Leng Xiaobing and Chen Han came to Zhou Xiaoyun's house to learn about the situation. They found that Zhou Xiaoyun was completely insane, extremely sensitive to Shen Yu's name, and exhibited extremely strong mood swings. According to Zhou's mother, Shen Yu is thoughtful and delicate, and she is perfect in dealing with people and things. His daughter Zhou Xiaoyun has a close relationship with her, but since that happened, the whole person's temperament has changed drastically.
Chen Han really couldn't figure out why if the murderer killed Shen Haiyang, why would he need to protect Shen Yu everywhere and remove all obstacles for her. Leng Xiaobing used the mud man as a metaphor, thinking that the murderer had been hiding behind Shen Yu, but in fact he wanted to gradually shape and change Shen Yu's thought through these methods of injury, and use extreme means to solve everything he encountered.
Old Gu found many photos in He Weiguang's house, and judged that the murderer was proficient in photography, and he had to have the conditions to develop the photos. It just so happened that He Weiguang didn't possess both of these points. Leng Xiaobing inspected the different thicknesses of the photos, focusing on the photo studios along the 300 bus from 1991 to 2000.
At the same time, Mr. Natsuki Analyzed that he should have been to the photo studio before his death, so he searched for the relics and found a receipt from the "Red Light Photo Studio". Through the receipt address, Xia Mu found the residence of Tan Jinsong, the owner of the photo studio. However, this person died of illness as early as last year. Only his son Xiao Tan was in charge of the grocery store.
At first, Xiao Tan had a very bad attitude towards Xia Mu, but when he found out that the other party was a policeman, he immediately turned into a smiling face and led him to an old photo studio that had been closed for many years. Unexpectedly, as soon as he arrived at the door, he encountered Leng Xiaobing and the police from the police station. Xia Mu hid after seeing this, so Xiao Tan had to take them in first.
Leng Xiaobing described to Xiao Tan a suspect with a height of 1.8 meters and a lonely personality. Because the time was too long, Xiao Tan couldn't remember it. He vaguely remembered that his father had taken many photos, and no one came to take it later. Among a pile of old photos, Leng Xiaobing found that all the dead in the Haizhou case were gathered inside, and immediately realized that the murderer was most likely to have worked here.
Xiao Tan followed the police back to assist in the investigation. Xia Mu, who was hiding next to him, handed the receipt to Leng Xiaobing. Afterwards, he went to the library and happened to meet Shen Yu. Shen Yu greeted Dean Huang, looked up the books donated by his father in the library, and quickly noticed Hu Shanquan’s name on the library card. He couldn’t help recalling that his father was very taboo about this person and told her not to mention it again. .
On the other hand, Xia Mu has been with Shen Yu all day, saying that both of them have the same experience, both have experienced the pain of the murder of their relatives, and they are consistent in tracing the murderer, and they should work together. However, Shen Yu did not respond. Xia Mu knew that she wanted to seek revenge from the murderer alone, and persuaded her not to do stupid things.
On the other side, Xiao Tan carefully recalled the suspicious people in the photo studio, and suddenly thought of a kid surnamed Hu. He was an orphan at the time and usually lived in the utility room behind the photo studio until one year when his father saw him. Very poor, he called him to the house for New Year's Eve dinner. Although the camera has the function of time-lapse photography, the man insisted on taking pictures of everyone. According to Xiao Tan's description, Leng Xiaobing seemed to see the murderer right in front of him.
Shen Yu guessed that this matter had a lot to do with Hu Shanquan, and she also took the initiative to contact Zhang Shu and Aunt Zhang to meet, both of whom are veterans of Anding Hospital, so asked them about this person. Through understanding, Shen Yu learned that Hu Shanquan was once Shen Haiyang’s best friend and a patient in the hospital. Because of his excellent photography skills, he was well received by everyone. He also took a group photo for all the staff.
