However, I quickly changed my mind and devoted myself to analysis for two weeks, using all the techniques I had acquired. First, he used a 3D distortion correction technique to correct the position values in the video. Next, the keypad of the same model as the iPhone used by the leader was extracted and added to the video. At the same time, it is said that the keypad area was restored to be faint after undergoing work to improve image quality. The password read in that way is a whopping 22 digits long. When I sent the analysis report to the investigator, the numbers matched. Inspector Shim said, “I wondered if this would happen, but I was dumbfounded.”

Afterwards, the investigation proceeded smoothly. Evidence of the crime poured out from the leader’s iPhone, and it played a decisive role in arresting other gang members. Based on this, the North Chungcheong Police Agency’s drug investigation unit detained and sent 9 people, including 6 members of the group including the general manager, and 3 habitual drug users, and sent 25 drug users without detention. The group was found to have smuggled drugs, such as Philopon and Ketamine, into cosmetic containers for about eight months starting in August 2023 from overseas. The market value of the confiscated drugs reached 1.45 billion won.
Inspector Shim, now 48 years old, does not hesitate to read at night to learn about the ever-advancing science and technology. He entered the Department of Forensic Science at Chungnam National University and received a master’s degree on the topic of ‘Integrity of Digital Video Evidence’ in 2022. Inspector Shim said, “Looking back at the past, there were many incidents that left me with regret and thought, ‘If only I had a little more skill, I could have caught the criminal.’” He added, “I also want to pursue a doctoral degree in the future.”
