Federal Plea Deal Could Derail Mangione's State Trial Under Double Jeopardy

Mangione's defense and federal prosecutors meet August 14 amid reports of plea discussions. If Mangione pleads guilty federally, his attorneys could invoke double jeopardy — reinforced by New York's state constitution — to challenge the separate state trial set for September 8. Former prosecutor Mitchell Epner notes the state cannot prosecute on the same facts once a federal case is completed. No deal is guaranteed.
