Immediately after the federal plea, the defence asked the New York judge to dismiss the state indictment under New York rules prohibiting certain successive prosecutions for the same conduct. Judge Carro gave prosecutors until 9 October to respond and cancelled the trial scheduled to begin on 8 September. The next court appearance is set for 10 December.

Judge Gregory Carro found that the evidence presented to the grand jury was insufficient to demonstrate the intent required to classify the killing as an act of terrorism under New York law. He therefore dismissed both terrorism-related counts, including first-degree murder, but retained the second-degree intentional murder charge and the weapons and false-document offences.

Mangione was recognised by employees of a McDonald's restaurant in Altoona, Pennsylvania, and arrested. Authorities stated that he possessed a fake driving licence previously used in New York and recovered a weapon and other items. The circumstances of certain searches of his backpack were subsequently disputed.
