Half an hour later.

Ye Qingzhou, who still couldn't find other bloodstains in the second bedroom where Confucius lived, had to carefully sample several places in the room where there might be fingerprints of the murderer.

Later, no signs of climbing were found on the walls outside the other windows.

"Qingzhou, tell me what you think." Xu is in the recent past, seeing Ye Qingzhou's sharper insight than ordinary people, as well as a serious learning attitude, Xiang Huamao, who did a preliminary autopsy for the three deceased, looked at Ye Qingzhou, who was always indifferent to the side.

Ye Qingzhou looked at the corpse on the ground, "It should be an acquaintance who committed the crime, and the deceased should be able to enter and leave the deceased's home freely." ”

She squatted down, as if examining the body of the first deceased, and looked at the deep depression on the back of Zhao Liren's head, "Moreover, the murderer should be an adult, left-hander who has some kind of disgust or hatred for the three deceased." ”

"Qingzhou, where did you see that the murderer is left-handed?" Ning Yelei was curious when he heard this.

Sometimes, he always feels that the eyes of the master and apprentice in front of him are as magical as if they are equipped with infrared sensors, and they can always see things that ordinary people can't see.

"They told me," Ye Qingzhou pointed to the corpse on the ground, "look ......"

"Ring, ring, ring, ......" It's just that before Ye Qingzhou could say the rest of his words, Ning Yelei's phone suddenly rang.

It was from a police officer who had previously gone to the security office to check the surveillance.

Ning Yelei listened to the report of his subordinates on the other side of the phone, and said excitedly: "Okay, arrest immediately!" ”

"I think, suspect, we've found it!" Ning Yelei looked at Xiang Huamao and Ye Qingzhou in front of him, and a hint of surprise flashed in his eyes.

"Just now, our colleagues found that Zhao Chengbi's sister Zhao Chengjin entered the community at 9:47 this morning and didn't leave until 11 o'clock."

"Moreover, the neighbors in the community, as well as the doormen in the community, all said that the relationship between Zhao Chengjin and his brother Zhao Chengbi and his parents is very poor." Ning Yelei said.

Because, whether it is from the motive of the crime or the evidence at the scene, Zhao Chengjin is very consistent with the characteristics of the murderer.

"Hmm." The expression on Xiang Huamao's face, after flashing a hint of relaxation, gradually regained his calm.

Ye Qingzhou on the side, but always felt that there seemed to be some kind of strangeness hidden in this matter, "Zhao Chengjin left the community at eleven o'clock, but Cai Shasha saw Kong Yanlan fall to her death and called the police at 11:21. ”

The time difference between the two is a little bigger.

"Will it be like the last case of Chen Xinzhen? After Zhao Chengjin finished killing someone, he suddenly found out, or suddenly remembered, that Kong Yanlan was still at home, so he avoided the camera and returned to the scene again, forcing Kong Yanlan to jump to her death? Ning Yelei's brain instantly diverged his thinking.

"Perhaps, Zhao Chengjin used some special ejection device to commit the crime." Ning Yelei flashed a lot of pictures of high-tech crimes in his mind, "The top priority now is to find the criminal suspect Zhao Chengjin first and try it well!" ”

When Ye Qingzhou heard this, he did not answer, but turned around and came to the master bedroom and looked at the deceased Zhao Liren on the ground.

According to her previous observations, Zhao Liren should have been the first victim in this closed room.

Because of his cry for help, or the sound produced by the murderer when he killed, it attracted the attention of the second deceased, Hao Jiamei.

Following the blood stains on the floor and the wall, Ye Qingzhou came to the kitchen, looking at the blood stains scattered on the corner wall, as well as Hao Jiamei's corpse.

Then, the murderer came to the living room, killed Zhao Chengbi again, and finally came to Confucius Xuan's room and killed Kong Yanlan.

All this is the order of death shown by the blood on the ground.

However, when Ye Qingzhou thought of Kong Yanlan who fell to her death, he always felt that something didn't make sense.

"Old Xiang, Qingzhou, I'll leave it to you here, I'll go back to the bureau first." Ning Yelei looked at the two people in front of him, and after saying hello, he turned around and went downstairs directly.
