Who is Luigi Mangione, CEO shooting suspect?

A profile is emerging of the 26-year-old man charged with murder over last week's fatal shooting of UnitedHealthcare's chief executive, Brian Thompson, in New York City.

Police announced on Monday they had arrested Luigi Mangione after he was recognised at a McDonald's in Altoona, Pennsylvania.

The Baltimore, Maryland, native was found in possession of a so-called ghost gun, a largely untraceable firearm, and a three-page handwritten document that indicated "motivation and mindset", officials said.

Mr Mangione comes from a prominent family in the Baltimore area who are known for businesses including country clubs, nursing homes and a radio station according to local media.

The suspect's paternal grandparents, Nicholas and Mary Mangione, were real estate developers who purchased the Turf Valley Country Club in 1978 and Hayfields Country Club in Hunt Valley in 1986.

Shortly after the suspect was charged, Republican state lawmaker Nino Mangione - believed to be Mr Mangione's cousin - released a statement saying the family was "shocked and devastated".

"We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved", the statement read, signing off as "The Mangione Family".
