Key Background

Thompson, 50, was the CEO of the health insurance division of the $550 billion UnitedHealth Group and was in New York City on Wednesday for UnitedHealth Group’s investor meeting—which was called off after the shooting. He was shot from behind just before 7 a.m. on Dec. 4 outside of the New York Hilton Midtown and was hit in the back and right calf, after which the suspect fled the area on foot and on an electric bike. A Minnesota resident, Thompson had served as chief executive since April 2021 and had been with UnitedHealth Group since 2004. A video of the shooting showed the suspect walk out behind Thompson—who did not have a security detail—before firing multiple times. Prior to the arrest, police said they believed the shooting was “a brazen targeted attack” and searched New York City before saying they believed the suspect had left the city on a bus. Thompson’s wife, Paulette Thompson, told NBC News “there had been some threats,” but didn’t provide details on what the threats were. Thompson had two sons, one who just graduated from high school and one still in high school. Police had been searching for the gunman by utilizing diving teams in Central Park, flying helicopters, searching through security cameras in the area, maintaining drones and using dogs. They released several photos of the suspected shooter since Wednesday, though his face was largely covered in all of them.
