Why is the silver case the top bag?

The silver box is not the top package.

Many netizens think that the murderer of the serial murder of Baiyin in Gansu is probably someone else, but those who know how to solve the case of Baiyin should know that DNA can't deceive people. According to the police report, it is based on DNA-Y comparison technology that the killer can be determined to be tall.

At that time, the police compared the DNA of a detained Gao surnamed person with the suspect and found that they were very similar, so they gradually followed the trail and set their sights on Gao's distant nephew, who was later captured, before they could solve the case.

Y-STR method:

Y-STR method is a DNA detection method of sperm in forensic medicine. All male individuals of the same paternal line-brothers, fathers and sons, uncles, cousins and grandparents-have homologous Y chromosomes. My uncle's DNA was entered into the database because of bribery. The police compared it with the traces left by the murder scene in that year, and finally found that the members of the Gaos were highly consistent.

The leap of investigation technology finally brought this murderous maniac who killed 1 1 lives to justice. With the progress of society, the application of high technology in investigation and evidence collection has greatly improved the investigation ability of public security organs. However, in addition to the power of technical contribution, the unremitting efforts of case handlers for many years cannot be ignored. It is understood that in order to catch the murderer, the Baiyin Public Security Bureau has compared at least 654.38+10,000 fingerprints over the years.
