Regarding Ning Yelei's statement, Xiang Huamao did not give an affirmative or negative answer.

In the room of the deceased's family, including all the tools of the crime and the door lock, no fingerprints other than their family and Zhao Chengjin were found.

If a murderer not only poisoned himself for a long time without being discovered, but also after killing four people in a row, he can still do this without leakage, and it can indeed be called a certain anti-reconnaissance capability.

It's just that the blood stains in the room and the poison in the deceased's body made Xiang Huamao feel too abnormal.

"The case of Zhao Chengbi's family of four should have been committed by an acquaintance, and this left-handed murderer was able to freely enter and leave the deceased's home and community without being suspected by others."

"Team Ning, you can first focus on the people who have been in and out of the deceased's community today and meet the above characteristics."

"Moreover, the murderer should be an adult who has some kind of disgust or hatred for Zhao Chengbi and his parents."

As Xiang Huamao spoke, his mind quickly flashed back to the messy living room, master bedroom, and cramped but neat second bedroom of the victim's home, with almost no traces of blood.

"The murderer and the ......" Xiang Huamao suddenly remembered the photo on the head of the bed, but he couldn't remember the other party's name for a while, "The younger brother of the deceased Kong Yanlan should also have an intersection!" ”

"That teenage boy, where is he now?" From the time they rushed to the scene, five or six hours have passed now, and Xiang Huamao's entire mind is on the scene and the deceased, and he has forgotten Kong Yanlan's younger brother who survived because he went to the Children's Palace to make up for classes.

"You're talking about Confucius Xuan!" When Ning Yelei spoke, he patted his head, "I asked Xiao Liu to go to the Children's Palace to pick up the child. ”

However, when he turned around and walked around the criminal police brigade, he didn't find Xiao Liu and Confucius Xuan.

Ning Yelei instantly panicked in his heart, for fear that the child would encounter something unexpected, when he picked up the phone, "Xiao Liu, where are you?" What time is it? What about Confucius? ”

"Team Ning, I searched around the Children's Palace, but I didn't find Confucius Xuan, just now I asked a few teachers in the Children's Palace, saying that he had been taken away by a very good-looking man." On the other end of the phone, Xiao Liu's anxious voice came.

When Ning Yelei heard this, his heart tightened for no reason, he just wanted to call the rest of the team to continue to search for the whereabouts of Confucius Xuan, but he saw Ye Qingzhou walking over with a little boy about ten years old.

The boys have very white skin, but they are obviously thinner and thinner than their peers.

There was also fear of an unfamiliar environment in his eyes, and the corners of his eyes were slightly red because of the crying he had just cried.

"Where's my sister?" Although Confucius Zixuan had been holding back tears, as soon as he spoke, his voice was still full of crying, "I want to take another look at my sister." ”

"Team Ning, I brought Confucius Xuan, and the rest of the matter will trouble you." When Ye Qingzhou spoke, he looked at Ning Yelei in front of him.

Compared with watching a child in his teens and about ten years old, facing the fear, sadness and helplessness of losing his loved ones, Ye Qingzhou is more willing to seize the time, find the murderer, and give an explanation to the dead and the living.

"Hmm." Ning Yelei took Confucius Xuan's hand from Ye Qingzhou's hand.

Ye Qingzhou glanced at Xiang Huamao on the side, and immediately followed.

"Qingzhou, did you find something?" As a forensic doctor's professionalism and the intuition of getting along with Ye Qingzhou these days, Xiang Huamao always felt that Ye Qingzhou must have found something.

"Teacher Xiang, I know it might be a little unbelievable to say this." Ye Qingzhou's bright and clear eyes looked seriously at this professional forensic doctor who has been practicing for more than ten years, "The murderer who killed Zhao Chengbi's family should be here with us now." ”
