Luigi Mangione fired the shot heard around the world. 

Mangione allegedly shot and killed the UnitedHealth Group CEO Brian Thompson last December in busy New York City, according to police. 

Thompson was shot and killed as he walked to an early morning meeting in Manhattan. Though Mangione’s gun is said to have jammed, he cleared the jam and continued shooting.

On May 5, Andrew Witty resigned as UnitedHealth CEO, citing personal reasons. Chairman Stephen Hemsley became CEO, effective immediately. Witty will serve as a senior adviser to Hemsley.

And that’s not all.

And now the Justice Department is investigating the Minnesota-based business. UnitedHealth Group has been charged with Medicare fraud.

Medicare is a federal health insurance program in the United States for people age 65 or older and younger people with disabilities, including those with end-stage renal disease and amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease).

It was started in 1965 under the Social Security Administration and is now administered by the Centers for Medicare and Medicaid Services (CMS).

UnitedHealth Group is the largest provider of Medicare Health Plans, serving 1 in 5 Medicare beneficiaries, or nearly 13.7 million consumers. 

On Tuesday, UnitedHealth Group suspended its 2025 forecast due to surging medical costs, sending its shares down more than 10% premarket. The company is based in Minnetonka, Minnesota.

Not everyone was sad about Thompson’s killing. Some cheered.

Some 41% of American youth found the alleged killing of the UnitedHealthcare CEO, committed by Luigi Mangione, to be acceptable. 

He has been indicted on eleven state charges and four federal charges, including first-degree murder, murder in furtherance of terrorism, criminal possession of a weapon, and stalking.

Federal prosecutors are seeking the death penalty in Mangione’s federal case.
