According to the Gimpo Police Station, You called an emergency services center at 4:57 p.m. to report that his wife had "fainted" at their home in Yangchon, Gyeonggi Province, and was not breathing.
When emergency personnel arrived at his house in an ambulance, his wife was found to be unresponsive.
Police officers, who arrived at the scene following a report by the emergency staff, found the wife's body to be covered in bruises with her face and head swollen. They also found a bloodstained golf club and three empty liquor bottles nearby, one of them broken.
You, 55, admitted to killing his wife, saying he was drunk at the time and "accidentally" hit and kicked her while they were arguing. He claimed that he used his fists and feet to punch and kick her, but did not hit her with the golf club or the bottles.
Police immediately detained You and are questioning him about the details of the crime. They suspect the former councilor used the golf club to hit his wife's head and are considering whether to seek murder charges, premeditated or otherwise.
Police will request the National Forensic Service to conduct an autopsy on the victim today to narrow down the exact cause of death. They will also ask the prosecution to request an arrest warrant from a local court.
The killing was a shock to Gimpo residents, as You's behavior was far from that seen in public.
You was head of the city council from 2012 to 2014, and has been in charge of a local welfare foundation since 2017. He was also a member of a local anti-crime committee designated by the Ministry of Justice.
Holding certificates in social welfare care and juvenile protection, he had been carrying out media campaigns against violence.
On his blog in January 2015, You wrote, "There is no justification for violence. No matter what, all human beings are the same as noble, respectable individuals."
