Luigi Mangione's state murder trial is postponed after federal guilty plea

Mangione entered his guilty plea in the federal case without reaching an agreement with prosecutors, and there was no guarantee that his acceptance of responsibility would result in leniency at sentencing.

Mangione is due to be sentenced in his federal case on Dec. 18. Federal prosecutors said on Friday that they intend to seek a life sentence, the maximum allowable.

In the state case, Mangione would face 25 years to life in prison if convicted of second-degree murder.

If Carro decides to dismiss the state case, it would eliminate the possibility of Mangione having to serve consecutive prison sentences in the two cases.

Bennett Gershman, a law professor at Pace University in New York, said it was unlikely Carro would dismiss the case on double jeopardy grounds.
