["DNA knows the murderer" - Gyeongbuk food bar murder case] In July 2008, an urgent call was made to 112. A woman was stabbed to death by a weapon in a small food stall in North Gyeongsang Province! The victim was a landlady in her 50s who ran a food stall, and the condition of her body was also very horrific... Who was the culprit who brutally murdered the hostess at dawn when people were rare? Since it is a restaurant where an unspecified number of people come and go, a total of 136 pieces of DNA were collected at the site. Among them, bloodstains from a broken beer bottle, which appears to be a tool for the crime, were also obtained as a suspect. The detective in charge immediately conducted a DNA comparison on the regular customers, but the investigation was at a standstill for a month. It was because the DNA of all the suspects did not match... In the process of identifying the suspects from the beginning, the investigators used Y-STR analysis and the SCAS crime analysis program. And finally, after a month of the incident, the truth began to be revealed. What is the truth of that day?
