Seeing the crime scene flashbacks made me the darling of the police station.

Chapter 384 provides ideas
Qin Chengyuan's car was parked next to the entrance of the Municipal Bureau.

Su Miaoyi left the Municipal Public Security Bureau, looked around, saw his car, and quickly ran over and got into the passenger seat.

"Dad, why didn't you call me?" Su Miaoyi asked.

Qin Chengyuan was taken aback by her calling him, then laughed: "I was worried about disturbing your work."

"What if I don't check my phone all night?" Su Miaoyi said.

Qin Chengyuan looked at her: "Do you think I can't get into this place?"

Su Miaoyi pursed her lips and remained silent.

"I'm here mainly to see you, so I won't disturb anyone else," Qin Chengyuan said. "But if you don't come out, I can go in and check on you."

Su Miaoyi smiled.

Qin Chengyuan took a box of pastries, opened it for her, and then took two small cakes, opened them, and placed them on the armrest box. He also opened the packaging of the fork: "Have you had dinner tonight?"

"Not yet." Su Miaoyi put a piece of hibiscus pastry in her mouth. "I don't think I washed my hands."

Qin Chengyuan found her another pack of alcohol wipes: "If Yan Zhou were here, she would look disgusted again."

After wiping her hands, Su Miaoyi picked up a fork and ate a small cake: "Dad, did you hear? On Saturday, my brother and I were fishing and we caught body parts. He doesn't want any of his things anymore."

Qin Chengyuan smiled and said, "Yan Zhou has always been a clean person. Eat slowly."

“There’s been no progress on the case. I have to go back as soon as I finish eating,” Su Miaoyi said. “The dismemberment case in the river was progressing, but other cases have emerged along with it. Now it’s very likely that the murderer has become the victim. The DNA hasn’t come out yet, so it’s still uncertain.”

"You haven't had a break in a long time, have you?" Qin Chengyuan asked, looking at her.

"I slept for a while this morning," Su Miaoyi said.

Qin Chengyuan looked at her.

Su Miaoyi glanced at him: "Feeling sorry for him?"

Qin Chengyuan didn't say anything, but unscrewed the thermos and poured her some hot tea: "Shilan brewed this tea. She said it's good for the body, but I don't really know much about it. I brought quite a lot with me. I'll take it upstairs in a bit and brew some for them to drink, something hot."

"Ah."

“Shilan originally wanted to come too. But she and her students wanted to discuss their papers via video,” Qin Chengyuan said.

"I'll go home for a few days after I finish this case. I was planning to go home this weekend, but I didn't expect to run into this case."

"You go about your business, the family isn't going anywhere," Qin Chengyuan said. "Your health is the most important thing."

"Okay." Su Miaoyi ate both cakes, then half a box of pastries. When she was almost finished, she said, "Dad, how do you think people avoid surveillance cameras that have no blind spots?"

"Complete surveillance coverage?" Qin Chengyuan said.

“It’s practically spotless,” Su Miaoyi said. “Because there are streetlights at night, if someone passes by in a place that the surveillance cameras can’t reach, the cameras can capture their shadow. But there’s nothing on the cameras.”

Qin Chengyuan thought for a moment and said, "What about the time frame? Is it accurate? Or are there any less noticeable places that could be bypassed by surveillance? Especially those places that seem impassable. Maybe the murderer has already tampered with the area to make it passable, but they just haven't noticed."

"The places we can't get through... we'll just have to go back to the site and check again," Su Miaoyi murmured.

“It’s normal to check the scene multiple times,” Qin Chengyuan said. “Because you have special abilities, your efficiency in solving cases has increased, and many complex things have become much simpler. But solving a case is a very tedious process that requires repeated deduction and observation.”

Su Miaoyi nodded, thinking about his words. After a few seconds, she said again, "Timeframe? There was a party at the villa, so the murder must have happened after the party ended."

She muttered to herself, then suddenly sat up straight: "There's a problem with the time frame."

Qin Chengyuan looked at her.

"Dad, I have to go now. Drive carefully on your way back and let me know when you get home," Su Miaoyi said as she got out of the car.

"Wait a minute, wait a minute." Qin Chengyuan also got out of the car and told her to take the thermos. He then took a few bags of things from the back seat. "You haven't eaten dinner, have you? Take these back so everyone can have something to eat."

"Okay." Su Miaoyi took it. "I'm leaving." "Take a rest when you have time," Qin Chengyuan said.

"Know it."

Su Miaoyi carried several bags of food upstairs.

Zhuang Yanzheng and Qi Feng were both surprised to see her.

Qi Feng, who was nearby, quickly took it.

Zhuang Yanzheng also walked over: "Wow, magic?"

Su Miaoyi: "."

The things were all on the table. She said, "My dad just arrived and asked me to bring these up."

"Director Qin is here?" Zhuang Yanzheng's expression instantly turned serious.

“They’ve already left,” Su Miaoyi said. “Let me share this with everyone. There are tea bags inside, so everyone can have some. My mom said it’s good for your health. I’ll go check the security footage first.”

She left quickly after she finished speaking.

Fortunately, we were able to copy all the surveillance footage from Friday night.

They only watched the surveillance footage after the party ended.

However, the murderer may have already gone to the vicinity of the villa, or even entered the villa, before their party ended, and was waiting for them to finish.

Su Miaoyi told everyone about this, so everyone took turns watching all the surveillance cameras on the streets in front and behind on Friday night, at different times and on different cameras.

She watched from the surveillance camera as several people attending the party entered the villa, and then watched Duan Zhixi leave the villa.

For the next two hours, the surveillance footage showed people coming and going, either nearby residents returning home from get off work or students returning home.

She watched the surveillance footage on the front street at double speed but found nothing. Just as she was about to watch it again, the person in charge of watching the back street suddenly said that he had found something.

At 11:01:23 PM on Friday night, a shadow was seen entering the back street intersection on the surveillance camera.

I didn't get any photos of people, just their shadows.

However, unlike the shadow that flashed past in front of Guan Zhou's villa, this surveillance camera captured the entire process of the shadow entering the back street.

Judging from the shadow, the person kept turning their head back and forth, looking around, and was deliberately avoiding the surveillance cameras.

After entering the back street, they walked all the way to He Bin's villa.

He Bin's villa was locked, and the street surveillance cameras didn't capture everything. Therefore, there is no surveillance footage of the section near He Bin's villa.

Su Miaoyi calculated the speed of the shadow, the length of He Bin's villa, and then checked the surveillance footage outside another villa in front of her based on the estimated time. She didn't see any more shadows or people.

It can be concluded that this likely entered the villa from the backyard of He Bin's villa.

After that, the nighttime surveillance footage didn't capture anything else.

This person may have stayed in the villa until dawn and did not come out.

We've already reviewed some of the surveillance footage from Saturday daytime, but we still need to continue reviewing it.

There are just too many surveillance videos to watch.

Even though it was divided into segments for everyone to watch together, it still took all night to finish watching it.

It was already daylight outside.

Su Miaoyi looked at the places the shadow had been on the surveillance footage and decided she had to go there herself to see if she could find anything.
　Goodnight everybody
