The investigation into a case that has fallen into a maze has been revealed.

On the 40th episode of E Channel’s ‘Brave Detectives 4’ that aired on the 27th, Incheon Yeonsu Police Station’s Violent Crimes Unit Chief Superintendent Park Ki-hoon, Former Senior Superintendent Yoon Oe-chul of the Scientific Investigation Unit(KCSI), and Superintendent Kim Jin-soo appeared and revealed the investigation logs they personally solved.

The first incident began with a report of a person bleeding on the sidewalk of an eight-lane road.The victim was found dead, wearing only a blood-soaked running shirt.The victim was a taxi driver in his 40s, and the father of a one-year-old child, which made it even more heartbreaking.The victim’s taxi, which was not at the scene, was found engulfed in smoke in a residential area a five-minute drive away.Inside the car, the car manual appeared to have been used as a kindling.Two men were captured moving busily on nearby CCTV, one of whom was holding the victim’s uniform top.In addition to the victim’s bloodstains, four traces of the perpetrator’s blood were found, but at the time, it was difficult to find anything other than the fact that he was a B-type male using forensic technology.The suspect’s vehicle was also captured, but it was difficult to identify him, and since there was no DNA match, the case remained unsolved.

Detective Park Ki-hoon, who joined the unsolved crime team 12 years later while the case was being reinvestigated, looked at the taxi photo again and suspected the source of the vehicle manual.Since there was no evidence of the inside being rummaged through, it could have been something the criminal had brought in advance.Three new notes were discovered through the vehicle manual that was kept as evidence.After that, they guessed the vehicle model, series, and date of manufacture, and by investigating about 100,000 vehicles, they were able to narrow down the number of suspects to 300.In addition, they investigated the vehicle list from the previous investigation, and found one person whose fingerprints matched.However, he had transferred the vehicle to someone else a month ago.After continued investigation, they were able to identify Choi(pseudonym)among the two suspects.Four days after the crime, Choi sold the vehicle in a hurry and fled to the countryside.After finding all of Choi’s records, they were able to obtain DNA matching results by securing the tissue he had thrown away in the company cafeteria.

Choi, who was arrested after 16 years, denied the charges, saying he did not remember.The accomplice was a year older than Choi and was in the same prison as him.The accomplice admitted only to the robbery and pushed the murder to Choi.He claimed that he committed the crime in a taxi he got into by chance, and that the victim, who was locked in a bag, escaped when he tried to find out the card PIN, and that Choi chased after him and killed him.However, the forensic examination results showed that the crime could only have been committed by two people.The accomplice still denied the murder, and Choi also never admitted to the crime, and they were ultimately sentenced to life imprisonment.


The incident introduced by KCSI started with a report that a fire seemed to have broken out in the top floor of an apartment building.However, while no flames were visible in the smoke-filled living room, there were flames elsewhere, making it look different from a typical fire scene.Unfortunately, the body of a woman who had been burned was found inside a blanket and clothes.The victim was a woman in her 40s who was the owner of the house and lived alone.The auxiliary lock on the front door could only be pressed from inside the house, so everyone was shocked to see that the criminal had not gone through the door, but had moved over the veranda and rooftop.While checking the list of nearby criminals, a 20-year-old male social service worker(alternative service worker)living across from the victim’s house caught the eye.He had been placed under juvenile protection for special robbery as a minor, and claimed that he did not remember the incident because he had returned home drunk after work on the day of the incident.

The victim’s cell phone was found as lost property in an intercity bus terminal bathroom, and the fact that the criminal made about 20 calls after the crime, most of which were known to be paid ‘phone ting’ numbers, made people even more angry.He also called 114 and asked for the number of a laundry, and when he went to the laundry, they said that they found blood on the end of the sleeve of a brown Mustang and that he knew the face.The criminal was a male social service worker in his 20s.He admitted to the crime, claiming that his motive was robbery and sexual assault.He showed no remorse, saying that after setting the fire, the door wouldn’t open, so he headed to the rooftop for his life, but everyone was outraged when he was sentenced to a mere 15 years in prison.
