A soldier accused of killing a New York state trooper and his own wife Sunday allegedly planned a foiled school shooting nearly two decades ago, when he was a middle school student in Michigan.
U.S. Army Staff Sergeant Justin Walters, 32, is charged with fatally shooting New York State Trooper Joel Davis, 36, who responded to a report of shots fired around 8 p.m. at the home. He also allegedly killed his wife Nichole Walters, 27.
