This blog post summarizes the timeline and trial outcomes of the Kim Myung-cheol disappearance case and the subsequent Park Byung-jun death case, as covered in episodes 788 and 817 of SBS’s ‘Unanswered Questions’.
Case Overview
On June 12, 2010, Kim Myung-cheol—a 180 cm tall, physically fit amateur basketball player and corporate recreation instructor who was engaged to be married—went missing just one week before his parents’ meeting with his fiancée’s family. According to testimony from a coworker prior to his disappearance, Jo Sang-pil (pseudonym), a longtime friend of Kim Myeong-cheol’s fiancée, approached Kim Myeong-cheol and suggested that he knew someone looking for a three-day, two-night recreational activity job. Thinking he might have to entertain this person, Kim Myeong-cheol borrowed his fiancée’s high-limit credit card and drove out, even though the destination was nearby.
However, something strange happened that night, and that was the last time he was seen. Kim Myung-cheol’s fiancée, Park Hyun-joo, received a strange text message from him announcing their breakup, and an unknown woman reportedly called Kim Myung-cheol’s cell phone, saying she was leaving with him. The next day, Park Hyun-joo went to see Jo Sang-pil, the last person Kim Myeong-cheol had met with. Jo Sang-pil stated that Kim Myeong-cheol had borrowed money using the car he’d taken as collateral and received 30 million won in cash under the pretext of an “activity deposit.” He added that Kim Myeong-cheol had left that day with 50 million won in cash, claiming he had another appointment. Kim Myeong-cheol’s parents also received a text message from their son stating that he had incurred a large debt and could not return home for the time being.
The family immediately filed a missing person report with the police and began tracking his last known movements through cell phone location tracking and eyewitness accounts. According to testimonies from acquaintances, Kim Myung-cheol was known for his upright character and was not the type to cheat on his girlfriend; his only debt was a student loan of about 4 million won. Furthermore, the text message pattern Kim Myung-cheol used was different from his usual style, and the person who habitually used that exact pattern was Jo Sang-pil.
Among the eyewitness accounts, there was a testimony stating that someone saw Kim Myeong-cheol, who appeared to be intoxicated or unconscious, being carried on the back of one person while another accompanied them into a shop. Police investigations confirmed that the two individuals were Jo Sang-pil and a man introduced as “Director Choi,” who was reportedly looking for a recreation instructor. However, Director Choi was not a corporate employee but a delivery driver for a local late-night snack shop. The two underwent intense police questioning, and Director Choi reportedly confessed to almost everything. According to his statement, he visited several hospitals to obtain a prescription for sleeping pills before meeting Kim Myung-cheol, and he went to a bar in advance to mix the sleeping pills into the alcohol.
On the other hand, Jo Sang-pil initially claimed that Kim Myeong-cheol had left because he had another appointment. Later, while admitting that he had carried the intoxicated Kim Myeong-cheol into his shop, he denied the crime, stating that Kim Myeong-cheol had sobered up and left on his own shortly afterward. However, nearby CCTV footage did not capture Kim Myeong-cheol walking out on his own, and suspicions grew even stronger.
This was not the only suspicious detail. According to a real estate agent near Jo Sang-pil’s shop, before renting the space, Jo had insisted that it must have a water supply and be in a location where noise late at night would not disturb the neighbors. After renting the space, he covered all the front windows with stickers, and shortly thereafter, it was confirmed that an unconscious Kim Myeong-cheol had been carried inside. A police investigation revealed that the shop’s water usage in June 2010 was approximately 40 tons higher than in other months, indicating that enough water had been used to fill the shop.
The shop door was rarely opened in June, and Jo Sang-pil stated that he was the only one who entered the shop to conduct personal business; even when others visited, he would open the door just slightly to peek out and speak with them. During the investigation, Kim Myeong-cheol’s hair and bloodstains were discovered at the shop. The pattern of the bloodstains suggested a struggle, appearing as though Kim Myeong-cheol was pinned down while Jo Sang-pil struck him from above. Additionally, the excessive water usage and the repainting of the wallpaper were interpreted as evidence of an attempt to conceal something.
It was also suspicious that all these preparations were made in such a short period. Cho Sang-pil heard about the engagement on June 2, quickly leased the shop through a real estate consultation on June 3, proposed a business deal to Kim Myung-cheol on June 8, purchased sleeping pills on June 10, secured a bar on the 11th, and met Kim Myung-cheol on June 12. The strange text message mentioned earlier was also revealed by the police investigation to have been written by Cho Sang-pil’s friend.
Trial Outcome and Subsequent Events
Cho Sang-pil was arrested and detained on July 3, 2010, along with his accomplice, Director Choi. In the first trial, the prosecution sought a 15-year prison sentence for Jo Sang-pil under the Act on the Punishment of Violent Acts, etc., on charges of confining and assaulting Kim Myung-cheol, and a 3-year sentence for his accomplice, Director Choi. The prosecution explained that they sought the 15-year sentence because the principal offender, Jo Sang-pil, had meticulously planned and prepared for the crime in advance, and because the nature of the crime was severe—including the use of sleeping pills—and he showed no remorse.
During police questioning and in his final statement, Jo Sang-pil claimed that he had only kidnapped Kim Myeong-cheol and absolutely did not kill him; it is reported that he shouted at the prosecuting attorney to produce evidence that he had killed him. However, no murder weapon was found, and since it was difficult to establish the charge of murder based solely on bloodstains and hair found at Jo Sang-pil’s shop, the ruling was partially revised in the second trial.
On March 24, 2011, the 2nd Criminal Division of the Suwon District Court ruled that while evidence showing Cho Sang-pil had drugged, confined, and assaulted Kim Myeong-cheol was accepted, it was difficult to conclude that he had planned to murder Kim Myeong-cheol based on that evidence alone. However, considering the decisive link to Kim Myeong-cheol’s disappearance and the lack of remorse regarding the incident, the court reduced the first-instance sentence of 15 years’ imprisonment to 7 years. Co-defendant Director Choi was sentenced to one year in prison, as he was found to have merely participated in the crime without any specific intent to commit it.
As the social backlash grew following the broadcast of “Unanswered Questions,” online sleuths tracked down the personal information of suspect Jo Sang-pil and his fiancée Park Hyun-joo, revealing Jo Sang-pil’s past history. He had a history of involvement with so-called gangsters and had an identical twin brother. Six months later, SBS aired the second episode of “The Missing Fiancée,” providing additional coverage of Jo Sang-pil’s trial and past history.
The second episode covered how the Jo brothers were identified as suspects in a death six years prior that had appeared to be a staged accident. In May 2009, Park Byeong-jun died of carbon monoxide poisoning while showering in his bathroom.
Paramedics who responded to the call encountered Jo Sang-pil at the scene, and during questioning, Jo stated that Park Byung-jun frequently took sleeping pills. Police investigations revealed that the bathroom where Park Byung-jun died was adjacent to an office leased under Jo Sang-pil’s name, and evidence emerged that Jo had inquired multiple times with the insurance company about the potential payout amount in the event of an accident prior to Park’s death.
The monthly premium for the insurance policy under Park Byeong-jun’s name was approximately 1.5 million won, and the death benefit was about 1.7 billion won. Since Park Byeong-jun’s monthly salary at the time was around 1 million won, people close to him stated that it would have been difficult for him to pay the premiums. The beneficiary of the insurance policy was Cho Sang-pil’s older brother, Cho Jae-pil (pseudonym). Subsequently, Cho Sang-pil changed the beneficiary to his older brother. Ten days later, he purchased LP gas, installed a gas water heater the following day, sealed the bathroom window with silicone, and removed the safety device inside the water heater to cause a carbon monoxide leak.
The Cho brothers attended Park Byeong-jun’s funeral, cremated the body, and scattered the ashes in the mountains, completing the funeral rites. Following a two-year police investigation, this case led to the arrest of the Cho brothers on murder charges in 2011.
The Park Byeong-jun case, in which circumstances similar to the Kim Myeong-cheol disappearance were discovered, resulted in Cho Sang-pil being sentenced to life imprisonment during the trial. After reviewing circumstantial evidence—such as sleeping pills mixed into alcohol and a blank promissory note—along with the similarities between the two cases, statements from an accomplice, and various pieces of evidence recovered from the store, the court determined that Cho Sang-pil’s past conduct, the meticulous nature of the crime, his disregard for human life, and his complete lack of remorse were sufficient to establish guilt for murder based on circumstantial evidence alone.
Cho Sang-pil himself insisted until the very end, “I absolutely did not kill anyone!” but the court, after weighing all the circumstances, handed down a severe sentence.
