Of more than 200 tips sent to the NYPD regarding the murder of UnitedHealthcare CEO Brian Thompson, none named suspect Luigi Mangione, who was arrested Monday.

Investigators revealed new evidence in the case against 26-year-old Luigi Mangione, who has been charged with the murder of UnitedHealthcare CEO Brian Thompson. Police say fingerprints found at the scene matched those found on the gun found on Mangione.

Luigi Mangione is believed to be a person of interest in last week's deadly shooting of UnitedHealthcare CEO Brian Thompson, police said Monday. The 26-year-old was arrested on firearms charges in Pennsylvania, where New York police detectives were heading to interview him amid a massive manhunt for the shooter.
