Pet Rock
The woman hadn’t shown up for work in two days, and her boss reported her missing. When her body was found, the evidence pointed to suspects who claimed they had nothing to do with the crime. The victim, herself, would help police prove they were lying.
Lights Out
Whoever stabbed the young mother to death had also savagely beaten her four-year-old daughter. Police had a suspect, but not enough evidence to tie him to the crimes. It would take 15 years and advances in DNA technology to bring the killer to justice.

Hundreds of Reasons
The assistant manager of the restaurant had been stabbed to death. Police knew why he’d been killed: $8,000 was missing from the safe. As to who was responsible, his family and friends couldn’t even imagine who’d want to hurt him.
Writing on the Wall
The victim was well liked and successful, which made the brutality of the crime hard to understand. She’d written a name on the wall, presumably that of the killer, in her own blood. But to catch the killer, police would have to read between the lines.

All That Glitters Is Gold
A bullet-riddled car, a missing driver, and no witnesses. Was this an ambush or a random attack? Had the victim been abducted or was she dead? The answers lay in a unique clue, so tiny it was measured in millionths of a meter.

Dollars and Sense
Even though the victim was burned beyond recognition, police were able to create a composite sketch from his remains and identify him. But knowing who he was isn’t enough. Investigators still had to determine where he was killed and who wanted him dead.

Smiley Face
