The DNA of the Martian serial killer suspect Chun Jae-jae (56) was not detected in the Mars Eighth Case Evidence.

Investigators at the Gyeonggi South Korean Police Agency, who are investigating the case, said in a briefing on Wednesday that "the latest information was informed that the DNA of other men, including Lee Chun Jae's DNA, was not found."

The 8th incident was discovered on September 16, 1988, when Park was sexually assaulted and killed at Park's home, Jinan-ri, Taean-eup, Hwaseong-gun, Gyeonggi-do.

The case ended in punishment after the criminal was arrested, but Lee Chun-jae confessed last month that he had committed 14 murders and 30 sex crimes, including all 10 Hwaseong incidents and four in Cheongju, Chungbuk.

Yoon Mo, 62, who has been jailed for twenty years for being the culprit of the eighth case, is preparing for a reconsideration claim, saying that he has made a false confession and made an unfortunate one because of police coercion investigation.

In order to verify the credibility of Lee Chun-jae's confession, the police occurred in Shamrock and other areas found at the scene of the evidence that remained at the time of the eighth incident. I sent a window to the National Institute of Scientific Investigation and asked for analysis.

Guk also finalized the same results in the evidence of the 10th case, which he analyzed earlier.

A police official said, "The evidence of the 8th case was already meaningless at the time, so it was less likely to come out of the suspect's DNA from the beginning." The fact that there was an ambiguous part of the fruit tree has been carried out several times and we have been finally informed that the suspect's DNA has not come out. ”

To date, there have been five cases of Lee's DNA coming from evidence, including the 3rd, 4th, 5th, 7th and 9th events of Mars.

DNA analysis of secondary case evidence is ongoing.

Among the murders that Chun Jae-jae confessed, police are currently investigating the disappearance of the body of Kim Mo (9 years old) who disappeared in Taean-eup, Hwaseong-gun on July 18, 1989.

Lee Chun-jae confessed to the incident that he killed Kim and abandoned Kim's body with oil products nearby.

However, there is a distance of more than 100 meters between the place he points to and the place where the oil was actually found.

At the time, about five months after Miss Yang disappeared, the police found about 10 oil products, including skirts and backpacks, in the nearby Yasan. I noticed the results.

Police at the time were confirmed to have not informed Kim's family of the findings.

A police official said, "I asked the investigators why they didn't tell me that they found the oil, but I can't remember it because it's too old."

On the other hand, Lee Chun-jae has been reported to be consistently presenting the confessions.

A police official said, "We have been preparing newspaper reports and investigating important issues by case after the suspect's arrival."
