Luigi Mangione watched stoically in court Monday as prosecutors played surveillance videos showing the killing of UnitedHealthcare CEO Brian Thompson on a New York City sidewalk last year and Mangione’s arrest five days later at a McDonald’s in Pennsylvania.

The videos, including footage from the restaurant previously unseen by the press or the public, kicked off a hearing on Mangione’s fight to bar evidence from his state murder trial, including the gun prosecutors say matches the one used in the Dec. 4, 2024, attack.

Mangione, 27, pressed a finger to his lips and a thumb to his chin as he watched footage of two police officers approaching him as he ate breakfast at the McDonald’s in Altoona, Pennsylvania, about 230 miles (about 370 kilometers) west of Manhattan.
