On September 2, Wang Damin was the first person to escape from Yanshou County Detention Center, 53 seconds earlier than Li. Before escaping from the detention center, they killed Duan Baoren, a policeman who was about to retire, in the duty room.
When Gao Yulun was talking to Duan Baoren in the duty room, he caught him by surprise and strangled him from behind. While Duan Baoren was struggling, Wang Damin and Li Jianwei rushed into the duty room to help. A few minutes later, Duan Baoren stopped breathing. Gao Yulun then found the key and opened the anklet. He changed into a light blue long-sleeved police lining, with dark pants and dark shoes. Wang Damin and Li Jianwei, who also changed their police uniforms, walked out of the gate of the detention center.
The whole escape took about 23 minutes, without a hammer or digging a hole, let alone climbing a trench. From the prison area to the gate, Gao Yulun was a little surprised. They looked around the gate of the detention center for a while, then strode out until they heard the warning sound of the sentry outside and began to run away quickly.
Two days later, the wanted order printed with photos of three people's prison uniforms and identity information was almost posted all over Yanshou County, and roadside stone pillars, telephone poles and canteen glass windows could be seen everywhere. The police advocate citizens to provide valuable clues or help catch fugitives, and the maximum reward can reach 1.5 million yuan. Wang Baoshan, director of xinglong village Village Committee in Qingchuan Township, Yanshou County, received a notice from the township government and sent people to defend along the cornfield in the village, because the villagers in the neighboring village found Gao Yulun while herding cattle and reported it in time.

More than 200 acres of cornfields, armed police drove five big trucks, and stood five meters around the cornfields along the way. Two hours later, Gao Yulun was arrested while fleeing to his relative Tu Jianguo's house.
