Who are the Serial Killers in the 'Riverdale' Library?

The Zodiac Killer

Fans have been anticipating Riverdale's Zodiac Killer homage for a while now, especially after the first look at his code was revealed in this episode's promo. The Zodiac Killer is easily the most well-known killer brought up in this sequence, largely thanks to David Fincher's 2007 film on the subject.

The Zodiac Killer plagued Northern California in the 60s and 70s, mostly targeting young men and women. While he only had five confirmed kills, he regularly claimed to have killed 37 people.

The killer became famous for mailing letters to the local newspapers (not unlike the Black Hood), which were regularly accompanied by ciphers. The Zodiac Killer sent four ciphers in total, but only one has been solved to this day.

Another unsolved aspect to the case is still the killer's identity. Plenty of suspects have been brought up over the years, but there has been no conclusive evidence. The ongoing mystery of the Zodiac Killer's identity has become somewhat of a meme in recent years, with even Republican senator Ted Cruz being accused of being the killer.

The Axeman Of New Orleans

The second killer Jughead mentioned was The Axeman of New Orleans. While this killer is much more obscure than the Zodiac, elements of his M.O. have already been seen in Riverdale.

The killer was active in the New Orleans, Louisiana area from 1918 to 1919. His confirmed body count was somewhere between six and ten, with the same number of people supposedly injured by his attacks.

Like the Zodiac Killer, the Axeman gained notoriety by publishing a letter in the local paper. The letter announced his vendetta, and threatened to terrorize a household in New Orleans every night. The Axeman had one loophole, however - he wouldn't attack any home that had jazz music playing in the window.

Like the Zodiac Killer, the identity of the Axeman has ultimately never been determined.

The Phantom Killer

And finally, the third killer mentioned by Jughead holds a special connection to this episode. The episode gets its name from The Town That Dreaded Sundown, a film based on The Phantom Killer.

The Phantom Killer terrorized the Texarkana area in the spring of 1946, in what became known as The Texarkana Moonlight Murders. He largely targeted couples late at night, and ultimately killed five and wounded three.

His appearance - particularly within the film - is probably the biggest tie to Riverdale. Most renderings of the Phantom Killer show him wearing a dark jacket, with a sort of white mask over his face.

The killings were noteworthy largely thanks to the impact it had on Texarkana's citizens. The town grew increasingly hostile in the wake of the killings, with teenage citizens essentially arming themselves and attempting to bait the killer. (Sound familiar?)

Like the previously mentioned killers, the Phantom Killer was never unmasked. Hopefully the townspeople of Riverdale will get more answers.
