Empty Eyes is the eighteenth episode of season seven of CSI: Crime Scene Investigation.
Six showgirls are murdered in their home. One of them dies in Sara's arms, leaving behind some clues to the killer's identity.
The case appears to be based on the real-life mass murder commited by Richard Speck in 1966. Like Speck, the killer killed a number of women inside a single house, tying them up with torn sheets, raping and stabbing them. As with Speck, part of the evidence implicating the suspect was a skin mark (a tattoo for Speck, a large mole for the killer). Also, both killers tried to kill themselves with a sharp instrument after their killings, both had prior histories of sexual assaults.
