"Let's make a copy of the surveillance video," Ning Hui said to the police, "Contact me as soon as there is news about the property", and the police nodded in a gesture

"Where do you go next?" Yu Ya looked at Ning Hui

"The girl's clothes in the surveillance are not white skirts, there are no clothes on the rooftop, and the suspect in the second surveillance is not holding anything in his hand, it is estimated that he was thrown somewhere, look for it" Ning Hui said "Let's go and see the distribution of surveillance first, take a look at the blind spots of surveillance, and walk through it from the perspective of the murderer"

Yu Ya nodded, and the two of them immediately walked to the rooftop, and began to calculate the psychology and route of the criminals from the rooftop

"Go down the stairs from the rooftop, and after reaching the first floor, you can go out through the fire escape door to avoid the surveillance at the entrance of the building."

"After coming out of the fire escape, go to the right, and then there will be a camera about 100 meters away."

"Go to the left about 100 meters to the intersection"

"Stand at the intersection and walk to the left, and then there will be a camera about 100 meters"

"Stand at the intersection and walk straight, about 200 meters or so is the wall, there is no camera all the way, and then walk in the direction of the gate, there is only one camera left at the gate"

"This is probably the route the suspect left and entered," Ning Hui said

Yu Ya nodded after the record, but then expressed her doubts, "There are no trash cans along the road, and there are cameras in all the corridors, so it is impossible for him to throw them, in the corridors along the way, the trash cans will only be cleaned at night, and there are no tree ditches or anything like that, can this dress disappear out of thin air?" ”

"I don't know, we're just a bunch of high school students, how do we solve the case?" Ning Hui smiled bitterly, "And basically rely on TV dramas, online dramas, and novels to understand this aspect, and this murderer can disappear for ten years, which proves that he has no clue about him, and there are ......"

"Dingdingding......dingding"

A phone ringing interrupted Ning Hui

"Your call" Ning Hui looked at Yu Ya, "Let's take it first"

After Yu Ya picked up the phone, she looked at her phone, which showed Naranno "called by Nono" and then turned on the speakerphone

"Hey Nono"

"Is Ning Hui with you, Yaya?"

"Together with us"

"Tell him that we have detected a little suppuff in the nose and mouth of the deceased, and the measurement of suppuff used in general drugs will not be very large, and it is generally used for pain relief and inflammation, and a large number of saxfin purchases need to be filed with the Public Security Bureau."

"Seven fors? Why didn't the dossier from a few years ago mention this," Ning Hui said as he listened to Naranno's words

"Please, most of the family members from a few years ago were deceased, and autopsy was not allowed, and then our technology was still very limited at that time, and it was difficult to find it without autopsy" Although he was separated by his mobile phone, Naranno's disgusted tone still made Ning Hui smile awkwardly

"Thank you Nuno, this is a breakthrough point," Yu Ya replied with a smile

"It's okay, I did an autopsy, basically there is no need for an autopsy, and it is basically concluded that the time of death is at three o'clock, but there is a very important point, the blood sample brought back from the scene has another person's DNA in addition to the deceased"

"Whose DNA?"

"I conducted a DNA comparison and found that the DNA of two people is very similar, Liu Tao and Liu Siqi, but Liu Tao has been in prison for eight years, and this Liu Siqi's household registration was eliminated three years ago, and the public security determined that he died, and I will bring you the photo information later."

"Okay, Ning Hui and I are waiting for you at the gate of Liyuan Community"

"Okay" Naranno hung up the phone, and then began to pack his things and prepare to leave for the Liyuan community
