A girl who has been engaged in arduous forensic work for 9 years. I have seen countless scenes of unnatural deaths. Such a bitter and tiring job, Wu Hui is happy in it, from the police road, Wu Feng is a firm dreamer. Today, Wu Feng has become the backbone of the Yangpu Criminal Science Institute.
At the end of 2020, the Wujiaochang police station asked for help, hoping to help an unclaimed woman who had passed away for many years to do an identification.
The deceased was admitted to the emergency department in the winter of 2016 and died a few days later due to systemic multi-organ failure, and because she was using a fake IDENTITY card at the time, the hospital has not been able to verify her true identity.
In the past four years, the hospital and the police station have not given up tracking her identity. In the winter of 2020, the police at the police station finally found a clue from the missing person information and contacted her family. What Wu Feng and his colleagues had to do was to compare the blood samples of their parents sent thousands of miles away with the remains of women in the hospital to confirm whether they were related.
Originally, the biological sample of the remains was tested at two points, which were inconsistent with the control parent sample. Although the other comparison data of the sample have reached the national standard, it is basically possible to determine the relationship between the deceased and his parents, but this 0.1% uncertainty still makes Wu Feng put a question mark in his heart. What if it wasn't?
In the eyes of forensic doctors, missing people are not cold four words, it is a family's search for the root, in order to ensure that there is no mistake, Wu Feng decided to conduct another comparative examination with experimental data through hand calculation.
Along with her was Jin Yi, a forensic doctor in the same office. The two female forensic doctors showed their academic qualities, and their hand calculations were equivalent to 60 four-digit mixed operations. Such a test, the machine can get the result in 2 seconds. Counting by hand, the biggest challenge for them is not speed, but accuracy, and every step cannot be wrong. This is not just a calculation, but it will affect whether a long-lost family that has been separated by life and death can be truly reunited.
Using work breaks and rest time, for two days and one night, they carefully checked the formula for each step and finally calculated the result. Both the calculation and the hand calculation show that the remains did have genetic mutations at two points, and the identity of the deceased was 100% confirmed. The unidentified, foreign woman who died in Shanghai due to a sudden illness finally returned to her roots four years later and returned to her hometown.
