Seong allegedly dumped the body near Dumulmeori, where the North and South Han rivers meet.Police launched an investigation on Jan. 21 after one of Lee’s acquaintances reported that he could not be reached. Investigators later identified Seong as a suspect and placed him under emergency arrest.Seong admitted to the killing during police questioning, saying the crime was not premeditated and occurred during an argument, according to police. He has since been indicted and is currently standing trial.The search for Lee’s body had been hampered by the weather, and parts of the river were frozen.Police are considering transferring the body to Seoul Dobong Police Station, which initially handled the murder investigation, after formal identification procedures are completed.
