In a quiet neighborhood, a frightening figure in a hockey mask appears. Then another man disappears.

A horror film director and a seasoned homicide detective match wits in a high stakes game of cat and mouse.

Police recover a deleted document from Mark Twitchell’s computer that reads like a script for a horror film. But was it more than just fiction?

He wanted dinner and a movie. His “date” seemed to want something else entirely…

After Twitchell is arrested on Halloween, a city debates whether he is a monster or a master manipulator.

At trial, Twitchell plays a surprising card. Will he walk, or will everything come tumbling down?

Hey Dateline fans! As a bonus for you, we’re sharing the trailer for Murder in the Moonlight, an all-new original podcast series from Dateline and Keith Morrison.

In this podcast, Keith Morrison takes listeners to a quiet farmhouse on America’s Great Plains, where Sharmon and Wayne Stock have just celebrated Easter with their big, loving family. That night, under a pale moon, the couple is shot to death in their bedroom. The investigation includes four suspects, spans three states, and comes down to a single shiny clue: A gold ring found at the scene of the crime.
