Fingerprint Match: Mangione's fingerprints were found on a water bottle and an energy bar wrapper near the crime scene. These items were purchased at a Starbucks around 30 minutes before the shooting, further linking him to the location and time of the crime.
Writings and Manifesto: Investigators found a three-page handwritten "claim of responsibility" and other writings in Mangione's possession at the time of his arrest. These documents included to-do lists and notes justifying his plans, as well as references to his back injury and difficulties with the insurance industry. The writings also indicated ill will towards corporate America and the health insurance industry.
Forensic Evidence: Additional forensic evidence, including DNA and fingerprints on a cellphone recovered from Mangione, has been processed. While no fingerprints were found on the bullets, the overall forensic evidence supports the connection between Mangione and the crime scene.
Surveillance and Timeline: Surveillance images from the Starbucks where Mangione purchased items before the shooting were among those publicized as authorities searched for the shooter. This timeline and surveillance evidence further corroborate his presence near the crime scene at the relevant time.

These pieces of evidence collectively provide a strong case linking Luigi Mangione to the killing of Brian Thompson.
