Zhu Yu walked to the door and swept away with the flashlight. Sure enough, there was a check sheet covered with thick dust, almost the same color as the wall. The light in the room was dim. If you didn't look carefully, you would easily overlook it.
Zhu Yu slapped Huo Xiaofang on the shoulder: "In this way, someone has indeed been here."
Huo Xiaofang pulled him out and walked forward, "Can you hear the sound of water?" He asked.
Zhu Yu: "I can indeed hear" and then looked at Huo Xiaofang.
"In other words, the cry of the red player was probably recorded outside this room. That's why there is the sound of running water. Just now, the sound of running water was almost inaudible in the room."
Huo Xiaofang: "No, we were wrong at the beginning. The sound of water in the player is not river water, but the sound of this channel." After saying that, he took out a small tape recorder from his pocket and handed it to Zhu Yu's hand.
Then he ran to the distribution room by himself.
Zhu Yu looked at him: "Eh!" He turned on the tape recorder and saw that there was a blank tape inside. He smiled at the corner of his mouth, and Huo Xiaofang's cry came from the room, in a relatively small voice.
Zhu Yu immediately pressed the record button. Sometimes he approached the canal a little bit, and then left the canal a little bit. Huo Xiaofang's voice stopped, and Zhu Yu also pressed the stop button.
Huo Xiaofang came out from inside, and the two of them were beside the canal, putting the earphones in their ears, and pressing the play button. The two of them listened, look at me and I look at you.
Huo Xiaofang took out the tape from Tan Yaoyao's stand-alone player again, put it in, and the two put the earphones into their ears again.
"Sure enough, there is almost no difference, but He Cui, Liang Yu, and Liu Hui all say that the sound in this tape is not Tan Yaoyao's." Zhu Yu pressed the stop button and said.
Huo Xiaofang: "Under what circumstances will a person's voice change?"
Zhu Yu frowned: "I'm so tired that I'm hoarse, or I'm hoarse with a cold?? But that cry sounds only scared, helpless, not hoarse!"
Huo Xiaofang sighed: "This is something I don't understand, but I always feel that the cry should be hers. The only case of missing children that Shicheng has received so far is this one."
Zhu Yu looked at the concrete bungalow, his eyes stopped. "Fangzi, let's go in and have a look." He said and walked to the bungalow again.
Huo Xiaofang followed behind, and the two set up their flashlights again and looked at them inch by inch as they entered the door. Zhu Yu ran to the door in two steps, and when he came in, he took a branch in his hand. Huo Xiaofang looked at him, "Brother Yu, here."
The two stopped at the southwest corner of the house, where the only space was a little empty. Zhu Yu took the branches and turned over the dust with a thickness of two or three millimeters little by little on the ground.
Huo Xiaofang shot the flashlight towards the wall.
The movement of Zhu Yu's hand stopped: "Take out a material evidence bag, use a stick to pick out a long soft hair in the soil, and put it into the bag."
Huo Xiaofang's flashlight stopped at the corner of the wall. He reached out and touched the wall on the other side, and then touched the wall in the corner.
"Brother Yu, there is much less dust in the area where the two walls are connected than in other places. The white walls covered by dust are clearly exposed."
Zhu Yu walked over, squatted down and handed the bag in his hand to Huo Xiaofang, looking like it was wiped off by someone. Huo Xiaofang took the bag and said, "It seems that the harvest this time is not small."
Zhu Yu got up: "Let's go, first send this thing to the forensic department, the hair follicle is still there, it shouldn't be a problem to come and extract the DNA."
