Forensic Files S05E11 - Lasting Impression

When the decomposed body of a young girl is discovered, police have no clues to her identity. But days earlier, a stabbing victim told them she thought she might have witnessed a murder. Police think the cases might be related, and to prove it, turn to bug larvae found on the body and a surprise piece of evidence: a tiny wad of chewing gum found near the victim's body.
