|A portrait of Hwaseong murder suspect Lee Chun-jae|
Police said he admitted to responsibility for the cases and three more crimes in the city at that time and two others before the murder of his sister-in-law.
The Hwaseong cases were again brought to light about two weeks earlier when new and advanced police investigation technology identified the suspect's DNA in evidence found in at least three of the 10 infamous Hwaseong murder cases. One of the 10 cases later turned out to have been a copycat killing.
The police have said the suspect will not be prosecuted for the Hwaseong cases even if he admits his involvement, as the statue of limitations on the Hwaseong cases expired in 2006.
Despite mobilizing tens of thousands of officers then, the police failed to even identify a suspect.
The unsolved cases inspired the 2003 hit movie "Memories of Murder." (Yonhap)
