Netflix’s latest docuseries Night Stalker: The Hunt for a Serial Killer opens on a flourishing Los Angeles—the city is hosting the 1984 Olympics, both the Queen and the Pope had recently visited, and crime is on the decline. But things quickly turn dark as the city is haunted by an active serial killer linked to dozens of chilling crimes. The horrific four-part series details the crimes of the Night Stalker (later identified as Richard Ramirez), a serial kidnapper, burglar, rapist, and murderer who terrorized the city from the spring of 1984 up until his August 31, 1985 arrest. Netflix’s documentary relies mainly on interviews with survivors, police officers, and news footage to examine those grim months in Southern California.
