A man charged in a fatal shooting at a New Hampshire country club where authorities say restaurant patrons acted quickly to stop the gunman made a brief initial court appearance Monday and was ordered to return in early October.

One person was killed and two others were wounded by gunfire Saturday at Sky Meadow Country Club in Nashua.

Hunter Nadeau, 23, of Nashua, was taken into custody in a nearby neighborhood and charged with one-count of second-degree murder. Nadeau, a former employee of the club, appeared by video from jail wearing a green smock Monday and spoke only to answer a judge's questions.

Nadeau waived his arraignment, did not enter a plea and was scheduled for a probable cause hearing in early October. The judge said Nadeau had been able to consult with an attorney before an appearance.

Assistant Attorney General Peter Hinckley told reporters after the hearing that authorities were still investigating possible motives but they do not believe the shooting was a targeted attack.

Rob Parsons, the country club's owner, said he was heartbroken over the shooting.

Parsons said Monday he has lived in the golf course community for more than 20 years and has been comforted by the outpouring of support, including more than 3,000 messages. He called DeCesare’s widow “a remarkable woman,” a neighbor, and a friend, and he read a statement from her in which she said she isn’t going anywhere.
