The robbery and murder case, which has not even outlined the perpetrators for 20 years, has finally been resolved due to improved genetic (DNA) analysis techniques and the detective's persistence.

The Gyeonggi Ansan Danwon Police Department announced today (7th) that after investigating Mr. A (41) on charges of robbery and murder, it was sent to the prosecution with the opinion of the recent prosecution.

On September 8, 2001, Mr. A sneaked into the house of a townhouse B (50s) in Ojan-dong, Danwon-gu, Ansan City, and woke up while trying to steal money after sneaking up and binding B, who had slept with her husband. He is accused of killing Mr. B's husband by stabbing him several times with a weapon.

Mr. A and others also injured Mr. B by wielding a weapon, and then ran away by stealing 1 million won in cash.

At the time, the police secured a number of tools that Mr. A's party used in the crime, including black tape, and requested gene (DNA) analysis, but science and technology at that time could not detect DNA.

In addition, Mr. A's party targeted Mr. B's couple, who had no one-sided knowledge, and entered Mr. B's house through an unlocked window through a gas pipe.

In June of last year, nearly 20 years later, the Gyeonggi Southern Police Agency, to which the Ansan Danwon Police Station belongs, was working on the final paperwork to complete the re-investigation of the'Lee Chun-jae serial murder case', which remained the worst long-term unsanctioned case in the history of a violent crime in Korea.

The re-investigation of the case, which took place 34 years after the first incident, has resulted in finding the serial killer Lee Chun-jae, who has not been revealed.

Lee Chun-jae was caught by matching DNA detected in evidence in five of the 14 murders he committed.

The latest analysis techniques that can identify even decades-old DNA have rekindled the arrest of criminals in the Ansan Danwon Police Station, who remembered the murders 20 years ago.

They sent evidence of the robbery and murder that was in the evidence room of the police station to the National Institute of Scientific Investigation and ordered DNA analysis again.

A month later, in August of last year, a response from the National Fruit Tree saying that male DNA was detected on the black tape used to bind Mr. B was sent. As a result of comparing this DNA with the inmate's DNA database, A is currently being held in Jeonju Prison for another crime. It has been found to match Mr.

The police interviewed Mr. A and inquired about the robbery and murder without revealing the results of the DNA analysis, and he stubbornly denied the charges.

Then, upon hearing the result of the DNA analysis, he said, "If so, the result of the analysis will be correct," he actually admitted to the charges and refused to interview the police.

Mr. A made no statement about who the accomplice was.

In the evidence of this incident, including black tape, no DNA other than that of Mr. A has been detected to date, so the police are continuing an investigation to find an accomplice 20 years ago, targeting people around Mr. A's surroundings.

A police official said, "The detectives didn't forget about the long-term unsanctioned case in the building, so we caught the killer late," he said.
