Ran Xiaoke took Zhao Yixin to He Yuanyuan's residence, Ran Xiaoke asked Zhao Yixin to start filming the whole process from the time he entered the door, Ran Xiaoke carefully took the oil painting off the wall, looked through it, and found that there was a small hole in the back, slowly tilted the oil painting, a silver metal U disk was half exposed, Ran Xiaoke carefully took out the U disk, put it in a plastic bag for evidence and sealed it.

At this time, the phone rang, and it was a call from the on-site investigation. "Detective Ran, the DNA is compared, and the organs in the 4 glass bottles are from the victims of the 4 cases."

"Thank you!"

The key evidence was found, indeed from 4 cases, and He Yuanyuan's phone recordings recorded both his admission to his crimes, and his later confessions, of course, the first time the phone recording on the rooftop of the Skyline Tower was more credible. If the USB flash drive in the oil painting is really as He Yuan said, and the case is recorded in it, then the case will be solved.

Ran Xiaoke couldn't wait for a moment, called Zhao Yixin to rush downstairs, drove back to the office of the Criminal Investigation Bureau, turned on the computer, plugged in the USB flash drive, and sure enough, there were several videos. Zhao Yixin was beside him and couldn't wait to uncover the mystery.

The picture is clear and clear, the whole case is recorded quite completely, sharp dagger ...... Tattoo on the left arm of the truck driver....... Lao Du's left ear...... Crazy high beams on the highway....... Wait a minute......

Ran Xiaoke thought to himself, it was time to report the overall situation of the case to Director Liu. I dialed Director Liu's phone.

"Director Liu, the case has been solved, the suspect He Yuanyuan, the evidence is complete, the only regret is that the suspect has ......passed away," Ran Xiaoke reported to Deputy Director Liu.

Director Liu is Ran Xiaoke's mentor, and he has the grace of knowing him, Director Liu was promoted from the post of director of the police station, and Ran Xiaoke was his subordinate in the police station, and it was precisely because of Deputy Director Liu's understanding of him that he had the opportunity to be transferred to the Criminal Investigation Bureau. Director Liu is very clear about Ran Xiaoke's style, as long as the task is assigned, he will definitely give you the most beautiful results, with such subordinates, when the leader is relaxed and happy, and for the leader who has such a result, regardless of the process, gives his subordinates the greatest subjective initiative, compared to those leaders who have to give orders in any link, such a leader as Director Liu gives his subordinates the best opportunity to display and the best exercise.

"It's good that the case is solved, it's normal to be a little regretful, at least no one will be killed again. Xiao Ran, it's not easy, such a tricky case has been cracked in such a short time, and I want to fight for your meritorious service to the higher authorities", Director Liu was very happy.

"Thank you, Administrator, it's all my business."

Director Liu hung up the phone.

Director Liu likes Ran Xiaoke's capable, modest and low-key subordinates, in his opinion, among the young people now, there are fewer mature and humble people like Ran Xiaoke, and in him, Director Liu saw the shadow of his youth. He admired Ran Xiaoke very much, and he took him as a key training object when he was at the police station.

To some extent, Ran Xiaoke is his descendant.

Ran Xiaoke hung up the phone and looked at Zhao Yixin, his eyes were full of affirmation, and Zhao Yixin's eyes were full of admiration.

Zhao Yixin didn't expect that the three-day deadline to solve the case military order really completed the task successfully, this is his first big case in the true sense, which was completed with his master Ran Xiaoke, Zhao Yixin is really full of pride in his heart, and he also feels deeply lucky to have such a persevering and courageous master.
