The case of the late Son Jung Min (22), a medical student who was found dead six days after he went missing at Han River Park, is falling deeper into a mystery as more questions arise.

Currently, attention is being gathered to Song Jung Min's friend, who is suspected of being with the medical student during the time of his disappearance. The friend who was with the deceased at that time claimed that he had thrown away the shoes he was wearing on the day of Son Jung Min's disappearance. Since then, Son Jung Min's father has been expressing his suspicions and doubts about the friend's remarks related to Son Jung Min's death.

CBS Radio 'Kim Hyun Jung's News Show' interviewed reporter Kim Seung Mo, a member of a news media's in-depth coverage team on the incident. During the interview, the reporter revealed some details.

Reporter Kim explained that there were three men recorded in the surveillance camera near the area of Son Jung Min's disappearance. However, these three men were not the individuals who were questioned as witnesses. Reporter Kim explained, "They are different from the three witnesses who claimed that they saw the two men (Son Jung Min and his friend) until 3:40 AM. The three men on the surveillance footage have yet to be identified."

The witnesses appeared not to know one another, but all three made a common statement claiming that they had not seen the two young men after 3:40 AM.

The late Son Jung Min's father has various unsolved questions about his son's friend regarding this case.

According to reporter Kim Seung Mo, the bereaved family presented three main questions: #1 Why didn't the friend call Son Jung Min's family despite the family looking for his friend for over an hour? #2 Why did Son Jung Min's friend talk with his mother at 3:30 AM? This was confirmed by the police when they checked the friend's call logs.

Lastly, the most questionable part is that Son Jung Min's friend had discarded the shoes he was wearing on the day of Son Jung Min's disappearance.

Since then, more netizens have become suspicious of the late Son Jung Min's friend, who witnesses say was the only person with the medical student at the time of his disappearance. In particular, many netizens find it very suspicious that the friend had thrown away his shoes.

Netizens have been in fervent discussion as they commented, "We're not being suspicious of the friend for no reason, there are so many things that he did that is suspicious," "I hope they find even a small piece of evidence against that friend so that the police can investigate him officially," "There are so many things that we don't understand about this friend's actions. For instance, your friend disappeared but then you throw away your shoes because it was dirty? The friend called his mom at 3 in the morning to tell her he's looking for his friend if it was serious to call his mom why didn't he call his friend's parents? And if it was such a dire situation, why didn't he call the police right away?" "There is surveillance footage of the friend hastily leaving the scene of Son Jung Min's disappearance," and "There is definitely something fishy about this guy."
