Luigi Mangione is expected to enter a guilty plea in his federal case on Friday, according to sources familiar with the matter who spoke to ABC News. The announcement is scheduled for a 11 a.m. hearing in federal court.

While the plea is anticipated, sources cautioned that the plans are not final and could change before the hearing. Neither the prosecution nor the defense teams have commented on the developing situation.

Mangione is accused of killing UnitedHealthcare CEO Brian Thompson on December 4, 2024, in Midtown Manhattan. He was apprehended in Pennsylvania following a five-day manhunt.

Manhattan District Attorney Alvin Bragg indicted Mangione on first-degree murder charges on December 17, 2024. Federal prosecutors subsequently announced separate charges, including stalking and murder, on December 19, 2024. Mangione had previously pleaded not guilty to charges in both the state and federal cases.

Over the past year, the scope of the charges in both legal proceedings has narrowed. In January, U.S. District Judge Margaret Garnett dismissed the federal murder and firearm charges, which had carried the possibility of the death penalty. In September, Judge Gregory Carro had previously dismissed the first-degree murder and terrorism charges in the state case.

In the current state case, Mangione still faces charges of second-degree murder, criminal possession of a forged instrument, and multiple counts of criminal possession of a weapon. His trial in the state case is scheduled to begin on September 8. His federal trial had been set for January 5.
