Verdict: False

The claim is neither referenced on CNBC’s website nor its verified social media accounts. A screenshot of the purported headline shows CNBC’s website as using a “.us” extension, when in actuality, it uses a “.com” extension. In addition, a spokesperson for CNBC denied the claim’s validity in an email to Check Your Fact.

Fact Check:

A federal judge in New York has appointed death penalty expert Avraham Markowitz to Mangione’s case, according to ABC News. Mangione has been charged with “murder through use of a firearm,” which makes him eligible for the death penalty, the outlet reported.

The X post, which has been viewed over 8,000 times as of writing, claims CNBC purportedly published a headline announcing the death of Mangione. “BREAKING: MK Ultra Assassin Of United Healthcare CEO Luigi Mangione FOUND DEAD in Jail Cell,” the post reads.

The post features an image of the purported headline from CNBC announcing Mangione’s alleged death. “JUST IN! Luigi Mangione Found Dead in Jail Cell,” the headline claims.

The claim is false, however. Another iteration of the claim, which was also shared on X, shows the purported web address of the article as “cnbc.us.” Check Your Fact attempted to load the web page but received a 404 error message.

Likewise, Check Your Fact did not find any reference to the purported headline on CNBC’s website or its verified social media accounts. A search of the purported headline via CNBC’s website indicates the website uses a “.com,” not a “.us” extension.

In addition, Check Your Fact found no credible news reports to support the claim. If Mangione had actually been found dead in his jail cell, multiple media outlets would’ve covered it, yet none have. Actually, the opposite is true. On Feb. 9, Lead Stories debunked the claim. The outlet also noted that CNBC’s website uses a “.com,” not a “.us” extension, and labeled the image of the purported headline as “fabricated.”

Furthermore, a spokesperson for CNBC denied the claim’s validity in an email to Check Your Fact.

“We can confirm that article was not published by CNBC,” the spokesperson said.

Mangione is accused of stalking and murdering UnitedHealthcare CEO Brian Thompson, according to a news release from the U.S. Department of Justice (DOJ).
