After Lei Yuyang learned the news of Shen Guanghe's death from our mouths, he was very shocked and panicked.

Perhaps for Lei Yuyang, in addition to the shock of this death, it is more regretful for the prospect of their business alliance.

Since the time of the crime was between 7 and 10:30 that night, the murderer was a burglar and an acquaintance.

What's more, Lei Yuyang left early at nine o'clock, and narrowed the time of the crime to between nine and ten and a half.

If what the nanny Xin Shuhui and Dream Fashion Jewelry owner Lei Yuyang said was true, then the murderers were locked on the two staff members of the photo studio.

And because of the lateness of the studio, Shen Guanghe was extremely dissatisfied, after Lei Yuyang left, it is very likely that the two had a quarrel after drinking, killed people with passion, and committed this tragedy.

"How is Shen Guanghe's social relationship? Does he have any enemies? I looked at Lei Yuyang and slowly asked a question.

Lei Yuyang looked at us blankly, his spirit was a little trance, and he said lightly: "We have some contacts at work, and I don't know his personal situation." ”

"Who was the assistant who went with you last night? We're also going to collect some of his biological. Li Meng looked at Lei Yuyang and said in a deep voice.

Lei Yuyang nodded solemnly, and said lightly: "He is in the store, called Qiangzi, and the employees in the store all know him, and he is the manager of my store." ”

"Okay, thank you for your cooperation, if you think of something or hear anything in the follow-up, you must contact our police in time."

After Li Meng collected biological information, our investigation and questioning ended, and after leaving a more official explanation, Li Meng and we left Lei Yuyang's office.

When we left, Lei Yuyang was still slumped in his chair and didn't come back to his senses.

Leaving the store of Dream Fashion Jewelry, Li Meng and I both took a deep breath.

"It seems that the murderer has basically been locked, and he is the person in the photo studio." I let out a long sigh and felt much more relaxed.

After listening to my judgment, Li Meng slowly shook his head: "I don't think things are so simple, even if the studio is verbally humiliated by Shen Guanghe, it won't kill anyone." Even if they kill in a drunken passion, they won't kill their whole family. ”

Li Meng's words can be regarded as pouring a basin of cold water on me, pouring a cold heart from head to toe.

"Huh?" I made a questioning voice and looked at me earnestly.

Li Meng analyzed to me as he walked: "If it is a murder of passion, the murderer will find a way to escape after the killing. And except for Shen Guanghe in the living room, the rest of the two mothers are in the bedroom on the second floor, and there is no murder. If we have to cut the roots, I think that premeditated murder is more likely than murder of passion. ”

"Premeditated murder." I muttered.

The reason why there are so many possibilities in the case is because we can't be sure that Xin Shuhui and Lei Yuyang, who are currently investigating, are telling the truth. Now everything is dead and unproven, and whether the clues they provide are true or false can only be seen if we can investigate the contradictory clues.

Now, we're going to go to Kaka Studio and investigate what happened last night.

Just as we were on our way to Kaka Studio, I received a call from Ren Qiushi of the forensic department.

"Lao Qin, after an autopsy, we finally determined the time of death at ten o'clock last night." Ren Qiushi's very firm voice came from the phone.

"Ten o'clock." I was stunned for a moment, and subconsciously muttered.

Lei Yuyang said that he left at nine o'clock, and in the middle of an hour, only two people from the photo studio were at the deceased's home, which also shows that the two people from the photo studio are the most suspicious now.

"Can you be sure of the time of death?" I immediately asked.

"I can be sure that the error between the front and back will not exceed 10 minutes. This time, we used the eye chemistry method in conjunction with the laboratory department. In order to determine the precise time of death, we examined it all night. ”

It could be clearly heard that Ren Qiushi's voice was very tired. Otherwise, according to what I know about him, he will definitely ask me for credit if he makes such a big effort, and he will have to ask me to invite him to a barbecue.

"Lao Qin, I've been working all night, you have to invite me and Zeng Lan to have a meal."

As I expected, even in his current state, Ren Qiushi did not forget to ask me to invite him to dinner.

"No problem, after the case is solved, let's have a meal together." I tried to pull myself together and said to him with a smile.

Immediately afterward, I continued to ask him, "Did you find anything else from the autopsy?" ”

"There was only one wound on the body of the deceased, which was absolutely fatal. Other than that, no suspicious trauma was found, including but not limited to coercion, resistance, or restraint. Ren Qiushi was already very tired, these words were what he would say every time he performed an autopsy, and they were completely his mechanical answers.

Ren Qiushi paused and continued: "The male deceased had a lot of alcohol before his death, and his blood alcohol content had reached 100 milligrams, which was a drunken state. The blood level of the female deceased was low, only 40 milligrams, and there were no abnormalities in the body of the young deceased. Drugs, hallucinogens and poisons were not found in the bodies of the three deceased. ”

"In a drunken state, then the traces of the fight at the scene are likely to be faked by the murderer, or unintentionally caused by the deceased while drunk." After listening to it, I took a deep breath and analyzed.

"It is very likely that if the deceased was drunk and an acquaintance committed the crime, he would not have taken precautions." Ren Qiushi agreed with me very much and said slowly.

"Can the male deceased be in a drunken state to send a text message?" I thought about it for a while, and suddenly asked Ren Qiushi.

If Shen Guanghe was already drunk and unconscious, then that text message might have been sent by the murderer.

But this is a very critical question, but Ren Qiushi has no way to give me an accurate answer.

"Everyone's alcohol tolerance is different, which is related to the degree of acetaldehyde dehydrogenase secreted by the human liver, just like some people pour a glass, and some people don't get drunk with a thousand glasses. This matter varies from person to person, and there is no way to judge the amount of alcohol that Shen Guanghe has. However, in terms of blood alcohol content, 100 milligrams is enough to make the population slurred and unconscious. Ren Qiushi explained his views to me seriously.

"Okay, I see, if you find anything, let me know in time." I nodded and said lightly.

"Okay, then come on, I'm going to catch up on sleep." Ren Qiushi yawned and hung up the phone.
