The Fort Drum staff sergeant accused of killing New York State Police Trooper Joel R. Davis last summer during a domestic incident is headed to trial in the fall.

On Wednesday, Justin D. Walters appeared in Jefferson County Court for an evidence suppression hearing in which a trooper testified that Walters told him he “was just trying to scare him” when he allegedly shot Trooper Davis in the driveway of the defendant’s County Route 46 home last July.

Walters also is accused of shooting his wife, Nichole V., 27, multiple times, killing her at their Theresa home on July 9 and injuring her friend, Rebecca Finkle. Trooper Davis was responding to a domestic incident. Finkle has since recovered from her injuries, the Watertown DailyTimes reports.
