A blurry photo, a serial murder case.

Wan Zhenghao, who is suspected of committing a major crime, hanged himself in the rental house where Xu Chuliu committed suicide a year ago, and now all the clues are broken.

The only clue left is that this rental house was rented by Yu Zhehao, which is a very critical clue and an incomprehensible suspicion.

After a preliminary autopsy at the scene, the forensic doctor Ren Qiushi found that Wan Zhenghao was disheveled and had signs of struggle.

This doesn't mean much, because when a person hangs himself, especially when his life is in danger, the human instinct for survival does struggle.

And the reason why Yu Zhehao and Jiang Zishan did not struggle was because one of them took sleeping pills and the other was drunk when they died.

Therefore, whether Wan Zhenghao committed suicide in fear of crime or homicide requires further autopsy to determine.

Now, this small rental house is crowded with police, and Jiang Tingbai is leading a technical team to conduct on-site investigation work.

"Old dog, did you find anything at the scene?" I walked up to Jiang Tingbai and asked him.

Jiang Tingbai pondered for a moment, and then said leisurely: "This rental house is full of dust, and it seems that no one has lived in it for a long time. ”

"No one lives ......" I muttered after listening to his words.

It seems that Yu Zhehao must have other plans for renting this house.

Yu Zhehao has been pursuing Xu Chuliu, and now he has rented the house where Xu Chuliu committed suicide, what is he going to do?

"It's really strange, Yu Zhehao is the first deceased in this case, could it be that Wan Zhenghao got the key to this house from him after killing Yu Zhehao, and then came to commit suicide in fear of crime?" Xue Hang said lightly.

"It's really possible, and if that's the case, wouldn't it be too much of a coincidence." I frowned, feeling that my IQ was clearly insufficient.

Maybe a criminal case is like this, it's a slow process of peeling off the cocoon, and there is no urgency.

I settled down and watched Ren Qiushi and Zeng Lan carry Wan Zhenghao's body into the body bag, and they were ready to evacuate the scene.

"Can you determine the time of death?" I asked suddenly.

Ren Qiushi looked at me in a daze, pondered for a moment, and said seriously: "The preliminary judgment is that the time of death has exceeded twenty-four hours. ”

"So long?" I was stunned and felt a little incredible.

Ren Qiushi nodded and continued: "I found some suspicious points on the body surface of the corpse, judging from the body surface, the deceased did hang himself, but there were some traces of subcutaneous bleeding on his knees, which were injuries before death. It is likely that he was threatened before committing suicide. ”

"You mean, after being threatened, he chose to hang himself?" I frowned suddenly, feeling a little puzzled.

Ren Qiushi didn't figure out the connection between these two things, and said very suspiciously: "Subcutaneous bleeding from both knees like this is a very typical coercive injury. But the strange thing is that the murderer didn't directly hurt him. ”

At this time, Li Meng, who had been beside him, suddenly spoke: "Could it be suicide at all, because tomorrow is Xu Chuliu's anniversary." During this time period, he came to the place where Xu Chuliu committed suicide, knelt on the ground and performed some kind of special ritual. In the end, he had a nervous breakdown and chose to hang himself. ”

I nodded, although what Li Meng said made sense, I always felt that something was wrong, we seemed to have missed some important clues.

If this is the case, then Wan Zhenghao committed suicide in fear of crime, he first killed Yu Zhehao and Jiang Zishan, and at the same time got the key to this rental house from Yu Zhehao. After Wan Zhenghao completed the murder plan, he came here to commit suicide. Xue Hang said in a deep voice.

"Don't jump to conclusions, let's wait until we're done with the autopsy." Ren Qiushi said lightly.

"Okay, then we'll wait for your autopsy report, old rules, you ask the dead, I captured." I took a deep breath and cast a determined gaze at Ren Qiushi.

"Section chief, the body has been carried onto the corpse truck." Zeng Lan walked up to Ren Qiushi and said seriously.

Ren Qiushi nodded, got up and left with Zeng Lan.

"It's really weird, there are no fingerprints in the whole room." Jiang Tingbai paced around the room and suddenly muttered.

"Have you checked carefully?" I looked at him and asked in a deep voice.

"The house is full of dust, and if there are fingerprints or scratches, it's easy to spot. We carefully inspected all the rooms, except for the fingerprints and footprints where Wan Zhenghao hanged himself, there were no other places. Jiang Tingbai let out a long sigh and said quietly.

"You mean, this room has been the only one Wan Zhenghao has ever entered?" I asked him puzzled.

Jiang Tingbai looked at me in a daze and nodded affirmatively: "Judging from the situation at the scene, this is the case. ”

"It seems that it really is a suicide, otherwise it would be a perfect crime." Li Meng muttered.

"How can you even believe that there is a perfect crime in the world?" I looked at her and smiled wryly.

Li Meng slowly raised his head, stared at me, and said lightly: "It's not something I don't believe in, from the perspective of criminal psychology, Yu Zhehao and Jiang Zishan are both the people who indirectly caused Xu Chuliu's suicide, that is, Wan Zhenghao's enemies." Now Wan Zhenghao killed Yu Zhehao and Jiang Zishan before the anniversary, which is considered to be his wish. A long period of psychological tension, mental tension, and sudden relief will indeed make people feel that there is nothing to love. He came here, knelt on the ground, told Xu Chuliu about his revenge, and then hanged himself, which is completely in line with the theory of criminal psychology. ”

"You have a point, and I can't even refute it. But why are you all so sure that Wan Zhenghao committed suicide? I crossed my waist and let out a long sigh.

"Do you think this is a homicide?" Li Meng looked at me squarely.

I nodded, and said something we hadn't cared about: "Now the three people in the photo are dead, but what about the person who took the picture?" That person will also be Wan Zhenghao's target. ”

"Could it be the same as Wan Zhenghao, the person who took the photo is dead, but we haven't found out yet." Xue Hang looked at me and said seriously.

Now that the case has reached a crossroads, whether Wan Zhenghao committed suicide or homicide is a very critical issue.

I paused, still holding on to my thoughts: "This case is really weird, who is the person who took the photo?" ”
