This case has been satisfactorily solved. Unfortunately, Li, a female college student who lost contact in Nanjing, has been killed. Her boyfriend and others tricked Li to the border of Yunnan and killed her in cold blood. According to the notice issued by Menghai County Public Security Bureau in Xishuangbanna, they have successfully cracked the case after police investigation and search. After preliminary investigation, her boyfriend Hongmou and Zhang Moguang and Cao Mouqing lured Li to the suburban forest of Menghai County.

It is reported that Li, a female college student who lost contact, was born in 1998. She is 22 years old. She is from Baoying, Jiangsu. She just graduated from the Cultural Tourism College of Jiangsu Vocational and Technical College of Economics and Trade. After graduating from college, Li moved in with her boyfriend Hongmou. According to Li's father, the reason why her daughter moved in with her boyfriend Hongmou was mainly to prepare for the next college entrance examination. After moving to a boyfriend, after this case, the boyfriend lied that his girlfriend Li had quarreled with him and went to Yunnan for a trip. After Li left, he couldn't contact his girlfriend and informed Li's father. Subsequently, Hong's father Li, who accompanied him, reported the case to the police station.

As for, why did Hongmou do this to his cohabiting girlfriend? The author believes that from the current situation, there may be two possibilities for Hongmou to kill his cohabiting girlfriend next time. 1 The possibility is that Li wants to break up with Hongmou, and Hongmou doesn't want to. Hongmou was psychologically unbalanced, so he killed his cohabiting girlfriend Li next time. Because, Li's best friend said in an interview that Li and her boyfriend Hongmou often quarrel. After a quarrel, he ran over to complain to Li. At this time, Hongmou followed, but at that time Hongmou did not coax Li, but his words were extreme. According to Xiao Xie, Hongmou made her unable to see through. Judging from Hong's words, he is a very conceited person.

Of course, there is another possibility in this case, that is, Li may have been silenced by Hongmou after discovering Hongmou's secret, because another friend of Li said in an interview that Hongmou was excellent at good times and extremely bad at bad times. This can't rule out that Li may have discovered Hongmou's secret, and if Li wants to keep his mouth shut, he can only be silent. It can be seen from the fact that Hongmou and two other people conspired to kill Li. If Li and Hongmou are just ordinary small contradictions, they will not be silent. From this perspective, it is not excluded that Li may be silent after learning the secret of Hong. Of course, these are only two possibilities, and the final result will not be completely solved until the case is thoroughly investigated.
