The Halloween spirit has captured Sen. Ted Cruz like California authorities never could.

On Wednesday, Cruz tweeted out an image of one of the Zodiac Killer's cryptic letters, possibly reviving a two-year-old meme that suggested he was the unidentified 1970s California serial killer.

Obviously, the Texas Senator is most definitely not the Zodiac Killer; He was still a child during the span of unsolved murders that took place in the late 1960s and early 1970s.

But it's clear people love to pretend, including, perhaps reluctantly, Cruz himself. Last year, Cruz assumed his joking role as the Zodiac Killer after a fellow Senator complained on Twitter that Cruz spilled Dr. Pepper on him during a Senate Judiciary Committee hearing.

The internet's obsession with labeling Cruz as the Zodiac Killer for no particular reason dates back to around 2013, but it really picked up steam during his 2016 run for president.

Things got so out of hand at one point that a poll found about 10 percent of Florida primary voters believed Cruz was actually the Zodiac Killer, with 28 percent of voters responding that they were "not sure."

Elaina Plott, an Atlantic writer who profiled Heidi Cruz recently, said she has to clamp down on the meme within the home because of their daughter's sleuth-like propensities.

Talk about killer optics!
