Look Who's Stalking

Two teenage girls are targeted by obsessed stalkers; one survived her harrowing ordeal; the other was tragically caught up in a murderous plan carried out by her fanatical stalker.

A man sends hundreds of threatening massages that document his fixation for a former class mate; a firefighter is exposed as the most prolific stalker of women in U.S. history.

A woman's stalker disappears for a few years, only to make a terrifying return; a predator breaks into his ex-girlfriend's house.
