A possible motive has been revealed for the man who allegedly gunned down a major health insurance CEO.
New York prosecutors have charged 26-year-old Luigi Mangione with murdering Brian Thompson last week.
He was arrested in a Pennsylvania McDonald's yesterday, reportedly carrying a firearm and a hand-written document.
US Correspondent Richard Arnold told Heather du Plessis-Allal it was critical of the healthcare industry.
He says Mangione wrote about how these "parasites had it coming" and apologised for any trauma, but said it had to be done.
Arnold says it was a virtual confession, with the accused saying the note would only be read if he was killed or captured.
