Chapter 951 Starting from the Time of Death

"The initial suspect, Mai Zuqing, went to a KTV with some people to drink that day. When he got home around 11pm, he saw the bodies of his wife and daughter and called the police. The police arrived at the scene around 11:40pm."

"Mai Zuqing worked as a cost analyst in the cost department of a real estate company, which was considered a relatively high-paying job at the time. His work was quite busy, and he often worked overtime and went out for social events. He also liked to drink. Therefore, Mai Zuqing and his wife had many quarrels. Mai Zuqing also had a precedent of hitting people, breaking the corner of his wife Sui Yingxue's mouth."

"However, Mai Zuqing is very good to his children. After talking with his colleagues, we feel that he is not the kind of murderer who would kill his daughter. Moreover, if Mai Zuqing had returned home, his mother Sui Yingxue would not have had to hide her son. Similarly, if Mai Zuqing wanted to kill his wife and children, he would not have left his son behind."

"We have collected testimonies from some relevant witnesses, and most of them support the alibi given by Mai Zuqing. Add to that the testimonies from the survivors..."

Lang Heng gave a general explanation of the case, then looked at Jiang Yuan and asked, "Do you want to meet this young man who survived?" Lang Heng asked this core question again.

The 8-year-old child is now 18 years old and can fully describe what he saw, heard and thought. On the other hand, because one of the suspects is his father, whether the young man can truthfully describe what he saw, heard and thought is another question.

However, compared to no information, false information is also useful, not to mention that there is a high possibility that the survivors are telling the truth.

"Let Meng Chengbiao talk to him." Jiang Yuan was not very good at dealing with people. This kind of witness who had been confirmed to have gone through multiple rounds of questioning was like a sponge that had been squeezed many times, and Jiang Yuan was no longer able to squeeze it anymore.

Lang Heng responded and then looked at Jiang Yuan eagerly.

Jiang Yuan was thinking, and when he looked up and met Lang Heng's eyes, he couldn't help but ask: "Lang Zhi, your expression...what do you think?"

"I don't have any ideas... I just want to see if it's possible, just by looking at the photos and stuff, to solve the case in one go." Lang Heng laughed twice.

He has seen Jiang Yuan's level of speed, so his expectations are naturally different.

Jiang Yuan was amused by him and said decisively: "That's not possible. This case is still a bit complicated."

"Okay. I thought we could get this case settled quickly." Lang Heng was slightly disappointed, but felt a little more comfortable.

If a case that their side has been working on for 8 years was solved by Jiang Yuan with just a wave of his hand, someone would really be defeated.

"But..." Jiang Yuan's voice came again.

Lang Heng's eyes widened: "But what?"

"But you guys were too hasty in ruling out this suspect." Jiang Yuan didn't give Lang Heng too much hope, and continued, "You didn't say that the suspect is the murderer. But I looked at the reasons you ruled him out, including the testimony of eyewitnesses, the testimony of the suspect's colleagues, cell phone signals, surveillance videos from the workplace, and other alibi evidence..."

"Is there a problem?" Lang Heng didn't know whether to be happy or unhappy.

Jiang Yuan's finger slid across the PAD, thinking as he spoke: "Only the alibi is relatively objective evidence. Let's not discuss other testimonies for now. The problem is that the alibi is based on the time of death, and your time of death is not very accurate. It's a bit hasty to exclude the husband of the deceased."

"Is there a problem with the time of death?" Lang Heng sat up.

"It's not a big problem, it's just not accurate enough. I think we can push it back two hours, or at least one and a half hours." Jiang Yuan marked the picture with the number he had written down before, and then said, "Look here, the windows are all closed, and the air conditioner is not on... When the forensic doctor arrived, the on-site investigators in front had already opened the windows and doors. The airflow caused by the people coming in and out must have lowered the indoor temperature by several degrees."

Lang Heng suddenly realized and said a little embarrassedly: "The on-site inspection in the early years was indeed not standardized."

The current ones are not standardized enough, but this is the working mode and management level of human beings.

Jiang Yuan naturally would not delve into the on-site investigation of the case 10 years ago. He only said, "It may be useful or not to mark the time of death more accurately. In any case, the suspect still needs to be investigated. Even if he is indeed entertaining people at night, he is free at noon."

The LV6 time of death judgment is his ultimate weapon, and he will definitely use it. Regardless of whether the suspect is the murderer, this may be used in many subsequent judgments.

Lang Heng was already excited: "If Mai Zuqing has no alibi, then he is still a big suspect... He could come here to commit the crime during lunch break, and there would be no one around Mai Zuqing during lunch break..."

"Then why kill your daughter and leave your son?" Jiang Yuan asked back.

Lang Heng thought for a moment and said, "The daughter is older now and might not agree with Mai Zuqing's opinion. He had to kill her to silence her. The son was only 8 years old at the time and might not be very sensible. Or he might not have seen the whole picture, or he might have been hidden by his mother who foresaw the danger..."

Jiang Yuan felt that Lang Heng's explanation was a little forced. In terms of sensibility, he was sensible enough at the age of 8. This can be seen from the later interrogation records. At the age of 8, he spoke clearly and expressed what he knew very clearly. As a father, Mai Zuqing should have a certain understanding of his son's language status and comprehension ability.

However, Jiang Yuan never delved into this level of reasoning.

Human beings are irrational animals. Rational reasoning can only produce trends, but it is difficult to explain whether a person would behave in a certain way at that moment in that environment.

Jiang Yuan thought about it and said, "We can follow up on Mai Zuqing's case... But you should have interrogated Mai Zuqing very clearly back then."

Lang Heng hesitated for a moment, then sighed and said, "That's true."

Although everyone involved in a murder case knows that the crime is serious and they will have strong resistance, the police's interrogation methods should not be underestimated.

Given that there were many suspicious points about Mai Zuqing, the police must have asked him thoroughly during the interrogation that day. Although there is new evidence now, to be honest, it is still too small compared to the scope of the police's suspicion.

"Does the evidence in the case still exist?"

Jiang Yuan asked another question, raising Lang Heng's expectations again.

"Yes, yes." Lang Heng said quickly, "We specially compiled the evidence for this case. Hey, back then it was Little Su who compiled the physical evidence for the special case team with a sad face, but now, in the blink of an eye, everyone has to call him Old Su."

Ten years ago, Su Shanming was probably not yet a team leader.

Jiang Yuan smiled and said, "Let's get the evidence first. Some things are better seen in person. Especially this door lock. Check to see if it's still there."
