An hour later, the mountains and seas were built.

Xiao Zeng has been here for most of the day, and he is quite familiar with the scene, so he came to Xu Da far and near.

said the results of the investigation of Mr. Chen, and sure enough, he was also extorted a sum of money, and the conditions for leaving were even more unbelievable, helping her find a home and continue to be a senior nanny.

Xu Dayuan asked Xiao Zeng to contact the nanny Liu Yinuo, whether she was a chicken or a nanny, at least verify the time of the eucalyptus, and then Xu Dayuan left, and brought a lot of people.

Da Zhao looked at the direction of the car and kept shaking his head.

"The leader is on top."

"I guess we want to check Luo Qian, we have some preconceived ideas, and we always feel that this person takes the initiative to help Dong Chengwen fight the lawsuit, so there is a little less suspicion about her, but the investigation is not a guess, we have to find out every suspect.

Okay less nonsense, let's start working, although the backyard was surveyed last time, but nothing was found, if people stand in the backyard and throw Molotov cocktails, there will be traces to follow, we will search for monitoring dead ends this time. ”

Several people nodded one after another, and Yang Xuetong took Zhu Xingxing and Sun Gaotie and walked towards the other side of the shrub wall, after all, if you want to search in a carpet way, you can't let go of any corner.

Da Zhao didn't participate, grabbed a pebble on the ground, stood on the northernmost edge of the bushes, and glanced at the monitoring position, which was completely impossible to see here.

Raising his hand, he threw it towards the window of the cloakroom on the second floor, and with a whoosh, the pebbles flew into the window, and it was against the upper edge of the window.

Zhou Ning glanced at it, Da Zhao don't look at his physique, but he is not strong in strength, when they wrestled their wrists before, Sun Gaotie easily won him, since he can throw it in, women should be able to do it too.

Zhou Ning picked up a pebble and called Zhu Xingxing over, Zhu Xingxing looked confused, thinking that he had done something wrong, and looked at Zhou Ning cautiously.

"What's wrong, team leader?"

"Here, follow the example of Da Zhao just now, throw the stone into the cloakroom window, and try if you can do it?"

Zhu Xingxing sighed, stood in Da Zhao's position, and with a slight throw, the stone flew into the room.

"If you throw a two-pound object and stand in the farthest northeast corner, do you think you can throw it in?"

Da Zhao was interested, he knew that Zhou Ning wanted to test whether a woman could complete this action.

"Wait, I'll find you something."

Saying that, he ran away quickly, and after a while, he came back with a large mineral water bottle and stuffed it directly into Zhu Xingxing's arms.

"It's not that right, it's 1.3 liters, why don't I drink some?"

Zhou Ning glanced at him, and before he could speak, Zhu Xingxing was already standing in the northeast corner and raised his hand and threw the bottle into it, without touching the window frame at all.

Da Zhao looked back at Zhu Xingxing, and was directly dumbfounded, looking up and down at Zhu Xingxing.

"Look at how thin you are, why are you so energetic?"

Zhu Xingxing looked confused and looked at Zhou Ning suspiciously.

"Team leader, should I throw it in or shouldn't I throw it in?"

Da Zhao raised his head and laughed, and when he had laughed enough, he dragged Zhu Xingxing to get out of the way.

"What Zhou Xiaozhou means is, find a girl to try, is it difficult to throw at this height, you lose it too easily."

Zhu Xingxing rubbed his nose and stalked his neck towards Da Zhao, losing the stunned state just now.

"Explosive men are naturally dominant, but this kind of throwing doesn't require a lot of force, not to mention doing forensics, that is, the little nurse breaks the ampoule every day and throws it in the trash, the accuracy can't be compared with ordinary people, and the teacher, the power of the chalk head, don't say you haven't tasted it?"

Da Zhao rubbed his nose and lowered his head, but Zhou Ning nodded affirmatively.

"Xiao Zhu is right, professional habits and behavioral habits are indeed an aspect of consideration, but we have been experimenting for a long time, and the monitoring before and after this angle cannot be photographed, but how to leave this courtyard? Climb over these bush walls? ”

In a word, several people looked at the shrub wall, this community has been built for three or four years, these shrub walls are very tall and airtight, the middle is a layer of iron fence, the periphery is surrounded by shrubs to grow, not to mention summer, even winter can not see the outside at all, such a double-layer structure, how can people just find a gap to go out.

"I said Zhou Xiaozhou, don't think about it from the shrub wall, there are no gaps, and it is even more impossible if you turn over, I can't touch the top at my height, how can I climb over? Besides, I turned it over, and the monitoring saw that this direction was wrong! ”

Zhou Ning stared at the north door of the villa, this door is a stainless steel security door, with double glazing, quite delicate and beautiful, although this location is under the cloakroom, but the fire did not engulf here, so the glass on this door is not broken.

"Have you taken your fingerprints at the North Gate?"

Yang Xuetong walked over, raised his hand and said:

"I collected it during the last survey, and no fingerprints were found on the north gate."

Yang Xuetong nodded very affirmatively.

"I didn't find any fingerprints, there was dust on the handles inside and outside the door, I scanned them and collected them, and I only found some marks of circles, not traces of thread gloves or latex gloves.

I made a record, and when I put it together, there was no option in the form, so I didn't fill it out at the time, but it can be concluded that the door was carefully cleaned before the fire, team leader, you see. ”

Yang Xuetong's voice was getting smaller and smaller, and he felt that he had not reported it in time without a special discovery, and he was a little unconfident at this time, Zhou Ning did not say a word of reproach, and enlarged the tablet picture he handed over.

This trace is not big, the length is not more than 1.7 cm, there are irregular points on it, and the traces of rubbing, Zhou Ning thought for a while, and his eyes lit up.

"It's the imprint of the towel, whether it is a latex glove or a line glove, which appears abruptly at this fire scene, and the towel imprint is different, and it is easy to be ignored as a trace of cleaning.

Da Zhao came over and extracted the traces, Zhou Ning closed his eyes, and there seemed to be a person in front of him, covering his face with one hand and a towel in the other, opening the door and rushing into the villa, and then went downstairs directly and left from the garage, Zhou Ning opened his eyes and said firmly:

"After throwing Molotov cocktails, if you want to not be recorded by the surveillance, it is not realistic to walk through the main entrance or over the wall, then there is only one way left, enter through the kitchen door, and then leave through the basement, as long as you avoid the surveillance, you can't leave a trace."

Zhou Ning paused, Da Zhao looked incredulous, pointed to the north gate and said:

"There's a lock on this."

Zhu Xingxing's face was excited, and she took the first step and said:

"I think there will be no fewer people with keys, two nannies, Dong Chengwen, Fang Hua, and property stewards, of course, such a big house will never have a spare key, right?"

Zhou Ning squinted, spare key?

Don't forget about this stubble, at that time, in the utility room on the first floor, there was a wall with a lot of things, and the gas ticket was found there.

Yang Xuetong stretched his head and said suspiciously:

"If you leave the garage, can you not be photographed by the surveillance? On June 29th, all the extracted surveillance, not to mention the Jingkou Branch, Xu Da, they also screened it several times, and they didn't find anyone going out of the underground garage? ”

Zhou Ning waved his hand and dialed Xiaoqu's phone.

"We're in the mountains and seas, we need to do an experiment, you said before, I let people do something, you can remotely control and monitor, right?"

"Yes, I gave Sun Gaotie a box similar to a power bank at that time, and asked him to go to the monitoring room, and I told him how to plug it in."

"Okay, you can find us from the surveillance in a while, compare it with the surveillance on the previous 29th, and see if you can see us."

Hanging up the phone, Sun Gaotie had already raised the bag in his hand, just now Zhou Ning was on the phone hands-free, he knew that it was time for him to play, and he was very excited to be able to complete one thing alone.

"Team leader, I'm going to the monitoring room, and Brother Qu has already told me what to do."

Zhou Ning nodded, Sun Gao Tie ran away, several of them put on shoe covers, finished arming, entered the villa through this north door, Zhou Ning pressed the timer on his mobile phone, bypassed the staircase, and went straight to the utility room.

Next to the platform where Dong Chengwen's coat was found, there was a message wall with several small hooks on it, all of which were in the shape of artistic antlers, and three sets of keys were hung, one of which had self-adhesive stickers on it.

Zhou Ning took it down and looked at it one by one, it marked the back door, garage, master bedroom, study, children's room, guest room, obviously this is the spare key, although the other two sets are not marked, but the keys are exactly the same.

"Sure enough, there's a spare key."

Yang Xuetong opened the physical evidence bag and threw the three sets of keys into it, but it is unlikely that any clues will be found on it, they all know that the murderer's anti-reconnaissance ability is very strong, and they all know that there is a towel to open the door, how can there be any traces left on it.

"Throw the Molotov cocktail, then send the spare key back, go straight downstairs, let's go down and have a look."

Several people followed Zhou Ning downstairs, passed through the security door on the negative floor, and came to the garage, Zhou Ning glanced at the time, they stayed for a while, and it only took a minute.

Zhu Xingxing was about to press the button of the roller shutter door on the wall, but Yang Xuetong stopped her.

"Forensic Dr. Zhu, don't worry, I'll take a sample first."

Da Zhao waved his hand.

"I have sampled here, and the fingerprints of Fang Hua and Dong Chengwen were found on the button, as for the handle of the door, there are also palm prints of the two of them, as well as some circle-like traces, according to Zhou Ning's analysis, I am afraid that the murderer pads the handle with a towel and opens the door, but why can't the monitoring take pictures?"

Zhou Ning opened the security door.

"Don't worry, just try it!"
