Dark Minds - Season 2

The Original Night Stalker is America's most cunning serial killer. He terrorized California with a wave of rapes and murders, leaving a trail of bizarre clues. It's a race against time, but can he be found before the urge to kill rises again?

Four young girls go missing in Massachusetts and Connecticut. Some turn up dead, some are never seen again. They all have one thing in common: blond hair and blue eyes. But are they connected in another way? Are they victims of the same serial killer?

This trip to the seaside town of Newport, Oregon is no holiday. The bodies of local girls have been turning up dumped in the forest, and it looks like the work of a serial killer. But who is he? And what twisted clues could he have possibly left behind?

The I-45 freeway between Houston and Galveston threads a dangerous land. Over 30 young girls have gone missing here, some have turned up dead, in a place called The Killing Field. It's paradise for serial killers. Time for Paradise to get shut down.

In the spring of 1992 a serial killer cut a swathe through the Mid West. Six victims across three states, shot execution style. The victims all worked in small stores just blocks from the I-70. Why the freeway? Why did he start, and what made him stop?

Not all killers prowl lonely places. In Florida there is one killer who hunts where many of us go every day. In March and December 2007 two women were shot dead as they left the same shopping mall. A robbery gone wrong? Or the work of a serial killer?

The case reads like a Hollywood slasher flick. Four young couples at remote lover's lanes, attacked in their cars by a serial killer who may be posing as a cop. One thing's for sure: the truth in this case is definitely stranger than fiction.

The billboards on Canada's Highway 16 read: Girls, don't hitchhike on the Highway of Tears. More than 30 girls have gone missing on this highway and their murders are a mystery. Is it one killer, or multiple serial killers? Will it ever be safe again?
