The police gave an update of the investigation of the death of Son Jung Min, the medical student who was found dead in Banpo Han River Park after six days he went missing. 

Ever since the incident first occurred, it has been gaining much media attention as there were many questions and mysteries as the missing person case turned into a murder case. 

On May 27, the Seoul Metropolitan Police Agency held a press conference at the Naeja-dong office in Jongno-gu, Seoul. The police agency stated, "There is no crime-related evidence in the case of the death of Son Jung Min. We are investing with all possibilities in mind so please trust in the police and keep watch."

The police stated that there was a taxi driver's statement regarding the suspicion that friend A went into the water with Son Jung Min. They explained, "The driver of the taxi, which A rode home at around 4:42 AM on the 25th of last month, stated that he was not able to see if A's clothes were wet but the back seat was not wet during the internal car washing process after the end of his shift."

In addition, the police explained why A had Son Jung Min's cell phone by saying, "We are checking the facts because A was not able to give an exact explanation to why he had Jung Min's phone."

The police also spoke about the claims that Son Jung Min is afraid of water, so he will not enter the water himself. They explained, "We've secured photos and videos of Mr. Jung Min at the beach and in the waters so we are checking the exact circumstances of him entering the water."

Currently, the police have analyzed the surveillance footage and information videos around the Banpo Interchange, which is about 180 meters away from Jung Min's final whereabouts. The police are also checking the relevance of the sightings by specifying passers-by who appear on the video.

The investigation information released by the police includes the family investigation log, cell phone, laptop, vehicle black box forensic analysis, communication investigation, and surveillance analysis around the residence. In addition, A's clothing has been sent to the National Forensic Service for analysis as well.

The police said, "We are focusing on clearly identifying the cause of death in accordance with Son Jung-min's autopsy that revealed the cause of death was believed to be drowning."

They continued to say, "the result of forensic analysis of the late Son Jung Min's clothing and socks from the National Forensic Service showed no unusualities such as blood. In addition, the soil attached to the socks was similar with the soil from the 10m radius location range from where he disappeared."

The police stated that they have secured 16 witnesses so far and have conducted field investigations, cell phone forensics, and lawful hypnosis to verify the authenticity of their statements. They are continuing their best to find additional witnesses.
