Chapter 76: Silence the Witness by Murder

Ryoko Oogawa didn't answer Jo Oogawa's question, but rather spoke on her own accord, "We investigated Yan Fei's online shopping records and found that he purchased a drone on the internet, yet no one has ever seen him use it. Shortly after he bought the drone, there were several incidents within a one-kilometer radius of Yan Fei's home, where drones used pea bullets to injure people. Later, we collected footage from surveillance cameras near Yan Fei's home through Igawa's household, which captured the drone involved in these incidents."
