Forensic Files - Season 13 - Eps 36: Writing on the Wall
The victim was well liked and successful, which made the brutality of the crime even harder to understand. In the final moments of her life, she'd written a name on the wall, presumably that of the killer – in her own blood. But this wasn't an open and shut case and, in order to solve it, investigators would have to read between the lines.
