What the?

When the old police officer heard this, they were all shocked and asked excitedly, "Are you sure?"

Zhong Changan said in an unbelievable tone: "You really have to find evidence of the deceased's murder?"

Zhou Zheng nodded, his expression a little heavy and said, "How can I be joking about human life." ”

When Zhong Changan heard this, in addition to being shocked at this moment, he was more surprised!

Zhou Zheng offered to take a look at the scene of the crime, which made him a little confused, and at the same time asked him to give it a try with a dispensable attitude.

After all, Zhou Zheng's previous help left an unusual impression on him, but Zhong Changan didn't have much hope, because none of the specially trained police officers in their police force found any clues, and I am afraid that it would be difficult for him to find out.

But it turns out that Zhong Changan was wrong!

In just ten minutes, Zhou Zheng brought him a surprise, and this surprise was not small at all!

A place that even their professionals didn't find was discovered by Zhou Zheng, and this insight is simply terrifying!

At this time, Zhong Changan, who was the first to react, coughed lightly and suddenly said: "Xiao Zhou, the police need evidence to handle the case." ”

Several police officers who were in shock came back to their senses, nodded when they heard the sound, and looked at Zhou Zheng.

When Zhou Zheng heard this, he showed a confident smile and said, "Evidence?

With that, Zhou Zheng returned to the location of the crime on his own, and Zhong Changan and several others also followed closely behind his buttocks.

Under the attention of everyone, Zhou Zheng came directly to the bottom of an air conditioner, pointed to the bland plug on the ground, and said: "I have looked at the whole room, and only this place makes me very strange." ”

Hearing this, the female police officer who followed Zhou Zheng into the room just now remembered that it seemed that Zhou Zheng had indeed stayed in this plug place for a few minutes.

But what's so curious about it?

Zhou Zheng looked at the people with a hooded face, the corners of his mouth turned up slightly, and then said: "For ordinary families, the plug is generally plugged into the socket, and the plug will not be pulled out for no reason at all!"

Xiao Zhang, who was standing on the side, was still a little puzzled, and said, "Isn't it normal to pull out the plug?"

"It's not normal!"

When Zhou Zheng heard this, he directly denied Xiao Zhang's conclusion.

At this moment, Zhong Changan, who had been silent, suddenly spoke: "The deceased is about one meter six tall, but the position of the air conditioning plug is about two meters, with her size, it should be a very troublesome thing to pull the plug, so if you can try not to pull it out, you will definitely not add trouble to yourself." ”

At this time, Xiao Zhang seemed to understand something and nodded.

At this time, the only female police officer asked, "Maybe the deceased has been unplugged in order to save money?"

When Zhong Changan heard this, he nodded: "There is indeed such a possibility!"

Zhou Zheng glanced at everyone and smiled: "What you said is right, but I can tell you for sure that this air conditioner plug was only unplugged today, and it will definitely not be more than two hours before the deceased dies!"

As soon as these words came out, everyone was shocked again!

"Impossible!"

Before Zhou Zheng could finish speaking, the old policeman said in a deep voice: "According to the forensic examination, the deceased has been dead for more than four hours, and the plug of the air conditioner cannot have been unplugged two hours ago!"

"Why is it impossible?" Zhou Zheng asked rhetorically when he saw this.

"It just can't be, unless there was another person in the room two hours ago!" the old police officer said forcefully.

"That's right, there's one more person in the room!"

Zhou Zheng's tone was very firm at the moment, and he had been discussing around the plug for a long time, in order to lead to this sentence.

Zhong Changan's face changed when he heard this, and he frowned and said, "Xiao Zhou, you mean that person is the murderer!"

Zhou Zheng nodded and said, "That's right!"

"This is just your reasoning, and the evidence is the foundation of the investigation. ”

The old police officer was still a little unconvinced at the moment, thinking that this was just an inference from Zhou Zheng, and there was no evidence at all.

"Of course there is proof!"

Zhou Zheng said very confidently, and walked towards the window as he spoke, and after coming to the window sill, he pulled up the curtains, and the room was suddenly much brighter at this time.

He pointed to a potted plant with pale white flowers on the windowsill, turned to the crowd and asked, "Do you know what kind of flower this is?"

Xiao Zhang, who was standing on the side, said, "It should be a flower used for decoration!"

"This is called cherry blossom grass, what kind of decorative flowers?" At this time, the female police officer finally found an opportunity to hit Xiao Zhang and said directly.

“……”

Everyone was embarrassed for a while, Zhou Zheng nodded when he heard this, and said: "That's right, this is indeed cherry blossom grass, and this is also the only trace left by the murderer, I have to say that this guy's crime process is perfect, but he shouldn't, he shouldn't leave this pot of cherry blossom grass, this will be the biggest mistake he made." ”

"Why do you say that?" Zhong Changan asked.

Zhou Zheng looked at the bewildered crowd, shook his head, and said: " Cherry blossom grass has a characteristic, its petals will change with the change of temperature, if the temperature is about 20 degrees, then the color of the cherry blossom grass is red, but if its color becomes white, then it means that the surrounding temperature exceeds 30 degrees, I don't know if you have found it, the weather today is cloudy, take out your mobile phone to see, the temperature outside today will not exceed 20 degrees, then let me ask, since the air conditioner has been unplugged, then why is the color of the petals white!"

Hearing this, everyone showed a thoughtful look.

Zhong Changan also showed a thoughtful expression on his face, and after a while, he slowly spoke: "You mean corpses?"

Zhou Zheng smiled and said, "That's right, the temperature in the room was changed by the murderer by adjusting the air conditioner, and his purpose is very simple, that is, to make the forensic doctor make a wrong judgment when doing an autopsy, so as to disrupt your thinking of handling the case." ”

"Director Zhong, what are you talking about, why do I not understand the more I listen!" said the female police officer with a puzzled face.

When Zhong Changan heard this, he immediately explained: "Because of the different temperatures, the speed of the corpse's decay will be different, because the forensic doctor ignored the air conditioning when making a report, so he made a four-hour death time, but in fact, under the effect of high temperature, the body of the deceased may have just died for an hour or two!"

Hearing this, the young police officer Xiao Zhang said with some excitement: "That means that the surveillance video we watched four hours ago will not have a picture of the murderer at all." ”
