Detective Vance slowly arrived at the cold, dark, abandoned warehouse where they found the lifeless body of a young woman. Thick dark blood pooled around her head, staining the cold concrete floor a deep crimson in the harsh fluorescent light. A single delicate silver locket lay tightly clutched in her pale, stiff fingers, catching the attention of the seasoned investigator. He quietly knelt down beside the tragic young female victim, knowing this brutal killing would become his most challenging case.
