(NewsNation) — Alleged UnitedHealthcare CEO killer Luigi Mangione's manifesto reveals he targeted victim Brian Thompson, according to court documents.

The Manhattan District Attorney's Office released the manifesto Thursday, which delved into the details and process Mangione put into thought behind the killing back in December. Mangione is accused of fatally shooting Thompson in the back and the leg in front of the Hilton Hotel in New York City.
