Luigi Mangione, the suspect arrested in connection with the killing of UnitedHealthcare CEO Brian Thompson, was linked to the crime through fingerprints and a gun recovered from him.

• The gun found by Pennsylvania police matches three casings found at the assassination site.
• Mangione also had a 3D-printed gun in his possession when arrested.

• His fingerprints were matched to those found at the scene.

  Police also found handwritten notes that they believe could be a "claim of responsibility".

Police are examining writings they believe were authored by Mangione that include a three-page "claim of responsibility."

• Some writings detail Mangione’s physical pain from a back injury he sustained in July 2023.
