Yvone E. Rettig, 39, was found dead inside her home in the 7700 block of E. Frito in Mesa, Arizona, on January 31, 2004. Authorities ruled her death a homicide, but no arrests were ever made and no suspects were publicly identified. The initial investigation produced leads that later went cold, and the case was eventually classified as a cold case by the Mesa Police Department.

Her death remains an open and active investigation with questions about who was responsible and what happened that winter day. Anyone who knew Yvone, who lived in that neighborhood then, or who has information that could help investigators is urged to come forward.
