[Asia Economy Reporter Han Seung-gon] "More than the contents of the cellphone, I was curious about 'why the cellphone was lying there.'"

Regarding the so-called 'Hangang university student drowning accident,' the late Son Jeong-min's father, Son Hyun, mentioned an expert analysis on his blog on the 12th, saying "The level is different" and "I don't know why I never met such a person," drawing attention to the expert analysis Son referred to.

The expert Son mentioned is Professor Oh Yoon-sung of the Department of Police Administration at Soonchunhyang University, who appeared on OBS's 'News Today' broadcast on the 9th. On that day, Professor Oh raised questions about the process by which a sanitation worker found the cellphone of Son Jeong-min's friend, A.

Professor Oh spoke about ① the timing of the sanitation worker's acquisition of the cellphone ② the possibility of others nearby acquiring the cellphone ③ securing other closed-circuit (CCTV) footage ④ whether the sanitation worker underwent a polygraph test.

He said, "At first, the sanitation worker did not specify the timing, but later said, 'I found it there at 9:30 a.m. on May 12,' but personally, I find that statement less credible," adding, "The place where the cellphone was found is the back seat after drinking, and if it was there, there is no way people wouldn't have seen it."

He continued, "If someone witnessed who dropped friend A's cellphone, which was turned off and then on again in the early morning of April 25 (the day of disappearance), it would give a significant lead. Not only May 11 but also earlier stages should be reviewed by checking CCTV footage," he argued.

Additionally, Professor Oh questioned the sanitation worker's refusal to undergo a polygraph test citing human rights reasons.

Professor Oh said, "If (the sanitation worker) has no direct criminal charges, why refuse (the test)? I think it would be better to take the test and say the truth."

He added, "There are parts where the public raises suspicions. There is no need to consider absurd claims, but please explain each one to resolve the doubts."

He also emphasized the police announcement that "after checking 126 CCTVs at 74 locations, there is no sign of a crime," saying, "Instead of doing it so simply, there are several more CCTVs showing Banpo Bridge, so the investigation results should be announced by verifying and resolving each suspicion one by one to end the doubts."

Finally, Professor Oh stressed, "Citizens tend not to believe people's words but rather science," urging the police to be more proactive in clarifying when announcing the final investigation results.
