Sun Jian was a smart person. He was very confident in the " perfect murder " he had designed.
He was confident that even if the police suspected him, they wouldn't be able to do anything to him. Firstly, he didn't appear at the crime scene. Secondly, he didn't order anyone to kill Jian Ning.
Therefore, even though the police had found him stealing cyanidation from the chemical plant, he still refused to plead guilty to murder.
Indeed, if Sun Jian insisted that he stole the cyanidation to make money, the police could only charge him with theft.
It was indeed difficult to convict him of murder based on this evidence alone.
"Where did you put that bottle of cyanidation?" Ling Yufei continued to ask Sun Jian.
"Oh, you mean that bottle? When I brought it back, I was afraid that my daughter would play with it at home. I thought that it was a highly toxic substance, so I threw it away. Then, I poured it into the river and threw the bottle away.”Sun Jian said indifferently.
"I think you're really crazy! Aren't you afraid that the people swimming around will be poisoned by accidentally eating such a poisonous substance?”Ling Yufei became angrier as she spoke.
"Officer, the place where I poured it was very remote and no one was swimming there. Moreover, it was just a small bottle of something. It had long been diluted by the river water!”Sun Jian said disapprovingly.
Sun Jian's words were not without reason. The small bottle he had poured into the river should have been diluted and its toxicity greatly reduced.
But Meng Fan could tell from his expression that he was lying. If he had really poured cyanidation into the river, Jian Ning wouldn't have died from poisoning.
Meng Fan guessed Sun Jian must have hidden the cyanidation!
"How old is your daughter?" Meng Fan suddenly asked.
Sun Jian was surprised to hear Meng Fan ask about his daughter.
Even Ling Yufei didn't understand why Meng Fan suddenly asked this.
"Two! I just learned how to speak!" Speaking of his daughter, Sun Jian's expression seemed to soften a lot.
"You and You Hui have to work. Who's going to take care of the child?”Meng Fan continued to ask.
"We hired a nanny to take care of her!”At this moment, Sun Jian was somewhat relaxed.
"There are good and bad nannies nowadays. Aren't you afraid that she will abuse the children at home?”Meng Fan showed a concerned expression.
"Don't be afraid. I've installed cameras in every corner of the house. When I'm worried, I'll take a look at my phone!”Sun Jian said with a smile.
"Then turn on the remote surveillance video and let me see! I want to see how the quality of the network surveillance video is now.”
Sun Jian took out his phone and opened the remote surveillance video in his house.
The surveillance video showed that the nanny was playing with Sun Jian's daughter in the living room.
"The picture quality is quite high definition!"
"Of course! I spent a lot of money to buy this high-end stuff!”
"Nowadays, surveillance videos are usually uploaded to the cloud. The one you bought should have this function too, right?”Meng Fan asked with a smile.
"Yes! Of course! Sometimes, when I'm too busy, I'll occasionally pull up the surveillance footage from the past to see if the nanny abused my daughter!”Sun Jian said with a smile.
He seemed to have endless things to say about his daughter.
"Before Jian Ning died, did you still have the surveillance video in your house?”Meng Fan suddenly asked.
Sun Jian's expression froze. He was terrified and nervous.
This was the effect Meng Fan wanted. Sun Jian's expression told him that there was something fishy about the surveillance video.
Meng Fan looked at the one-way mirror in the observation room and gestured to Zou Bo, who was observing in the observation room. Zou Bo immediately understood what Meng Fan meant.
When interrogating criminals, it was sometimes inconvenient to speak, so they would usually use hand signals to convey their intentions.
Meng Fan's gesture meant that Zou Bo had to send someone to replace him and continue the interrogation.
Zou Bo asked Kong Xiao to replace Meng Fan.
"Sun Jian, your phone may contain evidence of your crime. We need to confiscate it for inspection!”Meng Fan stood up.
Meng Fan confiscated Sun Jian's phone and walked out of the interrogation room, while Kong Xiao and Ling Yufei continued to interrogate Sun Jian.
Meng Fan took Sun Jian's phone and walked to the observation room.
"Meng Fan, did you find any clues?”Zou Bo hurriedly asked.
"You can say that, but this Sun Jian is more cunning than I imagined! I originally wanted to see if Sun Jian had done anything unusual to You Hui from the surveillance video in his house before the incident, but he deleted the video from the day before the incident!”Meng Fan said.
"Is there really nothing we can do about him?”Zou Bo looked worried.
"Ji Lei, take a look. If he deleted the surveillance video uploaded to the cloud, is it possible to recover it?”Meng Fan looked at Ji Lei, the Internet genius from Serious Crime Division Two, who was working in front of his computer.
"Let me take a look first?"
Ji Lei took Sun Jian's phone and fiddled with it for a while before saying,""There's no way to recover the videos he deleted previously, but I found that his surveillance app was implanted with a trojan horse by a hacker. His cloud surveillance video has long been hacked!”
"Is there any other way to retrieve the video that was deleted by Sun Jian?”
"It's not like there's no other way. Nowadays, after many hackers hack into other people's cloud, they will sell the surveillance videos to some voyeurs. They will usually upload the surveillance videos they obtain to their own servers and store them for a period of time. Simply put, if I hack into the server where the hacker stores the surveillance videos, I might be able to retrieve the videos that Sun Jian deleted!”Ji Lei continued.
"Then hurry up and try to hack into the hacker's server and get the video back!”Zou Bo hurriedly said.
"Good! This is not difficult, but I need some time. Ten minutes is enough!”Ji Lei said confidently.
Sure enough, in less than ten minutes, Ji Lei retrieved the surveillance video that Sun Jian had deleted from the day before the crime.
In order to quickly finish watching the surveillance video for the entire day, Meng Fan decided to exchange for the Level 2 Divine Eye skill at the Divine Detective System store.
Previously, he had obtained the beginner Divine Eye skill, which could only look for clues by watching videos at five times the speed. Now, the level two Divine Eye skill was much more powerful. It could look for clues by watching videos at a hundred times the speed.
In other words, Meng Fan could easily watch the 24-hour surveillance video in less than 15 minutes, and he could even know every detail.
After watching the surveillance video deleted by Sun Jian with his level two clairvoyant skill, Meng Fan's lips curled up as he walked into the interrogation room with confidence.
Seeing Meng Fan enter, Kong Xiao stood up and gave way to Meng Fan. He knew his role was to stall for time so Meng Fan could think of a countermeasure.
Now that Meng Fan had come in, he knew Meng Fan must have found some powerful clue.
And Meng Fan had indeed made a major discovery in the surveillance video!
