User Accidentally Predicts Name of Suspected UnitedHealthcare CEO Killer in Joke X Post: 'Guys I Didn't Know Anything I Swear'

One social media user accidentally predicted the name of the suspected UnitedHealthcare CEO killer in a post just days before the suspect's arrest.

On Dec. 4, the user @whambamcamm_ shared a video of a Mario-themed video game known as "Find Luigi," where users have to find a floating Luigi head as dozens of other heads of other Mario characters bounce around the screen.

The user captioned the post, "pov ur a cop trying to find the united healthcare shooter and he's a 5'10" white guy in new york."

The joke, which went viral and amassed more than 160,000 likes, was in response to another tweet about the search for the suspect, in which they identified the suspect as a "a white male, 5'10" tall."

Little did the user know, the suspect's name was actually the name of the game, so therefore police were actually trying to "Find Luigi." The suspect was identified by police as Luigi Mangione, and was taken into custody Monday.

"guys i didn't know anything i swear," the user tweeted shortly after the suspect was identified by news outlets online. "I DIDNT KNOW."

As more news of the suspect came out, the user joked, "mamma mia this doesn't look good," in another tweet, playing into the Mario theme.

Other users began messing with the user as well.

"You are a person of interest now start running i fear," one user commented. "NYPD owes you a 10k reward," another person tweeted.

"do you work at mcdonalds in Altoona," one user tweeted. Mangione was reportedly arrested at a McDonald's in Pennsylvania after a worker there recognized him from photos released by investigators.

Mangione, 26, was arrested and charged with second-degree murder in connection with the death of CEO Brian Thompson. Authorities believe that the shooting that took place in Manhattan last week was "targeted," as reported by ABC News.
