218 Speculation
There was nothing suspicious in the surveillance footage.
Shen Yin looked at the surveillance videos near the crime scene a few times, but she still could not find anything.
Actually, it was not completely accurate to say that it was nearby. The surveillance cameras were a certain distance away from the crime scene. It was easy for the murderer to avoid the surveillance cameras after committing the crime. Furthermore, he seemed to know the range of each surveillance camera very well.
Meng Heng poured a cup of hot water and placed it on her table. He asked, “How is it? Why don’t you take a break and look for other clues?”
“I’ll watch it one last time.” Shen Yin did not want to give up so easily. After taking a sip from the glass of water, she continued to watch the black and white video repeatedly.
It was almost time for a lunch break. Wu Zheng put down the documents in his hand and walked behind Shen Yin to persuade her. “Go eat something first. If we really can’t find any worthwhile in the surveillance footage, we’ll think of something else.”
“I have a question.” Shen Yin stared at the image on the computer screen and frowned in confusion.
“What is it?” Wu Zheng put his hand on the back of the chair, bent down, and stared at the screen seriously.
“Why does he know the location of every surveillance camera so well? To be fair, even I might not know the location of every surveillance camera near my house.” She frowned as a ridiculous thought lingered in her heart.
“We can’t rule out the possibility that the culprit scouted ahead.” Although Wu Zheng said that, a thought was growing in his mind. He could not help but mutter, “Actually, the people who know the location of the public surveillance cameras in Chengxi are the people in charge of installing the surveillance cameras.”
Shen Yin looked around. Meng Heng had already gone to the canteen to eat, and Zou Sheng had not returned the entire morning. Now, only Wu Zheng and her were left in the office. However, she still carefully got up and closed the door before walking back and staring at Wu Zheng seriously. “You’ve considered this possibility too, right?”
“If it’s really an inside job, that explains our failure last night.” Wu Zheng lowered his voice. He could not help calculating the probability that this was true.
Shen Yin pursed her lips tightly and suddenly asked, “Were the SWAT officers involved in the operation last night seconded from Chengxi?”
“That’s right.” Wu Zheng’s pupils dilated. His face showed his shock. He could not help but say, “Could that be the reason for the leak? Could there be a mole be in the Chengxi Branch?”
“We can’t rule out this possibility.” Shen Yin shifted her gaze to the surveillance video again.
She had been in this line for so many years and had participated in countless cases. She had always firmly believed in the principle that there was no perfect crime in the world. As long as it was committed, there would be a clue somewhere.
However, the serial murder cases were too clean, and the murderer knew how to avoid the surveillance cameras. This made her suspect that the source of their trouble was internal.
Wu Zheng patted Shen Yin’s shoulder, indicating that she should not mention this matter to anyone, not even Zou Sheng and Meng Heng.
If Shen Yin’s guess was right, this would implicate her colleagues in the public security system. Then, they would have to face an enemy who was definitely well hidden.
If word of this got out, no one could guarantee what the consequences would be.
Shen Yin understood this logic and nodded in agreement. “I know what to do. Besides, at the moment, this is only a guess. Moreover, the DNA I’ve collected shows that th perpetrator isn’t in our police department’s internal database. Now we lack supporting evidence, so we need to approach this from another angle.”
Wu Zheng agreed. The two of them went to the cafeteria to eat with heavy hearts. Just as they finished getting lunch and found an empty seat, they met Zou Sheng, who was late.
The moment he entered the cafeteria, he pounced on the auntie like a hungry wolf. “Hurry up and get me more food. I’m so hungry!”
The canteen auntie smiled and scooped a plate of red braised pork for him. She also gave him two portions of rice. She could not help but tease, “Little Zou, what case have you been busy with recently? Why are you so busy? Why are you only eating now? Your captain and the beautiful new forensic pathologist have just arrived.”
“Our team only works on big cases.” Zou Sheng was tight-lipped. After a few perfunctory words, he took his lunch and looked around the canteen.
Zou Sheng’s eyes lit up when he saw Shen Yin sitting in a corner. He leaned over with a smile and said, “Thank you, Sister. If you hadn’t helped me today, I would have died.”
“Don’t talk nonsense and pretend to be pitiful. Little Meng has also been busy, but I haven’t heard him complain about being tired.” Wu Zheng reprimanded him with chopsticks still in hand.
Zou Sheng immediately pouted. After looking around, he asked pitifully, “Where’s Little Meng? Why isn’t he here for lunch?”
“Little Meng finished eating long ago.” The canteen auntie sat next to them with a benevolent look on her face. She held a plate of food in her hand and asked with a smile, “What have you been busy with recently? I saw Little Meng’s worried expression. Young people these days are so listless!”
