When Du Dayong saw that everyone under him was staring at the big whiteboard, he asked Ning Hewei to post the photos one by one.

It was not until Ning Hewei posted all the photos that all the team members surrounded the big whiteboard.

Du Dayong picked up a short wooden stick and began to point to the photos to introduce them one by one.

"This is a case of sexual assault and intentional homicide in Zhengjiazhuang, Dongjiao City in March this year."

"The deceased is Fang Xiujuan, 19 years old. After preliminary investigation, the Dongjiao Municipal Bureau found that Fang Xiujuan's registered residence is from Dongluliao City. She has been working in Dongjiao City for 2000 and worked as a waiter in Chunfeng Restaurant. Until she was killed, she still worked in this restaurant."

"The deceased is 160 cm tall, weighs 49 kilograms, and has a good appearance. According to colleagues in the restaurant, Fang Xiujuan is a relatively honest girl. She has never talked about her boyfriend, nor has she found any contact with the opposite sex outside. She has always been a very hardworking and diligent girl in her restaurant work."

"On the morning of March 13, 2002, Fang Xiujuan, who had not returned to work in the restaurant for two days of leave, attracted the attention of her boss Liu Zongxiang, so she asked her husband Song Chunfeng to go to Fang Xiujuan's residence to check."

"Song Chunfeng arrived at the deceased's residence at 10:40 am on the 13th. After knocking on the door many times but failed, he found the landlord and opened the door. After entering the room, he opened the barrier curtain in the room and found that the deceased was lying on the bed covered with a quilt. Song Chunfeng went forward to call, but when he approached, he found that the deceased's face was indigo blue. He then touched the deceased's neck. Then he found that the deceased was dead. He immediately called 110 to call the police."

Speaking of this, Du Dayong stopped for a while and asked the team members to digest what they just said.

After pausing for a while, he pointed at the photo with a wooden stick again.

"Let's look at the photos on the scene again. The deceased lived in a single room. The entire single room was less than 18 square meters, and there was only a four-square-meter bathroom. The remaining location allowed the deceased to divide it into two with a partition curtain in the middle of the room. The furnishings in the whole room were relatively simple."

"It can be seen from the photos that the deceased had only a simple wardrobe, a bed, a bedside table, a desk, a wooden backrest chair and two simple plastic stools in the room."

"Now let's look at the situation outside the house. The deceased's house is a roadside house, with only a wooden door and an iron fence gate. The deceased lives in the outermost house at the east end. There is a path on the right side of the door, and there is a rental house on the left side of the door, but it is currently uninhabited."

"After the inspection by the technical investigator of Dongjiao Municipal Bureau, the scene was cleaned, and no fresh fingerprints were found except for the deceased and Song Chunfeng. Except for the footprints of the deceased and Song Chunfeng and the landlord, only one footprint found at the bend of the entrance is consistent with half of the footprints found on the inside of the on-site bed, and the footprints are in fresh state."

"The technical investigator compared all the shoes in the deceased's room, but found no shoes that matched the footprints left on the scene, and the sizes were not correct. The deceased's shoe size was 36 sizes, and half of the footprints on the scene and the footprints left outside the house were 40 sizes."

"Then the technical investigator conducted a large-scale inspection around the scene, and obtained six footprints of the same type, and then the footprints disappeared on the main road. According to the simulation analysis of footprints, the male suspect, weighed in the range of 55-60 kg, and should be between 155-170 cm. The age should be between 18-45 years old."

"The body was inspected twice by the forensic doctor. The initial inspection report said that the deceased had been sexually assaulted before his death. After the forensic doctor, the deceased found a sharp weapon on the neck of the deceased. Therefore, it was judged that the deceased should have had sexual assault after being coerced by the suspect, but no dandruff was found in the deceased's nails."

"In addition, after the forensic doctor dissection of the deceased, he found through the contents of the stomach that the deceased should have died between 1:00 a.m. and 2:00 a.m. on the 11th. A large amount of sperm spots were found inside the deceased's body and had been sent to Qinglu Municipal Bureau for DNA testing and comparison and retention."

"The deceased had sex after a second forensic investigation. However, no deceased had sex at the scene. It was suspected that the suspect was forced to use towels or other clothes and toilet paper to plaster the deceased's private parts, and was finally taken away from the scene by the suspect."

"Let's look back at the photos on the scene. The suspect has not carefully cleaned the scene, but can also be judged to have it carefully cleaned it. Therefore, from the photos, we can see that the scene is very neat and not messy."

"After seeing the photos on the scene, let's look at the cause of death of the deceased. After forensic identification, the cause of death was mechanically asphyxiated. The forensic doctor judged that the deceased should have died by the suspect's neck with his hands."

"So according to the forensic identification, it can be judged that the deceased must have had resistance at that time, but no dandruff or hair was found in the nails and on the bed of the deceased. So I think the deceased should have put on clothes and gloves after the sexual assault was over. However, why did the killer suddenly occur at that time? Further investigation is needed. There is another situation that can be guessed that the suspect's hair may be very short."

Du Da explained the general situation in one breath.

"You can now observe the photos first, and combine the inspection report of the technical investigator and the forensic investigation report to conduct case analysis. I did not take the case analysis of the case of the Criminal Police Brigade of Dongjiao Municipal Bureau. This is what I hope we can draw some conclusions and inferences to see if we can have any new discoveries and ideas based on them."

"At the same time, I want to tell you that Zhengjiazhuang where the deceased lives is a place at the junction of urban and rural areas. There are more than 400 rental houses in such a row, and there are also rental houses in the main house. There are nearly 3,000 foreign populations, and more than 1,200 local population, and there are nearly 800 men who meet the characteristics of the suspects alone."

"And in the past two months, the Dongjiao police have checked all adult men in Zhengjiazhuang, but none of them have compared them."

"At present, Dongjiao police have expanded the scope of investigation and conducted further investigation and comparison."

"Not only that, except for the traffic monitoring in and out of the main road of Zhengjiazhuang, there is no other monitoring."
