force value is much higher than Sun Biao's, so that he has no power to fight back. The second is an accidental sneak attack, such as a sneak attack by a trusted person.

Of course, there is a more reasonable speculation, that is, Sun Biao was attacked and cut his throat as soon as he put on his shirt, because his shirt was a T-shirt with a pullover, and the murderer was likely to have his hand at the moment when he put the T-shirt off his head. Also, he only wore a jump of panties, and the pants were still on the couch next to him.

If this is the case, the murderer should have been very close to him at the time, because the opportunity was fleeting, so it is likely that he also knew someone. (Personal inference, for reference only)

3. The murderer went into the bathroom and washed his hands, and there were some bloodstains on the ground, which belonged to Sun Biao. But there were no fingerprints, the shower was on. The murder scene was moved in a small area, but no fingerprints were left.

"It was Zhang Wanfa who killed Sun Biao, what do you think?" Wang Zishan suddenly asked.

Shi Kun, who was sitting opposite, was stunned for a moment and asked, "What?

Wang Zishan's sudden question was a deliberate test of Shi Kun, she always felt that there was something wrong with this person, but she didn't know where the problem was.

Shi Kun was startled, he almost blurted out the other party's words just now, but fortunately he held on. In my heart, I paid more attention to this deputy director Wang Zishan.

"It's nothing, let's talk about you!What is your relationship with Wu Yuxi?" Wang Zishan continued to ask.

Shi Kun: "It's a doctor-patient relationship, of course, she's also my life-saver." ”

Wang Zishan: "What do you say?"

Shi Kun: "They said that I was seriously injured at that time, and if it weren't for them, I would have died." ”

Wang Zishan: "Is it an injury, not a disease?"

Shi Kun: "I don't know, I have amnesia." ”

Wang Zishan was stunned for a moment: "Amnesia? You just said they saved you, who else?"

Shi Kun: "I do have amnesia, I can't remember the past at all, they can testify, in addition to Wu Yuxi, there are also about Biqiong and Lin Yi." Yes, it was the three of them who operated on me. ”

Wang Zishan: "I will verify whether what you said is true, why did you accompany Wu Yuxi to Wanhualou? Do you know who she is going to meet and what she is going to do?"

Shi Kun: "Accompanying her can be regarded as repaying her kindness, no one accompanied her, so they found me." Said to go to meet someone and talk about something. ”

Wang Zishan: "Do you know about Wu Yuxi's drugged?"

"What? drugged, drugged by whom, how is she now?" Shi Kun said eagerly.

Wang Zishan stared at him for a long time before saying, "Just when you were holding her, she had already been drugged." ”

Shi Kun: "Ahhh ”

Wang Zishan: "As her bodyguard, why did you leave for so long?"

Shi Kun was slightly panicked and said: "What bodyguard? I'm not a bodyguard, I'm just going to accompany her as a friend, how did I know that it was so dangerous?"

"Answer me, why did you leave for so long?" Wang Zishan asked.

Shi Kun: "My stomach hurts, I went to the toilet!

"By the way, Zhang Wanfa's two subordinates can testify for me. Shi Kun added.

......

After verifying a few more questions, Wang Zishan did not get any unexpected clues, and Shi Kun's confession can be corresponded to the confessions of other people, without any suspicion. However, he was still determined to wait for the case to be over and to investigate Shi Kun in detail.

Back in the monitoring room, Lao He asked, "Did you find anything?"

"The more problematic people seem to be, the more problematic they tend to be, and they can't let go of any details. Wang Zishan thought for a while before saying.

Lao He smiled: "That's right. But I wondered in my heart, how could this Shi Kun offend Deputy Bureau Wang? It seems that he has been targeted! Why are other people not like this?

Wang Zishan actually doesn't have any evidence, and her approach is indeed a bit aimed at Shi Kun, maybe it's the reason why Shi Kun's identity is unknown, or maybe it's a woman's intuition!

Shi Kun didn't feel targeted, because he didn't know how the other suspects were interrogated, so he now exercised his body whenever he had time to lay the foundation for practicing "Xingyi Boxing" after going out, and he didn't have the consciousness of being a criminal suspect at all.

Shi Kun and Wu Yuxi are only indirect suspects, and if there is no new evidence pointing to them, they can be released soon.

Wang Zishan rubbed her brows and rested for five minutes, sorted out her thoughts, and the time had come to 1:15 in the morning, looking at Zhang Wanfa, the only one on the monitor who was still interrogating. Decided to go and take down this old fritter himself.

Zhang Wanfa sat there without saying a word, he was still a little flustered during the first interrogation, although he didn't say the point, he was more or less willing to answer questions, probably because he was a little drunk, but after this period of buffering, he calmed down.

As soon as the second interrogation began, he asked to see his lawyer, otherwise he would not confess. He didn't want to get by, he just wanted to stall for time and wait for someone outside to help him out. Because what happened in the Rose Pavilion was so weird that he couldn't tell it himself.

So the interrogators interrogated for a long time and found nothing. Just when he was wondering if he would make this old boy suffer a little, he received Wang Zishan's instructions, and she came to trial in person.

Wang Zishan replaced the interrogating police officer, and looked at Zhang Wanfa, who was silent, she didn't expect that Zhang Wanfa, who was still a little unbearable in front of her, seemed to be a different person at this time.

Wang Zishan smiled contemptuously and said, "Zhang Wanfa, don't you tell the truth? We already have enough evidence to prove that you are the murderer of Sun Biao." How about I give you a chance to get leniency? Do you want to take the initiative to confess?"

Zhang Wanfa was a little panicked, but he was still very calm, after all, the master of a big gang was not so easy to get mixed in, and the previous unbearable performance was mainly due to the scene that happened in the Rose Pavilion that left him a psychological shadow.

He glanced at Wang Zishan with a smile and said, "Now that you have the evidence, you won't be so troublesome." I really didn't kill anyone, how do you want me to explain?" Zhang Wanfa knew Wang Zishan, and he also knew that she was not an ordinary criminal policeman, so naturally he couldn't say a word like he did with an ordinary criminal policeman.

Wang Zishan said lightly: "Zhang Wanfa, you really don't shed tears when you don't see the coffin! Then I'll tell you how you killed people." If I'm done, there's no chance for you to confess. ”

Zhang Wanfa was still indifferent, but he was beating the drum in his heart.

Wang Zishan recounted: " At 8:32 last night, you entered the Rose Pavilion where Sun Biao was located, and saw Sun Biao getting dressed, because he was wearing a jumper, and when the clothes were put off his head, his eyes had a moment to adapt, and you saw the opportunity to cut off Sun Biao's neck with his dagger, Sun Biao did not die for a while, picked up his own dagger, and stabbed you, you alarmed Sun Biao's bodyguards outside in order not to make too much noise, so you fought to let yourself be stabbed in the arm, and stabbed Sun Biao in the temple, resulting in Sun Biao's complete death. ”

Speaking of this, Zhang Wanfa moved his body and rubbed his nose, looking a little uncomfortable.

Wang Zishan continued: "In order to erase the clues, you first go to the bathroom to wash your dagger and the blood stains on your body, just when you are about to erase other evidence in the room, your fight still alarmed Sun Biao's bodyguards, Sun Biao's bodyguard Li Bin came to check, you are afraid that the matter will be revealed and Sun Biao's two bodyguards will kill you in the Rose Pavilion desperately." So you hurriedly left the Rose Pavilion and ran away, and lied to Li Bin that Sun Biao was taking a bath, and asked them not to disturb. You left at less than 8:37, which means that it took you less than 5 minutes to kill Sun Biao in Sun Biao's room.

When you left, in order to prevent Li Bin from seeing the wound on your arm, you wrapped a white towel around your arm, but this became one of the evidences that Li Bin found Sun Biao's abnormality, causing you and your bodyguards to be chased by them before they ran far, so the five of you fought from the stairs on the second floor to the first floor, and were finally stopped by Wanhualou. Therefore, the knife wound on your arm was not left by you during the fight, but by Sun Biao. Am I right?

Zhang Wan said angrily: "Nonsense, I didn't kill him." After speaking, he lowered his head and said nothing, but he was thinking in his heart, Wang Zishan really lived up to his reputation, and he investigated the case in just a few hours.

Zhang Wanfa remembered the scene when he entered the Rose Pavilion. I can't figure it out, and I can't believe it when I say it.

Looking at Zhang Wanfa, who bowed his head and was silent, Wang Zishan continued: "What? Do you want me to show you the evidence?"

At this moment, a police officer knocked on the door and came in and whispered to Wang Zishan: "The director's phone." ”

Wang Zishan frowned, hesitated, and went out to answer the phone.

Zhang Wanfa, who remained in the interrogation room with his head bowed, had a cloudy face at this time. He had a hunch that it should be the people behind him who had exerted their strength, and it was impossible for them to let him be sentenced, otherwise there would be a lot of secrets exposed, and I don't know how many people would suffer.
