NEW YORK (AP) — Luigi Mangione pleaded guilty on Friday to federal stalking charges in the killing of UnitedHealthcare CEO Brian Thompson, admitting matter-of-factly that he trailed the executive to an investor conference in 2024 and gunned him down on a New York City street.

Mangione, 28, said he even used a ruse to glean information about the event, contacting the health insurance company ahead of time under the guise of being an investor at a multibillion-dollar firm.

“On the morning of December 4, 2024, I shot Mr Thompson in Manhattan, and he died,” Mangione told the court as Thompson’s wife, Paulette, took several deep breaths and repeatedly wiped tears from her eyes. A supporter put an arm around the wife and held her tight.
