One person was killed and two others were wounded by gunfire Saturday at Sky Meadow Country Club in Nashua. 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. One of the surviving gunshot victims was an employee and the other was a patron, Formella said. The employee is hospitalized in critical but stable condition while the other victim's status was unknown, prosecutors said Monday.
