Episode 10

Liu Yuanyuan and Ding Youmei looked almost exactly the same. Zhu Qingyue suspected that Liu Yuanyuan took the exam for Ding Youmei.Judging from the school's surveillance, Liu Yuanyuan left fifteen minutes after entering Gao Huilan's laboratory. She deliberately covered her face when leaving and had a plastic bag in her hand.Wan Guoxin found Gao Huilan's remittance records to Liu Yuanyuan. Because the passbook was registered in her mother's name, it had not been found before. The earliest one was eleven years ago, and Liu Yuanyuan's college entrance examination and Ding Youmei's TOEFL exam were at the same time. In addition, Gao Huilan also sent a large sum of money to Luan Fang, a classmate in the same examination room as Ding Youmei.

Ding Youmei admitted that Liu Yuanyuan took the exam for her and said it was all arranged by Gao Huilan.Gao Huilan said that she performed a free operation on Liu Yuanyuan's mother, but Liu Yuanyuan kept threatening her with taking a substitute exam. After her mother died, Liu Yuanyuan came to the laboratory to find her, and the two had a quarrel.Liu Yuanyuan took a knife to kill Gao Huilan. Ding Youmei heard this and pulled away from Liu Yuanyuan. Liu Yuanyuan broke down and cried. Gao Huilan comforted Liu Yuanyuan for a while, and then Liu Yuanyuan left on her own.Zhu Qingyue showed Ding Youmei the surveillance photos, and Ding Youmei said it was Liu Yuanyuan without thinking.

There is currently no evidence that Liu Yuanyuan's death is related to Gao Huilan Ding Yumei. Liu Yuanyuan left the building and left the school. The video was very blurry and it was not clear who it was.Han Feng boldly speculated that if Ding Youmei pretended to be Liu Yuanyuan and left the building and lost her head, and then returned to the experimental building through the iron fence, she could avoid the surveillance at the school gate and return to the school. However, it is still unclear how she avoided the surveillance in the building.

Qi Sizhe found a little fiber and human tissue in the cracks of the bulk freezer in the specimen room, which were not bulk specimens.When discussing the case, Qi Sizhe told Han Feng and Zhu Qingyue that generally when schools need to use cadavers, they will hold classes in the anatomy room and will not move the cadavers around. Moreover, the cadavers are packed in body bags when transporting them, which is the best cover.Gao Yuan tested the fibers and human tissue and found that the fibers came from Liu Yuanyuan's coat, and the human tissue belonged to Ding Youmei, indicating that Ding Youmei wore Liu Yuanyuan's coat. Gao Huilan was lying, and Liu Yuanyuan did not walk out of her laboratory alive at all.

The police went to extract Ding Youmei's blood for comparison. Qi Sizhe and the others went to inspect Gao Huilan's laboratory, which contained a large amount of Liu Yuanyuan's blood. In the corpse cabinet, Ding Youmei's DNA was found, and Gao Huilan admitted that she had done everything.That year, when Gao Huilan saw Liu Yuanyuan for the first time in the hospital, she thought it was her daughter Ding Youmei.Ding Youmei's academic performance was very poor, and her father was very dissatisfied. Gao Huilan approached Liu Yuanyuan and offered to take the exam for her mother in exchange for surgery.

Gao Huilan thought Liu Yuanyuan was a good child. When she learned that her mother's illness had recurred, she went to Liu Yuanyuan's mother and bluntly stated that she was Liu Yuanyuan's burden and a bottomless pit. Originally, Liu Yuanyuan could have been admitted to a medical university and live a better life, but now she has been dragging her down and has to pay off the huge debt she owed.Liu Yuanyuan's mother was ill. She grabbed Gao Huilan's clothes and pointed at the medicine on the cabinet. Gao Huilan threw the medicine away and watched her move little by little.Later, Liu Yuanyuan came to Gao Huilan and took out the buttons that her mother had torn off Gao Huilan. Gao Huilan was dumbfounded when she saw it, so Liu Yuanyuan stabbed Ding Youmei with a knife. Gao Huilan picked up a hammer and knocked Liu Yuanyuan. After that, Gao Huilan asked Ding Youmei to put on Liu Yuanyuan's clothes.

There are fingerprints of Liu Yuanyuan's mother, Liu Yuanyuan and Gao Huilan on the button.Zhu Qingyue told Ding Youmei that Gao Huilan had confessed everything and admitted to killing Liu Yuanyuan. Ding Youmei cried and asked what would happen to her mother. Zhu Qingyue said that Gao Huilan would be handed over to the judiciary for prosecution for intentional homicide. Ding Youmei blamed herself after hearing this. It was all her fault. Zhu Qingyue told her that she was suspected of harboring but would be sentenced, and then left the interrogation room. Ding Youmei actually cried and laughed after Zhu Qingyue went out.
