Gao Delong's son Gao Yitong said that he and Chen Jiaorui are in love with each other, the other party loves him very much, and he can't live without her. As for the death of the Chen family's parents, Gao Yiyi seemed very satisfied, because then he and Chen Jiaorui could be together. He admitted that he was used to sleeping with headphones on, so he didn't hear anything on the night of the crime.
Channing found Gao Tong's fingerprints on the golf club, but according to his recollection, the last time he picked up this club was a month ago. That night, he secretly went to the terrace to find Chen Jiaorui, so that rose rose in the Chen family. The two of them would meet in private like this before, but Chen Jiaorui was a little unusual that day and had an argument with him. It is precisely because of this that their affairs will be discovered by the Chen family's parents, and Chen Xinghai will kick him out of the house.
Chen Jiaorui said that she and Gao are not in love with each other as he said, but everything is just his wishful thinking, and he has been pestering him. He always said that the adoptive parents were bad, so Chen Jiaorui didn't like him. Moreover, in Chen Jiaorui's eyes, Gao Tong was very ruthless, and she was quite afraid of him. As for the relationship with her adoptive parents, Chen Jiaorui said that they have a good relationship. Xia Ying felt a little strange, someone must be lying. She suddenly thought that she saw the series of footprints at Chen's house, and according to Chen Jiaorui herself, she was chasing the murderer from the second floor to the yard with bare feet.
Xia Ying observed Chen Jiaorui's feet and asked her to walk and run normally on the red mud. After careful study and judgment, Xia Ying came to the conclusion that Chen Jiaorui's footprints appeared first, and the vase was broken later. And her pace is not in line with the situation of chasing the murderer, but more like a leisurely walk. Li Xuekai also got clues and found that the wound on Chen Jiaorui's neck was not like the one she said was stabbed while lying down, but was scratched while sitting.
Hu Qian investigated that Chen Jiaorui had frequent calls with a person named Liu Zhizhi in the past six months. At 10:46 that night, Chen Jiaorui and Liu Zhizhi talked for five seconds. Then after Chen Jiaorui called the police and before the police arrived at the scene, Liu Zhizhi and Chen Jiaorui had another eight-second phone call. Until Chen Jiaorui was admitted to the hospital, their phone call never reappeared.
Liu Zhizhi said that she had a sleep disorder, and she and Chen Jiaorui met in the hospital, and they all talked about seeing a doctor on the phone. Police found a bloody sweater at Liu Zhizhi's home. After inspection, Liu Zhizhi's DNA was found on the glass fragments at the scene, Liu Zhizhi's vomit was in the trunk, and the blood on the sweater belonged to Chen Xinghai and Chen Jiaorui. Faced with solid evidence, Liu Zhizhi confessed.
In front of the evidence, Chen Jiaorui wanted to lie, but it was full of loopholes. She didn't tell the truth until the police came up with enough evidence to convict her. That night, after Chen Jiaorui answered Liu Zhizhi's call, she went to the adoptive parents' room. Before they were prepared, Chen Jiaorui quietly took Liu Zhizhi into the house. Because he hid in the trunk for a long time, Liu Zhizhi vomited in the back of the car. After that, the two worked together to kill their adoptive parents, and Chen Jiaorui also pretended to be a victim and directed and acted in the play.
As for the reason, Chen Jiaorui said that although her adoptive parents adopted her, they never loved her. When she was a child, her adoptive parents left her abroad. When she finally got used to it, they wanted to discipline herself. As long as she was disobedient, they would say she was crazy and sent herself to a mental hospital. As for Gao Tong, it was just her entertainment.
