Trolls bash tipster who helped catch Luigi Mangione, alleged killer of UnitedHealthcare CEO Brian Thompson

Tasteless trolls showered praise on the Ivy League grad suspected of executing UnitedHealthcare CEO Brian Thompson in New York City — and even threatened the McDonald’s worker who helped catch the fugitive.

The internet erupted Monday after anti-capitalist Luigi Mangione was chomping on corporate fast food in an Altoona, Pa., McDonald’s after an eagle-eyed worker recognized him from surveillance footage of the alleged assassin.

“To the stupid b–h that ratted out my baby Luigi Mangione…you will be dealt with,” wrote another, along with a violent “Family Guy” GIF showing one character shooting someone in the head.
