Lin Chuan found several large boxes of Yu Lu's photos from Yu Guocheng. After using technology to enlarge and compare them one by one, he finally found a small white flower sewn on Shen Xia's sleeve in a photo of Yu Lu and Shen Xia..
Lin Chuan interrogated Shen Xia and restored the truth of the year. It turned out that when Shen Xia was raped by Qiao Dayong, Yu Lu was knocked unconscious by Qiao Dayong to save Shen Xia. Shen Dong, who had been following him, rushed out and knocked down Qiao Dayong, but was scavenged.Wang Tiejun witnessed it, and Shen Dong had no choice but to kill him in order to silence him. Yu Lu, who suddenly woke up, couldn't help but scream when she saw the murder. Shen Xia covered his mouth and nose to stop him, accidentally killing him by mistake.At this point, Lin Chuan finally solved the 12.6 case completely.
