Olivia Martinez-Mercado, 37, was found in life-threatening condition at her Charlotte, North Carolina, residence on July 16, 2011, and later died of critical injuries. Law enforcement initially believed her injuries might have been natural, but an autopsy determined her death was a homicide. Her boyfriend, Freddy Renteria, was identified as the primary suspect and was arrested on charges of first-degree murder after she died in the hospital.

The case underscores domestic violence as a factor in this death and the way investigative findings shifted as more information and forensic results emerged. If anyone knew Olivia, her routines, or observed concerning behavior at that address around mid-July 2011, please share what you remember.
