On May 5, 2003, Chi Hyon Song, a 30-year-old mother, along with her two-year-old son, and their 56-year-old nanny Eun Sik Min, were all slain, execution-style, in their modest apartment in Koreatown.  LAPD detectives first suspected Song’s husband, but his alibi was air tight. With no other suspects, the case goes cold. That is, until 2008, when a law enforcement DNA database turned up a new connection to the case.
