A judge in New York state has dismissed two terrorism charges against Luigi Mangione, the alleged killer of UnitedHealthcare CEO Brian Thompson.

Judge Gregory Carro also ruled second-degree murder charges against Mangione could stand during a hearing on Tuesday morning.

He stated that prosecutors had failed to establish enough evidence to justify the terrorism-related murder charges sought against Mangione.

Mangione is accused of gunning down Thompson on a busy Manhattan street in December of last year.

In addition to the New York state criminal proceedings, Mangione also faces federal murder charges, which could lead to the death penalty.
