Hunter Nadeau is a 23-year-old man identified as the suspect in a deadly shooting at the Sky Meadow Country Club in Nashua, New Hampshire, on September 20, 2025. He has been charged with second-degree murder after allegedly opening fire during a private wedding event, killing 59-year-old Robert Steven DeCesare and injuring two others. There is no known connection between Nadeau and DeCesare. Witnesses reported that Nadeau shouted phrases like "Free Palestine" and "The children are safe" during the attack.
