Episode 11
Qin Chuan was about to report to the Xucheng Criminal Investigation Detachment, and he came specially to say goodbye to Hu Bing.Hu Bing patted him on the shoulder and told him to do a good job.The two played with snowballs, as if they had returned to their carefree childhood.Qin Chuan and Xiao Qingdong will both go to Xucheng. They live in the same compound as Cao Zhongshu, and Qin Chuan's new neighbor is Li Wen.On the day of moving, both Li Wen and Xiao Qingdong came to help. Ye Haiping was even more excited because she could play with He Qinglian's children every day.
At this moment, Dong Zhenfa, director of the Dongping County Public Security Bureau, came here and asked Qin Chuan to help solve an unsolved case five years ago.Ding Li's mother and daughter were killed. The police suspected Gao Peng was responsible, but there was no conclusive evidence.The families of both parties went to the public security bureau every day to cause trouble. Dong Zhenfa had no choice but to come to Qin Chuan for help.Qin Chuan immediately went to Dongping County with Xiao Qingdong without saying a word.
Dong Zhenfa took them to Ding Li's house and described the progress of the case in detail.Qin Chuan carefully analyzed all the evidence and concluded that this was a murder of passion.However, Captain Zhou Yong reminded him to be careful in characterizing the case, because many experts had been invited to the case, but they were unable to make a correct judgment.Qin Chuan did not give up. He insisted on his inference and discovered a bloody fingerprint collected by the police.Unfortunately, this fingerprint has never been identified.
Qin Chuan was very dissatisfied with this and took all the evidence and files back to Xucheng.He originally wanted to ask Cao Zhongshu for help, but Wei Ning advised him not to meddle in his own business.Qin Chuan was unwilling to give in, and decided to continue investigating the case.With the help of Cao Zhongshu, they finally used the image analysis system to find the distinctive features of blood fingerprints, ruling out Gao Peng's suspicion.
Next, Qin Chuan and Xiao Qingdong began to investigate separately.They discovered that Ding Li and Zu Yang were closely related, so they immediately extracted Zu Yang's fingerprints.After comparison, Zu Yang was the most suspicious.In order to be sure, Qin Chuan personally went to Zu Yang to collect fingerprints and left his DNA sample.In the end, they successfully identified Zu Yang as the real culprit.
However, Qin Chuan was not satisfied.He felt that fingerprints and DNA alone were not enough to convict, so he asked Zhou Yong to find Zu Yang's wife to identify the bloody T-shirt at the scene.Zu Yang’s wife confirmed that the dress belonged to Zu Yang.At this point, Qin Chuan finally breathed a sigh of relief, knowing that this unsolved case would finally be solved.
