Recent cases in point:
Creepiness factor: Extreme. A death threat's a death threat. My Sister Sam's Rebecca Schaeffer was killed by a deranged fan in 1989, which resulted in anti-stalking laws being passed in California."
The Stalker Chronicles was launched with the singular mission to track the whereabouts of Heidemarie Schnitzer and see her brought to justice. After threatening to murder CSI Miami's David Caruso and two others, Schnitzer twice failed to appear in court and fled to Mexico. In February 2009, Schnitzer was captured in Tijuana. Two months later an Austrian Court convicted her for sending death threats to David Caruso. Schnitzer's release from a mental facility may not occur until 2011.
