Man charged in Sky Meadow Country Club shooting plans insanity defense

A man accused of shooting multiple people inside a Nashua country club last year plans to use an insanity defense.

Hunter Nadeau is charged with first-degree murder in connection with the death of Robert DeCesare in a shooting at Sky Meadow Country Club on Sept. 20, 2025.

According to a police affidavit, Nadeau told investigators after he was taken into custody that before the shooting, he had a sudden urge to kill himself, but he decided to punish the wealthy.

During a hearing in May, the judge gave Nadeau until this week to enter an insanity plea.
