REVIEW: The Zodiac Killer is a high-technology hunt for one of the world’s most elusive serial killers
The case of the Zodiac Killer has mystified detectives for half a century. The identity of the serial killer who communicated with the press through a series of taunting letters and unbreakable codes has never been discovered.
HISTORY’s latest documentary series, The Zodiac Killer: Case Closed?, seeks to identify the Zodiac Killer once and for all, using high technology alongside traditional investigative techniques. Can it solve the mystery of America’s most infamous unidentified serial killer?
The Zodiac Killer is one of the world’s most unusual serial killers. For one thing, he has never been identified. For another, all descriptions of his physical appearance are vague. Finally, he wrote letters to the press containing coded messages – which the FBI and CIA were never able to solve. All of these things make him a fascinating subject of study for a documentary.
It means investigators must use some of the most advanced existing codebreaking techniques to solve his baffling ciphers, which are said to reveal the killer’s true name. Investigators must try to recreate the Zodiac Killer’s brain in a computer by plugging in the killer’s known writings and code. It’s the same technique that the Allies used to break the Nazi Enigma code during World War II.
Elsewhere, a field team investigates the case of an early murder that could be linked to the seven ‘official’ Zodiac Killer murders. If they were the work of the same culprit, could the younger Zodiac Killer have made stupid mistakes that may reveal his identity?
The Zodiac Killer: Case Closed? identifies several new leads in a case that has perplexed the world for decades. The documentary systematically uncovers and analyses evidence to make some shocking conclusions. The unique nature of the Zodiac Killer means that this is quite different from the typical crime documentary. It’s a high-technology hunt to identify a killer that – for all we know – could still be alive and free.
