At the prosecution's investigation, the police reported that Yoon Mo, 52, was suspected as the culprit during the 8th case of Lee Chun-jae's serial killings.

According to the law firm Dasan and the investigative authorities, during the 8th incident of the Lee Chun-jae case, the police produced an investigation report indicating that the re-evaluation of the national fruit is necessary as a result of the first evaluation of Yun's hair and the hair suspected to be found on the scene. .

The investigative report reported that the results of the radioisotope differentiation method for the two hairs (the technique of analyzing the heavy metal components contained in the hairs, etc.) have received opinions from the orchards that the numbers of the various components appear to be the same person. It says that you should ask.

However, the results of the first sentiment on Mr. Yun's hair and the body hair found in the field were so different that they could not be regarded as the same person.

At the time, since the police had made false investigation reports, hair was collected several times. Yoon was arrested as the culprit of the eighth case of Lee Chun-jae through three additional sentiments.

The prosecution is investigating the police as driving a criminal with false documents.

The prosecution checked the police investigators at the time about the motives for manipulating the investigation report, and also illegally arrested and detained Yoon, who was asked for a thorough investigation by Dasan, and misrepresentation of the alleged and suspect reports, and the post-operation of various evidences. We are also investigating suspicions.

Yoon, who was arrested for 20 years and sentenced to eight years in prison and paroleed in 2009, has been insisting on rebellion. After Lee Chun-jae's confession, he has formally filed a lawsuit last month with the help of lawyer Park Jun-young.
