Then the defense will have until Oct. 30 for Mangione's own reply.

Carro set the next adjourned date for Dec. 10.

Due to a difference in state law and the U.S. Constitution, New York's double jeopardy rules are more favorable to Mangione with the federal case resolved.

Manhattan prosecutors, however, have said they plan to continue pursuing their case against him.

The 28-year-old University of Pennsylvania graduate admitted Friday to stalking UnitedHealthcare CEO Brian Thompson across state lines, then shooting him in the back outside a Manhattan hotel where he was supposed to meet with investors.

Thompson was a 50-year-old father of two from Minnesota.

Mangione has not yet been sentenced in the federal case. Sentencing guidelines recommend about 30 years max, but Judge Margaret Garnett is not bound by them. He could still face a maximum of life in prison without parole.

If he goes to trial on the state charges, the top count of second-degree murder carries a maximum potential sentence of 25 years to life in prison.
