There are a series of face recognition information in the network of public security organs. When these criminals are identified in face recognition, they will definitely be given a series of alarm processing. Even if the fugitive gains 50 pounds in nine years, it won't change his face, or even some features of his face.
So it will still be found by face recognition, which is also attributed to the progress of our technology. Our current legal system is so strict that even if we flee to the ends of the earth, we will still be arrested and brought to justice. These are the reasons why fugitives who have gained 50 pounds in 9 years will be found by face recognition.
