Since the launch of the province's backlog of homicide cases, the Lanzhou Municipal Public Security Bureau has organized a special class to vigorously attack the stronghold, and the criminal technology department of the Municipal Public Security Bureau has detected the individual characteristics of suspicious persons on the key physical evidence of the scene that has been repeatedly sent for inspection countless times, the clues have gradually become clear, the case has made a major breakthrough, and after investigators have traveled to many provinces to investigate hard, in April 2021, the criminal suspects Wen XX and Dai XX have been arrested in Kunming and Lanzhou. The suspects had a strong sense of anti-investigation, evaded crimes and stubbornly resisted after arriving at the case, and confessed that the truth and falsehood were intertwined; the investigators did not discuss the case, but did not let go of doubts, dug deep and studied in depth, analyzed and studied in depth the key elements such as the suspects' means of committing crimes, characteristics, and so on, and believed that this group of criminal suspects in and around Lanzhou City might still commit the same type of cases, so they submitted them to the Provincial Public Security Department for coordination, submitted them to the Ministry of Public Security for supervision, and launched a series of similar cases and investigations to further expand the results of the battle.

On July 22, 2021, the "7.22" series of robbery and murder case special cases led by the Provincial Public Security Department, the chief investigator of the Lanzhou Municipal Public Security Organs, and the baiyin City Public Security Organs co-organized were immediately established and carried out special investigation work.
